Thinning Hair: Causes for Men

Written by: Prof. Dr. Ingo Stoffels

In simple terms, male pattern hair loss occurs when hair starts to thin in a predictable pattern on the scalp.

The main cause of this condition is a combination of genetic factors and hormones.

Here’s how it works

Some people have genes that make their hair follicles more sensitive to a hormone called dihydrotestosterone (DHT), which is derived from testosterone. When these sensitive hair follicles are exposed to DHT, it causes them to shrink over time. As the follicles shrink, the hair they produce becomes thinner and shorter with each growth cycle. Eventually, the follicles may stop producing new hairs altogether, leading to baldness in certain areas of the scalp.

So, it’s like a double whammy of genetics and hormones. If you have inherited the genes that make your hair follicles sensitive to DHT, and if you have high levels of DHT in your body, you are more likely to experience male pattern hair loss.

While there are other factors like age, inflammation, and environmental influences that can contribute to hair loss, the genetic and hormonal factors are the primary culprits in male pattern hair loss.
