Mad Volume: Lush Big Shampoo Review


This is my lazy-summer-day shampoo, and I’ve been loving Big for years now as an occasional treat. Because I’ve started using it again lately, I figured a quick review would be appropriate! It’s one of Lush’s best-sellers and it’s loved by many, but it’s not for everyone and it won’t fit every hair type. I hope my experience with this shampoo will give you a good hint of whether or not it’s going to work for you!

What It Does

It’s called Big for a reason! Its main purpose is to volumize hair, using loads of sea salt. It also cleans your hair thoroughly and smells amazing.

Here’s how I use it! I grab a walnut-like amount and spread it in my hair, lather (it lathers very nicely as it does contain SLS, but the lather is smooth), and rinse. I then use a crap-ton of (non-Lush) conditioner on my roots, because it does get your hair dry and frizzy if you skip this step. I then towel-dry my hair (it’s bad for your hair, yes, but it’s what gives me a wavy texture with volume) and let it air-dry.

Does the SLS bother me? Not really. I generally don’t like using harsh detergents on my skin and hair, but in this case, I feel like occasional use of Big doesn’t hurt. I do use clarifying shampoos every once in a while, and they contain SLS to deep-clean.

TL;DR It’s perfect to gives your hair body and/or hold waves without the need to add more products or heat.

Who It’s For

You might like this shampoo if you have hair that isn’t prone to frizziness, if your hair is fine or lacks volume, or if your hair is naturally wavy and you want to rock that texture. Again, this does have Sodium Laureth Sulfate. If you don’t want to use anything harsh OR strip your hair dye, it’s not for you!


  • Legit volume.
  • Cleans well.
  • Makes your hair smell super nice.
  • Mostly natural ingredients.
  • Vegan.


  • Can be drying or cause frizz.
  • The packaging gets gross and is annoying to use.
  • Kinda pricey for what it is.


I personally love using this shampoo on my long, fine, naturally wavy hair. It eliminates the need to use anything extra out of the shower, or heating tools. My hair just doesn’t look as nice when I air-dry it if I don’t use this shampoo. Is it gimmicky? Maybe a bit. But it smells so good and works out well for me.

Have you tried Big? What’s your experience like?

    Hi! I use your blog as a reference to look for cruelty free brands and whatnot, and it’s been sooo helpful. I nominated you for the sisterhood of the world blogger’s award. Go check it out!
    Thanks! :)

    I’ve always wanted to try Lush’s shampoos! After reading this though, I might want to try a different one. My hair is very dry (bleached/colored) so that makes me worry about this one.

    One big draw back for me as well is the packaging. Same thing with the shower jellies, which i own. It’s a total hassle.

    • Suzi

      Definitely, the packaging is pretty annoying! Ask for samples before you buy though, because not all of their shampoos are great.

    I just ordered this! I read reviews that it was drying so I also ordered a rich conditioner and will be getting some hair treatments too to prevent it from becoming too dry. I’m really excited! My hair is kind of thick already but isn’t what it used to be due to dying and using heat tools a lot. But I dyed it close to my natural color a while ago and am now growing it out. It’s wavy or curly, depending on styling/if I go to bed with my hair wet or let it air dry. I’m a little prone to frizz but hopefully conditioners and smoothers will help that!

    I just discovered your blog and I am so thankful to have stumbled across this little gem! It is so helpful and I love reading about all the different products. Until recently I was ignorant to the fact that so many of my favorite products still test on animals. Not my favorites anymore. I will be using your site as a guide to find products to replace them all. Thanks so much. (:
