Of the many causative factors for frontal hair loss such as aging, genetics, medical conditions, and medication, the most common cause of frontal hair loss is androgenetic alopecia. Commonly referred to as male pattern baldness, androgenetic alopecia causes an identifiable, horseshoe shaped, frontal hair loss pattern in men.
This pattern ensues in people whose hair follicles are genetically sensitive to the hormone, dihydrotestosterone (DHT). Formed as a derivative when testosterone interacts with the enzyme 5-alpha-reductase, DHT disrupts the normal hair growth cycle by shrinking hair follicles (miniaturization) and eventually causes them to disappear.
According to the American Hair Loss Association (AHLA), hair loss occurs after hair follicles are subjected to DHT over an extended time period. However, with proper intervention, this process can be slowed down, stopped, and new hair can grow. Understanding the causative factors of hair loss is important in planning how to reverse frontal baldness in men.
Consulting a dermatologist helps determine the causes of frontal hair loss by assessing your overall health, examining the hair and scalp, and carrying out a blood test and a biopsy if necessary. In instances of hair loss caused by a medical condition, such as an under productive thyroid gland, treating the underlying condition often remedies the problem in short order.
Some clinical drugs used to treat arthritis and heart conditions are also known to cause hair loss. Switching medications under the guidance of your physician can help stop the hair loss process and can allow your hair to regrow.
Despite a myriad of hair loss products on the market, there are only two drugs approved by the FDA to reverse hair loss.
An over the counter drug, Minoxidil is a topical treatment available from most drugstores that you can use to prevent further hair loss and help stimulate hair growth. This treatment liquid should be applied twice daily to the scalp and the 2% solution is FDA approved for use by both men and women. According to the Mayo Clinic, it may take up to 12 weeks of daily topical application before new hair starts to grow.
By inhibiting 5-alpha-reductase, the enzyme that converts testosterone into DHT, Finasteride pills help slow down hair loss and stimulate new hair growth. Taken on a daily basis, these pills reduce DHT levels by up to 60%, allowing the once vulnerable hair follicles to thrive.
Finasteride is not recommended for women and is known to cause severe birth defects in male fetuses when handled by expectant mothers. It is vaunted by the AHLA as the most prolific drug to combat hair loss in men.
If you are suffering from permanent hair loss, a surgical solution may be your best option for reversing frontal baldness. According to WebMD, hair replacement procedures include hair transplants such as micro-grafting, punch grafting, and slit grafting. In hair transplant procedures, tiny skin plugs with DHT resistant hair follicles are removed from the side or back of the head and grafted on the balding sections of the scalp.
The transplanted hair falls out in three to four weeks after the surgery and new hair growth occurs after several months. The American Hair Loss Association lauds hair replacement but cautions against dangerous and outdated procedures such as scalp replacement, hair flap, and hair lifts.
Although effective, surgical treatments are quite expensive and patients are highly advised to seek out qualified surgeons in order to get the desired results without undue complications.
