Yes, no matter the cause, dermatologists are adept at finding treatments which can help hair grow back after thinning. Viviscal PRO vitamins taken twice daily can stimulate hair growth no matter the cause. Topical minoxidil (such as Rogaine) can also be used to stimulate hair growth. Diagnosing the cause of the hair loss is important in deciding which prescription products might be helpful, and therefore, an appointment with a board-certified dermatologist for evaluation is highly recommended.
