Finasteride For Male Pattern Baldness
Finasteride is a medication used to treat hair loss in men. It is primarily prescribed for male pattern baldness, also known as androgenetic alopecia. Male pattern baldness is a common condition characterized by a receding hairline and thinning of hair on the crown of the head.
Finasteride belongs to a class of drugs called 5-alpha-reductase inhibitors. It works by blocking the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT). DHT is the hormone responsible for shrinking hair follicles in individuals with male pattern baldness. By inhibiting the production of DHT, finasteride helps to prevent further hair loss and may even promote hair regrowth in some cases.
When taken orally as prescribed by a doctor, typically at a dose of 1 milligram per day, finasteride can effectively slow down or halt the progression of hair loss in men. However, it is important to note that the effects of finasteride on hair growth may take several months to become noticeable, and the medication needs to be taken continuously to maintain its benefits.
It is worth mentioning that finasteride is not approved for use in women, especially those who are pregnant or planning to become pregnant, as it can cause harm to a developing fetus. In addition, women should avoid handling crushed or broken finasteride tablets as the medication can be absorbed through the skin.
Finasteride for Male Pattern Baldness: How It Works
Finasteride for hair loss targets the hormone dihydrotestosterone (DHT), which plays a significant role in male pattern baldness. Here’s how it works:
1.
Conversion of Testosterone
Testosterone, a male hormone, is converted into DHT in the body with the help of the enzyme 5-alpha-reductase. DHT is more potent than testosterone and has a stronger impact on hair follicles.
2.
Miniaturization of Hair Follicles
In individuals genetically prone to hair loss, DHT binds to receptors in hair follicles, particularly those in the front, top, and crown of the scalp. This binding process leads to the miniaturization of hair follicles, resulting in thinner, shorter, and weaker hair strands over time.
3.
Inhibition of 5-alpha-reductase
Finasteride for hair loss inhibits the activity of the enzyme 5-alpha-reductase, reducing the conversion of testosterone to DHT. Doing so lowers the levels of DHT in the scalp and hair follicles.
4.
Protection of Hair Follicles
With reduced DHT levels, the hair follicles are no longer exposed to its damaging effects. This allows the hair follicles to recover, resulting in thicker, healthier hair growth.
5.
Hair Maintenance and Regrowth
By effectively blocking the formation of DHT and protecting the hair follicles, finasteride helps to slow down or halt the progression of hair loss. In many cases, it can also promote hair regrowth, leading to a fuller and denser head of hair.
What types of alopecia does finasteride treat?
A receding hairline and thinning of hair on the crown of the head characterize male pattern baldness. Finasteride for hair loss can help slow down or halt the progression of hair loss in men with this condition.
However, it’s important to note that finasteride is ineffective in treating other types of hair loss unrelated to the hormone dihydrotestosterone (DHT). These include:
1.
Alopecia areata
This is an autoimmune condition where the immune system mistakenly attacks the hair follicles, resulting in patchy hair loss on the scalp or other parts of the body. Finasteride is ineffective in treating this type of hair loss because it does not target the immune system.
2.
Telogen effluvium
This is a temporary form of hair loss that occurs due to factors such as stress, illness, hormonal changes, or medication. Finasteride is not designed to address the underlying causes of telogen effluvium, so it is not typically used for this condition.
3.
Traction alopecia
This type of hair loss is caused by excessive tension or pulling on the hair follicles, often due to tight hairstyles or hair treatments. Finasteride cannot reverse the damage caused by traction alopecia, as it primarily targets the hormone DHT.
4.
Other forms of hair loss
Finasteride for hair loss is specifically designed to target the effects of DHT on the hair follicles. If hair loss is caused by factors unrelated to DHT, such as nutritional deficiencies, scalp infections, or other medical conditions, finasteride may not be an effective treatment.
