Shock Loss After Hair Transplant Surgery

What concerns you most about hair transplant shock loss?

Just as your scalp had healed after your surgical hair restoration, you may be disheartened to see your newly implanted hair falling out. This is commonly known as hair transplant shock loss and can represent a considerable source of stress and anxiety for patients during their hair transplant recovery[1][2].

However, while it may seem concerning, this temporary condition is nothing to worry about. Although your newly implanted hair fibres are falling out, their follicles are healthy and will start producing new hair within a few months.

Executive summary

This article will tell you everything you need to know about hair transplant shock loss. You will learn why this phenomenon happens, what it looks like, how common it is and its typical timeline from onset to recovery. 

Moreover, we will show you how to tell normal hair shedding apart from hair transplant complications that require medical attention. Finally, we will present you with helpful tips and tricks to reduce the duration and intensity of your shock loss and prevent further, unnecessary hair thinning during this stage.  

  • Also known as hair transplant shedding, shock loss is a normal and temporary phenomenon experienced by the vast majority of patients. It represents a fast-paced shedding of the grafted hair that can leave your transplant area looking sparse or fully bald for a few months.
  • While shock loss primarily affects the newly implanted grafts, it can sometimes also affect the native hairs in the donor and transplant areas.
  • Hair transplant shock loss is typically caused by a combination of anagen and telogen effluvium, triggered by the trauma of surgery and the temporary interruption of blood supply to the grafts.
  • You can expect shock loss to start 2-3 weeks after your hair transplant and to see the first signs of hair regrowth within 3-4 months of onset.
  • Not all post-transplant hair loss is caused by shock loss – it can rarely happen due to a complication, such as infection, inflammation or scalp disease. If you notice other concerning symptoms except hair thinning, it is best to tell your surgeon.
  • Factors such as surgical skill, post-op use of hair growth treatments, as well as the patient’s age, health condition and healing capacity can impact the duration and intensity of this phenomenon.
  • Choosing a skilled and experienced surgeon, using hair growth medication consistently, and avoiding smoking pre and post-surgery are the best ways to reduce the duration of hair transplant shock loss.

What causes shock loss after a hair transplant?

Research suggests that shock loss usually occurs as a combination of two similar and temporary conditions that can cause diffuse hair shedding: telogen effluvium and anagen effluvium [1][2][3].

Telogen effluvium

This temporary condition occurs when an excessive proportion of hair follicles go into the telogen (shedding) phase at the same time, causing diffuse hair thinning in the affected area [4]. It is commonly associated with stress and anxiety-induced hair loss. However, a physically demanding event, such as sudden weight loss, an illness or, in this case, a scalp surgery, can trigger it as well (find out more about hair loss after surgery).  Our experienced surgeon, Dr Peter Barron, explains this phenomenon more clearly:

 “Post-transplant shedding” is a recognised phenomenon that happens in almost every post-operative patient, anywhere from 2-4 weeks post-procedure, as the hair follicles enter their resting phase. About 10% of your scalp hair is resting at any one point; however, because follicles do this asynchronously, all over the scalp, we don’t notice it. The single physical stressor of moving transplanted hairs from the donor area to the recipient area, however, synchronises these follicles that have been moved, hence the hair shafts shed at a similar time.

Anagen effluvium

This type of hair shedding is most often associated with medication-induced hair loss (e.g. chemotherapy hair loss). However, it can occur any time there is considerable disruption to the growth (anagen) phase of your hair follicles [5]. Temporary loss of access to resources your hair follicles need to keep producing healthy hair (e.g. being cut off from the blood supply during transplantation) can lead to this phenomenon [3]. Having a greater sensitivity to the local anaesthetic, which can constrict the small blood vessels in your scalp, can also play a role in this condition.  

While anagen and telogen effluvium occur in follicles that are in different stages of the hair growth cycle, they both share the same major symptom: a substantial proportion of your hair temporarily falls out in the affected area.  

Does hair transplant shock loss only affect your newly implanted grafts?

The most visible, severe and often anxiety-inducing post-procedure hair shedding occurs in your transplant area. That is because it is the area most traumatised by surgery, but also the one you are most closely watching. Seeing your newly implanted hair fall out, often alongside some of your native hairs, can be concerning and difficult to ignore until regrowth finally starts, providing relief. 

