It is a physician-formulated product that stands out in the crowded supplement market for its scientific backing and dermatologist recommendation.
The key to Nutrafol's effectiveness lies in its proprietary blend of 22 ingredients, such as Ashwagandha, Saw Palmetto, and Curcumin. In a clinical study, 100% of women reported improved hair strength after 3 months and more scalp coverage after 6 months. This real-world performance data gives users confidence that the supplement can genuinely help reduce shedding and promote thicker hair over time.

Buying Guide: Key Ingredients to Look For
Biotin and Keratin
Biotin is a B vitamin that helps your body produce keratin, the protein that makes up your hair. Without enough biotin, strands can become brittle and prone to breakage. Many top supplements include biotin at doses around 5,000 mcg for daily support.
Keratin itself is often added in hydrolyzed form, which means it is broken down for easier absorption. Combining biotin with keratin can strengthen the hair shaft from the inside. For more on specific formulas, see our article on best selenium for hair health.
Saw Palmetto and Pumpkin Seed Oil
Saw palmetto is a plant extract traditionally used to support scalp health. It may help reduce the effects of certain hormones on hair follicles, making it a popular ingredient in hair supplements for both men and women.
Pumpkin seed oil is rich in omega fatty acids and phytosterols. When paired with saw palmetto, it offers a dual-action approach to maintaining hair density. Learn more in our guide to the best pumpkin seed oil supplement for hair.
Collagen and Amino Acids
Collagen provides the building blocks for strong hair, skin, and nails. Hydrolyzed collagen peptides are often included in hair supplements because they are easily absorbed and support the structure of the hair follicle.
Amino acids like L-cysteine, L-lysine, and L-methionine also contribute to keratin production. These ingredients work together to improve strand resilience and reduce shedding. For more insights, explore our COMPARISONS page for side-by-side evaluations.
Adaptogens and Stress Support
Stress is a common trigger for hair thinning. Adaptogens like ashwagandha, reishi mushroom, and shatavari root help your body manage stress responses. Including these in a hair supplement addresses one of the root causes of shedding.
Many premium formulas now combine adaptogens with traditional hair nutrients. If you are looking for a comprehensive approach, products with both botanical extracts and vitamins may suit you well. Check out our review of best iron supplements for hair support for additional tips.
