Having a hard time remembering to apply your hair serum? Allow us to introduce you to habit stacking, a simple and effective technique. All you have to do is take one of your existing habits, like brushing your teeth or applying your skincare, and stack a new habit on top, such as applying GRO Hair Serum. By habit stacking, you can easily develop new habits and enjoy noticeable results with your GRO hair serum. #vegamour #habitstacking #habitformation #hairserum
