Yes, rosemary oil may help promote hair growth. Some studies suggest it can improve scalp circulation and stimulate hair follicles. In one well-known study, rosemary oil performed similarly to 2% minoxidil for certain types of hair loss after several months of use, with less scalp itching reported.
Potential benefits:
- May support hair growth and thickness
- Can improve scalp health
- May help reduce hair shedding in some people
- Contains antioxidant and anti-inflammatory compounds
How to use it safely:
- Dilute rosemary essential oil with a carrier oil (such as coconut or jojoba oil).
- Massage into the scalp 2 to 3 times per week.
- Do a patch test first to check for skin irritation.
Keep in mind: Results are not guaranteed, and noticeable improvements typically take several weeks to months of consistent use. If hair loss is sudden, severe, or worsening, it's a good idea to consult a healthcare professional.
