"I've been using solid shampoo for a year or so, and I find it so much better than the normal bottled version. It's way better for the planet, it's easy to travel with and my hair is thriving. It took a couple of weeks for my hair to get used to it, but now it's healthier and lasts longer between washes. I keep mine inside a plastic travel soap container, and if I'm going away I can cut the bar into halves or quarters to make it even more portable. It's a little pricey but it lasts FOREVER, and is totally worth the cost. " – Jemima Skelley
