This shampoo bar works really well. I has my doubts about how effective it would be, but it gets my hair nicely clean. It only takes a few swipes of the bar and it lathers up nicely. It is gentle on my skin and also has a gentle & natural smelling scent. The only negative I could find is that it's a slightly soft bar and tends to get a bit squishy and leave residue on the soap dish, despite me trying to keep it dry between uses. But that's a small price to pay for having a plastic free shampoo in recyclable paper packaging, that actually works and suits my skin & hair. I'd definitely recommend giving it a try. It's not cheap, but I managed to find this bar reduced to clear in Boots, just because the outer package and seal had been opened. I'll definitely be trying to budget for a replacement bar when it finishes.
