I used the Toppik Hair Fibers for a week before using the Fiberhold Spray. While I liked the hair fibers a lot and was happy with the product- The Fiberhold Spray definitely holds my hair in place and helped attach the fibers to my natural hair. Without using the spray the hair fibers looked a little "fuzzy" or light dust was a little on my head. With the fiberhold spray the fibers darken a little and thicken my hair. My hair does not feel stiff and does not attract dirt. I use the Fiberhold spray every day now... and it doesn't add any build up of product either. I recommend it!
