Sai Zen advanced hair products are an effective way to clean your scalp, increase hair metabolism, and clear away any dirt clogged in pores using natural essences and herbs. Natural herbs will further enhance, heal and clean your scalp to encourage hair thickening. Active ingredients work to inhibit the production of DHT and restructure damaged hair root nerves and activate those hair cells, thereby returning the hair to its normal cycle. The strong formula / ingredients help to produce cells that make up hair and boost blood flow to the fine capillaries of the scalp, which then brings more oxygen and nutrients to the scalp and leads to hair repair and hair thickening.
