Chemical Damage Caused Hair Loss

My question is that I lost a lot of hair from checmical damage such as excessive dying. Will my hair ever grow back? It has been four and half years and it has yet to grow. I am still very young and this has affected my psychological well being. Is rogaine safe to use, considering my hair loss is not genetically related?

Thanks

If your hair has not grown back after 4 1/2 years, then I do not believe that it will grow. Yes, chemical damage can injure your hair roots or the scalp itself, leading to possible permanent hair loss. You may try Rogaine. If you are a male, then I recommend Propecia also. Keep in mind that there is no substitute for a good doctor giving you a real diagnosis in person so that you KNOW what you have and what the prospects are for you.
