I have some thinning in my part, and have been using Joan River's Great Hair Day for years. It gives a slight itch sometimes but is easy to brush on and gives full coverage. I bought the Toppik after reading reviews of no itch and how it works better than Great Hair Day. I kept shaking it on my head and it didn't look like the powder even came out. Then I slowly see a pile of powder forming on my hair, and I had to mix it in with my fingers. I even tried using the Great Hair Day brush, to no avail - the brush didn't pick up on the Toppik powder. I used the Toppik applicator for parts which I bought seperately, but that didn't work well either. I'm back to using Great Hair Day and the Toppik is sitting ignored in my closet.
