Mereltä Root Renewal Serum is a revolutionary microalgae-based scalp treatment designed to protect and nourish the scalp. Aging of the hair, just like aging of the skin, is due to stress triggered by pollutants, chemicals, disease, and other culprits that harm the scalp. These stressors damage the hair inside the follicle before its emergence from the scalp, causing hair loss and premature baldness. Mereltä’s tiny, special microalgae in the Root Renewal Serum come to the rescue as they nurture the scalp, balancing, nourishing, and protecting it, while strengthening the hair to promote healthier and thicker strands, and give you a great look.
