#1: More than one porosity
Is it possible to have more than one porosity type? I did the water test on two strands. One had been highlighted with about two inches of growth. Yes, I need to do something about that but thankfully curly hair covers roots well. The other hair was from around my neck and wasn't colored. The colored part of the first strand sank and the root section floated. The one from my neck is still floating. Does coloring hair change porosity and how do you maintain and care for hair with two diff porosities? Help!
