비오틴 퍼플 토닝 샴푸 & 컨디셔너 바 – Paradise Beauty Company

The lather on these bars is richer than I expected for a solid shampoo, and my highlights have stayed a cool, icy blonde for three weeks now. I love that the biotin is built right in, so my hair feels thicker even after the toning rinse.

I've been on the hunt for a sulfate-free purple option that doesn't dry out my highlighted ends, and these bars finally nailed it—the biotin in the formula leaves my hair feeling thicker even after rinsing. The solid format is also a game-changer for travel since there's no liquid to leak in my bag.

The bar lathers up way better than I expected for a solid shampoo, and the purple tint really does knock out the yellow in my highlights. My hair feels thicker after washing, which I’m guessing is the biotin, and the conditioner bar leaves it soft without that heavy residue.
