This powerful herb has taken the hair care area by storm – and for good reason. A question that leaves people scratching their heads is, “how long should I leave rosemary oil in my hair?” Let’s take a deep dive and get the answer backed up by science, experts and real users.
What is Rosemary Oil? And Why Is It So Popular?
Rosemary oil is an essential oil which is derived from an aromatic herb, Rosmarinus officinalis. Rosemary oil stimulates blood flow to the area in which it is applied, and when applied to the scalp is especially powerful by enhancing hair growth, strengthening strands of hair and aiding in dandruff.
Fun Fact: According to a study done in 2015, published in SKINmed Journal, rosemary oil was found to be just as effective as minoxidil (Rogaine) at enhancing hair growth after 6 months of use, without the itchy scalp side effect!
How Long Should You Leave Rosemary Oil in Your Hair?
There is no one-sized fits all answer, but here is a breakdown based on hair type, outcome and method of use:
1. Quick Scalp Treatment (15 to 30 Minutes)
Best for: Those who may have a sensitive scalp or are first-time users.
How: Mix with a carrier oil (coconut or jojoba work well) and massage into the scalp. Leave the mixture on for 15 to 30 minutes, and rinse out.
