Phase #1

Selective Cleaning

Most shampoos are blunt instruments, stripping away dirt and essential oils alike. Stem’s Lipid-Retention™ technology cleans with engineered precision. It targets buildup while preserving your hair’s protective lipid layer, leaving the cuticle smooth and the moisture barrier intact.

By keeping the cuticle sealed naturally, we eliminate the need for heavy conditioners to smooth it back down later.

Phase #2

Hydrated, Not Coated

Traditional conditioners mask damage with synthetic films that eventually block moisture. Stem hydrates from within. Because Phase #1 preserved your cuticle, bio-active cocoa butter locks hydration inside the strand, leaving you with weightless, residue-free softness.

Because there is no film blocking the surface, your hair is now primed to absorb vital nutrients in the final step.

Phase #3

Bio-Available Repair

You can’t feed hair that is suffocating under silicone. Because Stem leaves strands uncoated and breathable, our restorative proteins and nutrients are finally able to penetrate the cortex. They fill structural gaps to rebuild density and elasticity from the inside out.


Stem isn't a cosmetic mask. It is a health treatment that makes hair stronger with every wash.

A couple of tips

I’ve already written a review for this shampoo bar (I get the unscented) but wanted to come back to offer a couple tips. I have been using gentle shampoos for years, but after using this bar a few times I experienced a short period of time where my hair got oily pretty quickly — a day or sometimes less after washing, mostly on the under layers. But I stuck with it and now my hair stays clean for days. Some other things that have helped is shaving the beeswax down as far as the cap allows (about 1/2”) so it doesn’t come into contact with my hair or scalp and also applying a bit of something salty to my roots — I highly recommend The Magic from Sparrow for Everyone. It’s intense but if you take the tiniest bit and mix it with water it helps spread it more evenly and reduce the over-dry feeling I sometimes get with it. Still the best shampoo I’ve ever used! Liquid or bar. I love that it’s one step and I don’t have to spend so many minutes rinsing conditioner out of my hair

Convenient

I love that it's clean, easy to use and travel with and no bottles to deal with. I prefer the clean bar, , no fragrances.

Pure goodness

I have used the Swell bars for the last couple of years. I recently needed to reorder and decided I wanted to try the Swell Clear. This one is great. I feel that it lathers up better. Some scalp issues have cleared up and my hair feels great.

Incredible Product!

I have dry, coarse curly hair that has been going grey for the last ten years. I have tried so many different curly hair products that all felt like they were either leaving behind a lot of buildup, or were stripping the little oils I did have.

I would say it took about 3 or 4 washes before I really started to feel the difference. I use the Lavendar Romarin for my greys and I love it. So soft, my hair is shinier that it has been in a very long time, and it stays curly and hydrated longer.

I could not recommend this product enough. I don't know if there is actually a difference in the bars besides the scents, but I did think the Santal Oak was more drying than the Lavendar.

Amazing product.

Started using this a couple months ago, never is it advertised - but my hair has for the most stopped falling out. Bought some for my daughter and my son, they had the same results. Wish I knew about this like 10 years ago!

I’m a convert

I have tried other shampoo bars and have discovered that my Swell bar is My favorite. I love the convenience of one product. I also appreciate the travel aspect of this bar. Mostly I love this product because it doesn’t have any plastics, which is something I work very hard to avoid. To be honest, the bar takes getting used to. It doesn’t suds up right away but when it does, the suds are great. The final rinse leaves my hair a bit difficult to comb, even when I leave the shampoo on for an extra few minutes (the suds disappear) as recommended. Bottomline for me is the way my hair feels afterwards. I love the softness and manageability I get from this shampoo. It’s a keeper.

Great Product

I was pretty skeptical about this, to be honest, but I love the idea of using less plastic and simplifying my routine. The shampoo bars are truly awesome! The only drawback I had is, it takes my hair a long time to get wet but I just have really fine hair so nothing to do with the shampoo. Once your hair is thoroughly wet this makes a really rich lather! I feel like all the residue from years of other shampoos has been stripped off my hair and it is so shiny.

Easy peasy

I like the light lather that rinses out so quick and easy. Haven't used it for very long, but so far I will probably keep buying it.

Slow shipping, good product

I’m enjoying the shampoo and the body wash so far. The shipping was very slow.
