If you've been on TikTok lately, you've seen the rosemary oil trend. But unlike most viral hacks, this one has serious science behind it.
A 2015 study compared rosemary oil to Minoxidil (Rogaine) and found that after 6 months, both groups saw equal hair regrowth. The difference? Rosemary oil had far fewer side effects like itching.
We tested the most popular rosemary hair oils to see which ones are worth buying.

How Does It Work?
Rosemary oil contains Ursolic Acid, which increases blood circulation to the scalp. More blood flow means more nutrients delivered to the hair follicle, which stimulates growth and prevents hair loss.
It also acts as a DHT blocker, helping to prevent hormonal hair loss.
