I was introduced to this while in hospital and couldn’t wash my hair at all. I have to say that this was my saving grace. I hate feeling dirty and could bath my body but was not allowed to wet my hair and the spray shampoo definitely did the job it was meant to. A very hard working product in a deceptively simple bottle. This is a product I actively recommend to everyone. You have to have at least one in your home for those unexpected emergencies? Or for when you just do not have the time! I didn’t really like the foam one though.
