Solid Seaweed Shampoo

Regular price $14.98 Sale

- both sizes listed at sale prices - 

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.

Seaweed shampoo

I love the seaweed shampoo-it has a light scent, suds up nicely with slight rubbing around my head and rinses clean. It tends to be soft so I keep it on a soap holder which drains.

such a good solid shampoo

Love this solid shampoo- and highly recommend the conditioner as well. I have tried other solid shampoo and conditioner before and these are by far the best. Easy to use- easy to wash out and leaves hair feeling moisturized and clean. Get the big bars! When one bar is getting too small, I press it into the next one and keep on using it.

The very best

I’ve tried many shampoo bars and this is BY FAR the very best. Lathers up and cleans beautifully, leaving my hair soft, smooth and full bodied with no need to rinse with ACV. Another very fine product from No Tox Life!

What I’ve Been Looking For!!

My hair is so particular and for years I treated it terribly using the standard products advertised and using heat etc. After realizing how damaged my hair had become I wanted to reroute and only use products I knew wouldn’t hurt my hair. I started off using Castile soap which didn’t hurt my hair but no matter how I adjusted my usage and dilution and rinses etc. my hair was always greasy. Then I found this, it leaves my hair silky and smooth and it feels light. I love it so much!!
