What Are Dihydrotestosterone Blockers?

Do you wonder what dihydrotestosterone blockers are? These are also known as DHT blockers, as dihydrotestosterone is often abbreviated as DHT. DHT blockers are essentially drugs that prohibit the formation of DHT. A side of effect of DHT that many suffer is hair loss. This is a result of blood supply to hair follicles being restricted. The common result of this is that follicles over time die off and then fall out.

The human body has a natural process that turns testosterone into DHT, so DHT blockers should prevent the process from occurring. Adult males who use a DHT blocker often see their hair loss slow, and many cases even witness new hair growth occurring. There are two DHT blockers that are far more common than all others. These two are finasteride and dutasteride.

Finasteride is a scientific name, so looking for it on retail shelves near you might not prove a fruitful use of your time. Rather, look for one of its brand names. The most common is Propecia, and your doctor can certainly go over your options with you. This drug has Food and Drug Administration approval for the intended treatment of hair loss that is a result of generic male pattern baldness.

Are DHT Blockers Effective?

Propecia functions by stopping the activities of a certain enzyme, known as 5-alpha-reductase. This enzyme has been seen at prevalent levels in bloodstreams of men who are afflicted with hair loss. When 5-alpha-reductase’s activities are inhibited, finasteride can effectively proactively stop DHT from ever forming, and that helps minimize hair loss from happening.

The other common DHT blocker of dutasteride is widely available through the market brand name of Avodart. It functions very similar to Propecia, as it blocks 5-alpha-reductase enzymes. That enzyme comes in Type I and Type II, though, and while Propecia inhibits Type I, dutasteride as Avodart blocks both Types I and II. Expected DHT formation reduction is measured at up to 90 percent after just 14 days. That makes dutasteride far more potent than finasteride for treating hair loss.

Other DHT blockers do exist and are available through retail channels, but a consultation with your physician is always a good idea, considering he or she can give you access to prescription options as well. Your doctor or primary care physician is also a possibility in terms of getting a referral to a dermatologist who can best assist you.