However,  your donor area can sometimes also be affected by hair transplant shock loss. While this happens less frequently and is often less severe than in the transplant area, you may notice some native hair thinning around your graft harvesting sites. This is especially true if you had FUT surgery, which implies harvesting an entire strip of skin from the back of your head, cutting it up into grafts and suturing the wound [2]. The sizeable incision is a form of trauma to the scalp and may also sometimes sever small blood vessels which nourish the hair follicles in the area. So it is not uncommon to see some temporary hair thinning around the FUT scar or in the donor area in general. Fortunately, your shed hair will grow back in 3-4 months, just like it will in your transplant area.

Hair transplant shock loss timeline

Here is all you need to know about when you can expect your shock loss to start, how long it usually takes and when you can see your hair growing back:

Shock loss timeline

Typical shock loss onset time

As the name suggests, waking up one day to see your freshly transplanted hair falling out can be shocking, even if you are expecting this to happen. There is always one part of us that hopes we will be the exception and that we will be spared this extremely common side effect. Dr Barron captures the emotional charge experienced by patients at the onset of hair transplant shock loss: 

Once they are comfortable, happy and getting used to seeing new hairs on their head (roughly three weeks post-op), it’s all going to be cruelly snatched away from them as the hairs shed and they begin to look similar to their pre-transplant appearance.

A good way to be prepared for this reality is to know when to expect it. Typically, you can expect to see the first signs of shock loss 2-3 weeks after your hair restoration surgery (although some may experience it as late as 4 weeks post-op) [2]. 

Average hair transplant shock loss duration 

Fortunately, this post-surgical dormant stage of your hair follicles doesn’t last very long. After 3-4 short months after your hair transplant, you will be able to see the first signs of regrowth [2]. The new hairs will gradually break through the scalp, each at its own pace. They won’t be visible at first, although you’ll be able to feel them with your fingertips. While initially patchy, your transplanted hair will get denser over the next few months. It should grow as fast and steadily as your native hair. Dr Barron provides more insight into how patients experience this process:

Within the next three to four months, they’ll begin to doubt themselves as to whether the transplant has failed, until one day they’ll start to see small numbers of little hairs begin to wake up in a very patchy manner. At month five or six, there will be one week where the growth should take off, and they’re filled with excitement again as things start to take shape again. Almost every patient tells me how I was right with these predictions whenever they come to see me at follow-up.

When will my hair grow back after shock loss?

Your transplanted hair will grow at different rates, slowly maturing for up to a year (or, in some patients, even eighteen months) before you see the final result of your hair restoration surgery. 

Most qualified, experienced surgeons achieve a graft survival rate of at least 90% [6], so if your procedure was successful, you can expect almost all of your transplanted hair to grow back within the first year and a half post-op.  

Once this process is complete, you will be able to enjoy your long-awaited results for the rest of your life, as well-maintained hair transplants last forever

How common is hair transplant shock loss?

According to the experts, almost all hair transplant patients undergo this temporary shock loss period before being able to enjoy the results of their hair restoration surgery. This phenomenon is encountered in men as well as women and in patients of all ages and types of hair loss. 

There are, of course, a lucky few whose hair follicles are extremely resilient and can withstand the stress of surgery without shedding. However, this is the exception rather than the rule. Researchers found that they make up less than 5% of all hair transplant patients [2]. So it’s best to be mentally prepared to experience some shock loss after your procedure.   

What does hair transplant shock loss look like?

The only visible symptom of shock loss is a rapid and pronounced hair shedding. Patients undergoing this phase of their hair transplant recovery should not experience any other scalp symptoms, such as inflammation, crusting, flaking, or a rash. On rare occasions, mild scalp burning (trichodynia) has also been reported. While some hair transplant redness may still persist, it is a different side effect of the procedure, unrelated to the shock loss.

In most cases, during this stage, you can expect your transplant area to look similar to the way it did pre-surgery. Moreover, some patients may experience even lower hair density than they had pre-surgery if some of their native hairs are also affected by shock loss.

How much hair may fall out during hair transplant shock loss?

When it comes to your grafts, it is common to shed the majority of the newly implanted hair in your transplant area. However, some of the native hair that was already there since the hair transplant may fall out as well, as a result of telogen effluvium. Dr Barron paints a clear picture of the most common scenario:    

Expect almost 100% of the transplanted follicles to shed and potentially even some native hairs in the surrounding area.

Moreover, especially if you had FUT surgery, you may experience some visible shock loss in your donor area as well, especially around your scar. 

