Product Description
Keep your hair in tip top condition even when you use your favorite heat styling tools with the must-have Kérastase Genesis Defense Thermique Heat Protector.
This formula is an essential for any hair styling routine as it protects your locks from heat up to 220°C, whether you're using a hair dryer, curlers or straighteners. Better yet, it helps detangle your locks and prevents any future breakages from brushing or tricky knots. Plus, the heat protecting solution adds a boost of hydration to dry stands and shields against frizz and flyaways for up to 24 hours.
Crafted with a blend of ginger root, aquaxyl and edelweiss native cells, this product is part of the Kérastase Genesis range. These nourishing ingredients help prevent hair fall and strengthen already weakened tresses.
