Improper hair care, a stressful event, a physical condition that alters your hormone levels—these are a few things that can literally make your hair fall out. You may notice your hair thinning or observe losing more strands than the normal amount. Most causes of hair loss, like too much hair bleaching or dye jobs, or styling the hair with tight braids and hair ties, can be altered to gradually get rid of the problem. In other causes, like pregnancy and chemotherapy, hair regrowth normally happens after.
There are some factors, however, that you cannot control or those that are difficult to resolve, which would urge you to get hair transplants.
