Wondering what causes thinning hair in women? While seeing changes in the thickness of your hair might be concerning, it's completely normal in many cases and not usually something to worry about.
All of our hair follicles undergo phases of growth, during which the hair lengthens, followed by a period of rest (called the telogen phase). This is when hair falls out and new hair replaces it. If something happens during the latter stage of this cycle to prevent the regrowth, some areas may start to thin out. It can also be one of the main causes of hair loss in women.
