Review title is Not impressed [SEP] Lately, I have become enamored with hair building fibers for both root and scalp coverage. The results have been amazing, and many of the products I have used contain Keratin or Gossypium as the primary ingredient. The Toppik Hair Building Fibers contains 99% Keratin, but the fibers were larger and coarser than others and did not blend or adhere as well. It wasn't the natural-looking coverage I had come to expect. Just goes to show they're not all the same.<br /><br />** If you found this review to be helpful at all, please take a moment and click the button below to let Amazon know. Thank you so much 😊 **
