4. Tea Tree Oil

Tea tree oil is renowned for its powerful antibacterial and antifungal properties, making it a top choice for acne and scalp care. As a spot treatment, it’s often compared to benzoyl peroxide but is typically less irritating for most users. Tea tree oil can help reduce redness and inflammation, clearing blemishes and soothing itchy, flaky scalps. Just remember to dilute it before applying to skin for the best, safest results.
