Recently I received a sample of the Garnier Fructis Sleek and Shine Brazilian Smooth Flatiron Express. It claims to protect hair up to 450 degrees and decrease time and effort on difficult to straighten hair. The directions say to separate damp hair into two inch sections and apply a dime size amount onto each section. I have very thick, wavy hair and I am too lazy to separate it all into two inch sections so I just applied it to my whole head. The first time I used a little more than a quarter size amount and it left an enormous amount of build up on my hair. It didn’t show on my hair but when I brushed through it a couple of hours after straightening, my brush was covered in white flakes. Through trial and error I found that the perfect amount for my hair is about a nickel size amount spread throughout all of my shoulder-length hair. I put it in after I shower before bed, let my hair air dry as I sleep and straighten it when I get up in the morning. It makes my hair so much easier to straighten and it helps to control the frizz that comes on the second day after straightening (which I don’t like) but doesn’t eliminate the texture and little bit of wave that comes back (which I do). My final opinion on this is that a little goes a looong way so use sparingly but if you have thick wavy hair this is a very helpful styling tool.
Have a great day!
