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.

Our Lipid-Retention formula seals moisture during the wash — one step and done. No conditioner needed.

Impressed with the results

I have been using shampoo bars for more than 5 years now and this one truly lives to its name. My hair feels clean and soft without the need of conditioner, plus the scents are not too overwhelming when the hair is dry.
I tried the mini kit which was not expensive compared to the actual stem but hopefully it actually lasts more than 3 months as they say. I’m excited to try it!

I love the body wash and shampoo. I just wished it had some suds.

Not a fan

It was not easy getting a lather and left my hair feeling flat/no body after a week of use.

Overall Very Good Products

I like the aloe tea tree & santal oak smells and textures. The little bit of grit reminds me of a nice body scrub. The body wash bar doesn’t last as long as advertised (at least for me), but the tea tree shampoo bar has been great for my scalp/dandruff and has lasted as long as I would expect. I think the cardboard grips hold up (don’t get soft or waterlogged) and work well. Love that there is no plastic involved. Would definitely recommend.

Love This Shampoo

I started using this product about a year and half ago. It is the best thing I did for my hair. Not only does it do good for my hair, but this product has also saved my wallet! I have only bought 4 bars since I started using it. I even gave one of the 4 to my daughter to try and she loves it too.

Simple Solutions

I've tried lots of brands of bar shampoo and conditioner, but they always end up mushy and fall apart. I have been using Swell labs for a month now and I love how the product is designed. My hair feels healthy and the cap and base system work great.

I’m so glad I found SWELLLABS!

I’m so glad I found Swell Labs! I’ve been trying to reduce the amount of plastic I use, and my hair has honestly never felt better. It took me a few washes to get used to using a shampoo bar, but the results are absolutely worth it. For my hair, I’ve found that lathering twice works best, and my hair stays clean for almost an entire week!

I’m allergic to many products, but I haven’t had any issues with this brand. Their scents are lovely and gentle without being overpowering, and I also love how incredibly soft the body products leave my skin. I’m officially a fan!

The concept is great

The idea of this is great but as soon as I took it out the packaging & tried to open it up to smell it, it was breaking apart. Small pieces were falling off so I shoved it back in the package because it was making a mess on the floor.
