Kérastase Resistance Extentioniste Length Strengthening Mask (200ml) is a deep-conditioning, restorative mask which nourishes hair from lengths to ends, providing healthy-looking hair from lengths to tips.

Especially effective on fragile, damaged hair, it fortifies hair fibres by increasing electrostatic bonds, seals the cuticle and conditions the scalp. Formulated with Creatine R and Maleic Acid, it inhibits breakage and produces an even, glossy result.

Directions of use:

• Apply a hazelnut-sized amount to clean, towel-dried hair and distribute through lengths.
• Leave in for 5 minutes.
• Emulsify and rinse thoroughly.
