Slide 1 of 3

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.

Amazing shampoo!!

I have the hardest time finding shampoo that actually cleans my hair. I always want it to be natural, but it’s so hard to find an effective one. This is amazing!!!!!! It’s actually cleaned my hair, and made it soft! I can feel a difference after only two washes. Definitely ordering more!!

Sensitive Skin!!

For me, hypothyroidism & anemia have caused hair loss by handfuls. This tea tree with rosemary has healed my scalp and helped lymph function. I also use a liquid iron supplement to facilitate hair growth. Best clean ingredient product I have found. Thank you Swell for clean, healthy products that actually WORK! Love and light, I had no idea that my hair had curls!

Does what I need it to do; it seems like it’ll last a long time. Smell is pleasant and noticeable without being cloying

😍

Absolutely amazing the body wash made my skin so soft. I don’t think shampoo conditioner in one works for me. But it’s working good in my hair paid with another conditioner bar.

Love the aloe body & hair bar

Been with you like 2 years. I tried so many other bars. I cant believe a crunchy 2n1 beat out all the other designers. The only complaint I have is I wish you would get some new scents maybe two that rotate twice a year or something ? I’m so tired of the green and the purple one i’ve actually started getting a clear one and then just scenting it myself.
