The oil from the neem tree has been used in traditional Ayurvedic medicine for thousands due to its healing properties. In Hindu texts, neem is referred to as the plant that “cures all ailments and ills” and has its roots in the Sanskrit word meaning “bestower of good health”.
Neem oil is a potent source of beneficial oils and is astringent, antibacterial, and antifungal. It also helps to boost circulation and repels lice and mites.
Neem oil can be beneficial to the skin and hair, and is often used to rejuvenate hair growth as well as to combat a variety of problems of the scalp including psoriasis and eczema, scalp irritation, and dryness and dandruff. Massaging neem oil into the scalp before bed or a few hours before washing can make a big difference in the overall health of the scalp.
Neem oil can also help with the overall condition of the hair, since neem is rich in essential fatty acids, which help to nourish dry and damaged hair.
The only drawback to neem is that it has a slightly odd or medicinal smell (it personally reminds me of peanuts). If you dislike the natural smell of neem, you can add a small amount of essential oils to the neem oil before applying to the hair (which will also enhance its benefit). For dry and damaged hair, try sandalwood or geranium oil; for encouraging hair growth try atlas cedar, juniper berry, cedarwood, or lavender; for oily hair and scalp try patchouli, rosemary, or ylang ylang.
One more note about neem oil- at room temperature (especially when it’s on the colder side) neem can begin to turn solid, so when you open a bottle, you may see tiny chunks of oil on the dropper. It doesn’t mean there’s anything wrong with the oil, it’s just what it naturally does. If you find your neem oil beginning to solidify around the dropper or cap, just run the bottle under warm water for a minute and it should be fine.
