Hair Loss Causes in Men
Hair loss in men, also known as male pattern baldness or androgenetic alopecia, is a common condition that can have various causes. The primary cause of hair loss in men is genetic, but there are other factors that can contribute to or exacerbate the condition.
What causes hair loss, and what can you do about it?
The most common cause of hair loss in men is male pattern baldness, also known as androgenetic alopecia. This condition is largely influenced by genetics and hormonal factors, primarily the hormone dihydrotestosterone (DHT). Men with a family history of hair loss are more likely to experience it themselves. DHT can shrink hair follicles, leading to a gradual thinning of the hair and eventual baldness. Male pattern baldness typically progresses in a specific pattern, starting with a receding hairline and thinning at the crown, and it becomes more prevalent as men age. While it is a natural part of aging for many men, various treatment options are available to manage and, in some cases, slow down the progression of this common form of hair loss.
Hair Loss: The Norwood Scale
CLASS 1
There is no visible hair loss.
CLASS 2
The hairline begins to recede with some recession in the temple region.
CLASS 3
There is a significant decline in the amount of hair above the temples and forehead. At its peak, class 3 includes significant hair loss on the crown.
CLASS 4
The hair loss has become more noticeable on the crown, or patients may have significant hair loss above the temples and/or forehead.
CLASS 5
The hair loss now affects the front and back of the scalp. Only a small area of the front hairline remains, and a large balding area exists on the top of the scalp.
CLASS 6
At this point, the hair loss is so advanced that the hair bridging the sides of the head is nearly or completely gone. There may still be sufficient donor hair for transplantation, but results may be limited.
