About this product
Philip B Scalp Booster is a 2 oz pre-wash treatment formulated to support healthier-looking hair and improve the appearance of fullness and density. Designed for thinning and fine hair, it uses a self-heating formula with Redensyl® and salicylic acid to stimulate scalp vitality, reduce shedding during washing, and enhance volume. The product is applied to dry, unwashed hair before shampooing, massaged into the scalp, and left for 5–20 minutes. It contains citrus extracts and exfoliating agents to help break down buildup on the scalp while avoiding phthalates, parabens, and sulfates.
