Hair-Tek hair fibers offer a similar hair fiber concealer for hair loss as other products on the market, but Hair-Tek has two things, which distinguish it from most other hair fibers on the market. One is that they do not include keratin in their product, which they say other companies do as a marketing gimmick. The other is that the product is made in the USA rather than imported from China. Based on a comparison of price by volume, Hair-Tek has one of the better prices for the amount of hair fibers you get.
