87% of Users Stop Using Conditioner by the End Of Week 2

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.

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.

Finally took the plunge!

I have been looking at shampoo bars for some time but was never fully convinced that they lasted as long as the claims and therefore could not justify the price. But they really do last! I'm two weeks into using the shampoo mini and am only now seeing it go down. I have long thick hair and wash it on an almost daily schedule. I do also love the holder and how it keeps it all together. It's taken a little to get used to not having so m that silky smooth post conditioner feeling directly after a shower but I will say my hair still looks and feels great once dry and I've noticed a lot less molting!

Light Hair

I have long, thick hair and this stick works great for me! I wash my hair about once a week. I like to use different shampoos and conditioners regularly. This stick used alone is great and leaves my hair so light and clean. Every other wash I use a clarifying shampoo, and a conditioner maybe once a month. With this stick my hair feels clean and light; and is full of movement.

I am truly blown away!

I have always had ALOT of hair. And now my daughter does as well. I have been using different shampoo and conditioner bars but have never found a conditioner that did any good. I am so glad I gave the Coconut Hinoki a try. We only wash our hair once a week and have only used it twice but I am already blown away! I don't know how you did it, but bravo. I'm telling everyone I know about this product. Please do not sell out to when the big companies come with their big checks to buy you out. We need more companies like this one.

The Champion of Shampoo/Conditioner Bars!

I have used other shampoo bars and conditioner bars in the past with very disappointing results. The shampoo bars would break apart and the conditioner bars were so slippery and hard to hang on to. I'd always end up throwing away product. Swell Labs has defiantly raised the bar! I like that it is both shampoo and conditioner in one product. It is easy to handle with wet hands and the best part, it doesn't break apart!!! I ordered the Santal Oak & the Aloe Tea Tree and both work wonderful for my hair needs. My hair is very healthy, shiny and smells great! These products do exactly what they say and I will be a life-long customer.

All other shampoo is dead to me!

I love this product. As advertised, it smells great, outlasts several bottles of the regular stuff and leaves hair feeling clean and healthy. I’m a convert!
