The ULTRAfiller Hair Density Scalp Serum is a lightweight, non-greasy solution for thin, fine hair. Powered with active ingredients like biotin, known to provide hair with strength; peptides, known to have anti-inflammatory properties that optimize hair follicle activity; and caffeine, known to energize roots, this scalp serum creates the optimal environment for thicker, fuller hair. This scalp serum balances and revitalizes the scalp to promote a healthy scalp environment and boosts hair and root health. Less breakage leads to reduced hair shedding and increased hair density. It is also formulated with Rosemary essence to enhance relaxation and well-being.
