So, let’s say you’ve ruled out head lice and scabies. If you’re still asking “why does my scalp itch,” then dandruff is your most likely culprit. Or more specifically, seborrheic dermatitis, which is considered a severe form of dandruff caused by an overreaction the body has to normal yeast that lives on the skin, according to Jennifer Haley, MD, a board-certified dermatologist based in Scottsdale, Arizona. Dandruff affects about 40 percent of people and tends to come and go during one’s lifetime. “Weather changes, stress, and increased sugar in the diet can bring it out.”
Over-the-counter remedies include products containing the active ingredient, salicylic acid (such as Neutrogena T/Sal Shampoo) and products containing antifungals such as ketoconazole or selenium sulfide (Selsun Blue Shampoo contains the latter). Natural remedies for dandruff include tea tree oil. And a product called Scalpicin can help decrease itching, Dr. Haley advises. If over-the-counter remedies do not resolve the issue, then see a board-certified dermatologist, who can not only prescribe steroidal anti-inflammatories but also determine if some other condition is causing your itchy scalp symptoms.
