Overview
Bathroom routines for people growing out their hair get a five minute mask that treats scalp, lengths and ends. Biotin, niacinamide and castor oil nourish while it reduces breakage and frizz.
Treating the scalp as well as the ends sets it apart from masks that only coat lengths. The headline strength result comes from using it with the Extreme Length shampoo.
Who it's for
Anyone growing hair longer and losing length to breakage gets a fast weekly treatment. Those with extremely dry hair may want a richer mask as well.

Performance notes
Biotin, niacinamide and castor oil work on the scalp and lengths, while conditioning agents smooth the ends. Breakage drops as friction falls during combing. Visible length gains depend on steady use over time.
