Nutrafol is the #1 Dermatologist-recommended hair growth supplement brand and is clinically tested to improve hair growth. Unlike other supplements, Nutrafol understands hair growth is not one-size-fits-all. All of Nutrafol’s Hair Growth Nutraceuticals are physician-formulated with over 20 ingredients at their effective serving size to address the bio-specific root causes of hair thinning for men and women through different life stages and lifestyles. While biotin and collagen are components of hair, skin, and nails, biotin and collagen supplementation alone have not been shown to be effective in promoting hair growth.
