What are the benefits of this hair mask?

Masque Reconstituant Hair Mask intensely nourishes, detangles and reinforces the hair to reduce the risk of hair fall due to breakage from brushing. It restores intense softness for beautiful healthy-looking hair.

How should I use this mask?

Apply to shampooed, towel-dried hair. Massage the lengths and ends. Leave on for 5 minutes. Rinse thoroughly.

Should I use Masque Reconstituant Hair Mask instead of Fondant Renforcateur Conditioner?

We recommend using Masque Reconstituant Hair Mask instead of the Fondant Renforcateur Conditioner as often as needed. Use the Masque Reconstituant Hair Mask after shampooing (in place of a conditioner) weekly or as needed.

Can Masque Reconstituant Hair Mask be applied on the scalp?

Masque Reconstituant Hair Mask is meant to take care of lengths and ends. It provides hair with intense moisture and reinforcement to fight against hair fall due to repeated processing like brushing. We do not recommend applying on the scalp.

What is the difference between hair-fall and hair-loss?

Hair-loss is defined by > 100 strands falling from the roots per day due to the hardening of collagen hair shaft. Hair-fall is defined by > 100 strands per day falling from the roots due to biological reasons (stress, hormones, diet) OR breakage.
