Platelet-rich plasma (PRP) hair treatment is an effective treatment for hair loss. It involves harvesting regenerative cells from your blood and reinjecting them to areas of thinning hair to encourage regrowth and regeneration. 

Research shows encouraging results with regard to the success rate of PRP hair treatment. While not all studies agree that PRP therapy is the best hair loss treatment for men or women, many have shown it to be both safe and effective. In one study, 93% of male pattern baldness patients said their hair loss stopped as early as two months after starting PRP hair treatment [1].

Another study that measured the success of PRP hair therapy using the hair pull test found the test became negative in more than 95% of patients after six months of PRP therapy combined with hair growth medication — higher than the group using medication alone [2]. Additionally, 68% of clinicians reported new hair growth following PRP treatment in their patients, while 45% noted improvements in hair thickness [3].

Together, these stats indicate a moderately strong success rate for PRP hair treatment. Many other studies corroborate these findings, while some call them into question. In this article, you’ll discover:

  • The results of several clinical studies into the effects of PRP hair therapy.
  • How effective it is to combine PRP treatment with other hair loss therapies.
  • How to increase the success rate of PRP treatment for hair growth.

What is PRP hair treatment?

PRP therapy has been used for years to successfully treat musculoskeletal problems, such as damage to tendons, muscles, and ligaments. More recently, it has gained attention as a potential solution to hair loss and skin problems. 

Platelet-rich plasma is retrieved from your blood and used to stimulate hair growth via the following steps:

  • Step 1 – A blood sample is taken from your arm and placed in a centrifuge. This machine separates the different components of blood according to their densities. 
  • Step 2 – The centrifuge spins for about 10 minutes until the different components of blood have been separated. The platelet-rich plasma is harvested and placed into a syringe. 
  • Step 3 – The PRP is administered immediately via several injections to the scalp. The injections are given to areas of thinning hair to encourage regrowth and regeneration. 
  • Step 4 – This process is repeated several times over the course of 3-6 months. After that, a single maintenance session will be required every 4-6 months to maintain results. Take a look at the results after 3 months of PRP therapy for hair loss.
PRP hair treatment success rate

What is the success rate of PRP hair treatment?

Success rates of PRP hair treatment differ depending on the measure of success and the type of hair loss being tackled. Research into PRP hair treatment has focused heavily on its effects on androgenetic alopecia (AGA), also known as male or female pattern baldness

However, studies have also begun to explore the role of PRP in treating other types of hair loss. Here, we’ll look at the success rate of PRP hair treatment by condition. 

Androgenetic alopecia 

This condition affects up to 80% of men and 50% of women in the course of their life [4] and causes progressive hair loss on the scalp, starting any time after puberty. In men, hair loss tends to affect the crown of the head and frontotemporal regions. In women, there is hair loss at the crown and top of the head, which appears as a wider centre parting.

Alopecia treatment

Let’s take a look at some of the key findings from studies into PRP hair treatment for AGA:

  • Patients in a 2022 study were satisfied with the results of their PRP hair therapy, with average satisfaction rated 7.29 on a scale from 0 to 10 [3]. 
  • Patients treated with PRP therapy saw a 7.7% increase in hair count after 12 weeks [5].
  • PRP-treated scalps showed a 13.2% increase in hair density at 5 months (although scalps treated with placebo showed similar increases at this point, too) [6].
  • 79% of pattern baldness patients declared a noticeable decrease in the amount of hair loss after PRP therapy [7].
  • 93% of 30 male pattern baldness patients said their hair loss had completely stopped as early as two months after beginning PRP therapy [1].

Find out more about the details of these studies below.

A 2022 study investigated patient satisfaction and clinical effects of PRP for AGA [3]. 57% of participants were male and 43% were female. In general, patients were satisfied with the results, with average satisfaction at 7.29 on a scale from 0 to 10. 

There was an average score of 8 (on a scale of 1 to 10) when patients ranked how likely they were to recommend PRP to friends and family. Improvements were noted in hair thickness, density, quality, new hair growth, and less hair loss. 

Another 2022 study reviewed 17 recent clinical trials of PRP hair treatment for  AGA. Studies on PRP for both male and female pattern baldness were included. It concluded that PRP is a highly effective treatment for AGA that can be improved even further when combined with standard care treatments such as Minoxidil and Finasteride [8].

