I neglected Porosity control for 2 years. It just sat in my cabinet. I would use it every blue moon. Now I use it more often. It saved my hair. Conditioners that use to work but stop now work again. Conditioners that didn't use to work at all now work. Even my relaxers take and last longer.
After that I bought the 32 oz from Texas beauty supply.
