grape seed oil is great, aprecot oil, argan oil is good as well. all of these you can use to seal and to add to a DT. you have to try different oils your self, cause every one reacts differently to different oils. try light oils first.
my hair: 3c, high porosity, high density and coarse hair (i think i finally figured that all out)

my hair goal length is bra strap length when curly.
