Thinning hair is an ailment that both men and women suffer from. Hair can thin for several reasons, including genes, stress and unfavorable environmental conditions. There are steps you can take to slow or possibly stop the process of thinning hair.

1 Wash your hair with protein-infused shampoo. Whatever the cause of your hair thinning is, if you have weak hair follicles, it is sure to exacerbate the thinning. Using a protein-infused shampoo will help reinforce your hair's natural strength and reduce breakage.

2 Take hair-strengthening vitamins. Both biotin and vitamin B12 have shown to assist in the creation of new hair follicles. The creation of new follicles can help stop the appearance of thinning and help you grow new hair to replace what was lost.

3 Visit your doctor. There are several prescription cremes and medications that can be used to stop (or in some cases, reverse) hair loss. These medications do come with some risks and side effects, so it is important to have a lengthy discussion with your doctor before beginning any prescription treatment.