Studies [5] and [6] were included within this review:

  • Study [5] compared the results of 2% Minoxidil versus PRP hair treatment in 20 women over the course of 12 weeks. In women with pattern baldness, PRP was shown to be an effective treatment, though results were weaker than for those using Minoxidil.
  • Study [6] examined the impact of three monthly PRP injections for hair growth in 35 participants with AGA. They used a split-scalp method, in which PRP was injected into one side of the scalp while a placebo (saline solution) was administered to the other. While the placebo appeared to offer similar success rates, researchers noted that PRP may have affected both sides of the scalp due to this study method.

Many trials also showed that PRP is more effective and acts faster than topical Minoxidil and oral Finasteride. There were a few trials that did not support the use of PRP for AGA treatment, but these were heavily outweighed by trials that showed positive results. 

A 2017 study analysed the literature available at the time to see whether PRP was effective for AGA [9]. The results of the 12 studies suggested that PRP effectively increases hair density and diameter. Ten of the 12 studies had positive outcomes for PRP as a hair loss treatment.

Studies [7] and [8] were included within this review:  

  • Study [7] measured patient satisfaction scores following a year of PRP therapy for hair loss. They found that 15 of 19 patients declared a noticeable decrease in hair loss, while 13 of 19 said there was a noticeable increase in hair quality. 11 patients said they would continue with PRP hair treatment.
  • Study [8] asked 30 male patients aged 25 to 35 to evaluate their hair after six months of PRP treatment. 93.3% reported their hair loss completely stopped as early as two months of treatment. Two-thirds reported an increase in hair growth, while 36% also noticed improved hair texture.

PRP for hair transplant recovery

There are two main types of hair transplant: FUE (Follicular Unit Extraction) and FUT (Follicular Unit Transplantation). Our highly experienced hair transplant surgeons at Wimpole Clinic offer both methods. 

In general, FUE is best suited for people who need a smaller number of hair grafts and want a procedure with minimal scarring and a fast recovery time. FUT is best for people who need more extensive hair grafts and are okay with a slower recovery time.

There has been some initial research into the use of PRP to improve recovery after a hair transplant. Studies suggest PRP treatment in conjunction with an FUE hair transplant can promote healing, activate hair grafts, and increase hair density [10]. Researchers have found positive effects from preserving grafts in a PRP solution and injecting PRP into the scalp during or after surgery.

Here are some of the key findings from the existing research into PRP for hair transplant recovery:

  • When PRP was administered during hair transplant surgery, 100% of PRP patients saw >75% hair regrowth after six months of treatment, compared with just 20% in the non-PRP group [11].
  • Steeping hair grafts in platelet-rich plasma during graft preparation can also encourage better results after a hair transplant. Hair graft uptake in those with PRP-treated grafts was 93.3%, versus 76.6% in those with saline-treated grafts [10]. 
  • Patients using PRP for hair transplant recovery had faster improvements in hair density and skin recovery than those not using PRP [11].

This 2016 study looked at the effects of PRP therapy during FUE hair transplant [11]. It was found that patients who received PRP therapy during their transplant saw longer newly erupting hair shafts, faster increases in hair density, better skin recovery at the recipient site, and increased activation of dormant hair follicles.

This 2020 study looked at the use of PRP as a preservation solution for hair transplant rather than as an injection into the scalp [10]. It compared the difference between preserving hair grafts in PRP before implantation versus preserving hair grafts in saline solution. 

Patients whose hair grafts were preserved in PRP experienced faster improvements in hair density and skin recovery than those in the saline group. One year after surgery, their hair uptake and hair thickness were still significantly better than the saline group.

Alopecia areata

Alopecia areata is an autoimmune disease in which your immune system attacks your hair follicles. It usually affects the head and face, although it can cause hair loss anywhere on your body. 

Alopecia areata is the second most common form of hair loss, after female and male pattern baldness. It causes patchy hair loss in the areas it affects, although some people lose all their hair on their scalp. 

Here are some of the key findings and success rates from the existing research:

  • 45 to 60% of alopecia areata patients saw complete remission of their conditionwithin a year of PRP treatment [12]. 
  • Most studies show no difference in results from using PRP for alopecia areata versus triamcinolone acetonide, a first-line steroid treatment for this condition [12].
  • PRP therapy can increase hair regrowth, decrease hair breakage, and reduce burning or itching associated with alopecia areata [13].

