Customers praised these bars for excellent lather, pleasant scents, and leaving hair soft and clean. Many noted "my hair has never felt cleaner" and appreciated the eco-friendly, plastic-free packaging. However, some mentioned the conditioner bar is too small for long hair, runs out quickly, and can be difficult to apply. A few found certain scents overpowering or experienced dryness.
- The shampoo cleans so well and lathers like crazy! And the conditioner works really well!!
- Better than any other product I have ever used - genuinely!
- Hair feels soft and very clean. Seems to be less hair finding its way into the shower drain.

Oasis
Which bar did you purchase?: Lotus
How would you describe your hair?: Wavy (Fine//Some Waves)
What are your largest concerns when it comes to your hair? : Frizz, Oil/Grease
I switched to these shampoo bars and have not gone back to liquid shampoo. I love how these lather and how well they work for my hair.
Driftwood
Which bar did you purchase?: Maui Melon
How would you describe your hair?: Curly (Loose Curls)
What are your largest concerns when it comes to your hair? : Lack Of Volume, Oil/Grease, Greying
I was skeptical about bar shampoo and conditioner at first, but once I tried ZWS, I was convinced. I have tried almost all of the scents and they all rock! My favorite is the Maui Melon because of my curly hair and the smell is amazing. My 9 year old son loves them too because you don't have to worry about using too much or too little. I recommend these to anyone that's looking for something new or better than their go-to.

What are your largest concerns when it comes to your hair? : Itchy Scalp/Dandruff, Oil/Grease, Thinning Hair, Greying, Lack Of Volume
Peppermint shampoo arrived today. The package was damaged and soaking wet wrapped in plastic from postal service with a note. It was awful all the shampoo was wet and packaging was falling apart.

Cobalt
Which bar did you purchase?: Cobalt
How would you describe your hair?: Straight (Thin/Fine)
What are your largest concerns when it comes to your hair? : Lack Of Volume, Dryness
The ZWS ships items without the use of plastic packaging, opting instead for a simple cardboard box and paper-based packaging tape which is a relief and true to the spirit of the "zero waste" mission.
I ordered the Cobalt Shampoo bar because I enjoy the stereotypical "man scent" of hygiene products (think Oldspice) and thought this sounded the closest. It met my expectations and I'm delighted! It is normally a pretty artificial-seeming scent, so I was surprised they achieved it with essential oils.
The only other shampoo bar I've used is the Sun Basin Shampoo Bars from the Good Store. The ZWS shampoo bar definiterly "softens"/melts more easily than the Sun Basin bars. I would not store the ZWS shampoo bar in the shower as the humidity causes it to melt into goop over time. If you take it out of the shower, don't run it under water, and store it on a tray that allows it to air-dry between uses, I think you can get a good 4-6 months out of it (I have a "men's" short haircut).
As far as shampoo goes, it works well! A little goes a LONG way, truly only 1 to 2 swipes and a lather will work up quick. It can feel a little stripping, almost that "squeaky-clean" feeling so be careful from overusing it and you'll want a moisturizing conditioner to go with it.
I'm pretty happy with the product. While I had some issues, the main reason I get this is to avoid plastic waste, and it is good enough for me to continue purchasing. I'm interested to try other scents with future orders!

What are your largest concerns when it comes to your hair? : Dryness
My whole bathroom smells like a spa with this conditioner bar! I love that it lasts such a long time. The key for using it with long hair is to run it along the length of your hair and then scrunch up your hair to coat all of it.

How would you describe your hair?: Straight (Thin/Fine)
What are your largest concerns when it comes to your hair? : Dryness, Damage
I've never used a bar shampoo or conditioner before, but I'm committed to make more sustainable changes in my life. Including my personal care, health & wellness routines, and the shops/brands/companies I choose to support (with my money!). I had faith in the shampoo (and it lathered up like any other shampoo 😄), but I had some doubts about the conditioner 🤔 Once I kind of figured out how to apply it, I was really impressed by how soft my hair felt after 😄 I'm totally satisfied with my purchases and I absolutely recommend everyone switch to a bar shampoo and conditioner!! 🙌🏻

Which bar did you purchase?: Maui Melon
How would you describe your hair?: Wavy (Coarse/More Defined Waves)
OK I was definitely skeptical of the idea of a conditioner bar because I have long wavy hair. But this wowed me!!!! The Maui Melon set was better than any other product I have ever used - genuinely! It is so easy to use. The shampoo gets really foamy really quick and the conditioner bar is easy to hold while running it down the length of my hair. I have actually been using it for a few weeks and it doesn't even look like it's been used at all so I can tell these bars are going to last a while! I used to use like 6 pumps of conditioner from my other brand so this is a game changer!

The shampoo is easier to carry and more dependable. It effectively cleansed my hair from pool water, leaving it soft and my curls looking fantastic.

I've tried almost all of the scents and I love each one! It lasts forever, even on my long hair. I definitely need some kind of conditioner after using the shampoo bars, and this is perfect. I only use it on my mids and ends and it feels silky smooth.
