Excessive shedding usually returns to normal after six to nine months, but chronic stress might cause it to lead to permanent hair loss. When taking out your hair, proceed with caution. Teenagers sometimes play with their hair inadvertently, spinning or pulling on it. This can result in thinning hair or scalp pain. If you are concerned about your hair loss, ask your doctor for a referral to an otolaryngologist (ear-nose-and-throat doctor). These specialists can help diagnose hair loss and other related conditions of the head and neck such as alopecia (loss of scalp hair) and hirsutism (hair growth). Alopecia areata is a condition where the body's immune system attacks hair follicles, causing them to shut down. This can also be caused by drugs, chemicals, or infections. Hair loss is usually temporary but may become permanent if you continue to damage hair follicles. Your dermatologist can advise you on ways to protect your hair and manage symptoms. If you suffer from hair loss, make sure to take care of yourself physically and mentally; this will help you cope with the situation.
