Coconut Oil: (My favourite) Great protectant for hair and skin. It's very penetrative and light weight, it softens and conditions my hair. It's also great for pre-wash conditioning, aka pre-poo. It also mimics Sebum but it's not as close as Jojoba oil.
Jamaican Black Castor Oil: THIS! Stimulates growth. Although it's quite thick, I mix it with other oils and it makes my hair soft.
Shea Butter: One of the first oils I started using, I used it for everything and I still include it in my oil mix today. It also makes my hair soft and it's great for sealing in moisture. It also contains sufficient SPF to protect your hair from UVS.
Jojoba Oil: This oil is great for your scalp because it's closest to the natural oils that our hair produces called Sebum. This means it is easily absorbed into your scalp and is great for treating numerous scalp issues.
Tea Tree Oil & Eucalyptus Oil: Both have anti bacterial and anti fungal properties. Eucalyptus promotes ceramide production so it increases elasticity as well. Tea Tree stimulates the scalp and this can also promote hair growth.
Almond Oil: This oil has a lot of fats that are great for fighting dry, brittle hair.
Oils I haven't used but would like to try are Argan oil, Grapeseed oil, Pomegranate seed oil, Avocado oil and a bunch of others but let me know, what are some of your favourite oils to use and why?
I don't claim to know all about the oils I've listed and I definitely haven't listed all their benefits either so it would pay you to do some of your own research as well and find out what works for you.
