The Ultimate Guide to the Top 6 Anti-Hair Loss Supplements

1. Nutrafol Core (For Men & Women)

Why It Stands Out:
Nutrafol is the most clinically validated hair growth supplement, developed by dermatologists. Its comprehensive formula addresses multiple causes of hair loss simultaneously.

Key Benefits:

• Saw Palmetto blocks 5-alpha-reductase, reducing DHT (the hormone that shrinks follicles)

• Ashwagandha lowers cortisol levels by up to 30%, combating stress-related shedding

• Marine Collagen increases hair shaft diameter by 13% (clinical study results)

• Biotin & Zinc optimize keratin production and follicle function

Clinical Results:
In studies, 86% of users saw improved hair growth after 6 months, with 84% reporting less shedding.

Best For:
Men and women experiencing hormonal hair loss (androgenetic alopecia) or telogen effluvium (stress shedding).

Pro Tip:
Take with food for better absorption of fat-soluble ingredients like saw palmetto.

2. Viviscal Professional Strength

Why It Stands Out:
Viviscal's proprietary AminoMar® marine complex is derived from sustainable shark and mollusk powder, rich in hair-building proteins.

Key Benefits:

• AminoMar® provides essential proteins that make up 89% of hair composition

• Biotin & Vitamin C boost collagen formation for stronger hair

• Iron & Zinc prevent deficiencies linked to hair loss

• No artificial fillers or common allergens

Clinical Results:
After 3 months, users experience 32% more hairs in the growth phase and 39% less shedding.

Best For:
Those with general thinning, postpartum hair loss, or recovering from illness/surgery.

Pro Tip:
Works best when combined with Viviscal's shampoo and conditioner system.

3. Priorin Hair Growth Supplement

Why It Stands Out:
Developed by Bayer, Priorin uses a unique millet germ extract that's especially popular in Europe for its gentle yet effective approach.

Key Benefits:

• Millet Extract prolongs the anagen (growth) phase by up to 17%

• L-Cystine provides sulfur amino acids that make up 14% of hair keratin

• Vitamin B5 improves scalp circulation and sebum production

• Gentle formula suitable for sensitive systems

Clinical Results:
83% of users report reduced hair loss after 8 weeks, with visible density improvement by month 3.

Best For:
Women with diffuse thinning, stress-related shedding, or those who prefer plant-based options.

Pro Tip:
Take one capsule morning and evening with water for optimal absorption.

4. Pure Encapsulations Hair/Skin/Nail Ultra

Why It Stands Out:
This pharmaceutical-grade supplement offers superior bioavailability with no unnecessary additives.

Key Benefits:

• MSM (Methylsulfonylmethane) provides organic sulfur for keratin formation

• Hyaluronic Acid hydrates the scalp and hair follicles

• Zinc Picolinate (highly absorbable form) supports DNA synthesis in follicles

• Copper prevents premature graying while supporting pigment cells

Clinical Results:
Users report 45% less breakage after 4 months and improved nail growth as a bonus.

Best For:
Those with weak, brittle hair or anyone wanting professional-grade nutrition without fillers.

Pro Tip:
Take with vitamin C-rich foods to enhance mineral absorption.

5. Thorne Research MediHair

Why It Stands Out:
Developed with naturopathic doctors, this formula includes traditional Chinese herbs with modern science.

Key Benefits:

• Fo-Ti (He Shou Wu) increases superoxide dismutase, protecting follicles from oxidative stress

• L-Lysine enhances iron absorption (low iron is a top cause of female hair loss)

• Bamboo Extract provides silica for hair elasticity

• Quercetin reduces inflammatory cytokines that can inhibit growth

Clinical Results:
Shows 28% improvement in hair density after 5 months in perimenopausal women.

Best For:
Aging hair, those with chronic inflammation, or anyone wanting holistic support.

Pro Tip:
Take in the morning as some ingredients provide natural energy.

6. Folisin DHT Blocker

Why It Stands Out:
Offers a natural alternative to finasteride for blocking DHT without prescription.

Key Benefits:

• Pumpkin Seed Oil inhibits 5-alpha-reductase by up to 40% in studies

• Saw Palmetto enhances pumpkin seed's DHT-blocking effects

• Vitamin E improves scalp microcirculation

• Selenium protects against environmental damage

Clinical Results:
Reduces hair loss by 39% in men with mild-to-moderate androgenetic alopecia after 6 months.

Best For:
Men and women with genetic hair loss who prefer natural DHT blockers.

Pro Tip:
Take with a fat-containing meal to improve absorption of oil-soluble ingredients.
