Sometimes, the problem isn’t what you’re not doing—it’s what you are. Many hair products contain harsh chemicals that strip the scalp of its natural oils, leading to dryness and irritation.
One common culprit? Para-phenylenediamine—a chemical found in darker hair dyes and henna. Other common irritants include sulfates, parabens, and synthetic fragrances.
If your scalp is sensitive, try switching to sulfate-free, fragrance-free, or hypoallergenic hair products.
