Female Hair Loss There is no set pattern for female hair loss. Some women don’t start to lose their hair until later on in life, others find their hair thinning while they are relatively young. Many women feel isolated and alone when their hair starts to thin but it isn’t uncommon. In fact, more than 1 in 4 women inherit thinning hair. Many people believe that hair dryers and tongs can cause women to lose hair. This is not the case. Over-treating and coloring hair can have an adverse effect and might even cause hair to break off near the scalp but it can’t cause long-term hair loss. There are many reasons for women to lose their hair but the most common is hereditary thinning or alopecia which accounts for 87% of female hair loss.
