ive just started using the morrocanoil mousse as well, i really like it. i use my leave in condish and oil first, i kind of rake it in my hair, after ive showered/washed it. i i use one full pump flip my hair unside down then i work the mousse in my hair. i wet my hands with cold water and scrunch a bit.
it really gives me nice curls.

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.
