Hair loss, also known as alopecia, can result from various factors, with the most common being male pattern baldness (MPB), or androgenetic alopecia.
MPB affects nearly half of men over 50 but can begin as early as the late 20s or early 30s. Women can also experience a similar condition, known as female pattern hair loss.
MPB is often hereditary and follows a distinct pattern of hair thinning, starting with a receding hairline and loss from the crown. In the scalp, testosterone is converted into dihydrotestosterone (DHT), and in MPB, hair follicles are more sensitive to DHT. This increased sensitivity causes the follicles to shrink, producing thinner, finer hair that grows for shorter periods before falling out. Over time, the follicles become too small to produce visible hair.
In women, androgenic alopecia affects around 50% of those over 65, typically leading to hair thinning on the top of the head. While a hereditary link is uncertain, it often becomes more noticeable after menopause. Other potential causes in women include polycystic ovary syndrome (PCOS), which increases testosterone levels.
Additional causes of alopecia include:
-
Alopecia areata
-
Seborrhoeic dermatitis
-
Thyroid disorders
-
Iron deficiency
Hair loss can be distressing for some individuals and may significantly impact self-confidence.
