I'm what you might call "super cheap" about beauty stuff. I generally use what sample sizes I get and then by the time I use it up, another brand has come in my box. This brand of product is the exception for me. Both products that I have received as samples in my box, I've HAD to buy full sizes of! This Protect & Volume is awesome on my super fine, getting thinner everyday hair. I don't generally use a lot of heat tools (maybe 2-3 times a month), but I live in a hot, dry, windy climate and I love the protection I get from this product as well as the volume! The volume! Even my day 3 hair wasn't weighed down! Yep, I am for sure getting this in the full size. The order is already placed.
