While you could just style your fine hair as usual as you wait for the products to work, Amazon shoppers found a better solution. Toppik Hair-Building Fibers will "instantly and naturally" fill in thinning spots and hair lines, and you can get a bottle for $24. Available in Amazon's Premium Beauty section, Toppik powder will create the appearance of a thick and voluminous head of hair. It's made from natural keratin, which is the same protein that's found in your hair, making it easier to blend in. The fibers come in nine colors, including shades of black, brown, blonde, auburn, and gray. Courtesy Shop now: $24; amazon.com You can apply the powder to your hair with either the included sifter or spray cap. All you have to do is dry and style your hair like you usually do, pour or spray the fibers into your thinning areas, and gently pat it in to disperse the pieces.
