Fine, fragile hair is particularly vulnerable to all kinds of injuries, including thermal damage from hot styling tools: dryer, curler or flat-iron. On the one hand, we must shield it from extreme temps. On the other hand, it needs nourishment without weighing down. Which products are best for this purpose? Read our round-up of top heat protectants for fine, delicate hair.

Fine hair is tricky to deal with. Every layer of a hair product you apply makes it fall flat, lose volume and look unfresh. On the other hand, deep cleansing or aggressive in-salon procedures like bleaching don’t make it any better either. Fine hair is naturally more prone to damage from improper hair care products or breakage while you try to detangle wet strands, for example. Any careless action worsens the hair, making it dry and limp fast, leading to split ends and brittleness.

Styling the hair with assistance of hot tools – for example a hairdryer, straightener or curler – is one of the most destructive things. Providing the locks with sufficient anti-heat protection is a must, however, it must be done with a product which won’t leave them heavy, greasy or sticky. Otherwise, the created style – silky smooth hair or a head of bouncy curls – will last literally for a moment. How to choose the best heat protectant for fine hair? Read our ranking.

#2 Montibello Decode Smooth Perfection – protective & smoothing spray

A spray from a well-known brand comes second. Even though it serves its purpose, protecting the hair from thermal damage, we believe it costs too much, especially when we read reviews saying it doesn’t last long. Montibello Decode Smooth Perfection Spray is made for thin, fragile hair and girls who like to wear it straight. The product smooths the hair, controls frizz, adds shine, softens and fixes split ends, plus makes the hair more resistant to humidity. It can be used either on wet or dry hair.

#3 Alterna Caviar Restructuring Bond Repair – protective and repairing styling mousse for damaged hair

The combo of repairing and nourishing properties in the Alterna Caviar Restructuring Bond Repair Mousse makes it a great choice for damaged, brittle, problematic hair, also thin and extremely fragile. The product is used on wet hair before blow-drying – it will protect from thermal damage, plus strengthen the hair, smoothen its external layer, nourish and revitalize it. The product contains extracts from apples, caviar, rice bran, sunflower and rosemary. It delivers protection from 232 degrees Celsius. If you like styling mousses and know how to use them – it’s worth a shot!

#4 Davines Liquid Spell – reinforcing and bodifying fluid for fine hair

This fluid, which turns into a light mousse before use, is made specially for styling and nourishing fine, fragile hair. The manufacturer advises applying it onto wet hair before blow-drying for anti-heat protection. Healthier, thicker, reinforced, softer and more shiny hair is the result. Davines Liquid Spell Fluid seals the cuticle layer, thickens the hair, and protects it from external aggressors. It makes the locks stay smooth, glossy and free from frizz or tangling. It boosts volume too. We’re just wondering if the price is fair for such a small bottle…

#5 Kemon Hair Manya Memory Thermo Protection – spray for protection against thermal damage

Kemon Hair Manya Memory Thermo Protection Spray is the last one in our ranking. It isn’t made specifically for thin hair, but it does serve its purpose – thanks to the so-called memory-effect protection, the product will keep the hair safe even after the styling routine and there’s no need for re-application. If you don’t mind the intense aroma, then it’s a perfect choice.
