If you've ever tried washing your hair with a regular bar of soap, you may cringe at the idea of bar shampoo. But don't let that squeaky, tacky bar soap experience turn you off bar shampoo, which is specially formulated to be used in your hair. There are some surprisingly moisturizing bar shampoos that can be even better than liquid shampoo.
There are a few benefits to bar shampoo: less packaging means it's eco-friendly (not to mention TSA-friendly, according to the TSA website), and it's harder to accidentally get too much on your hair and waste it. While these bar shampoos can seem a bit more pricey than your average drugstore shampoo (though they're still relatively cheap at under $20), they tend to last longer than liquid shampoo (some producers advertise up to 80 washes), so you're getting more bang for your buck.
But as someone with curly, fine, and somewhat persnickety hair myself, I was initially skeptical of the idea of bar shampoo. My hair demands to be moisturized with the nectar of the gods, or it will frizz out and become a hellish, Boschian horrorscape. Luckily, I've found a bunch of bar shampoos that promise maximum hydration for your hair, with gentle ingredients and high ratings from buyers. And maybe it's just because I'm a bit hungry, but these bar shampoos look surprisingly delicious (disclaimer: don't eat shampoo, no matter how much it looks like a luxury dessert).
