Wondering whether hairspray is bad for your hair?. It makes sense —  a few decades ago, hairspray contained harmful substances, many of which could hurt your lungs, damage your hair, and even cause cancer [1-4]. Fortunately, regulations and products have changed dramatically, so these days hairspray is unlikely to do any serious harm to your hair (or your body) when used in moderation [3, 5]. 

However, while hairspray isn’t known to cause hair loss or significant damage with typical use, it may lead to minor hair problems when applied excessively. The most common issues are  product build-up, dry, brittle hair, and scalp irritation [5].

What does hairspray contain and is it safe to use? 

Hairspray is a styling product used to lock your hairdo into the desired shape and provide your hair with additional volume. It usually contains the following ingredients [3]:

  • Film-forming polymers,  — Molecular chains that coat the hair shafts and dry, fixing them in place.
  • Solvents (alcohol or water) — Solvents act as a carrier for other ingredients. When hairspray is applied, the solvents evaporate, leaving the polymers in place.
  • Propellants — Substances that help the fluid leave the aerosol can.
  • Additives — Some hairspray products contain protective or supplementary substances like (silicones, vitamins, and UV protectors).
  •  Fragrances — These add perfumed scents to your hair. 

UK aerosol products like hairspray must conform to the Aerosol Dispensers Directive. This is shown in the CE symbol on the packaging (or, from December 2024, the UK Conformity Assessed marking). These symbols show that the product is safe for sale and use in the UK.

However, while these products are generally safe, some ingredients can have a detrimental effect on your hair.

Styling hair with hairspray

Is hairspray bad for your hair?

If applied correctly and not overused, most commercially available hairsprays are relatively harmless to your hair. Increased oversight in the cosmetic industry has led to the removal of dangerous chemicals, which have been replaced with safer alternatives.

However, if you use hairspray frequently and/or in large quantities, it may have a negative impact on your hair and scalp:

  • It can build up and leave residue on your scalp – if you apply hairspray often and don’t wash your hair regularly in between uses, polymers can mix with dust and dirt from the environment and produce buildup [5]. This can make your hair look dull and unhealthy, produce flaking that resembles dandruff, and may also clog your pores and hair follicles, leading to common scalp problems, such as acne or scalp folliculitis
  • It can dry up your hair – since most hairspray products contain alcohol and some contain silicates as well, overuse can remove hair moisture, leaving it dry and more vulnerable to mechanical hair breakage. If this happens, you may want to invest in a good shampoo for dry hair
  • It can alter your hair shade – while hairsprays don’t physically modify your hair colour, applying a large quantity can level the natural tilt of your hair cuticles. This can affect the angle at which light reflects off your strands, changing the perception of your hair colour. Research shows that hairsprays with stronger holds are more likely to produce this effect than lighter ones [6].
Types of hairspray

Does hairspray cause hair loss?

Generally, hairspray doesn’t cause hair loss. So if your hair is thinning and you’re not sure why, speak to a hair doctor about the possible causes of hair loss.

If your hairspray habit starts to damage your hair, it can cause hair breakage. This occurs when the ends of your hair become so brittle that they snap off. When this happens en masse, it can make your hair look thinner, though it’s not technically true hair loss.

Is it bad to use hairspray everyday?

Using hairspray everyday isn’t great for your hair. While the ingredients are relatively nontoxic, exposing your hair to drying agents like alcohol everyday could cause your hair to snap, fray, or split sooner than if you weren’t using hairspray so often.

This is especially true if you don’t wash your hair everyday to remove the remaining product and any build-up.

If you’re relying on hairspray to maintain your style on a daily basis, consider changing your hairstyle to a lower maintenance look such as these wash and wear haircuts for women.

Alternatively, embrace your natural hair texture and curl pattern (or lack thereof) with appropriate hair products, so you don’t need to use hairspray to fix your style in place. Take our hair type quiz to get a better understanding of your hair and how to look after it.

Is leaving hairspray in your hair bad?

