Hair loss treatments take a long time. That’s just a fact. Almost all hair loss treatments, whether chemical, topical, or Low Laser Light Therapy can take anywhere from 3-6 months to produce results.

That’s not necessarily a bad thing; but if you’re experiencing balding, you may want a more immediate solution to cover up your rapidly thinning hair while your more long-term treatments begin to have an effect.

The solution to this is a relatively new class of products known as hair fibers. Usually made from synthetic keratins or other proteins; these products are shaken onto your head; and bind with your natural hair fibers to create the illusion of thick, full, healthy hair.

They generally last until your next shampoo, and are relatively inexpensive. The visual effect is immediate; as long as you still have some hair, you’re going to have a thicker and fuller look as soon as the proteins bind to your existing hair.

We’ve catalogued the 7 best hair fiber products on the market, suitable both for men and women, so that you can have a buying guide to refer to when you’re looking for one of these products.
