To make you feel like a mermaid
big shampoo

A volumising shampoo made with seaweed and sea salt. While the salt lifts the hair and adds body, it also softens the hair alongside extra virgin coconut oil and protein-rich toothed wrack seaweed. Lemon and lime allow the hair to shine as they allow the cuticles on your hair to lie flat, meaning they reflect more light. Use a small amount on wet hair and work it in well to build lather.

I have very fine, flat hair so have spent years blowdrying and saturating my hair with different volumising products with very poor results. Believe me, I am not being dramatic when I say that this has been life changing. With this shampoo my hair feels and looks thicker without even being blowdried or with other products. Highly recommend.

TL;DR - This gives you shine and lots of volume. Not suitable for my thick hair but loved by my friends with thin - normal hair types.

I received a sample of this from the store and eagerly tried to use it. It smells fantastic and looked like some sorbet dessert.

When I first tried this product I just scooped some off the top and it was mostly salt, hardly any lather. Once I stirred it with my finger to grab a little more, I got a TON of lather and it was very moisturizing. This is a great shampoo and gave me a ton of volume and shine. You only need a small amount.

I have psoriasis on my scalp and am constantly trying to find new things for keeping it at bay!
I went in store looking for a scalp scrub and was recommended this by a shop assistant.
It’s a god send now- I scrub my scalp with Big and then moisturise with Super Balm and wash with Soak n Float!
Big was the final piece of my scalp routine!