A 2022 study analysed the available research on PRP as a treatment for alopecia areata and concluded that PRP is a promising steroid-free treatment for the condition. There were no differences in outcomes between treatment with PRP and triamcinolone acetonide (TrA), a topical steroid that is usually the first line of treatment for alopecia areata [12].

A 2013 study examined the effects of PRP on alopecia areata. It suggests that, although more research is needed in this area, PRP appears to be a safe and effective treatment [13]. 

Can I combine PRP with other hair loss treatments?

PRP often has more noticeable results when combined with other hair loss treatments [2]. These include hair transplants, medications and lifestyle changes. Here, we’ll explore these treatments in more detail and how they can be combined with PRP.

Hair transplant

Although PRP can have great results as a hair loss treatment, a hair transplant may be necessary for more extensive hair loss. In addition, a hair transplant can give you permanent regrowth, unlike PRP, which requires top-up sessions to maintain results. 

When combined with a hair transplant, PRP improves recovery time, skin discolouration, and final hair thickness and length. A hair transplant with PRP injections before, during, or after surgery can provides an effective and comprehensive cure for hair loss [14]. 

PRP hair treatment alternative therapies

Finasteride

Finasteride works by stopping testosterone (a sex hormone) from converting to another hormone called dihydrotestosterone (DHT) [15]. DHT can stop hair growth and cause hair loss. By stopping its production, Finasteride can prevent hair loss and encourage hair growth. 

PRP is generally safe to combine with Finasteride, though women are advised not to take Finasteride in most cases as there are more serious potential risks.

Minoxidil

Minoxidil can reverse male or female pattern baldness through the following mechanisms: 

  • Increasing blood flow around hair follicles
  • Extends the growth phase of each follicle
  • Stimulates hair follicles into the growth phase
  • Reverses miniaturisation of follicles (when the hair follicle constricts, making it harder for hair to grow)

Research shows PRP therapy and Minoxidil combined have greater effects as a treatment for androgenetic alopecia than when used individually [16]. Your clinician can advise you on which medications are suitable for you and which can be combined with PRP therapy. 

How can I increase the success rate of PRP hair treatment?

In addition to combining PRP with complementary therapies, you can make several lifestyle changes to increase the impact of PRP hair treatment. Here are some of the areas to focus on.

Nutrition

PRP therapy relies on your body’s ability to create healthy blood cells, which are influenced by your nutrient levels. Including more leafy, green vegetables in your diet provides you with essential vitamins and minerals that help with the production of healthy blood cells. Examples include brussel sprouts, spinach, cabbage, kale, and others. 

How to increase PRP hair treatment success

A healthy blood supply and good blood oxygenation can stimulate blood flow to the scalp. Improved blood flow to the scalp improves hair growth and reduces hair loss [17].

Exercise

Aerobic exercise before PRP therapy improves the efficiency of your cardiovascular system, increasing blood flow. Research shows just 20 minutes of vigorous exercise temporarily increases the quantity of platelets in PRP (though the platelet-rich plasma must be extracted very soon after exercising to take advantage of this increase, which isn’t always practical or possible) [18].

Avoid smoking and drinking alcohol

Smoking and drinking alcohol have a negative effect on your immune system and ability to heal. Smoking and drinking before, during, or after the PRP process may reduce the benefits you experience.

FAQs

Find out more about the success rates of PRP hair therapy in these frequently asked questions. 

No, but it’s rare to find a treatment for any condition that boasts a 100% success rate. PRP won’t work in 100% of cases, but studies show that it can be very effective for hair loss patients, especially when combined with other medical therapies.

There’s no single answer to this question — it depends on how many treatments you’ve had and how long it’s been since your last treatment. According to one study, 80% of patients retained their hair benefits a year after their last treatment [19]. However, another found that hair density started to decline six months after the start of a PRP treatment course [20].

No — PRP hair therapy results aren’t permanent, but top-up treatments can prolong your results. 

As a patient, the only way to tell if your PRP hair treatment is working is by monitoring your hair for signs of regrowth or slowing hair loss. This normally takes several months (at least three, but often six to nine). Your clinic may be able to give you additional insights, so speak to them if you’re concerned your treatment isn’t working.
