Most shampoo and conditioner come in liquid form, but for traveling purposes, environmental friendliness, and all around convenience, it's hard to beat a shampoo bar.

For the unfamiliar, shampoo or conditioner in bar form can seem strange. But just like bar soap, all you gotta do is rub it into a thick lather and work it into your hair. Super sudsy, super easy. Here are some of our current favorites.

Lush has an amazing range of shampoo and conditioner bars, but their Godiva Solid Shampoo is my absolute favorite. $9.25, and it makes my hair super soft, clean without being stripped of all life, and potently scented of jasmine.

A new brand on the market, Seed Body Care, is harnessing the power of the grapeseed for their line of soaps, lotions, and yes - shampoo bars. Their Grapeseed Enriched Conditioning Hair Shampoo Bar is both invigorating and nourishing, and the slightly-scrubby texture feels great on the scalp!

Next time you hit up your neighborhood Target, don't skip the beauty aisle! Tar-jay has stepped up their hair, body care, and makeup product selection dramatically. One Bath and Body is among their latest offerings, and this brand is committed to natural beauty, eco-friendly products, and recyclable, plastic-free packaging. Their Hair Biscuit shampoo and Hair Boost conditioner come in embossed aluminum shower tins, and are so ideal for slipping into your gym bag en route for a workout.
