If your hair has started to get thinner recently, it’s time to find out why. In this blog, we explain four causes of male hair loss.

Genetics and hormones

The most common reason for men to experience hair loss is carried in their genes. Androgenetic alopecia, also called male pattern baldness, occurs in people who are genetically sensitive to the effects of DHT. This testosterone by-product causes the hair follicles to shrink and shortens the hair growth cycle, leading to weaker growth and hair loss. Androgenetic alopecia causes permanent hair loss and can start in a man’s early to mid-20s with the likelihood of it developing increasing with age.


Another common cause of male hair loss is stress. Telogen effluvium tends to occur around three months after a stressful situation, whether it is a sudden shock or longer period of stress. The condition occurs because, in stressful situations, our bodies reduce non-essential activities such as hair growth. Telogen effluvium can be experienced by men at any age and is not usually permanent.


Many men don’t realise that their diet could be causing their hair loss. According to various studies from around the world, men’s diets frequently do not contain enough of some nutrients, including magnesium and Vitamin B12. Absorption of nutrients can also be hindered by smoking, some medications and health conditions. When we don’t give our bodies an adequate supply of these nutrients, our follicles are unable to produce healthy hair and hair loss may be triggered. Nutritional deficiencies can happen at any age and it is usually possible to regrow the hair if the diet is changed and/or supported with an appropriate nutrient supplement.

Auto-immune disorders

Auto-immune disorders, such as alopecia areata and alopecia universalis, are less common than other causes of hair loss in men. These types of condition occur when the body’s own immune system malfunctions and starts to attack its own cells. In the case of alopecia areata, this results in round patches of hair loss on the scalp. Auto-immune conditions can develop at any age but often starts in childhood. When treated, hair lost to alopecia areata can regrow, however, in severe and prolonged cases, it may be permanent.
