Causes major HAIR LOSS !
I lost half of my hair after using this shampoo. I thought if I continue using maybe slowly it will get better but NO. I have now stopped using this shampoo and in 2 washes I can see the difference. Please DON'T use this shampoo if you love your hair.

Don’t Buy
The product is great! The bottle is absolutely awful! This is a travel sized bottle and it leaks. I thought maybe it was the pressure of the plane, but when I took a train and it leaked again, I knew it was a bad design for the bottle. So far, I’ve lost about 1/4 of the product because it leaked out. They need to redesign their bottle to keep the product in there. The conditioner, which is thicker doesn’t leak.
