A little information on Male Baldness

Baldness is a painless and slow process of hair loss and most of the cases it comes with the increasing of age. It is also a natural process and most runs in a family. It is known as androgenetic alopecia.

At normal condition, about 100 hairs on the scalp are shed every day, and the hair is replaced about every 4 years. Approx 60% of men, by the age of 50, usually have significant hair loss.

What is the normal pattern of male baldness?

Initially, the front hairline starts to recede in the temple and frontal area. At the same time the hair over the crown(top) start becoming thin (look at the picture).

In some men, this condition may persist rest of his life while in others, the top and frontal area eventually meet, and ultimately affect the whole head (scalp). Those who start losing hair in their earlier age are affected more in the long run.

What are the causes of male baldness?

• In the majority of case, male baldness is a normal process. With the advancement of ages, it comes but if it runs in a family, it invariably comes to every male indicating that it might have some genetic influences.
• Male hormone (Testosterone) plays an important role here. It is believed that if a man is castrated at the young age, he won't go bald.
• In some rare instance, sudden severe illness might cause hair loss but when the illness is over, they return back (usually within 3 months).
• Some chronic illness (long-standing) also might be a causative factor, notably thyroid disorders and iron deficiency anaemia. Also, some fungal infections of the scalp can cause bald patches (total head baldness is unusual in fungal infection)
• Cytotoxic drugs, mostly used in cancer patients, can cause hair loss but when the drug is stopped, hair usually regrows.
• There is a specific hair loss disorder known as alopecia which may present as round bald patches (alopecia areata) or may involve the whole head (alopecia totalis)

What measures should be taken?

• Although it is embarrassing and upsetting initially, most men accept this natural baldness eventually. Moreover, it is an incurable condition (mostly). A doctor also doesn't have much to do except persuade them accepting the baldness.
• Those who can't accept it they may try these: A toupee, or a wig, or cutting hair very short and keep it that way, or go for hair transplant (the implanted hair might have same fate of that original hair)
• Regarding medications: Medicated shampoos and ointments don't do much help, and should be avoided. The tempting commercial advertisement also doesn't do any differences. Two drugs are currently available which might help. One is Minoxidil lotion/gel (to apply directly to the scalp) and another one is Finasteride (Tablet). But we should keep in mind that these are expensive, not equally effective for everybody and (if have a good result) need to continue rest of the life.
