They do what they say work so well for my hair

Love these for my hair! Works amazing and not a heavy formula. Worth the money!

Adds a bit of volume, but no more than other cheaper brands do. The serum definitely makes each strand seem fuller but leaves a chalky feel to your hair. My hair overall is definitely dryer since using these so now only use them for occasions. I won't buy again

Definitely makes my short pixie hair a lot fuller after using both of these. 

I cannot rate these products high enough.  My hair was quite badly snapped because of bleach and I started using the WOW products & in 1 month it’s more or less back to full strength.  Going forward I’ll be using this range and nothing else.
