Without fail, whenever the weather changes the slightest degree, my scalp starts to itch. But it's not just weather fluctuations that cause dandruff and scratchiness. Your scalp can go haywire due to product buildup, water that's too hot, or even an underlying skin condition. One of the most effective ways to treat this issue is by investing in one of the best tea tree shampoos for dandruff and itchy scalps. Typically, they're a much more natural alternative to most chemical-laden, sulfate-packed shampoos, but they work just as well. Tea tree is an essential oil that's useful in breaking down bacteria and fungi, and since dandruff is, in fact, a fungal condition, tea tree's anti-fungal properties are great at kicking flakes to the curb.
There are a few things to keep in mind, however. Since tea tree is an essential oil, some folks may be allergic to it. So if you're someone whose skin tends to flare at the smallest whiff of oil, perform a patch test (it's usually recommended to do this on the inside of your elbow) before smothering your scalp in shampoo. Also, you might not need to use your tea tree shampoo every time you wash your hair. Once a week might be enough, and you can alternate with a hydrating formula for a balanced and overall healthy scalp.
