SOLIDSILK™ Seaweed Conditioner

Regular price $35.94 $25.16 Sale

- new bar size and bundle discounts - 

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 to use the SOLIDSILK™ conditioner - long version - read the post here.

Quantity options:

1 bar at regular price

3 bars (discounted 30%)

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

So easy to use. I only have to wash my hair twice weekly. What i like most about this product, is it doesn't strip my color. The ingredients are simple and NO TOX!

Wonderful products

I purchased the shampoo,conditioner and deodorant, I couldn't be happier, not only the fragrance is amazing, but knowing I am doing a good thing towards our environment makes the purchase even better.

Best shampo and condition are bars that I have found!!

I have tried so many of these and I love this shampoo bar and conditioner bar they leave my hair feeling clean and soft…

Best solid conditioner yet!

I’ve tried a few brands of solid conditioner and by far this is the best. It’s very “slippery” and detangles my curly hair nicely! Love the scent too

I have been using this shampoo bar (and condition bar) for years!

This is the only shampoo bar and conditioner bar that have worked for me! I can brush my hair afterwards, and it does not leave a waxy coat on your hair.

Before finding these bars, I went through a few brands of shampoo and conditioner bars that claimed they didn't leave a film on your hair, and all failed.

The shampoo bar lathers up nicely. It truly and effectively cleans, and the conditioner bar truly and effectively conditions. The shape of the bars is great, the curved side works excellently for your head and the flat side excellently for the length of your hair. And the new size is just right for the length of time it will remain on the shelf.

My hair feels and looks great, silky smooth like butter! And I have a lot of hair - thick, wavy hair. I HIGHLY recommend these bars. You won't be disappointed!

I would only recommend that there is some way to tell the difference between the shampoo versus conditioner bar after some prolonged use, maybe a natural tint for one or both. I keep them in a certain place/order but if I or someone accidentally moves them :) I have to figure out which one is which. I HIGHLY recommend these bars. You won't be disappointed!

I Was Doubtful...But I Tried It...Now I Love It!

Was expecting another in a series of low-lathering letdowns, but SOLIDSILK Seaweed Shampoo is GREAT. Lathers up quickly, rinses off well and leaves my hair squeaky clean. For real...this is the good stuff! If you want squeaky clean hair without all the crap of bottled shampoos (they can sell it for 97cents for a reason) , try SOLIDSILK Seaweed Shampoo!

love the way it lathers

First venture to conditioner bars

I switched to bars to cut down on packaging waste. I'm really pleased with this product so far! My hair has a better texture than what I noticed with my (expensive) salon brand products. I have REALLY thick long hair, so it is a bit challenging to get the product on all my strands. However, I'm going to start using a claw clip in the shower to section off pieces at a time to run the conditioning bar down. I think this will actually cut down on the time it has been taking. I'm really glad to have found this product. I feel good about the ingredients, company, no waste, and how well it works!

First venture to shampoo bars

I switched to shampoo bars to use less wasteful packaging. I have SUPER thick long hair and was nervous about trying bars instead of the liquid salon brand I was using. I am SO PLEASED with this product! These shampoo bars slightly outperform my old salon shampoo in terms of being softer and fluffier. These are also way less expensive which I really appreciate. I think their estimate of how long the bars last seems accurate. I wash every other day and think I will get about 3 months from a bar. However, even if it lasted 2 months it's still way less expensive than the salon brand I was using, which I really appreciate! I've learned if I apply the bar directly to my hair that I will have some build up that I can tell feels a bit waxy, but once I started making a lather in my hands and then applying that to my hair I have loved the results. It is also an adjustment as obviously as there is not water, so it does take my a tiny bit more time in the shower. However, I
definitely will continue to use this product!
