DHT can cause hair loss by shrinking hair follicles and shortening their growth phase. DHT blockers, such as prescription medicines, supplements, and natural foods, can prevent DHT production and binding.
Finasteride
Finasteride, available as Propecia, is an oral DHT blocker that can slow, stop, and reverse hair loss caused by male pattern baldness. It works by preventing the conversion of testosterone into DHT, increasing hair follicle count, and promoting new hair growth.
Other DHT Blockers
Natural supplements and shampoos can inhibit the production of the 5-alpha reductase enzyme, curbing DHT production on the scalp. When used with saw palmetto or biotin, these blockers can be effective. DrFormulas HairOmega Foam is an example of a product containing natural DHT blockers.
Minoxidil
Minoxidil is available without a prescription and works by widening blood vessels in the scalp, potentially reactivating dormant hair follicles. While it may not directly block DHT, it has successfully stimulated hair follicle growth. Some minoxidil products contain scalp-supportive ingredients like jojoba oil and tea tree oil.
DHT-Blocking Shampoos
DHT can cause hair loss in women experiencing hormonal fluctuations during menopause. DHT-blocking shampoos can help restore density and thickness over time. A shampoo containing ingredients like jojoba and coconut oils has successfully provided relief.
Pumpkin Seed Oil
Pumpkin seed oil is a natural DHT blocker containing essential fatty acids, zinc, magnesium, and phytosterols. It effectively lowers DHT levels and can be combined with other hair loss treatments like minoxidil. It may also promote hair growth by stimulating the scalp. High-quality supplements should be chosen.
Foods That Act as DHT Blockers
Saw palmetto extract, beta-sitosterol, and caffeine claim to act as natural DHT blockers, but research is limited. Zinc, found in foods like spinach, kale, pumpkin seeds, and meat, inhibits 5-alpha reductase activity. Coconut oil and lycopene in tomatoes and watermelons also have DHT-blocking properties and support hair health.
