Years of testing shampoos has taught me two things: 1) No matter your hair condition, there's a shampoo category to help (see: dandruff shampoos, mild shampoos, shampoos for dry hair, etc); and 2) Shampoo bottles create a lot of waste. Like, a lot. Of course, that’s no reason to abandon shampoo completely. But it is a pretty good reason to start using shampoo bars—aka soap bars for your hair—instead.
The best shampoo bars aren’t just more environmentally friendly than liquid shampoo, they’re also more concentrated than bottled formulas, which are diluted with water, so you can get way more bang for your buck (depending on your hair type, length, and how much lather you prefer). Some bars can last up to 80 washes, which equates to three-ish bottles of shampoo! Not convinced yet? Well, after testing the best shampoo bars out on myself, I can confirm that they're also super travel-friendly (no accidental spills!), easy to use, and totally beloved by reviewers who can't stop raving about them.
