How to apply the B24 Leave-in Hair Mask?Updated a year ago
After washing the hair with shampoo and without using conditioner, remove excess moisture with a towel. Apply a small amount of the B24 mask (1-4 times depending on hair length, density, and condition). Rub between palms to form a uniform white emulsion, then distribute evenly from roots to ends and leave on for 4 minutes. Do not rinse; style hair as usual.
