Whether hair loss requires treatment or not depends to a great deal on the underlying causes and the general psychological disposition of the man involved. In other words, if losing your hair makes you feel miserable, you may want to consider treatments, but if you are happy enough with it, let it go and keep smiling. Temporary hair loss caused by medical treatments typically does not require help to sooner or later grow back naturally. If infections or conditions like discoid lupus or lichen planus, for example, have caused the loss, the conditions should be treated, as opposed to dealing with the hair loss.
As far as natural ageing and male pattern baldness are concerned, the best treatments currently available are Finasteride or Minoxidil, neither of which are available on prescription.
This treatment prevents testosterone from being converted into dihydrotestosterone, better known simply as DHT. This hormone induces hair loss by causing hair follicles to shrink. By reducing the production of DHT, hair follicles are allowed to regain/ maintain their regular size. According to studies, this treatment can increase hair count and improve the way people think their hair appears.
As a rule, it will take approximately two to six months before the effect of this treatment, which is taken in the shape of a pill, becomes noticeable. Should the treatment be stopped, the balding process typically resumes within approximately six to 12 months. It is uncommon for side effects to be noted, although a minute percentage (less than 1%) of men taking Finasteride may experience erectile dysfunction or loss of libido.
This treatment comes as a lotion to be rubbed into the scalp. Available from pharmacists, it is available in solutions containing 2 or 5 % of Minoxidil. While it is unsure as to exactly how this treatment works, evidence has show that it can encourage re-growth of hair. Opinions as to whether the 5 % solution is more effective than the 2% version differ, but it is believed across the board that the former may cause itchiness or dryness of the scalp to a greater extent than that of the latter, although side effects are generally fairly uncommon.
This product also needs to be used continually, as stopping usage will result in re-grown hair falling out again within around two months of stopping the treatment.
For a more permanent, non-chemical solution, it is best to look for hair transplant surgery. Typically regarded as the most effective and long-lasting solution, this type of treatment an, however, be expensive. As baldness is not regarded as an illness, it is not available through national health services, and prices can vary depending on where surgery is provided and the extent of the required work involved.
In some cases, segments of scalp carrying healthy hair follicles at the back of the head are moved to frontal areas of baldness. In other instances, a process known as scalp reduction is performed. This involves removing sections of scalp with defective hair follicles and stretching scalp sections featuring healthy follicles.
