The same amazing conditioning and silky soft hair power, this slightly updated formula has no noticeable difference from the original per our testing and feedback 💚.
Ditch the plastic bottle with the salon-quality SOLIDSILK™ vegan seaweed conditioner bar.

Infused with seaweed extract, rice protein, cocoa butter, vitamin B5 and macadamia oil, this conditioner bar is gentle and moisturizing for your locks. It's lightweight enough to be used every time you wash. 

Suitable for many hair types, from straight and fine, to thick, wavy, frizzy, as well as color treated hair. pH balanced to protect & prevent environmental damage. Our premium ingredients help your hair feel soft and manageable. 

How to Use (Short version):

First, shampoo using the SOLIDSILK™ shampoo and rinse clean.

(most hair) Rub the conditioner bar along hair lengths and ends, place bar back on your soap holder, then use fingers to massage until hair is soft and slippery feeling. A little goes a long way. Excessive rubbing of the bar on your hair will make it go faster. 

(brittle hair types) Rub bar hands with a little water to create a creamy conditioner concentrate, then rub hands through lengths and ends.

Leave in up to 2 minutes for a deeper condition, or rinse immediately.

Rinse well with water. (no vinegar required)

Keep out of eyes! It is gentle but not designed to be used in the eyes, if you get a little in there then rinse gently with clean water.

How long they can last:

These bars are highly concentrated. You are using your shower water to dilute the product instead of buying a bottle of conditioner that is mostly water. Most conditioner formulas in a plastic bottle are upwards of 75% water. 

The length of time each bar lasts depends on proper storage, how often you condition, how heavily you use it, hair length, curls and thickness, etc. Most people find they last about twice as long as the shampoo.

Typically for a long haired person with lightly wavy to straight hair who conditions every 2-3 days, the 1.5 oz (42.5g) bar will last around 2-4 months. The 3 pack, 4.5 oz total (127.5g) would last around 6-12 months. These are rough estimates based on customer feedback and will vary per person. 

1.5 oz (42.5g) bar - can last 30-60 washes
1.5 oz (
42.5g) x 3 bars = 4.5 oz (127.5g) - can last 90-180 washes

I got both the shampoo and the conditioner bars. They leave my hair nice and soft! Much more light weight than my old shampoo and conditioner.

Judy M. (North Hollywood, US)
Excellent shampoo

Even if it weren’t sustainable and zero plastic, this would be my favorite shampoo. It isn’t drying, it sudses just enough, and if you find a container to keep it from being wet all the time in the shower (I use a small leftover container), it lasts a long time. It also smells great, but not in any overpowering way. Plastic free in ‘23!

Anni S. (Los Angeles, US)

In my experience I go through the shampoo faster than the conditioner bar and would prefer for the sizes to be swapped. I've never found a better bar shampoo and conditioner than these, and absolutely prefer these products over any liquid versions out there! Please make the shampoo bars bigger again!

I’m a Convert

I really love this bar shampoo. Not as in “it’s the best bar shampoo” but as in the best shampoo for my fine /thin hair. It leaves my hair with a fabulous beachy wave look and clean feel. I love it!

Great quality, just such small quantity

I love this shampoo bar. I got lucky that this was the first shampoo bar I tried (it was a gift!) and it did wonders in cleaning my scalp. Even my hairdresser noticed a difference! I have very thick, high-density wavy hair, recently cut to shoulder length. My only complaint about this amazing shampoo bar is the price given that I can only make it last about 8-10 weeks, in order to use enough of it to really clean my hair and get the desired effect. However, I will happily continue to use the rest of my 3-bar bundle!

Thank you! Glad you are loving it. We are working on new additional formulas with lower price points if the price is an issue.

Affordable fantastic shampoo. I used to use expensive salon shampoo/conditioner. My hair is happy and healthy and no plastic to waste. What could be better

Zoe (San Diego, US)
Great Low-waste Option for Wavy/Curly Hair

This shampoo/conditioner combo has become my favorite, as it provides just the right amount of suds and cleaning power for my thin/fine wavy/curly hair. I find that the shampoo wares down faster than the conditioner, but I just buy the 3-pack of each so I can have extras on hand. I also keep it on a rack that allows it to try well between uses, as this can help extend its life. Travels well too!

margaret p. (Berkeley, US)

I’ve been using this for a couple years now and my hair is healthy and I’m happy.
