I have a mixture that includes OCT, MT, MN, Rosemary and Gro-aut oil, my regimen:
I'm trying to use it all up, and take a break from growth aids, but I might stick to the oils, but this is what I do...
Mon--apply to scalp at night
Tues---apply to scalp at night
Wed--apply to scalp at night
Thurs---apply to scalp at night
Fri--apply to scalp at night
Sat--apply to scalp at night as a pre-poo
Sun--wash, but don't apply to scalp on wash days.....
So basically I apply to my scalp every night except on my wash days......but I only do this cuz I'm trying to use it up.......sometimes the night before I wash I pre-poo with my mixture and my amla and shikakai oils....HTH.....
