I have fine thinning hair.  I used two other products before trying Toppik Hair Building Fibers. I used a color spray aerosol and a brush on powder.  I didn't care for the aerosol spray because you had to be so careful not to get overspray on your clothes.  The brush on powder does work for small areas, but my hair continued to thin and it was time consuming to cover the top of my scalp.  This powder was suggested by a sales clerk at a beauty supply store.  It seemed to work better and was easier to use.  If I had a choice, I would like not to use any product, but I don't want my scalp showing so I am very happy to have a product like this.
