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.

Love this Shampoo!!

I really hesitated with ordering this shampoo since I have had no luck with other products. This product certainly delivers. My hair is fine with a course texture to it. After a couple of weeks of use my hair feels soft and manageable. I find for me I do not even need to use a conditioner. Thank you Swell Labs for making this product!!

Good soap

The shampoo has an odd consistency that I'm not totally used to yet, but it cleans my hair well and seems to condition it ok enough. My hair doesn't feel as soft as I'd like it to.

The body wash has a great texture, and I really enjoy using it. My only complaint is that now I am almost out of it (lol).

We're impressed

I'm still exploring, but it's definitely impressive. I have long thick hair that is starting to grey, so I'm active to find something that will help it relax and less frizz. This is slowly helping my hair, but for my husband he loves it! He wouldn't have tried it without my prompt and now he's noticed a difference he enjoys. He's still getting the hang of it, to lather. ;-)

Love it

I was skeptical at first but wanted to stop dumping chemicals over my entire body everytime i showered . I have been using swell for a year and a half now. I have only purchased 3 in that time because they last ! So easy for traveling and my hair is so much healthier now

Good

The shampoo is good but I not good enough to not need conditioner too. If used alone I end up with an unmanageable wad of hair. With the addition of a bit of conditioner my hair turned out quite soft. So a matching conditioner bar would be great.

100% sold, this is amazing!

I’m stunned at how well this works. I have long, wavy, frizzy hair and I don’t use any extra conditioner. I’ve been recommending this to everyone and will be buying a few more to make sure I never run out. It stays completely solid in the shower with no mushy mess like other shampoo bars. I’m in love!

I took it on vacation and it was so compact, required no special packing and worked like a charm.
