If your hair is fine, thinning, and chemically treated, consider Nioxin System 4 Cleanser, a volumizing shampoo that removes fatty acids, sebum, and various environmental residues from the hair and scalp. Hair looks fuller and hair strands are thickened. Amino acids help reduce hair loss because hair become stronger and less likely to break or become damaged. Vitamins and botanicals help cleanse the scalp while sunscreen protects it. White tea extract, peppermint oil, humectants, and conditioning agents help moisturize color-treated hair while also rejuvenating the scalp. To use this shampoo, which can be used daily, apply it to wet hair and gently massage it into both hair and scalp. After lathering for a minute, rinse fully. The cleanser is part of a three-step treatment program intended to thicken color-treated hair that is progressively thinning. The moisture provided is in the medium or balanced range. While gently cleaning follicles that are likely clogged with sebum, the shampoo also offers lightweight conditioning.
