It replenishes by entering the deepest layers of hair strands to smooth, soften, and intensely hydrate hair while restoring elasticity.

How to Use

• Press firmly at the center of the diffuser.
• Apply one to two pumps on clean, towel-dried hair.
• Massage onto lengths and ends.
• Leave in.
• Blow-dry and style as desired.
• Can also be applied to dry hair after styling as a finishing touch to smooth flyaways and seal split ends.
• Complete routine with Kérastase’s full Resistance range for maximum strengthening benefits (sold separately).

Pro tip: Use just a touch on flyaways when the hair is staticky for added moisture and to create a smooth, sleek finish.
