This is the worst shampoo I have ever used and downright dangerous. Used for 2 weeks with hair fall in shower getting progressively work. Stopped using it, as it was only change to my routine. In space of 2 weeks it has completely ruined my healthy hair, drying it to straw, and have been left with a very noticable bald spot on top of my scalp. AVOID AT ALL COSTS!!
