Oi Shampoo

The gentle shampoo coddles hair with a blend of moisturizing oils, leaving it soft and clean but not stripped. It has a hefty price tag for a product you use for a few seconds and wash down the drain, but a little goes a long way. It’s also sulfate- and paraben-free, and works well on nearly all hair textures (though it may be a tad too thick for very fine strands).