Ideally, you shouldn’t leave hairspray in your hair for longer than a day. It’s recommended that you wash your hair in the evening after wearing hairspray for a day. (Don’t worry, washing your hair daily won’t cause hair loss — that’s just a myth.) This is important because:

  • It removes build-up or residue that settles on your scalp, leading to irritation, tenderness, and flaking.
  • You’ll need to pull your brush harshly through dry hairsprayed hair the next morning, causing mechanical damage.
  • Some products can stain your bedding if left on overnight.

Leaving hairspray in overnight every so often isn’t going to cause serious problems. If you do need to skip a wash, shampoo your hair twice the next day to remove all the residue. Leave your conditioning treatment on for a little longer for a hydration boost.

Is it safer to use water-based or alcohol-based hairsprays?

Solvents in hairspray products act as carriers for the other ingredients. The two major kinds of hairspray solvents are alcohol and water. Here’s how they differ: 

  • Alcohol-based – Most commercially available hairsprays contain alcohol, such as ethanol or isopropanol. Overuse of alcohols in hair products can lead to dry, brittle hair. Moreover, isopropanol is a volatile organic compound so it can have a negative environmental impact [7].
  • Water-based – Some hairsprays have completely eliminated alcohol from their formulas and replaced it with water. This option can be healthier for your hair and better for the environment. However, alcohol-free hairspray tends to be stickier and takes longer to dry than alcohol-based hairsprays.

Both options are safe to use in moderation. For daily use, water-based products generally cause less damage to your hair, though they won’t give you quite the same look and feel as you’re used to with an alcohol-based hairspray. 

How to apply hairspray correctly

How to apply hair spray correctly?

Since there are many kinds of hairspray, it’s important is to read and follow the instructions on your product. However, here are some general tips on the best way to apply hairspray without causing undue damage:

  1. Make sure the nozzle is clean and not blocked by hardened product before use.
  2. Dry your hair before applying hairspray, to ensure your hairstyle looks the way you want it to.  
  3. Hold the spray bottle approximately 30 cm away from your hair during application.
  4. Keep your eyes closed while spraying the product on your hair.
  5. Spray in shorter bursts on the areas where you need it rather than one long, continuous press. 
  6. Clean the nozzle after you finish using your hairspray. 

Mistakes to avoid when using hairspray

Here are some of the most common errors to avoid when applying hairspray to create your favourite style:

  • Using too much hairspray – You don’t need to add a lot of product for it to be effective in holding your style. On the contrary, using too much can overload your hair, making it look hard and unnatural.
  • Applying hairspray before heat styling – While excessive heat styling is not good for your hair under any circumstances, using it on hairspray can increase the risk of overdrying and damaging your strands. 
  • Applying hairspray from the wrong distance – Holding the bottle less than 25-28 cm away during use can weigh your hair down and make it look dull, while holding it more than 33-35 cm away can render it less effective.
  • Using hairspray too frequently – If you are constantly reapplying hairspray throughout the day, you may increase the risk of getting dry hair and irritating your scalp. Not washing regularly between applications can lead to product buildup and skin irritation. 
  • Combing hairsprayed hair– Brushing or combing your hair after you’ve applied hairspray can cause split ends instead of healthy hair. It can also lead to hair breakage.

Hair spray alternatives you can use

Other products can hold your hair in place without the use of alcohol or other damaging ingredients. Here are some of the most popular hairspray alternatives [5]:

  • Hair mousse – Mousses are usually applied to wet hair, and provide hair volume when blow-dried. They contain very similar ingredients to hairsprays.
  • Hair gel – Gels can be applied to wet or dry hair. They’re available in a wide variety of hold strengths and often contain glycerin or a similar moisturiser, to create a wet look.    
  • Hair waxes and clays – These products are used to achieve a strong hold and create special, more elaborate hairstyles. They can contain natural ingredients (e.g. beeswax) or synthetic options (e.g. polyethylene glycol). Applying them skilfully to achieve the look you want can be more difficult than with other hair cosmetics;
  • Hair creams, pomades and emulsions – Depending on the effect you want, different types of hair creams can provide a variety of holds and texturising effects. They normally contain a water-repellant base such as wax or oil and emulsifiers.  Depending on the formulation, they may also contain polymers, thickeners, or texturising agents such as bentonite. These creams are often used as finishing touches after styling.