Factors that affect hair transplant shock loss intensity and duration

While most patients experience shock loss after their hair restoration surgery, some patients are at a higher risk of developing more severe shedding than others. Here are some of the factors that can influence shock loss intensity and duration [2][7]:

  • Hair transplant volume  – patients who require a large number of grafts (e.g. an over 4000 graft hair transplant) may experience more severe shock loss, especially if they undergo a megasession.These high-volume procedures require larger quantities of local anaesthetic and cause more extensive trauma to the scalp. 
  • The surgeon’s skill and experience – highly trained surgeons with decades of practice know what to do and what to avoid so your shedding phase is as brief and mild as possible (to be discussed). 
  • The patient’s age and regenerative capacities – younger people typically have better healing and regeneration abilities than older ones. Moreover, due to genetics, overall health and lifestyle, some individuals heal faster and/or have more resilient hair follicles than others. 
  • The use of hair growth medications postoperatively – research shows that using hair growth medication such as Minoxidil and Finasteride before and after your hair transplant can reduce the duration and intensity of shock loss. 

Signs of complications vs hair transplant shock loss

While this procedure is generally safe and successful, hair transplants still carry some risks. A small number of patients encounter complications, some of which can cause hair loss. If they occur alongside shock loss (or around the time you are expecting its onset), they can be mistaken for normal post-surgical shedding. Here are a few complication signs which should never be ignored, or attributed to shock loss without discussing them with your surgeon [1] [2] [8]:

  • Pain, inflammation, and/or tenderness in the affected area of the scalp, especially if it does not improve within 2-3 days – you should experience no further pain or discomfort in your transplant area after the initial few days of post-op healing.
  • Intense itching or burning in the transplant area – telogen effluvium can sometimes cause burning scalp syndrome, but it should be mild and not progress over time. 
  • Pus, red bumps or pimples around your hair roots  – these are often the mark of a hair follicle infection, such as folliculitis after a hair transplant. They require monitoring, adequate home care and sometimes medical treatment so they don’t affect your graft survival.  
  • Crusts or flaking on your transplant area – their presence may be a sign that a common scalp problem, such as seborrheic dermatitis or scalp psoriasis, is flaring up and requires care to avoid negative consequences to your grafts. 
  • A rash on the scalp, sometimes accompanied by swelling – this may be a sign of contact (allergic) dermatitis. Your surgeon may recommend that you take an antihistamine and possibly other medication as well, so the resulting scalp inflammation does not impact your hair transplant results.
  • A discolouration of the scalp – while some leftover scalp redness is still normal at this point in your recovery, alert your surgeon immediately if you notice a dark-coloured area on your scalp. It could be a sign of skin necrosis, a very rare but serious hair transplant side effect.

Can you prevent or reduce hair transplant shock loss?

Shock loss is a normal part of recovery after hair restoration surgery, and it cannot be fully prevented. However, some things can help reduce the duration and, in some cases, the intensity of your hair shedding:

How your surgeon’s skill and experience can reduce shock loss

An inexperienced surgeon can do things that inadvertently make your hair transplant shock loss more severe, such as [2]:

  • Poorly executed incisions that lead to wound tension
  • Using too much local anaesthetic (especially during megasessions)
  • Excessive surgical manipulation
  • Accidental severing of neurovascular bundles
  • Harvesting between previous scars

However, experienced surgeons use a specific Shock Loss Prevention Protocol, meant to reduce the duration and severity of this phenomenon. This starts by performing a thorough dermoscopy of the recipient area and taking note of the properties of the native hair. Then, during surgery, being mindful of the following aspects:

  • Avoiding accidental injury to the small blood vessels and nerves in the scalp when creating the incisions where the grafts will be implanted
  • Aligning the incisions perfectly with the native hairs and preserving enough room between the grafts and the native hairs.
  • Implanting grafts with an angle and direction that are parallel to that of existing hair.
  • Storing the harvested grafts in a saline solution or, preferably, in platelet-rich plasma before implantation (using platelet-rich plasma can improve hair transplant results).
  • Keeping graft density under 25 follicular units/square centimetre to avoid packing them too densely. 

As you can see, choosing an experienced surgeon to perform your procedure can have a considerable impact on your recovery process, as well as your results. If you want to be sure you are in the best possible hands, book a free hair transplant consultation with one of the world-class surgeons at the Wimpole Clinic. Their undeniable excellence is one of the main reasons we were voted Hair Transplant Clinic of the Year for 4 years running (2021-2024). 

