That persistent scalp itch isn’t just annoying—it’s your body’s way of signaling that something may be off. While a little itching now and then is normal, chronic or intense discomfort can point to underlying issues ranging from skin conditions to lifestyle factors. Understanding the causes is the first step toward lasting relief.

Tips for Everyday Scalp Care
