Positive Aspects

Toppik: How the product claims to work: For those with little or moderate thinning, Toppik makes hair look cosmetically fuller, while still looking natural.  Toppik is made of keratin fibers, the same protein that comprises human hair.  To apply, sprinkle fibers directly from the container onto the thinning hair areas of your scalp.  Using natural static electricity, these fibers attach to your existing hair.  With the use of Toppik Fiberhold Spray, Toppik has increased durability.  Toppik does wash out, so it will also come out if hair treated with Toppik is submersed under water.

• Toppik is 99% organic keratin and 1% approved colorant.  It's considered safe to use with topical treatments, whether they are natural or pharmaceutical, and are also safe to use if you are taking any natural or pharmaceutical treatments internally. 

Positive Aspects
It is excellent at cosmetically increasing the volume and thickness of thin hair. It comes in auburn, black, dark, medium and light brown, blonde, grey, and white.  Toppik is for men and women

Negative Aspects
Because Toppik has no hair loss treatment properties, there will probably come a time where Toppik is ineffective because a certain amount of hair is required for it to work.