How proper aftercare can reduce hair transplant shock loss 

Science shows there are 3 main things you can do to help improve your shock loss and reduce its duration:

  • Use hair growth medication as recommended by your surgeon – one of the common hair transplant aftercare recommendations is to use hair loss treatments such as Minoxidil and Finasteride in the long term [7]. Studies show that using them post-op can reduce the intensity and duration of your shock loss.
  • Get platelet-rich plasma (PRP) therapy – studies [9][10] show that getting PRP after your hair transplant can reduce the duration of your hair follicle’s dormant phase, helping them grow back sooner. However, you need to wait at least a month after your surgery before you can safely get PRP hair treatment
  • Stop smoking – you may have heard that smoking can cause hair loss, because nicotine can reduce blood flow to your hair follicles and cause inflammation [11]. But did you know that smoking can negatively influence your hair transplant results? Inhaling nicotine soon after your surgery can slow down your healing and reduce the vital blood flow your grafts need to become attached and survive [12]. Moreover, it can prolong and worsen your shock loss.     

Aside from this, there are a few more things you can do to prevent further stress to your hair follicles, which may cause additional, unnecessary hair loss:

  • Get enough rest, so you can heal and recover quickly after your procedure
  • Eat a healthy, balanced diet that keeps hair loss-inducing vitamin deficiencies away
  • Keep your stress and anxiety levels under control by engaging in relaxing activities (hobbies, spending time with loved ones, walking in nature, psychotherapy, etc.)

Can you treat hair transplant shock loss?

Normally, this common phenomenon requires no treatment, as it resolves over time without any kind of medical intervention. As stated above, hair growth medications and therapies can help shorten its duration, but your hair will still grow back within a few months even without using them.  

No presently known treatment can make your shed hair grow back overnight or even sooner than at least 2 months post-transplant. Your hair follicles need to rest and recover after your surgery, and there is presently no known way to rush them right back into hair production.

Can hair transplant shock loss become permanent?

While shock hair loss sounds dramatic, the hair shedding is almost always temporary. So, although it might cause you some anxiety initially, as long as you are following your post-surgery care advice, there is no need to worry, and the hair will grow back thick, full, and healthy.

If your hair does not grow back after shedding (or remains patchy even after a year or more), it is not because of the shock loss. It is a sign that your hair transplant has failed. That happens when a significant proportion of your implanted grafts have not survived. Unfortunately, this can only be fixed with a second hair transplant

However, you can rest assured that this situation is extremely rare if you choose an experienced surgeon. We, at the Wimpole Clinic, are proud to report a 97-100% hair transplant success rate.  

When to call your surgeon about hair transplant shock loss?

Normally, hair transplant shock loss should come and go on its own, with no need for medical intervention. However, be sure to let your surgeon know as soon as possible if you experience any of the following:

  • Shedding on your transplant area that occurs during the first week post-op (especially if accompanied by bleeding at the shedding site).
  • Hair shedding that is accompanied by other symptoms (scalp inflammation, pain or tenderness, pimples, bumps or pus around your graft roots, a rash, etc.)
  • Complete absence of hair regrowth 5 months or more after the onset of shock loss

Frequently asked questions

No, the presence or absence of shock loss does not influence your hair transplant results in any way. So if you are among the lucky few who were spared this stage, feel free to relax and enjoy it – you are just as likely to achieve an excellent outcome as those who experienced hair shedding. 

While some people experience Minoxidil hair shedding within 2 weeks of first starting this treatment, it is the same kind of temporary hair shedding you would be experiencing around this time anyway and lasts a similar period. In some situations, it may push a few more of your follicles into a dormant state than would normally enter it. However, research shows that using Minoxidil reduces the overall duration of shock loss. 

Some patients experience an almost 100% shedding of their implanted hair during shock loss and they may even develop some shock loss on their donor area as well. However, you are unlikely to become fully bald. The shock loss is normally only that severe in your transplant area. In most cases, during this stage of recovery, your hair will look similar to its pre-surgery appearance.

The surgical method (FUT vs FUE) should not influence the shock loss in your transplant area, as both use the same implantation techniques. However, since the harvesting method is different, FUT may indeed carry a higher risk of donor area shedding than FUE, as the surgery is more invasive and has a longer recovery time. 

Yes, since every person is unique, some patients can start experiencing shock loss a bit later than 3 weeks after their hair transplant. However, if more than 6 weeks have passed since your procedure and you are suddenly starting to experience new hair loss, it is best to let your surgeon know, as it may have a different cause.
