I was doubtful that I could get smooth results from a rollerset because my hair is so coarse. I was wrong. I did a "ponytail" rollerset by putting my hair in tiny ponytails, getting the roots as straight as possible. I combed thru each tiny pony with a homemade leave in of water, HSR, SAA and shea butter then put on the ponytail holder. I rolled the length of the hair on a magnetic roller. Sat under the dryer for 1 hour and let the rest air dry. In the morning I went over just the roots with a little Sabino and Chi silk infusion and flat ironed -- just the roots!
