The Best Hair Spray: Real Hold Without Stiff, Brittle Hair

Hair spray is a solution of film-forming polymers, usually dissolved in alcohol, sometimes with water, conditioners and fragrance. When you spray it, tiny droplets land on the hair. The solvent evaporates within seconds, and the polymer left behind forms microscopic welds where strands cross or touch. Those welds hold the hair in the shape you styled it.

How much hold you get depends on the amount and type of polymer, how fine the mist is, and how much you apply. More polymer and more welds mean firmer hold, but also a stiffer feel. Flexible sprays use polymers that stay slightly elastic, so the welds bend instead of breaking when hair moves. Strong sprays use firmer films that resist wind and gravity but feel more set.

Humidity is hair spray's main enemy. Many hair spray polymers are at least partly water-soluble, which is why they wash out with shampoo, but it also means moisture in the air can soften the film over the day. Humidity-resistant formulas use polymers designed to stay firm in damp air. That is why a strong-hold spray matters most in humid climates.

Mist size matters more than most people realize. A very fine mist spreads polymer thinly and evenly over the surface of the hair, giving hold without heavy, sticky patches. Coarser droplets put more product in fewer places, which feels stiffer and heavier. This is one of the biggest differences between aerosols and pumps, and between a cheap spray and a great one.

Light and flexible holds keep hair in place while letting it move. They are best for everyday styles, loose waves, taming flyaways and fine hair, and they brush out easily. If you want a style that looks natural and touchable, start here, and layer more if needed rather than reaching for a stronger spray.

Medium holds are the all-rounders. They keep a blowout or curls in shape through a normal day and tame frizz without making hair stiff. Most people who use hair spray daily will be happiest in this range, and sprays like Elnett and Oribe Superfine are good examples of strong-enough hold that still feels soft.

Strong and extreme holds lock styles in place against wind, humidity and gravity. They are ideal for updos, big volume, events and thick hair that drops curls quickly. They also feel the most set, can look stiff if overapplied, and are the most likely to cause breakage if you brush through them.

There is no standard scale across brands. One brand's medium can be another's strong, and some brands number their sprays. Read the description, start with less than you think, and remember that technique, especially layering light coats and spraying from a distance, changes the result more than the number on the can.

Aerosol hair sprays use a pressurized propellant gas to push the product out as a very fine, dry mist. That mist spreads evenly, dries quickly and gives a lighter feel for the amount of hold. Non-aerosol pump sprays use a mechanical pump instead, producing larger, wetter droplets. They contain no propellant, but they need more careful application to avoid stiff patches.

Aerosols drew scrutiny after the benzene recalls of 2021 and 2022. In December 2021, Procter & Gamble recalled aerosol dry shampoo and dry conditioner products from brands including Pantene, Aussie and Herbal Essences after benzene was detected in some batches. In October 2022, Unilever recalled select lots of aerosol dry shampoo from brands including Dove, Nexxus, Suave, TIGI and TRESemmé made before October 2021, and traced the contamination to the propellant.

Those recalls involved dry shampoos, not hair sprays, and they were limited to specific lots. Benzene was not an ingredient; it was a contaminant from the propellant supply. The episode prompted wider attention to propellant purity across aerosol personal care products, which is a reasonable thing to keep in mind with any aerosol.

If you want to avoid the question entirely, choose a non-aerosol pump spray such as TRESemmé's. If you prefer an aerosol's finer mist, buy from established brands, avoid very old cans, and use it in a well-ventilated room. Either way, close your eyes, avoid breathing in the mist, and keep aerosols away from flames and heat, since they are flammable.

Fine and thinning hair has two problems with hair spray. Heavy sprays weigh it down, so styles collapse flat against the scalp, and strong sprays set it stiff, so brushing out snaps strands that you cannot afford to lose. The goal is to get hold from the lightest possible film.

Choose a flexible or light hold, and hold the can or bottle farther away than you think, around 10 to 12 inches. That spreads the mist thinly and avoids wet patches that clump fine strands together and show the scalp. Build two or three light passes instead of one heavy one, letting each dry briefly.

For volume, lift a section, mist underneath at the roots and let it set before dropping the hair. That props up the roots without coating the outer layer with stiff product. A volumizing or thickening spray applied before blow-drying will do more for fullness than any finishing spray; our guide to hair thickening products covers those.

Finally, think about removal. On fine or fragile hair, the safest way to remove strong hair spray is to wash it out, or at least dampen the hair before detangling with a wide-tooth comb. Brushing through dry, stiff hair is one of the most common, and most avoidable, causes of styling breakage.

Hair spray is not harmful to hair when used sensibly. It does not cause hair loss, and its alcohol evaporates within seconds. The problems people blame on hair spray usually come from how it is used: heavy layers that are brushed out dry, daily strong-hold use on fragile hair, and buildup that never gets fully washed out.

Buildup affects both hair and scalp. Polymer film that accumulates on the lengths makes hair dull, stiff and harder to style. On the scalp, layers of spray combined with oil and dead skin can leave it feeling itchy or flaky. A clarifying shampoo every week or two, or whenever hair feels coated, removes it and gives you a clean starting point.

Avoid spraying directly onto the scalp. Aim at the hair, and if you are lifting roots, spray the underside of the section rather than the skin. If you have a sensitive scalp, eczema or seborrheic dermatitis, a fragrance-free or unscented spray may be better tolerated.

Heat and hair spray do not mix well. Spraying before using a curling iron or flat iron can make hair crunchy, and spray that has not dried is flammable. Use a heat protectant before heat tools and save hair spray for the finish, after the hair has cooled.

Finish styling first, and let hair cool. Hot hair is still soft and shapeable; spraying it locks in a style before it has set. Once curls or a blowout have cooled, hold the can 10 to 12 inches away and sweep it across the hair in light, continuous passes rather than aiming at one spot.

Spray in layers. For more hold, lift sections and mist underneath, then smooth the top layer with a light final pass. To tame flyaways without stiffening the whole style, spray a little onto a clean toothbrush or your palm and smooth it over the stray hairs.

For updos, use a stronger spray as a working spray on each section before pinning. That adds grip and helps pins stay put, which means fewer pins and less tension on the hair. Finish with a light overall mist rather than a heavy coat.

At the end of the day, remove spray gently. Wash it out with shampoo, or dampen the hair before detangling with a wide-tooth comb, working from the ends up. Never rake a brush through stiff, heavily sprayed hair. A good routine makes hair spray part of a healthy hair routine rather than a source of breakage.
