If you are losing hair, the first expert to see is a dermatologist. Dermatologists specialize in skin, hair, and nail conditions. They can diagnose the cause of hair loss and recommend treatments. For some people, starting with a primary care doctor makes sense too, especially if you have other symptoms like fatigue or weight changes. Your primary care doctor can run initial tests and refer you to the right specialist. The best expert depends on what is causing your hair loss.
Which Doctor to Consult for Hair Loss First?
Start with a dermatologist. Hair loss is a medical condition, and dermatologists have the most training in diagnosing and treating it. They can perform a scalp exam, pull tests, and sometimes a scalp biopsy to find the cause. Most types of hair loss, including male and female pattern baldness, alopecia areata, and telogen effluvium, fall under their care. Some dermatologists also offer treatments like topical minoxidil, oral finasteride, or platelet-rich plasma (PRP) injections. If your dermatologist suspects an underlying medical issue, they will refer you to another specialist.
What Does a Dermatologist Do for Hair Loss?
A dermatologist begins by taking your medical history and asking about your hair loss pattern, stress, medications, and family history. They examine your scalp with a device called a dermatoscope. This helps them see the hair follicles and skin details. If needed, they may pull a small sample of hair to look at under a microscope. In some cases, they take a tiny piece of scalp skin (biopsy) to confirm the diagnosis. Based on the findings, they can recommend treatments backed by research, such as minoxidil (Rogaine), finasteride (Propecia), or corticosteroid injections for alopecia areata. They can also rule out scalp infections or other skin conditions that cause hair loss.
When Should You See a Primary Care Doctor?
See your primary care doctor if you have other symptoms along with hair loss. Fatigue, unexplained weight changes, feeling cold, or menstrual irregularities may point to an underlying condition such as thyroid disease, anemia, or a hormonal imbalance. Your primary care doctor can order blood tests to check thyroid hormones, iron levels, vitamin D, and sex hormones. If the tests show a problem, your doctor can treat it or refer you to a specialist. Even without other symptoms, some people prefer to start with their primary care doctor for convenience. That is fine, but a dermatologist is often the more direct choice for the hair itself.
Can an Endocrinologist Help with Hair Loss?
Yes, an endocrinologist is useful when hair loss is related to hormone problems. Conditions like polycystic ovary syndrome (PCOS), thyroid disorders, and menopause can cause hair thinning. An endocrinologist specializes in the endocrine system, which includes glands that produce hormones. They can diagnose and treat these underlying issues. For example, if you have PCOS, balancing hormones with medication may slow hair loss. If you have an overactive or underactive thyroid, treating that condition often helps hair regrow. Most people see an endocrinologist only after a dermatologist or primary care doctor finds a hormone abnormality.
What About a Trichologist?
A trichologist is a specialist in hair and scalp conditions. However, trichologists are not medical doctors. They cannot prescribe medications or perform medical procedures. Their training varies, and there is no single national standard for certification in the United States. Some trichologists offer valuable advice on hair care and non-prescription treatments. But for a medical diagnosis or prescription treatment, you should see a board-certified dermatologist instead. If you see a trichologist, make sure they work alongside a medical doctor or refer you to one when needed.
Other Specialists Who May Be Involved
Depending on the cause of your hair loss, you might see a rheumatologist, gynecologist, or psychiatrist. A rheumatologist treats autoimmune diseases like lupus, which can cause hair loss. A gynecologist can help with hair loss related to menopause or PCOS. A psychiatrist or therapist can help if stress, depression, or eating disorders contribute to hair thinning. In all these cases, the hair loss is usually a symptom of a broader problem. Treating the underlying condition often improves hair growth.
How to Choose the Right Specialist
Start with the most likely cause based on your symptoms. If you have a receding hairline or bald patches and no other health changes, go to a dermatologist. If you also feel tired, cold, or have heavy periods, start with your primary care doctor for blood work. If you already know you have a hormone disorder, an endocrinologist may be the best choice. Always ask your primary care doctor for a referral if your insurance requires it. You can also call a dermatologist’s office directly to ask if they treat hair loss. Many dermatologists now list hair loss as a specialty.
What If You Are a Woman with Hair Loss?
Hair loss in women is common and often different from male pattern baldness. Women are more likely to have diffuse thinning over the top of the scalp. The causes can include pregnancy, menopause, stress, and underlying medical conditions. A dermatologist who specializes in hair disorders in women is a good first choice. Some dermatologists have extra training in female pattern hair loss. Your doctor may recommend blood tests to rule out iron deficiency, thyroid problems, or hormonal issues. Female pattern hair loss is treatable with minoxidil and sometimes other medications, but results vary.
What About Hair Loss in Men?
Male pattern baldness is the most common cause of hair loss in men. It is genetic and hormone-related. A dermatologist can confirm the diagnosis and offer treatment options. FDA-approved treatments include minoxidil and finasteride. Low-level laser therapy and platelet-rich plasma (PRP) are also available but have less strong evidence. Men with sudden or patchy hair loss should also see a dermatologist, as this may be alopecia areata or a scalp infection. Early treatment often gives better results, so do not wait.
