Wouldn’t be without it.

This shampoo and conditioner is just brilliant. I have highlighted hair and since going through the menopause, my hair had become very dry and dull. This shampoo just makes my hair feel so soft and hydrated and I wouldn’t want to be without it. It’s pricey but it’s definitely worth it….and it smells gorgeous.

Perfect Shampoo & Conditioner

The cool girl shampoo and conditioner does exactly what it says it does. My fine hair looks much thicker and soft to touch plus no scalp irritation which is a huge win for me as I have an extremely sensitive scalp. The products smell amazing. Give it a try you won't be disappointed.

Lasting volume

The conditioner used with the shampoo definitely give my fine hair some oomph! My only concern is that I find it hard to comb through my hair when it is wet. Hence 4 stars.

It would have been 5 star but the shampoo pop up lid does not work so every time you have to unscrew the top to get the shampoo out not very good for your product

Lovely product but no change in body.

Like with the shampoo review its a lovely product, but does not seem to give hair extra volume, none of the range does but keep on using as like smell and it does remove dryness.

Happy Customer

Was given a sample and have now ordered full size plus shampoo- this gives my hair volume in a good ‘soft’ way. I’ve a growing collection of Sam McK products, I know I can trust the styling products too. I’m 70 and don’t want to be stereotyped - I really appreciate that your company features a mature fab model who is inspiring - I find your website a lift, (as well as your products!).

I was sent samples and am now hooked

I was sent samples of these products with my last order, used them and didn’t expect much but I should have known better! Ever since, I’ve been thinking that my fine, slightly thinning hair has looked good - and wondering why… I’ve now put two and two together! These full sizes are now definitely going on my next SMcK order, to join my extensive collection of his must haves. Very pleased.
