If you have color treated hair or use styling products that damage your hair like straighteners, blow dryers, curling irons, etc. then you probably need Tresemme Split Remedy Leave-in treatment. It reduces frizz and split ends up to 80% within the first three uses! I straighten my hair almost daily and it is very damaged, so I was trying to find a product to repair my hair and I found this. I started using it about two weeks ago and now I cannot even find a split end. My hair is so much softer and healthier. I apply it while it is damp, focusing mainly on the ends, and reapply it, if necessary, to the ends when I finish styling my hair. It is an amazing product and by far the best leave-in treatment I have used. I hope you all have the amazing results I have had!!
