I've tried many different kinds of shampoos (liquid, bars, and even dry shampoos). I switched to shampoo bars at some point as 1 - it removes plastic waste, and 2 - it smaller and easier to carry around when traveling. Now, I don;t know if its the forumaltion or what but after trying several brands, they weren't really that good. Enter "The Powder Shampoo". I was skeptical at first, especially that the price isn't that cheap, but I wanted the change. It ticks all the boxes of what I want in a shampoo. It smells great, it removes plastic consumption + its recycleable and refillable, it's super light weight - great for travel, it's vegan and cruelty free - very important!, it makes my hair awesome and lively (and somewhat thicker too). So yeah, best shampoo so far. Highly recommended.
