What Is DHT? Understanding the Hormone Behind Hair Loss
Learn how dihydrotestosterone (DHT) affects hair follicles, why it drives pattern baldness, and which options can help manage it.
What exactly is DHT?
Dihydrotestosterone (DHT) is a natural androgen hormone created from testosterone. It’s important for normal development, but elevated DHT at the scalp is closely linked to androgenetic alopecia (pattern hair loss) in men and can affect women too. When DHT binds to androgen receptors on susceptible follicles, it can start a process called miniaturisation—hair shafts grow thinner until the follicle may stop producing visible hair.
How DHT is produced
The enzyme 5α-reductase converts testosterone into DHT. This happens primarily in the prostate, testes, hair follicles, and adrenal glands. Once formed, DHT circulates and can bind to receptors in various tissues—including the scalp.
How DHT contributes to hair loss
- Shortens the growth (anagen) phase so hairs don’t grow as long or thick.
- Miniaturises follicles, producing progressively finer strands.
- Reduces effective nutrient delivery to the follicle over time.
Not everyone’s follicles are sensitive to DHT. In people with a genetic predisposition, thinning typically appears at the temples and/or crown and progresses gradually.
Common options for managing DHT
1) Finasteride (Propecia)
An FDA-approved oral medication that inhibits 5α-reductase to reduce DHT. It can slow loss and, for some, promote regrowth. Possible side effects: headaches, dizziness, erectile dysfunction, reduced libido, rashes, and mood changes. Always consult a healthcare professional.
2) Nutritional & botanical support
Some people prefer non-medical support to complement their regimen. Common inclusions: saw palmetto, pumpkin seed oil, stinging nettle root, beta-sitosterol, and zinc. Evidence varies—consistency and overall hair health routines matter.
3) HR23+ Hair Restoration Supplement
HR23+ Hair Restoration Tablets combine DHT-targeting botanicals with hair-health nutrients to support stronger, fuller-looking hair. HR23+ is not a cure for male or female pattern baldness, but may help reduce the impact of DHT on susceptible follicles.
