By eliminating the build-up of debris, sebum, and scalp flakes that can obstruct hair follicles and inhibit hair growth, this profoundly cleansing shampoo improves scalp health and hair growth. The shampoo is particularly great for thin, fine hair because it adds body and volume after just one wash, leaving hair glossy and full. Hair can grow freely from the root when the scalp is clear of sebum, fatty acids, and environmental debris. It also helps nutrients get to your scalp and hair follicles more readily. The washing shampoo from Effica produces a thick foam in the shower and leaves the scalp feeling clean and fresh. For fine or thinning hair, the conditioner and scalp treatment from the same line work well together.
