Lush's best selling, sea salt shampoo. Reach for this pot when you need a serious boost in shine and volume. Packed with hand-harvested sea salt and lemon infusion, it will give softness and texture with the incredible scent of neroli and vanilla. 

"Omg! This product is a miracle worker! I have thin wavy hair and this product just blew me away! It volumed my hair so much and at the same time it made my hair so soft and smooth. I wouldn’t recommend using this daily but they don’t lie when they said Mermaid hair! 100% recommended" - marygattellaro24_2060225

"Honestly the most gorgeous shampoo i’ve ever used, the scent lasts for days in my hair i also love to use the roots hair mask treatment as it feels amazing and my hair is sleek and silky after will continue to buy more!" - hannaholiviab_7

"This is so amazing for my hair. I have a very thick scalp with a pixie cut, so this gives me such good volume, and also makes my hair so healthy! I'd recommend this for anyone with a thicker scalp, it doesn't weigh me down, and leaves it feeling so healthy." - kelleher.carolyn

How to use:
Use a small amount on wet hair and work it in well to build lather.

The best shampoo hands down! A pot will last me 6-8 months as you only need a very small amount (it foams up like crazy) and I just use it on my roots/scalp to get big volume. It smells amazing and does wonder for my fine hair! My boyfriend uses it as well and it has made his scalp psoriasis...

BIG has become my favourite shampoo: it smells divine, feels even better and makes my hair so healthy and shiny. A little goes a very long way! Everyone should try it! P.S.: I keep a little spoon in the shower to scoop it out of the pot. That way, none gets wasted.

This is hands down the best shampoo I’ve ever used! I was apprehensive at first, but I’m so glad I brought some. I have very sensitive skin and before this product, I used to wear gloves or use the products recommend by medical professionals (which always smell nasty) to wash my hair. BIG doesn’t irritate my skin and leaves my hair feeling so clean and fresh! A little goes a long way,
so it’s definitely worth the price. Plus it smells divine!

I love the smell of this shampoo, and adding sea salt seems like such a good idea; it is really volumising. But something - probably the salt - in this shampoo dries out my hair a LOT, and I have naturally straight, oily hair. I wash it every four days, and have to condition it each time, otherwise my hair ends up tangled and as brittle as straw. But since the dryness is manageable, I’ll switch back to a LUSH shampoo bar when it’s finished.
