Start with the cause of hair loss

Different causes can call for different approaches. The American Academy of Dermatology explains that effective treatment starts with finding the cause and that no one treatment works for everyone. A qualified healthcare professional can evaluate sudden, unexplained or concerning hair loss and advise on medical treatments.

Compare claims with evidence

When considering a product, check its active ingredients, intended use, instructions, possible risks and evidence for your condition. Do not assume that a shampoo, supplement or cosmetic system has been shown to regrow hair. For non-surgical cosmetic coverage, see our hair replacement guide; for questions about currently stocked products, contact the studio.
