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.

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

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

5. Thorne Research MediHair

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.

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

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.
