My wife having problem of thin hair. She consulted doctor many time. Then she started applying egg on her hair but not getting any difference. Then she went to beautician and tried to fix this problem, no success, then she saw one place Toppik Hair Building Fibers ad, and then we purchase this product and you cant believe it started working. When I first started, I'd get it in my face, leave some in the shower or on the pillow, but that changed quickly with experience. Like with any new product, you get better at using it. The powder does go everywhere when you're sprinkling it in, but it's easy to clean. If you get it on your clothes, you can brush it off with no streaking or staining. I sleep with it in my hair and the residual powder is never on my pillow If your hair is thinning and you're having trouble styling it in a way that doesn't call attention to your bald spots, you owe it to yourself to try this product. Use it as directed and you'll be very pleased with the results.
