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.
