15 Hair Growth Oils That Will Completely Transform Your Tresses

Rosemary oil has been hailed as a hero ingredient, but it’s not the only one.

“Rosemary oil can also work to reduce hair damage and breakage, making the hair appear stronger. In addition to its antibacterial and antimicrobial properties, rosemary oil is also anti-inflammatory; it can help to reduce scalp redness and irritation and signs and symptoms of dandruff,” Dr. Garshick explains.

Another popular ingredient touted for its strengthening properties is castor oil, which “contains ricinoleic acid, a type of fatty acid, to may boost circulation in the scalp and subsequently promote healthier and stronger hair,” Dr. Garshick adds.

According to Dr. Camp, argan, tea tree, and mineral oils are also hailed as effective hair oils. “These oils fortify hair by improving moisture and strength and delivering nutrients and antioxidants, which protect hair follicle cells from oxidative stress,” he says. “Tea tree oil is also known for its anti-inflammatory, anti-fungal, and anti-bacterial properties.”
