Regular price $18.98 $13.28 Sale

Ditch the plastic bottle and try switching to a concentrated solid shampoo. Infused with seaweed extract and macadamia oil, this shampoo is gentle and moisturizing for your locks. It rinses clean without needing vinegar, even in hard water. Super long-lasting and SLS-free too!

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. Our salon-quality 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 solid 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 our solid 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.

How to use the solid shampoo - long version - read the post here.


1 oz (28g) - can last 20-40 washes
3 oz (85g) - can last 60-120 washes

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.

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.

Typically for a long haired person with lightly wavy to straight hair who shampoos every 2-3 days, the 1 oz size will last around 1-2 months. The 3 oz size will typically last 3-6 months. These are rough estimates based on customer feedback and will vary per person.

Solid seaweed shampoo and conditioner

My hair is beautiful, shiny and squeaky clean. I’m obsessed with hair products and own many shampoos and conditioners. This is one of the best!

Love this

It smells nice and leaves my hair feeling clean- love that it’s low waste too

Excellent product

I really love this bar. I have long, straightish caucasian hair. I wash my hair about every other to every two days and use this bar plus the No Tox Life conditioner. It doesn’t lather up a ton, but once you get it worked through your whole scalp it works great. I keep mine in an old cut off stocking so I can get some lather going without breaking up the bar. It rinses very clean and squeaky (my fave). If your hair is long I’d recommend the conditioner too. Since the shampoo isn’t very sudsy, the conditioner plays an important detangling role. I’m on my second bar and I look forward to using it every time!


Solid Seaweed Shampoo

Salon quality

I made the transition from a pump shampoo bottle to a solid bar soap. The shampoo bar has a yellow tone compared to the conditioner bar.

The solid shampoo lightly washes your hair but it doesn’t strip your natural oils. I can feel the moisture lock in when I rinse. It has helped me detangle my waist length hair in the shower. This product has replaced my detangler spray bottle and my leave in conditioner. I have not been in need to cut my ends. My spit ends have minimize and I have added length to my hair. When I brush my hair the comb glides off. My hair doesn’t fall in the shower anymore. Even when I comb with a bamboo brush, it’s not a battle to brush. This bar gives me a natural shine, and when I do my hair the waves hold for two days looking natural.
These are perfect for traveling, and makes it easy to carry, grab & go without changing my hair routine.

Beware the bar is made of natural oils that it will make your shower stall slippery. When using the bar you will need a soap lift, or else it will wash away. It can be easy to confuse the bars. I wish they were label (or had a flower pedal) with an S: for shampoo to differentiate between the shampoo and the conditioner.

Overall, its been four months and have enjoyed the plastic free shampoo bar.

Absolutely love this

It lathers well and is not too drying. Hooked for life!

Only shampoo I use!

I’ve bought the seaweed shampoo and conditioner bars multiple times and it’s the only product I use in my hair. They last long with proper care - I’ve had my current bars for over a month now and they’ve barley gone down in size.

I love it

I was honestly pretty afraid to make the switch to dry shampoo. I have been using the function shampoo & conditioner for a few years and really liked it, but wanted to cut back on my plastic consumption. I tried the bar shampoo and conditioner from No Tox Life while my boyfriend was away for two weeks (just in case my hair was a terrible greasy mess). I loved it!! I'm working to finish up my existing bottles of liquid shampoo/conditioner but can't wait to officially make the switch! Like other reviewers have said, it would be nice if the two bars were either a different shape or color (naturally dyed?) to more easily distinguish between the two

Love it!

Great product! Shampoo suds up like I want, smells amazing, and leave my hair feeling clean.

Great Shampoo Bar, Can’t Wait to Try the Conditioner!

Really loving the shampoo bar so far! My hair is softer and has more volume than when I’ve used other bar shampoos. I have curly/wavy hair and the shampoo really accentuates my curls. It soaps up well and smells lovely.
