Which Doctor Treats Hair Loss?
Hair loss is excessive shedding or absence of hair growth. It can result from genetics, hormones, stress, nutritional deficiencies, or medical conditions.
Hair loss can be emotionally distressing whether you're noticing more hair in the shower, a receding hairline, or thinning on the scalp. Losing up to 100 hairs daily is normal, but excessive shedding or gradual thinning warrants medical evaluation. Hair loss can result from genetic predisposition, hormonal changes, stress, nutritional deficiencies, thyroid disease, or autoimmune conditions. The cause matters because different types of hair loss require different treatments. Understanding what kind of doctor should I see for hair loss helps you get accurate diagnosis and effective treatment.
Start with your primary care physician who can perform blood tests to check for thyroid disease, iron deficiency, and nutritional problems that commonly cause hair loss. A dermatologist specializes in hair loss and can identify the specific type of alopecia and recommend appropriate treatments including topical medications, oral drugs, or hair restoration procedures. If hormonal imbalance is suspected, an endocrinologist can evaluate thyroid, pituitary, and adrenal function. Early evaluation is important because some types of hair loss respond better to treatment when caught early.
While genetic male and female pattern baldness cannot be completely reversed, medications like minoxidil and finasteride can slow hair loss and regrow some hair. Other causes of hair loss are often completely reversible once the underlying cause is treated. With proper diagnosis and treatment, many people see significant improvement in hair growth and thickness.
