Better Roots RootBoost Serum is a fast absorbing, oil-free, groundbreaking scalp serum for hair longevity. The serum nourishes hair follicles and scalp skin cells in support of healthy hair regrowth for the appearance of thicker, fuller hair and a hydrated, soothed scalp, while also promoting melanin synthesis for preventing or delaying the onset of gray hair. Weightless and non-greasy, this serum absorbs instantly into the scalp, making it an ideal choice for those with fine hair. 

Twelve clean clinically proven active ingredients work synergistically to stimulate hair follicles and surrounding skin cells in support of protein and melanin synthesis, which are the processes inside hair follicles that control hair growth and hair color. The serum also helps maintain the scalp's microbiome, reduces inflammation, and repairs cellular damage from UV exposure and other environmental factors. 

A $144 value for only $99.
