Followed an ad for solid shampoo and ended up buying that and a few more bits. I've tried a solid shampoo before but couldn't cope with the transition phase. The 2 in 1 block promised no transition so thought it worth a punt. Have to say this one is amazing. Much easier to use and rinse. My thick shoulder length hair felt clean from the first use and styles normally. If you're trying to cut down on plastic bottles in your bathroom, this is the one.
