Product Information

Hearst UK is the trading name of the National Magazine Company Ltd, 30 Panton Street, Leicester Square, London, SW1Y 4AJ. She’s committed to sharing recommendations for products that truly work and make people feel confident and healthy. This plant is native to China and is a part of the buckwheat family, and it is highly revered for its hair strengthening and restorative properties. It softened frazzled hair up a treat, leading one tester to say that hers "had never looked better". In fact, it was so impressive, the majority said they'd ditch their current plastic bottle for this bar.

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. I’ve tried plenty of environmentally friendly trends that felt manageable and opted out of ones I can’t bring myself to test (reusable toilet paper is a definite no from me). We love this for those looking to upkeep their color in between real dye sessions, but it’s also great if you’re just looking to darken your natural hair without dropping too much money.The active ingredients of ginger and ginseng not only give the shampoo and herbal, fresh scent, but also penetrate deep into the hair shaft to stimulate the production of new hair, and to also revive the melanin production in your locks. You may have noticed that the shampoo bars on this list contain the same ingredient, and that is polygonum multiflora. Testers found the size and shape easy to hold and said it lathered up generously, but a reusable tin for storage between uses wouldn’t have gone amiss.

But on top of being a color deepener, this shampoo is also extremely luxurious, and will leave your mane feeling nourished, healthy, and rich in feel (not just in color). It left testers with hair that felt squeaky clean, but some noted that it took a while to fully rinse out all of the residue. If you’ve used liquid shampoos with stronger cleansing agents before, it could take a couple of weeks for your hair to reacclimatise. It will come to you packaged in a recycled, compostable box that isn’t coated in plastic, making it easily erodible and environmentally friendly.

The design was also a hit; panellists said the protruding bumps massaged their scalps and the attached rope made it easy to hang up and dry. 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.
