If you are wondering, “Why do I have dandruff?” then you’re not alone. There are many possible causes and you can take action to treat it. One of the most common causes is seborrheic dermatitis. In some cases, people with dandruff also have the same condition in other parts of their body. In either case, the best thing to do is visit your doctor to determine what the cause of your dandruff is.
You may be using a tar-based shampoo that is irritating your scalp and causing dandruff. Using a tar-based shampoo may make it more sensitive to sunlight. Wear a hat outside if you’re going to be outside for a long time. It’s also important to avoid using it on colored or treated hair. Always follow the label directions and consult your doctor if you notice a significant change. A doctor may prescribe a stronger shampoo or topical steroids to treat your dandruff.
Once you identify the underlying cause, you can start addressing your scalp’s health. Dandruff is a common scalp problem that starts during early adolescence and continues throughout the adult years. For some people, it can last for their entire lives. Males are more likely to experience dandruff than females, but it can also occur in people with certain health conditions like HIV, Parkinson’s disease, or a weakened immune system.
