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.

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!

Trial Opportunity

I originally came across an ad in social media for this company and found the offer to try both the shampoo and body wash and only pay for shipping.

Since I was already considering shampoo bars and an alternative body wash I decided to give this company an opportunity.

We were pleasantly surprised with the product and are definitely considering switching over once the remainder of our normal products runs out.

We opted for both in the clear options. The shampoo leaves hair soft while the body wash does its job as well. I’m happy to have unscented options and this product has an environmentally friendly goal.

I’ll never ship water-based shampoo and conditioner again.

I am very impressed with this shampoo/conditioner solid product. I’ll never ship shampoo and conditioner that are mostly water again. My hair looks great, and I actually feel like I’m getting a massage of my scalp when I’m applying the solid.

Awesome

This stuff really surprised me! I love the concept since I live on a boat and have minimal space. I really love the shampoo condition bar it smells lite and leaves your hair so soft. It takes a bit to get used to not having all that weight from regular shampoo a conditioners on your hair. My hair feels so healthy and flowy now I use a lite leave in conditioner after the shower since I’m prone to static hair. I LOVE THIS STUFF! The body wash bar is okay.

Great product and customer service

We switched to Swell Labs from a liquid organic shampoo and conditioner that arrives in plastic (with no refill option). While our primary reason for switching was reducing our environmental impact, these bars have been great for the entire family, including young kids who are happy to wash their hair now by themselves and no longer cry (except every now and then for dramatic effect). My hair is voluminous (I have a lot of it), so the bigger thing for me is extending time between washes as my hair can feel oily quickly. With these bars, I can wash my hair every third day instead of every other day. We all love them, and the customer service is fantastic. Shout out to Cindy! They are great for travel too.

Surprised how good it is!

I have very oily, very fine hair and almost all shampoos weigh it down. I have never had such a drastic result after one shampoo: full, light hair that is truly cleansed and NOT weighed down. Absolutely love the tea tree and will order the full size after I use up my current shampoo. Highly recommend!

Very Impressed

I, like you, saw ads on my feed. I looked into reviews and ingredients. I finally saw the option for the mini duo for just the cost of shipping. Figured worth a shot. I chose the aloe tea tree shampoo bar and coconut inoki bodywash bar. When I tell you this 45 y.o. man has Farrah Fawcett locks after a shower...I mean it. My thick grey/blonde hair that I've grown out a bit is so light and full of body after a wash. It cleans my hair of oils/sweat and leaves it so soft and weightless. The bodywash is also very good. Leaves my skin feeling clean and hydrated, not stripped and dry. The vanilla scent is very subtle but enjoyable. The body wash bar doesn't seem to lather as well, maybe it's me? You do need to use several passes to produce a little bit of soap suds. Still, overall the products are great, my hair looks/feels great and I look forward to trying my next order. Well worth a try!

Best shampoo bar I have used

I have only see the sample sized shampoo bar a few times and I can already tell it works better than my expensive bottles of shampoo and conditioner. I have used other shampoo bars and they worked ok but always ran out really fast and would get mushy towards the end. I like everything about this one. It takes up less space in the shower, easier to pack when I travel, smells great, and more importantly it works great on my hair. I will definitely be ordering my more when my sample starts to get lower.
