1. DHT Hair Loss: A Chemical Process
DHT hair loss begins with testosterone. The trouble starts once testosterone combines with an enzyme present in the oil glands found in hair follicles. Genetics determine how much of the enzyme 5 alpha reductase a person creates. This turns the hormone into dihydrotestosterone, or DHT. Once DHT penetrates the scalp follicles, they shrink and die. The result is hair loss, otherwise known as androgenetic alopecia.
2. Miracle Hair Care Products for Baldness?
Block the enzyme production that is present in the oil glands, and the DHT production is blocked. That makes sense, but is it possible? Many hair care products contain ingredients such as zinc, saw palmetto and gingko biloba, which are supposed to stop the enzyme production. This should result in the thinning of the protective membrane of the scalp that thickens due to DHT. As the hair follicles come back to life, the hair can grow again. The problem with these claims is that the Federal Drug Administration (FDA) doesn't test the ingredients mentioned above for effectiveness because they aren't classified as drugs.
3. FDA Approved Propecia for DHT Hair Loss
The FDA has tested the prescription drug Propecia, or finasteride. This drug works by reducing the production of the enzyme 5 alpha reductase, thereby reducing DHT levels. Only males can use this drug. Tests revealed that 66 percent of men grew hair on the back of the head, and 42 percent did so in the front. The majority of the rest of the men in the test did not experience any further hair loss.
4. FDA Approved Rogaine
Rogaine, also known as minoxidil, does not require a prescription in the U.S. Males can get a higher strength, but females can also use this drug. Men have success with hair growth in the back, but the drug works effectively in the front and back for women. Rogaine works differently than Propecia. DHT shrinks the hair follicles, but Rogaine swells part of the follicle's structure, which keeps the follicle open.
5. Making Sense of Claims for DHT Hair Loss
You can contact companies and ask for the product test information or medical journal references. If the company doesn't have either, pass on the product. If they do have information to back up the claims, read it. You can also ask your doctor. Remember, if it sounds too good to be true, it probably is.
