Hair conditioner is used as a final step during hair washing, after using shampoo and mask. It is typically applied to clean, wet hair, along the entire length, avoiding the scalp, and left to act for a few minutes before rinsing. Conditioner is often mixed with a hair mask, although these products have different purposes. The mask is intended for deep hydration and protein nourishment of the hair, while the conditioner works in a completely different way. The primary role of the conditioner is to smooth the hair by closing the hair cuticle. This reduces tangling and hair breakage, making it easier to comb. Therefore, conditioner is an essential part of regular hair care and its use is recommended during every hair wash.
