yes i always seal. i mix oil and condish in the palm of my hand, rake it in and once its not dripping wet, i seal with a different oil as i used with my condish, then after an hour or so i do my scalp message. this has worked GREAT for so long.

my hair: 3c, high porosity, high density and coarse hair (i think i finally figured that all out)
my hair loves conditioner only styling!
my hair goal length is bra strap length when curly.

I also blog about my hair journey, please feel free to read and comment/ask questions
