Biotin DHT Blocker Shampoo - Hair Growth, Scalp Care & Dermatitis Treatment - Anti Dandruff, Thinning Solution - Itchy Scalp Relief - Men & Women - 473ml

Thicker, Fuller-Looking Hair Starts at the Scalp

Most shampoos clean the hair. This one works harder. The Ammuri Biotin DHT Blocker Shampoo is formulated to target the root cause of hair thinning — DHT-related follicle miniaturisation — while nourishing the scalp environment that healthy hair growth depends on.

Used consistently 3–4 times per week, customers typically notice a reduction in shedding within 3–4 weeks and visible improvements in thickness and volume within 8–12 weeks.

Key Ingredients

• Biotin (Vitamin B7) — Strengthens the hair shaft and supports keratin production, reducing breakage and improving overall hair resilience.
• Caffeine — Stimulates the scalp and helps counteract the effects of DHT on hair follicles, encouraging a healthier growth cycle.
• DHT-Blocking Complex — Targets dihydrotestosterone at the scalp to slow follicle miniaturisation, the primary driver of pattern hair thinning.
• Argan Oil — Rich in fatty acids and vitamin E; conditions the scalp, reduces inflammation, and adds shine without weighing hair down.
• Saw Palmetto Extract — A well-studied natural DHT inhibitor that supports a healthier scalp environment for sustained hair growth.

What Makes This Different

• Sulphate-free — gentle enough for daily use and colour-treated hair
• Cruelty-free formulation
• No harsh stripping agents — maintains scalp moisture balance
• Suitable for men and women experiencing thinning or shedding
• 473ml — a generous size that lasts 2–3 months with regular use

How to Use

1. Apply to wet hair and work into a lather from roots to ends.
2. Massage into the scalp for 2–3 minutes — this activates the DHT-blocking and caffeine complex.
3. Rinse thoroughly with warm water.
4. Follow with the Ammuri Hair Thinning Conditioner and Hair Growth Serum for best results.
5. Use 3–4 times per week. Daily use is safe for most hair types.
