Matt, I have been using these for a couple of years now, personally I find toppik has been the best for me, definatley the most undetectable I think and it doesn't come out so easy, I also have recently used super millions hair, I shaved my head for a ht and my hair was to short for toppik super millions worked wanders even on really short hair but it did come out a lot with just water and can conjeal into clumps and if you run your hand through your hair loads of fibres are on your hand! Iv also tried boots nanogen and restrand but didn't really like them, for anyone who cared to look certainly with restrand it was obvious! Best thing to do would be to order a few small sample bottles from different places and see which works best for you, any other questions I'm happy to help