Is it better to not use hairspray?

There’s definitely a place for hairspray if your style needs a little extra hold. But you should be aware of the impact of frequent use and/or leaving it in your hair too long.

Using a small amount of hairspray to lock in your style every so often is unlikely to cause serious damage to your hair. It’s fine to continue using your hairspray sparingly provided your hair isn’t already excessively dry or damaged.

Hair products that can damage your hair

Hair products that can damage your hair

While hairspray is mostly safe to use in styling, there are hair products that can cause more significant damage with overuse. For example, frequently using bleach or hair dye can cause hair loss. Harsh chemicals can penetrate the hair shaft, affecting its structure and making it easy to break off. Moreover, certain stronger formulations can irritate your scalp and even cause hair shedding from the roots.

 As a rule, it is a good idea to avoid frequent use of hair products that contain the following substances, as they can harm your hair and scalp:

  • Ammonia – When used frequently, this common hair dye ingredient can dry out your hair and damage its cuticles. In some cases, it can also irritate your scalp [8]. 
  • Hydrogen peroxide – Often found in hair bleach and hair dye, this chemical increases oxidative stress on your hair, potentially causing hair loss and dermatitis with frequent use [9].
  • Sodium lauryl sulphate or sodium laureth sulphate – These powerful detergents can be found in shampoos and other cleansing products. They can strip the beneficial oils from your hair, leaving it dry and brittle. 
  • Alcohol – Many hair products contain alcohol as solvents, thickening agents, or propellants. When used in large quantities, alcohol can dry out your hair, exposing it to mechanical damage.  
  • Dimethicone – This type of silicone can make your hair soft and shiny, but it can also dry and irritate your scalp with frequent use. 
Woman concerned with hair health

Are you concerned about your hair health?

While excessive or improper use can lead to fragility and breakage, hairspray is unlikely to cause damaged hair or hair loss by itself. So it’s important to understand what’s causing your hair problems if you’re worried about the condition of your hair.

Book a consultation with a trichologist at the Wimpole Clinic for a thorough assessment. They’ll  examine your hair and scalp and may request blood tests for hair loss to provide you with an accurate diagnosis and effective treatment.

If your hair thinning is caused by overuse of styling products that contain harsh chemicals, they will recommend a safe, healthy, personalised hair-care regimen for your hair type, ensuring you get the best available treatment.

FAQs

Learn more about hairspray in these frequently asked questions.

If used appropriately, hairspray should not normally cause any damage to your lungs. In the past, inhaling its aerosols regularly could indeed cause buildup in your airways, trouble breathing, coughing and pulmonary issues [4].

However, since the tightening of regulations regarding the type and amount of volatile organic compounds hairspray is allowed to contain, lung issues caused by inhaling its droplets have become very rare [3].

In recent years, much more thorough regulations and verifications have been set in place for cosmetic products in the Western world and most substances that can cause cancer have been replaced with safer alternatives. That is why it is unlikely that your hairspray contains carcinogens.

However, if you purchase this type of hair product from a part of the world where such regulations don’t exist or are not enforced, there is some risk that it could contain substances that may increase your risk of developing cancer, such as benzene, vinyl chloride, and methylene chloride [10]. If you want to be on the safe side, opt for non-aerosol hairspray, as most of these harmful substances are used as propellants.  

The main benefit to using hairspray is keeping your hair locked in place for longer. It’s unlikely to offer any other advantages, even if your chosen product is infused with certain protective additives. These may offset some of the negative effects of the hairspray, but probably won’t give you any long-lasting benefits.
