I would like to go longer without washing my hair. Currently, I can only go a day; for instance, I will wash my hair Tuesday, and not Wednesday, but again Thursday. I only shampoo the roots, however, I have not shampooed the length for about a week and counting . I think I will shampoo the lengths twice a month. The problem I have is that my hair gets greasy even in that second day. Part of that probably is that I apply a leave-in conditioner, but I apply very little, just enough. Soo.. I don't know XD
