Who Should Stay Away from It?
While rosemary oil is very safe, it is not for everyone:
Are you pregnant or breastfeeding? Check with your doctor first.

Do you have a history of epilepsy? In extremely rare cases, rosemary oil, as with any essential oil, is a potential trigger for seizures.
Tips and Tricks by Experts

1. Use Derma Rolling
If you want to take your results to the next level, then consider adding rosemary oil to a derma roller (0.5 mm) to get the oil to absorb deeper into the skin and scalp and be more stimulating overall.
2. Consume your way to healthy hair
Consume foods that promote healthy hair. For example, eggs, leafy green vegetables, avocados, and nuts.
3. Don’t forget to stick with it
“Don’t expect miracles overnight!” If everything is perfect, hair will grow only about 0.5 inches per month, and that does not include any shedding. Just stick to it!
4. Avoid toxic products
Try to avoid any potential “destructive” products out there. Watch what you wash your hair with at the beginning. Sulphates, parabens, and alcohols can wipe out all the good rosemary oil did for you.
