I use herbal essences hello hydration as well! Isn't it amazing??
however, it is conditioner so i wouldnt recommend using it as a gel. I dont even use it as a leave in because it is very thick. so my routine is...
Herbal essences shampoo
Herbal essences conditioner (ice queen method)
Squeeze excess water out of hair with a tshirt
Scrunch in my leave in (neutrogena triple moisture leave in is wonderful)
Scrunch in my mousse (suave professionals captivating curls is absolutely fantastic)
Seal with some almond oil
Let air dry and go!
Now, my products are not CG because that method did not work my hair as it does not work for everyone. However, I do follow cg methods such the icequeen method, scrunch n pump all my products, and occasional plopping.
