GRO Advanced Hair Serum for Severe Signs of Thinning

A dermatologist co-developed hair serum that visibly improves hair density, addresses shedding, and hydrates the scalp to support the skin barrier.

Hair texture: straight, wavy, curly, and coily. Hair type: fine, medium, and thick. Hair concerns: thinning and flaky, dry scalp.

Formulated for those with severe shedding, it is powered by a patent-pending, plant-based complex featuring an AI-selected blend of antioxidant-rich rhapontic rhubarb root and Japanese beautyberry extract that work synergistically to visibly improve hair density. Spanish microalgae, a prebiotic superfood, hydrates to rebalance the scalp environment, and plant stem cells anchor hair follicles from the root. In a 120-day clinical study of 40 participants using the serum once daily, 93% had a clinically measured increase in hair density, with up to an 87% reduction in hair loss due to breakage from washing and combing; in a 120-day consumer study, 98% saw less shedding. Formulated without fragrance. Vegan, gluten-free, and cruelty-free.

How to use: Apply a dropperful to the scalp daily and massage in. Use on wet or dry hair. Do not rinse.
