7. Or try peppermint oil
While there hasn’t been enough research to definitively say whether peppermint oil can aid in hair growth for sure, there have been a few promising studies. One 2014 Korean study using mice found that peppermint oil led to more hair growth than minoxidil, a hair-growth commonly known as Rogaine that’s approved by the FDA.
Beyond hair growth, the oil can be beneficial if your hair is on the greasier side. Why? It can clean and clarify hair without stripping it of its natural oils, and it balances your scalp's production of sebum, which leaves your hair hydrated without weighing it down.
One precaution: the type of peppermint oil you’re using matters. Undiluted versions (like most essential oils) can be super harsh on your skin and cause a burning sensation. If you’re working with pure peppermint oil, make sure to dilute it with a carrier oil like coconut oil, olive oil or avocado oil before using it on your skin.
8. Apply black seed oil
Also referred to as black cumin or nigella sativa, black seed oil is thought to naturally restore hair growth in thinning areas thanks to its high concentration of thymoquinone, a powerful antihistamine. Yep, antihistamines are often prescribed to alopecia patients to help regrow hair, and get this, it’s actually an essential oil.
That means it’s not thick like olive or coconut oil, and it has added therapeutic benefits. It also means that 100 percent pure, unrefined and cold-pressed black seed oil has to be diluted in another carrier oil (such as coconut or olive), because it’s too potent on its own. And when diluted, it can be used directly on the scalp to reduce inflammation, stimulate hair growth and reduce flakiness and sensitivity.
