The Role of Genetics in Hair Loss

Hair loss, or Alopecia, occurs more commonly in individuals who have a genetic predisposition to balding. This type of loss can affect both men and women, although it is a lot more common in men, and often referred to as male pattern baldness. This name came about because of the way that hair sheds—never all at once, and usually in stages or a typical pattern around the head.

Onset of hair loss occurs in adulthood (regardless of age, so can affect a man in his twenties much the same as one in his fifties), and in cases when hair regrowth is difficult or impossible,
there are several hair restoration solutions that can be applied to give you back a healthy head of hair. Read more below about how your genetic build-up plays a role in your hair loss, and find out what you can do about your balding situation.

The genetics of hair loss explained

Androgenetic Alopecia, also known as male pattern baldness, is by far the most common cause of hair loss. It is said that looking at your mother’s side of the family for signs of baldness will determine whether you can expect to experience the same. As much truth as there may be to this statement, it is not that cut-and- dried. This condition is natural, and brought about by a combination of genetics, the ageing process, and hormone levels. Additional factors affecting hair loss include nutritional deficiencies, overall health, exercise, thyroid problems, and more. What this ultimately means, is that though Alopecia runs in your family, there are many other factors that need to be present in order for it to affect you as well.

The Role of Genetics in Hair Loss

As people age, it is quite normal to experience a certain amount of shedding and/or thinning of the hair. However, in the case of Androgenetic Alopecia (which affects about 40% of men), this shedding and thinning will be a lot more pronounced. It typically starts between 20 and 30 years of age, and worsens as it moves through seven gradual stages. Thinning of the hair starts in the area around the temples or the crown of the head. A receding hairline results in the temples becoming larger with time. At this stage, a line of healthy hair separates it from the thinning crown, which slowly increases in size as the hair density decreases. Eventually the remaining healthy hair will also thin out until finally disappearing altogether, leaving you with the typical appearance of baldness.

The male hormone testosterone plays a significant role in hair loss by disrupting and effectively altering the normal cycle of hair growth, and also hair regrowth. The result is thinner, shorter (miniaturized) hair. As the condition progresses, this miniaturization of the hairs leads to growth stopping entirely, causing pattern baldness.

A permanent solution to hair loss / balding

Although this type of hair loss is permanent, fortunately there are several hair restoration solutions available. Some treatments are more successful and permanent than others, and it
would do well to consult with a professional on the matter in order to determine which path would be best suited to your individual case.
