this looks like a great start! i have a massive ever growing collection of oils all tried on tested on face, body and hair. I too have a nice oil mix that i message in my scalp every night. this helps with healthy hair growth. i really think that my mix works for me: rosemary, peppermints, vit E oil and my carrier, or "base" oils are half argan and half evening primrose oil.
do you really message your scalp with it? i put it on my finger tips, rubb then together and give my self a nice message. i start at my crown, then i put more oil on my finger tips and work my way down. i add more oil to my finger tips maybe.... 5 or 6 times.

my hair: 3b, high porosity, high density and coarse hair (i think i finally figured that all out)
my hair loves conditioner only styling!
Oils and my own procuts are my hairs best friend
my hair goal length is bra strap length when curly.
