DHT and Hair Loss: What It Is and How to Address It
DHT and Hair Loss: What It Is and How to Address It
DHT — dihydrotestosterone — is one of the most common underlying causes of hair thinning and hair loss in both men and women. Understanding how DHT affects the hair follicle is the first step to addressing it effectively.
What Is DHT?
DHT is a hormone derived from testosterone through the action of an enzyme called 5-alpha reductase. It is present in both men and women, though typically at higher levels in men. DHT plays a role in the development of male characteristics, but it also has a significant effect on hair follicles in those who are genetically sensitive to it.
How DHT Causes Hair Loss
In people with DHT sensitivity, DHT binds to receptors in the hair follicle and causes it to miniaturise over time. This means the follicle produces progressively finer, shorter hairs until it eventually stops producing hair altogether. This process is known as androgenetic alopecia — or pattern hair loss.
The pattern of hair loss differs between men and women:
- Men — typically experience a receding hairline and thinning at the crown
- Women — typically experience diffuse thinning across the top of the scalp, with the hairline usually remaining intact
How to Address DHT-Related Hair Loss

Scalp Support
A healthy scalp environment supports follicle health. Ammuri’s Organic Aloe Vera Gel can be applied to the scalp to soothe, hydrate and support a healthy environment for hair growth.
What to Expect
DHT-related hair loss is a gradual process, and addressing it takes time. Most people need to use DHT-blocking products consistently for 8–12 weeks before noticing a visible difference. Early intervention tends to produce better results — the sooner you address DHT sensitivity, the more follicles you can support.

Frequently Asked Questions
Can DHT hair loss be reversed?
In the early stages, DHT-related hair thinning can often be slowed or partially reversed with consistent use of DHT-blocking treatments. Once a follicle has fully miniaturised and stopped producing hair, reversal is more difficult. Early intervention is key.
Does DHT affect women?
Yes — women also produce DHT, and DHT sensitivity can cause hair thinning in women, particularly after menopause when oestrogen levels decline. The pattern of thinning in women is typically more diffuse than in men.
How do I know if my hair loss is DHT-related?
DHT-related hair loss typically follows a predictable pattern — receding hairline and crown thinning in men, diffuse thinning across the top of the scalp in women. A dermatologist or trichologist can confirm the cause of your hair loss.
How long does it take for DHT blockers to work?
Most people need to use DHT-blocking products consistently for 8–12 weeks before noticing a visible difference. Results vary between individuals.
Is DHT blocker shampoo safe for daily use?
Yes — Ammuri’s Biotin DHT Blocker Shampoo is formulated for daily use and is suitable for all hair types.
