Understanding Male Pattern Baldness: Why Crown Hair Loss Occurs First

Male pattern baldness, also known as androgenetic alopecia, is a common condition that affects men. It is caused by a combination of genetics and hormones.

- The main hormone responsible for male pattern baldness is testosterone. Testosterone is converted to a substance called dihydrotestosterone (DHT) by an enzyme called 5-alpha-reductase. DHT binds to receptors on hair follicles, causing them to shrink and eventually stop producing hair.

- The hair follicles on the top of the head are more sensitive to DHT than the hair follicles on the sides and back of the head. This is why men typically lose hair on the top of their head first.

Other factors that can contribute to male pattern baldness include:

- Age: Male pattern baldness typically begins in men in their 30s or 40s, but it can start earlier or later.

- Family history: If your father or brother has male pattern baldness, you are more likely to develop it yourself.

- Obesity: Obese men are more likely to develop male pattern baldness than men who are not obese.

- Certain medical conditions: Some medical conditions, such as diabetes and thyroid disease, can cause hair loss.
