Ditch the plastic bottle with the salon-quality SOLIDSILK™ vegan seaweed shampoo bar.

Infused with seaweed extract and macadamia oil, this shampoo is gentle and moisturizing for your locks. It rinses clean, even in hard water. 

Our SLS-free formula is made with cleansers designed for sensitive scalps. 

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):

  1. Wet hair thoroughly.
  2. (most hair) Rub the solid shampoo on hair lightly, first at the top of the head and then towards the base of the neck. Place it back on your soap holder. Use fingers to massage the shampoo in and create the lather. A little goes a long way. Excessive rubbing of the product on the head will cause your product to be used up much faster than normal.
  3. (brittle hair types) Rub hands on the solid shampoo until you have bit on your hands. Place it down on your soap holder, then use fingers to work shampoo into hair and create lather.
  4. Rinse well with water. (no vinegar required)
  5. Use the SOLIDSILK™ conditioner on lengths and ends.
  6. Rinse well with water. 
  7. 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.

Quantity options:

1 regular (1.5 oz) bar at regular price

3 regular (1.5 oz) 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 shampoo that is mostly water. Most shampoo formulas in a plastic bottle are upwards of 75% water. 

The length of time each bar lasts depends on proper storage, how often you shampoo, how heavily you use it, hair length, curls and thickness, etc. Most people find the shampoo lasts about half the time of the conditioner.

Typically for a long haired person with lightly wavy to straight hair who shampoos 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

Super Happy

I have been using this Shampoo for about a year and just love it

Seaweed Shampoo is the best shampoo ever.

My hair stays "cleaner" longer, is shinier, looks and feels healthier. I've given a bar of the shampoo to my sister and daughter and they both agree and love it too. My 80-year-old sister says she will never use any other shampoo again.


Makes my hair feel so soft!

No more plastic!

Haven't used it, yet, but my daughter likes it and she's picky. Will be buying, again.

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!
