The leading cause of hair loss in men is male pattern baldness, also known as androgenetic alopecia. Male pattern baldness is characterized by hair receding from the lateral sides of the forehead (known as a “receding hairline”) and/or a thinning crown (balding to the area known as the ‘vertex’). Both hair recession and hair thinning become more pronounced until they eventually meet, leaving a horseshoe-shaped ring of hair around the back of the head.
Male pattern baldness occurs in men whose hair follicles are sensitive to the hormone dihydrotestosterone (or DHT). Over time, DHT-sensitive hair (usually found on the top and at front of the head) becomes weaker and finer and eventually stops growing. However, even men who experience advanced hair loss typically have healthy hair follicles around the sides of the head. Even though these healthy hairs are exposed to DHT, they are resistant to this hormone and survive for a lifetime.
This is the basis of surgical hair restoration. The procedure works by transplanting these DHT-resistant healthy hair follicles located around the sides and at the back of the head to the areas where more hair is needed (frontal and top).
Men who develop pattern baldness begin to lose their hair any time after puberty when presence of androgenic hormones increase. However, the amount of androgens present does not need to be greater than normal for male pattern baldness to occur. If androgens are present in normal amounts and the gene for hair loss is present, male pattern hair loss will occur. Hair receding in the temporal areas is normally the first sign in approximately 96 percent of mature Caucasian males, including men who are not predisposed to experience further hair loss. In some men, initial male pattern hair loss may be delayed until their late thirties or forties.
Axillary (under arm) and pubic hair are dependent on testosterone for growth. Beard growth and male pattern hair loss are dependent on dihydrotestosterone (DHT). Testosterone is converted to DHT by the enzyme, 5 -reductase. Finasteride (Propecia®) acts by blocking this enzyme and decreasing the amount of DHT. Receptors exist on cells that bind androgens. These receptors have the greatest affinity for DHT followed by testosterone, estrogen, and progesterone. After binding to the receptor, DHT goes into the cell and interacts with the nucleus of the cell altering the production of protein by the DNA in the nucleus of the cell. Ultimately growth of the hair follicle ceases. The hair growth cycle is affected when both the percentage of hair growth and the duration of the growth phase reduces, resulting in shorter hairs. More hairs are then said to be in a resting state and these hairs are much more subject to loss with the daily combing and washing. With time, the hair shafts in male pattern baldness become progressively smaller in diameter and length. In men with male pattern baldness, all the hairs in an affected area may eventually (but not necessarily) become involved in the process and may with time cover the region with fine hair. Pigment (colour) production is also terminated so the finer hair becomes lighter in colour. Lighter colour and smaller hairs cause the area to first appear thin. Men can completely lose all follicles in these areas over time.
Hair Loss in Women
Hair loss in women can be related to genetics, hormones and age. Although this is not the leading cause of hair loss in women, androgenetic alopecia is still relevant. It may be a serious medical condition which needs proper attention and treatment as early as possible. The hair loss patterns in women also usually differ compared to male hair loss.
