Boosts hair density of new hair strands by 15%*. This lightweight, fast-absorbing scalp serum is expertly formulated for daily use to help improve visible hair fullness. The serum strengthens weakened hair from the roots and reduces hair fall due to breakage (or shedding) over time. Leaving the scalp feeling reinvigorated and moisturized, hair's dexterity will improve, appear visibly thicker, and feel stronger from the roots.
