I have very fine hair that damages easily. Since I have been trying to grow it out, I have had the WORST time with split ends. I purchased Neutrogena deep recovery hair mask, and this did nothing- even after leaving it on for 20 minutes. I even bought moroccan argan oil and saturated my hair with it every day, but that didn't work either! I was becoming very frustrated and did lots of reading reviews on conditioners. I saw good reviews for this so I gave it a whirl. I leave it in my hair for about 5 minutes while washing everything else, then rinse with cool water. It's amazing how soft and smooth my hair is now after a shower. It doesn't weight my hair down, either. Truly a special buy!
