Tea tree oil for hair growth: How does it help?
“Tea tree oil does not directly grow hair, like a medicine, but it creates a scalp environment perfect for healthier and stronger hair growth,” says aesthetic physician and cosmetologist Dr Karuna Malhotra. It can particularly promote hair growth when mixed with certain medicines.
During a study, published in Drug Design, Development and Therapy, a mixture of tea tree oil, diclofenac (nonsteroidal anti-inflammatory drug), and minoxidil (medication for hair growth) was found to be more effective than using minoxidil alone in boosting hair growth.

Here are the benefits of tea tree oil for hair growth:
1. Clears blocked hair follicles
“One of the most common reasons for poor hair growth is clogged follicles, which is caused by excess oil (sebum), dandruff, product build-up and dead skin cells,” says the expert. Tea tree oil acts as a natural cleanser for the scalp, and helps to unclog hair follicles and remove residue. This lets hair to grow more freely and in a healthier way.
2. Reduces scalp inflammation
A calm scalp is very important for growth. Inflammation and itching, often due to fungal or bacterial overgrowth, can damage hair follicles. Tea tree oil has strong anti-inflammatory properties, according to research published in The Journal Of Clinical And Aesthetic Dermatology. Its anti-inflammatory properties can help reduce redness and irritation of the scalp, soothe skin and support follicular strength.
3. Fights dandruff
It also has antifungal and antibacterial properties, especially effective against the fungus Malassezia, which is known to cause dandruff. A study, published in Current Cosmetic Science, showed that shampoo with tea tree oil can combat dandruff. “This common hair problem can disrupt hair growth by weakening follicles and causing flaking and scratching,” says Dr Malhotra. Tea tree oil for hair growth can work, as it reduces flaking and microbial overgrowth. This restores the scalp’s natural balance, and promotes better hair growth.
4. Improves blood circulation
When massaged into the scalp with a carrier oil, tea tree oil may help stimulate blood flow. This way it can help to transport more oxygen and nutrients to the hair follicles. “A well nourished follicle is an active follicle, and better blood circulation encourages hair to grow in a healthier, thicker cycle,” says the expert.
