Developed especially for children, it prevents hair from frizz, marks and knots. As it is a fabric with smooth and soft fibers, satin, in contact with the hair, reduces friction, in addition to not absorbing the natural oils of the hair, avoiding the appearance of dryness. The Bio Extratus Satin Cap is made on double sides and has a regulating tip for greater comfort and adaptation to the size and/or volume of hair. Cap Measure M: 43cm in diameter. Cap measurement L: 53cm in diameter.
