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.

"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

"This is the only shampoo that I have used for over 5 years. I have scalp psoriasis and this really helps with it." - pennymorris36

How to use:

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

I’ve been using BIG since 3 years now, and I think it can show how much I love it. I was using Rehab before as my hair grease fast, but left me with no more volume. I then swap with BIG and from washing my hair every 2 days I now wash them twice a week only. Can’t recommend this...

It may look a little clumpy,
But if your hair is looking frumpy,
You might want to buy yourself a pot.
You’ll be surprised, I kid you not.
It smells like detergent a little bit
And the salt gives it a little grit
So it’s a little strange to rub on your hair
But keep going if you dare!
Because when you rinse out all the stuff
Your hair will be like HOLY FLUFF!

I tried this shampoo on a whim whilst buying a bunch of other lush shampoos as well because I was curious to see which one I'd settle for. I initially tried the 130kg and am now coming back to say that out of all the Lush shampoos I'd bought that day this one takes the crown for me.
