For clients battling frizz, dryness, damage and unmanageable hair, the demand for healthier hair-smoothing solutions continues to grow. Enter HairB, RG Cosmetics' innovative formaldehyde-free straightening treatment system, often referred to as a "hair botox" treatment for its ability to rejuvenate, smooth and restore hair from the inside out.
