Nioxin System 4 Scalp + Hair Shampoo 1L is a daily cleansing shampoo developed for dry, damaged, color-treated hair with advanced thinning.
Nioxin System 4 Scalp + Hair Shampoo 1L is a shampoo for dry, damaged, and color-treated hair with advanced thinning. It cleanses the scalp and hair gently, while helping create the right conditions for thicker-looking strands. Because thinning hair often needs targeted care, this shampoo focuses on both scalp health and fiber strength. First, the formula removes impurities, excess sebum, and product buildup from the scalp. As a result, follicles remain clearer and better balanced. Furthermore, this gentle cleansing action supports a healthier scalp environment without weighing the hair down. Meanwhile, color-treated hair benefits from a careful approach that respects fragile fibers. In addition, the shampoo helps reduce hair weakening linked to breakage. Over time, hair appears fuller and more resilient. In fact, the formula was clinically developed to improve the look of thickness and volume in just 30 days, when used consistently as part of the system.
The formula includes a blend of essential oils and active ingredients selected for scalp care. For example, Mentha arvensis essential oil provides a refreshing sensation that helps stimulate the scalp. Peppermint essential oil, however, supports the regulation of excess oil, which is important for maintaining balance. Salicylic acid, in addition, helps remove dead skin cells and residue, so the scalp feels cleaner and more comfortable. Because of its targeted yet gentle approach, it fits well into a routine for advanced thinning hair. Used regularly, it supports scalp clarity and improved hair structure, resulting in hair that looks denser and healthier over time.
Apply Nioxin System 4 Scalp + Hair Shampoo 1L to damp hair and massage the product onto the scalp. Then, fully rinse to remove the product.
