It's obvious,  that most men don't want to lose their hair. Yes, there are many men that are  perfectly fine with balding and are able to embrace their hair loss, however  the majority of US men become frustrating when their hair starts to thin and  more bald spots appear on the head. And to make things even more uncomfortable,  there is a very wide range of reasons for why a man can lose his hair and each  type of causes requires different types of treatment.

The main  causes for hair loss in men arise form nutritional, genetic, hormonal and  circulatory problems that might affect other aspects of men's health as well.  Of course, all of these factors manifest themselves in different forms, however  they still have pretty much the same nature behind them And the effects of such  problems are usually manifested through the weakening of the hair follicles and  reduction of natural hair growth rates that consequently leads hair loss.
Typical  causes of hair loss in men

There are  many different factors that can cause hair loss in men and it is crucial to  define them at the initial stage of hair loss when something can be done. A  serious illness, surgery or even trauma can become the catalyzing element for  developing processes in the body that will ultimately lead to hair loss. Fungal  infections, various diseases and even excessive stress can contribute to hair  loss problems, too. So as soon as you notice any signs of balding and feel that  there is a serious health concern you should contact your doctor as soon as  possible.

Hair loss  can also be triggered by certain medications or treatments (such as  chemotherapy for cancers), and hormonal imbalance. However, most commonly hair  loss in men is caused by the accumulation of dihydrotestosterone (DHT) and  genetics. Back in the day, healthcare providers were confident that genetics  play a very important part in the process of hair loss, and if a man becomes  bald it's his genetic predisposition that causes the problem. However, numerous  studies conducted recently have put genetics a bit back and showed that DHT has  a much more important role in the process of hair loss.

About DHT

DHT was  found to be the primary cause for the so-called male pattern hair loss, also  referred to as Androgenetic Alopecia. This type of hair loss is most common in  men (hence, the name) and is characterized by the thinning hairline and balding  in the crown area that consequently spread over the entire scalp. DHT itself is  an androgen, a male hormone, which is produced from another hormone,  testosterone. The problem with DHT is that when there's too much of it in the  body and it comes into contact with hair follicles they start to shrink and  become weak. The natural hair growth rates drop and the hair that is lost  normally (150-200 hairs per day) doesn't grow back in quantities that would  keep the natural hair numbers constant.

The good  news with DHT is that there are drugs like Propecia that are specifically  targeted at the prevention of the transformation of testosterone into DHT.  However, before you buy Propecia, you have to make sure that your hair loss is  caused by excessive levels of DHT rather than any other factor.
