A fortifying weekly mask for hair weakened by active hair loss
René Furterer Triphasic Active Grow Fortifying Anti-Breakage Mask is a fortifying mask made to follow the Triphasic Active Grow shampoo during a period of active, ongoing hair fall. It nourishes lengths and ends that often feel thinner and more brittle when the scalp is shedding more than usual, reinforcing the hair fiber so it resists breakage while new growth comes in.
The texture
A rich, creamy mask that melts into lengths and ends, detangles as it works, and rinses out without leaving hair heavy or greasy.
Who it suits
- Hair weakened by a recent, active hair loss episode
- Lengths that feel thin, dry or prone to breakage
- A weekly step alongside the Triphasic Active Grow shampoo
- All hair types, including color-treated hair
Worth knowing before you buy: this mask fortifies and softens the hair fiber; it is a cosmetic care, not a treatment for the underlying cause of hair loss.
How long one jar lasts
Used once a week, a 200ml jar lasts around four to five months for one person.
