Well..I don't know if my hair is porous or not..but YEARS ago I got very badly done highlights and no deep conditioning helped the dried out hair..

All I know is my hair is dry, and breaks easily..after brushing I can still rake out strands of hair

Which was why inliked aubrey..I had seen less hair falling out and breaking, but I didn't like the way the shampoo made my hair feel..well like rubber o3o
