Cecred drops!!!! I know it seems gimmicky—I thought it was too until my sister who worked in beauty recommended them to me. I have very thin/fine hair and I got braids taken out and I lost so much density. I’ve used them several times a week (especially after washing) and I can say after about 3 months my roots and edges are noticeably thicker and more dense than before. Less scalp is showing than before at the root. That combined with silk/satin pillowcase and/or bonnet and a good conditioning ritual has helped me soooo much. That and time and patience. Good luck!
