I went through a major hair shed a couple of years ago, which was when I got my first Toppik Fibers. This product has helped preserve my vanity by hiding my widening part and other thin spots on my head. Toppik blends in so nicely and stays put until your next wash. I don't use the spray nozzle attachment, I just sprinkle it on and pat it out to blend in, as they demonstrate in the video on Toppik's website.
