A heat protectant is basically the one product you should always apply before styling with heat, it forms a protective layer around your hair strand. Products with a lot of alcohol, or wax and pomade with a low melting point, are better avoided right before you style, since they can dry out your hair or stick to a hot barrel. Oil and shine products are usually applied after styling, not before.
Quick summary
- Heat protectant belongs before nearly every session with an airstyler, blow-dryer, or straightener.
- Products high in alcohol can dry your hair out further if you use them right before styling.
- Wax, pomade, or other products with a low melting point can stick to a hot barrel.
- Oil and shine serums usually work better after styling than before.
- Too much product at once causes buildup, which makes your styling result flatter and less sleek.
Below, you'll see what each product type does, and whether it belongs before, after, or ideally not right before heat styling at all.
Which product basically always belongs before styling with heat?
Heat protectant. This product lays down a thin layer around your hair strand that helps limit moisture loss while heating, and gives the hair shaft a bit more protection against the direct heat of your airstyler, blow-dryer, or straightener.
Apply it to towel-dried or dry hair, spread it evenly from mid-lengths to ends, and let it soak in for a moment before you start styling.
Which ingredients are better avoided right before heat styling?
Products high in alcohol (often listed as "alcohol denat" near the top of the ingredient list) evaporate quickly and can dry your hair out further if you apply heat shortly after. That's especially worth watching for on colored or chemically treated hair, which is already more prone to drying out.
Wax, pomade, or styling creams with a low melting point aren't a great idea right before styling either. They can melt on the hot barrel or plate, leaving residue on both your hair and the device itself.
Can you use hair oil before or during styling with an airstyler?
Oil is usually better applied after styling, on the lengths and ends, for shine and to tame frizz. Some oils tend to smoke or burn at high temperatures, and you don't want that happening close to your hair and the barrel.
If you still want a product with oil in it before styling, choose specifically a heat protectant that has oil built in and states on the packaging that it's suitable for use before heat styling. Plain oils from your kitchen cupboard or unrefined plant oils aren't made for that.
What does product buildup do to your styling result and your airstyler?
If you layer several products, like mousse, serum, and heat protectant all at once, there can be more product on your hair than it can absorb. That excess settles onto your hair strand and can also leave a thin residue on the barrel or plate of your styling tool.
An even, clean surface gives you more even heat transfer. That's why it's smart to clean your barrel regularly and not use every product at once every single time.
Overview: which product goes when?
| Product type | Before or after heat styling? | Why |
|---|---|---|
| Heat protectant | Before | Protects the hair shaft against moisture loss from heat |
| Volumizing mousse | Before | Works together with the heat to hold shape and volume |
| Product high in alcohol | Better not right before | Can dry out the hair shaft further when combined with heat |
| Wax or pomade | After | Can melt and leave residue on a hot barrel |
| Hair oil or shine serum | After | For shine and against frizz, without the risk of burning during styling |
Frequently asked questions
Do I really need heat protectant if I use an airstyler on a low temperature?
Even at lower temperatures, heat still stresses your hair, so heat protectant is still worth using. At a lower temperature you can get away with a little less product than at high temperatures.
Can I use dry shampoo right before heat styling?
Yes, dry shampoo is usually not a problem, as long as you brush it out properly so no white residue or clumps are left in your hair near the barrel or plate.
Can the wrong product damage my barrel?
Products that melt or burn on a hot surface, like wax with a low melting point, can leave residue that builds up. Cleaning your barrel regularly stops that residue from accumulating.
How much product should I use roughly before styling?
That varies by hair length and thickness, but start small, for example a coin-sized amount of heat protectant, and add more only if you find it isn't enough. Too much product at once builds up faster than too little.
An evenly heated surface is the difference between good styling and burnt-on product residue.
The Airstyler Pro Ceramiq has a fully ceramic-coated barrel that spreads heat evenly, instead of hotspots that bake products onto the surface faster. That means it works well together with the right heat protectant, on every hair type from 1A to 4C.
