My stylist told me about Toppik when she noticed how thin my hair was getting to be.  She purchased the 0.36oz/10.3g for me from the local beauty supply.  Even with her discount it was almost $25.  But I really liked how Toppik camouflages my thin spots.  Only a couple of people have noticed that there is something different with my hair.  Only one person realized what the difference was, and only because she'd also used Toppik.
