How to use
How to Use:
Start with clean, towel-dried hair. Take 2–4 pumps of Kérastase Genesis Defense Thermique, adjusting the amount to suit your hair length and thickness. Work the product evenly through mid-lengths and ends, then comb through to distribute. Blow-dry or heat style as desired. On dry hair, smooth a small amount over lengths and ends to tame frizz and add shine.

Frequency:
Use as needed whenever blow-drying or heat styling the hair, or according to the product instructions.

Application Technique:
Apply mainly to the lengths and ends, avoiding the roots to keep volume. Use hands to smooth the fluid through the hair, then comb for even coverage before styling with a hairdryer or heated tools.

Best Practices:
For best cosmetic results, apply to freshly washed hair and focus on the most fragile areas. Allow the product to coat the hair evenly before using heat tools. Can be combined with other Genesis care products as part of a complete routine.

Safety Tips:
For external use only. Avoid contact with eyes; if contact occurs, rinse thoroughly with water. Discontinue use if irritation occurs and keep out of reach of children. Always follow any additional directions on the packaging.
