My Boostars Collagen Series is a premium Japanese haircare set featuring a shampoo, treatment, and a unique two-layer booster mist. The system contains three types of micro-collagen, biotin, and plant extracts designed to deeply moisturize hair and scalp. The signature feature is its "skin-care inspired" approach, requiring a brief waiting period between mist and treatment application. Best suited for those with dry, unmanageable hair seeking moisture and smoothness. The products feature a pleasant bergamot aroma and are sulfate-free, making them gentle enough for daily use.
