Tea tree oil is widely used in skincare products for its antimicrobial and anti-inflammatory properties. It is commonly applied to treat acne, as it helps reduce redness and swelling while combating bacteria that cause breakouts. The oil is also used in shampoos and conditioners to address dandruff and scalp irritation, promoting healthier hair and skin. In aromatherapy, it is valued for its refreshing scent and ability to clear nasal congestion. Additionally, tea tree oil is found in natural cleaning products due to its ability to disinfect surfaces and eliminate odors. It is often diluted and used as a natural remedy for minor cuts, insect bites, and fungal infections like athlete's foot. Always perform a patch test before use to avoid potential skin sensitivity.
