Baldness in teenagers is relatively uncommon, but it can happen. The most common cause of baldness in teenagers is a condition called alopecia areata. Alopecia areata is an autoimmune disorder in which the immune system attacks hair follicles, resulting in hair loss. This condition can affect people of all ages, including teenagers.

Other factors that can cause baldness in teenagers include hormonal changes, nutritional deficiencies, fungal infections of the scalp, and certain medications. Stress and trauma can also lead to hair loss.
It is important to note that hair loss can be distressing and have a significant impact on a teenager’s self-esteem and mental health. Therefore, it is essential to address the underlying cause of the hair loss and provide emotional support to the affected individual.
