I have hip length hair that is naturally textured (wavy & some curls) which is naturally dry & highlighted.
I personally can not live without jojoba oil for the middle dry sections and the ends. Jojoba is very similar to human sebum which is natural scalp oils. I love how light it is and you can mix it with all sorts of Essential Oils (EO) like Lavender.
For hair growth I mix a few drops of Basil (Sweet not Holy) with jojoba oil and use it as a massage oil for the roots. You never want to use Essential Oils directly on the skin>
Coconut oil is great for naturally curly/wavy hair that is damaged. Some people swear by caster oil, but I find it too heavy and oily.
