Product recommendations? Current line-up helped before, not anymore. Please see below :)
I have type 3b hair that is medium porosity, thick, and high density. Like many people I have an extremely dry patch in the back of my hair. I chopped off my hair over two years ago and have been growing it out with minimal heat styling minus the occasional flat iron to check length (I can count on one hand how many times I use it in a year). I have been using the shampoo and conditioner from Shea Moisture's Shea butter line for two years and the deep conditioner from the 10-in-1 renewal system for about 8 months. This combination helped for a bit, but now I'm back to this extremely dry patch.
