Summary:

Finally Hair maintains being the highest quality and lowest cost hair building fibers on the market.  Our products are priced between 25% to 75% lower than unrelated brands like Toppik, Caboki, Xfusion, Bosley, Viviscal, Hairmax, Kerafiber, Strand, Infinity, Hair Illusion, Mirage, Nexgen, Focus, Megathik, Surethik, hairsoreal, and Nanogen on its refillable bottle of fibers.

Finally Hair also sells refill bags of hair building fibers that can be used in most brands of bottles for from 50 to 80% less per gram.  I couldn’t find refill bags from companies like Toppik, Caboki, Xfusion, Bosley, Viviscal, Hairmax, Kerafiber, Strand, Infinity, Hair Illusion, Mirage, Nexgen, Focus, Megathik, Surethik, hairsoreal, and Nanogen which means you have to buy and pay for their bottle over and over again.

Most bottles of fibers open.  Here is a picture of the components of a Finally Hair bottle which is similar to other manufacturer’s bottles:

You can order refill bags once your container is empty:

We hope this price comparison helps you to decide on which is the best hair fibers brand and which suites your pocketbook or wallet most effectively. We take pride in providing the best quality fibers at the best price anywhere.
