Product Information

Whether you want to nourish damaged hair or help boost volume, here are 12 of our top solid shampoo bar picks to help kick off your cleanse.

Perfect if you work out regularly, this bar helps balance oil control with lightweight moisture thanks to its blend of zesty lime and orange oils and moisture-attracting humectants (ingredients that attract water to skin). Heads up (subjective): after a few weeks of use, I did feel a little itching at the base of the neckline where the hairline is. This boosted the vibrancy of our testers’ colour-treated strands, leaving everyone content with the deep clean it provided. Unlike regular hair color, which contains dangerous chemicals, this shampoo bar is composed entirely of natural herbs.Thankfully, the hair care world seemed to grow up alongside us, having a shampoo fit for all of our growing hair concerns.

Made with all natural ingredients and noni fruit essence, this shampoo will hydrate and nourish your scalp, making it a great pick for those with allergies or sensitive skin. Shampoo bars still produce the foamy lather we all know and love, and they're formulated to be less stripping than traditional soap.This bar eliminates waste but still managed to give a thorough clean, leaving testers with softer, nourished lengths. If it doesn’t explicitly say on the bottle that it is, chances are the product has been tested on animals. This makes it a great pick for those maintaining brunette color in between salon visits, but we love it for those who already dye their hair using henna to begin with. That’s why so many stylists and hair experts warn you to stay away from using shampoos with ingredients like sulfates, alcohol, parabens, and silicone; they’ll mess with the look and feel of your hair over time.

It depends on the formulation and how you use one (particularly when it comes to washing it out properly). If you’re looking for ways to reduce your plastic waste, these solid shampoos can be a good choice in our experience. The panel found they didn’t have as many knots in their hair as normal after using it, and our lab analysis found it extremely effective at smoothing. As for longevity, this single shampoo bar can last you up to 3 months (or longer), which can seriously reduce your carbon footprint in at least one part of your beauty routine. However, if you experience hair loss or your scalp is itchy after using your shampoo, chances are it contains allergenic ingredients.This product doesn’t focus on fixing your strands, but rather healing the damage done at the root to bring life to current growth, and stimulate new growth. If you have damaged locks, and are looking to deepen your color without additional damage, this shampoo bar will be your new best friend. It didn’t crumble, managing to keep its shape throughout the entire test, and impressed all testers with how refreshed it left scalps feeling.

You may have noticed that the shampoo bars on this list contain the same ingredient, and that is polygonum multiflora. This classic brand might not be the first that springs to mind when you think of shampoo bars, but our testers rated it highly. If you like to keep your shower regime short and snappy, an all-in-one bar speeds up showers and takes out the fuss of having lots of products.If you’re looking for a more sustainable swap for your liquid shampoo, shampoo bars could be the way to go. Whenever you wash your hair, you’re not only rinsing away grease and dirt, but you’re also opening your hair shaft and allowing the follicle to absorb all the ingredients in your shampoo. Most were happy with the condition it left their hair in, and it was also a top pick for those struggling with frizz. My only gripe is that the bar lasts about a month with daily use as opposed to the two months I got out of my liquid shampoo.
