Just the right amount of volume!

If you want big, dramatic volume, this probably isn’t the product for you. But for me, K18 AstroLift gives just the right amount of volume and a little grit without making my hair feel heavy. It still feels soft and touchable, holds up in humidity, and looks amazing the next day! I LOVE this product and will buy it again and again.

Not volume at all

This was one of the most useless products I’ve ever bought. It doesn’t add any volume to my hair, not even for an hour. In my opinion, Color Wow makes the best volumizing foam.
