It is possible that chemicals can lead to hair loss. If you use chemicals on your hair, it is best to let a licensed beautician do it. They are able to properly perform chemical treatments to your hair. Also, if you color your hair, do it no more than every 6 to 8 weeks.
One of the best methods of preventing the progression of hair loss in men is to take Propecia or finasteride. When this prescription medication is taken daily, almost all men note that their hair loss stops. Some men even notice a regrowth of hair. This medication must be taken for life, because once a person stops taking it, the pattern of hair loss recurs.
Make sure that you wait until your hair has dried before attempting to brush it. Wet hair is susceptible to damage. Dry hair is much better at handling a good hard brushing. You can damage your hair if you brush it when it is wet and make it split.
