I only use penetrative oils and I use different oils for hair and scalp. I infuse an array of vedic herbs.
For my scalp massaging oils I use; jojoba, sesame, castor and emu, These oils penetrate deep into the skin.
For the hair I use; coconut (bind protein to the hair), Avocado (binds moisture) and castor.
There are others but those are the main ones that I can think of right now
