Why heat protection is essential – advice from PRO HAAR specialists
Daily styling, blow-drying, or curling has become routine for many clients. But what they often don't realize is that heat is the biggest cause of hair aging and structural damage .
PRO HAIR specialists explain why heat protection isn't a luxury, but an absolute necessity for healthy, shiny, and resilient hair.
1. What heat does to the hair structure
The hair consists of keratin chains and disulfide bridges that together determine its strength and shape.
✔ Internal moisture evaporates from 150°C .
✔ At 180°C bonds begin to break .
✔ Above 200°C keratin denatures – irreversible damage.
The result: dry, porous, brittle hair that loses its shine.
2. Why Regular Serums Aren't Enough
Not every gloss or oil product is a true heat protectant.
✔ Many serums contain only silicones that do not distribute heat, but rather “bake” it in.
✔ A real heat protector contains polymers, amino acids or protein complexes that form a heat-resistant layer.
✔ This film does not evaporate, but absorbs and distributes the heat evenly.
Expert advice: choose sprays or creams with thermo-reactive polymers, panthenol, or hydrolyzed protein – they activate with temperature.
3. Difference between dry and wet heat
✔ Dry heat – straightening iron, curling iron, hot air brush.
✔ Wet heat – blow-dry on damp hair.
When hair is wet, the water literally boils in the cortex – this is called the bubble hair effect .
Solution: Pat hair dry first with a towel or microfiber cloth, blow-dry on medium setting, and use protector before drying .
4. The correct application of heat protection
Most mistakes are not caused by the product, but by misuse .
✔ Apply 2–3 pumps or 5–10 sprays to damp hair.
✔ Distribute evenly from mid-lengths to ends.
✔ Only blow-dry afterwards – never style immediately after application.
✔ Repeat lightly with every styling session.
PRO HAIR tip: For thick or unruly hair, use a cream protector + spray finish for maximum coverage.
5. Combination with professional treatments
✔ After Nanoplastia, Keratin or Hair Botox, heat protection is essential to prolong the effect.
✔ Protective polymers close the cuticle, so that amino acids and proteins are not lost.
✔ This keeps the hair smooth and shiny for up to 10 weeks longer.
Expert advice: never use a straightening iron above 180°C on chemically treated hair, even with protection.
6. Extra protection against sun and pollution
UV and air pollution aggravate heat damage.
✔ Choose products with UV filter + antioxidants (vitamin E, green tea) .
✔ Use a light leave-in spray on days with lots of sun or styling.
✔ Treat her with hydrating masks 1–2x per week.
Conclusion: protection is maintenance, not an option
Heat protection is the difference between shine that lasts and shine that burns off.
Professionals know that beauty starts with prevention – because every healthy hair starts with knowledge, not repair.
At PRO HAAR we say: Protect first, style later.
