Hair Loss in Men

Male pattern baldness, also called androgenetic alopecia, is primarily caused by genetics and hormones. The main culprit is dihydrotestosterone (DHT), a hormone derived from testosterone that shrinks hair follicles over time. Men who are genetically predisposed have hair follicles that are sensitive to DHT, causing them to gradually become smaller and produce thinner, shorter hairs until they eventually stop producing hair altogether. This process typically follows a predictable pattern, starting with a receding hairline and thinning at the crown, which is why it’s called “pattern” baldness.

Male pattern baldness can begin as early as the late teens or early twenties, though it more commonly becomes noticeable in the thirties and forties. About 25% of men begin experiencing some degree of hair loss by age 25, 50% by age 50, and about 80% of men show some signs of hair loss by age 80. However, the timing and severity vary greatly based on genetics. Some men may notice gradual thinning in their twenties while others maintain a full head of hair well into their fifties or beyond.

The most proven treatments for male pattern baldness include finasteride (Propecia), a prescription pill that blocks DHT production, and minoxidil (Rogaine), a topical solution that stimulates hair growth. Hair transplant surgery is highly effective for more advanced hair loss and provides permanent results. Newer treatments include platelet-rich plasma (PRP) therapy, low-level laser therapy, and microneedling. The key is starting treatment early, as these therapies work best to maintain existing hair rather than regrow hair in completely bald areas.

Hair loss from male pattern baldness is generally permanent without treatment, but the progression varies significantly between individuals. If you’re noticing a receding hairline, thinning at the crown, or overall decreased hair density that has been gradually worsening over months or years, this is likely permanent pattern baldness. Temporary hair loss from stress, illness, or medications typically affects the entire scalp rather than following the classic pattern, and hair usually regrows once the underlying cause is addressed. A dermatologist can help determine the cause and whether your hair loss is likely to be permanent.

Avoid harsh treatments that can damage existing hair, such as aggressive brushing, tight hairstyles, excessive heat styling, or chemical treatments like perms and bleaching. Don’t fall for miracle cures or expensive shampoos that promise to regrow hair, as most have no scientific backing. Avoid waiting too long to seek treatment, as hair loss treatments work best when started early. Don’t assume that wearing hats or frequent shampooing causes hair loss, as these are common myths. Also avoid crash diets or extreme stress, as these can accelerate hair loss in men who are already predisposed to pattern baldness.
