In the treatment of hair loss different shampoos and other hair products can be used to minimise or prevent further loss but most of the 'medical' ones will contain Minoxidl or 'Rogaine' a drug which was originally used as a high blood pressure treatmment but patients noticed that they were regrowing hair in some thinning or bald places Research was carrried out and seemed to confirm that a solution of minoxidil applied onto the scalp could re-stimulate hair to start growing again.More studies and trials were carried out and as a result, over-the-counter minoxidil was FDA-approved for the treatment of androgenetic alopecia in women.
The drug usually takes about two months to start working but can take longer and users need to keep using the product to maintain results. Some patients can develop an irritating allergic reaction, but this is likely to be caused by the amount of alcohol in the product. Use should be discontinued if this happens and another consultation with a health professional should take place. It is also important to note that the product doesn't work for everyone and wont replace the original thickness of the hair.
