Always comb hair gently and use a mild shampoo. As hair starts to thin, consider cutting it short or even having it neatly clipped to the scalp by a professional stylist. The close-cropped or “shaved head” look is popular with many men and can offset concerns abut patchy hair loss. Just remember, doctors caution against shaving the scalp with a razor, which can cause hard-to-heal cuts that can result in infection when blood counts are low.
