I have been using this serum with other leave ins to air dry 3b relaxed hair. I have seen the other ones but i stick with the shea one to avoid protein in my products. This one seems to be the most moisturizing. My hair dries smooth, soft and fluffy without the use of heat tools.In the summer this serum helps my hair from reverting when i wear it straight.I use a seperate serum for a heat protectant but this one is my favorite for getting a soft air dry.
