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.

Too Drying

I wanted to love this shampoo bar, because the conditioner bar is absolutely amazing. Unfortunately, it makes my scalp dry and itchy and has given me dandruff. I've been using it exclusively for two months, so it isn't a matter of getting used to the bar. Probably not the best for dry hair/scalps.

Solid Sea Weed Shampoo

I LOVE this shampoo! It lathers vey well and has a clean fresh scent. It leaves my hair soft and has a really healthy feel. I would definitely recommend it but get the larger size - I don’t think that it melts away as quickly.

Seaweed shampoo is great!

I have, shall we say, particular hair and this has been the only shampoo bar that doesn't turn my hair into gunk. I love it.


Solid Seaweed Shampoo

Love it!

I love love LOVE this shampoo bar! I have tried several different shampoo bar brands and honestly gave up because none of them worked for me. They either completely stripped my hair or left it feeling waxy and greasy. I took a chance on this bar and I’m so glad I did! It smells amazing and leaves my hair feeling so soft and clean. The conditioner is great too. I’m buying more right now so I don’t have to worry about running out! I only use a tiny bit each time I wash so I’m hoping one bar will last a while.

Love it!

I didn’t know what to expect but it’s fabulous! Nice lather and my hair feels so clean!!

Stop the plastic!

We are eliminating plastic waste with No Tox Life. What a great product! I love it.

All time favorite shampoo and conditioner bars!!

I can rave about No Tox's shampoo and conditioner bars all day. I have long, curly hair and was extremely skeptical that a shampoo bar wouldn't work for my hair type. I gave it a go around a year ago and haven't looked back (I did watch a quick tutorial before hand to make sure I was using it correctly). I've actually referred multiple friends who also are loving the bars. Of course, every hair type is different, but for me, this is the best shampoo and conditioner I've ever used. *And that's saying a lot because I've tried multiple bottled brands throughout my adult life, including the popular brands specifically for curly hair and others that are higher priced.


I love the shampoo. Never going back to other shampoo.

The best!

The smell is incredible. It doesn’t go bad quickly and it’s a great texture!
