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. 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

Truly silky--but keep it dry between uses

I have tried several solid shampoos, but this one may be the best. I immediately loved how it made my thin, fine hair feel: soft and silky, and not weighted down, even in our hard well water. But I kept it in our small shower, and it became very gooey, making it messy to use. I'm going to try again, because I like the product so much, but this time I'll keep it outside the shower to dry, and move it back and forth between uses. My short hair doesn't need conditioner--and I love that this formula does not need a vinegar rinse as a follow-up. Thank you once again, No Tox Life!

Okay so not going to lie I was a little skeptical about using an all natural shampoo and conditioner, but I must say I love love love this product! The very first shower I took and used this product I felt instantly refreshed and the cleanest I've ever felt. I also bought the body was 3 pack variety scent which I also loved. I highly recommend this product to anyone and everyone!

Not your fault.

I love your products. Unfortunately, I have very hard and they did not work well.
As I said, Not You Fault❤️

Surprisingly silky!

My hair has been getting coarser as it turns grey, so I didn’t expect much from a bar of shampoo. Frankly, I just wanted to check having tried a more eco-friendly option off of my to-do list. I’ve been pleasantly surprised to find that this shampoo and conditioner has restored the texture of my hair to its original soft luster. My husband likes it too, although he doesn’t bother with the conditioner.
Just bought a few more bars for my bathroom “pantry.”

Decent enough- I overall like it

So overall I do like this shampoo. At first, I found it wasn't working. I normally wash my hair every other day, by the second day it looked as if I never washed my hair at all, I was so greasy. I contacted NoTox- they suggested I use more than I was using. (They answered very quickly and offered to do research on my old shampoo to compare and potentially find the problem, but I knew I just probably needed to use more) That definitely helped. My hair is very thick (as well as long) and the soap wasn't penetrating the under-layers of my hair. I do find that I still look a little greasy sometimes on the second day depending on how much I used, but it's definitely bearable and not too noticeable.

However, as a consequence of needing more, I go through it more quickly. I ordered in early August, but I contacted NoTox on August 19- I should meet the 1 month minimum for the sample bar (this review was placed on Sep. 3). It is a little expensive for 1 month's use for me. I'm going to try other brands to see how they compare.

As for the positives, I did have a very itchy, irritated scalp for months using my old shampoo. I had woken up scratching the back of my head more than once. After switching, that went away completely. My hair on wash days is very soft as well. Other than my personal cost-to-use ratio, I quite enjoy this shampoo. If I find other brands don't work as well or I don't like them as much, I'll probably be a repeat customer.

Love it

Wasn’t sure how it would clean but it does a great job and leaves my moderately curly, slightly coarse hair clean, bouncy and pretty tangle free. Lathers like a champ, so don’t use too much. Overall I am happy and would purchase again. Don’t know how long it lasts as I don’t wash my hair every day or even every other day some times. Gets like that when you get older and realize all the washing is pretty damaging to hair life and growth.
