Looking for a darkening hair wash that is both gentle and effective may seem like an impossible task, but thankfully Chenri pulled through with their instant hair coloring shampoo. They judged them on ease of use, how well they cleaned hair, and how good they were at adding moisture and smoothness. Because of its natural composition, this kind of shampoo can work on everyone. However, if you experience hair loss or your scalp is itchy after using your shampoo, chances are it contains allergenic ingredients. Instead of emulsifying the shampoo in your hands like you would in the liquid form, you’d just work up a lather like it was a bar of soap, and then transferring the suds to your hair, or by rubbing the bar against your hair directly.
How? By penetrating deep into the scalp and working to heal your hair at the source. 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’re making the switch to a bar shampoo for the first time, we do have to warn you that there is a bit of a transition period. As someone who worries about the current climate crisis, I’m always on the hunt to make my routines more sustainable. 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). But when I saw a shampoo bar for the first time, it piqued my interest. I took a look in my shower to see how big of a difference this would actually make and saw seven plastic bottles lining my tub. It appeared my environmental impact was building up like damage to the ozone layer. I knew then that I wanted to make the switch to a plastic-free solution. If you’ve dyed your hair dark from a lighter shade like blonde, you may want to use a dye depositing shampoo to achieve the best results. On grey or colored hair, it has a less severe impact. On the other hand, it does not endure as long as permanent dyes.

Vegan, Leaping Bunny certified, with no sulfates, parabens, dyes, lanolin, talcum, phthalates or silicones CLAIM- lasts up to “over 80 washes” depending on how you use it, or “at least as long as a 16 oz bottle” This shampoo darkens natural light and chemically colored hair and modifies its color. Notably, the natural extracts operate on your hair, depositing a layer of colorful pigments around it, your hair shaft, and dyeing without harming the hair structure. Our preferred method is to lather up the soap between our hands first and then apply to our hair, before rinsing it off with warm water, but some brands recommend wetting the bar and rubbing it directly into hair from scalp to ends.
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). 6. Polygonum Multiflorum Shampoo Bar Also plant-based, including all natural ingredients like polygonum multiflora, ginseng, and coconut oil essence, this shampoo works overtime to deliver some serious darkening factors to your hair. The hair darkening shampoo bar is suitable for all genders with all hair types, except for curly hair. To make your bar last as long as possible, try storing it in a tin or soap box and keep it dry in between washes to stop it from crumbling. Some now even come with a handy rope built in to allow you to hang it dry after use. Genius! If you’re looking for ways to reduce your plastic waste, these solid shampoos can be a good choice in our experience.Our panel of 650 trialed 45 brands of eco-friendly shampoo bars for four weeks to find our winners. In addition, because this shampoo stays on top of your hair instead of being entirely absorbed by it, the color will last for a few shampoos before gradually fading away till rinsed away.
