There are a number of factors that can contribute to poor hair growth after hair restoration surgery. Some have preoperative causes, while others result from something that happens during or after the surgery.
Many people wonder what causes hair loss. The causes of hair loss vary depending on a number of factors, including genetics (this is often what causes baldness or alopecia), illness (such as thyroid disease), and medications you may be taking. The best way to uncover hair loss causes and find out whether they are preventable is to see a physician.
What causes hair loss in men and women is also related to lifestyle. Factors such as stress, exposure to chemicals or UV rays, smoking and consuming alcohol can play a role in triggering or exacerbating the loss of hair (and can also affect recovery from hair restoration surgery). It is also important to be aware that certain types of hairstyles, including braids, tight ponytails and hair extensions, can cause tension and trauma to the hair follicle, leading to hair loss.
