How to Use Hair Fibers for a Natural, Full Look (Step-by-Step)
Learning how to use hair fibers correctly is the secret to a flawless, undetectable finish. Follow these professional steps to get the most out of your Finally Hair refill:
-
Start with Dry Hair: Hair building fibers rely on static electricity to bond to your natural hair. Ensure your hair is completely dry; moisture will cause the fibers to clump.
-
Style First: Arrange your hair to cover as much of the thinning area as possible. Applying fibers after styling ensures they sit on top of the strands rather than getting buried.
-
Shake or Spray: * Shaker Method: Hold your refillable bottle at a 45-degree angle and shake gently over thinning areas.
-
Applicator Method: For hairlines, use an applicator pump for pinpoint precision.
-
-
The “Pat” Technique: Gently pat the area with your hand to help the fibers settle and disperse evenly. This helps the keratin fibers “lock” onto your existing hair.
-
Lock it in: Finish with Finally Hair Fiber Lock Spray. This creates a wind and sweat-resistant barrier, ensuring your “hair fibers” stay in place until your next shampoo.
Pro Tip: If you are refilling a bottle from another brand like Toppik or Xfusion, ensure the bottle is completely dry before pouring in your 57g Finally Hair Refill to maintain the static charge.
Frequently Asked Questions About Hair Fibers
1. What are the best hair fibers for thinning hair? The “best” hair fibers are those made from high-quality keratin or keratin-style resins that mimic the structure of natural human hair. Finally Hair fibers are designed to be lightweight and electrostatically charged, ensuring they bond to your hair strands without clumping or looking artificial.
2. Can you use hair building fibers every day? Yes! High-quality hair building fibers are safe for daily use. Our formula is “anti-itch” and vegan-friendly, meaning it won’t clog your pores or irritate your scalp, even with consistent long-term use.
3. Are Finally Hair fibers compatible with Toppik or Boldify bottles? Absolutely. Our 57g refill bags are specifically designed to be a universal solution. You can easily refill shaker bottles from brands like Toppik, Xfusion, Boldify, and Caboki, allowing you to get premium results without the “brand name” markup.
4. Will hair fibers stay in if it rains or if I sweat? Hair fibers are resistant to wind and light perspiration due to their natural static charge. For maximum durability against heavy rain or intense workouts, we recommend using a Fiber Lock Spray to “set” the fibers in place.
5. How long does a 57-gram hair fiber refill bag last? Depending on the size of the thinning area and frequency of use, a 57-gram (1/8 lb) bag typically lasts between 3 to 6 months. This makes it one of the most cost-effective hair loss concealers on the market.
6. Can I go swimming with hair fibers in? While hair fibers are water-resistant, they are not waterproof. They will stay in during a light mist, but swimming or total submersion will wash them out. They are easily removed with regular shampoo.
7. Do hair fibers work on completely bald spots? Hair building fibers require some existing “vellus” (fine) hair to cling to. They work best on thinning areas or “patchy” spots. If an area is completely smooth and bald, the fibers will have nothing to bond to.
8. Can I use hair fibers with Minoxidil or other hair growth treatments? Yes. You should apply your topical treatments (like Minoxidil) first and let them dry completely before applying hair fibers. This ensures the treatment reaches the scalp and the fibers sit perfectly on the hair.
9. What is the difference between Keratin and Cotton hair fibers? Keratin-style fibers (like Finally Hair) more closely resemble the weight and texture of human hair, providing a more natural look. Cotton or plant-based fibers can sometimes appear “flat” or absorb moisture more quickly, which can lead to clumping.
10. How do I choose the right hair fiber color? We offer 23 natural shades, including hard-to-find Salt & Pepper and Grey tones. Always choose the color that matches your roots, not your tips. If you are between two shades, choose the darker one for a more natural-looking depth.

I’ve been using Finally Hair for almost two years now and I LOVE IT!!! I’ve used Toppik and a couple of other similar products. I have to say Toppik is also good but the cost is much higher than Finally Hair. I recently let myself run out of Finally Hair before I reordered and WOW CAN I EVER TELL A DIFFERENCE!!! I’m 65 and been a hair stylist since I was 16 years old…which means I know all the secrets to make my fine hair look fuller. But as I “gracefully grew older”….my hair grew thinner!! I started using first Toppik, then I switched to Finally Hair because of the great price….I have never been so pleased!! Now I am anxiously awaiting my supply of Finally Hair to arrive in the mail!!! I would HIGHLY recommend this product to anyone….male or female, who wants to make their hair appear thicker
SANDRA HEFNER (verified owner) –
This will be my second order, as I don’t want to run out. Everyone has commented on how my hair looks so much thicker lately. I’m so excited about the results. Highly recommend this product.
Martha Schober (verified owner) –
This product really works to cover thinning hair. I won\’t go out without applying it to cover my thin spots! I have used Toppick for years, but I like Finally Hair better not only because of the price but because finally hair doesn\’t clump as much as Toppik.
Rod (verified owner) –
Had purchased other more expensive brands in the past but this product, I give 5 stars… all other brands I would give 3 stars compared to this one. Highly recommend this product.
Calvin Rippee (verified owner) –
I was skeptical at first about using this, however I did order 1 bottle to start. After that I was hooked, no more bald spot on back of my head. Fibers blend in realistically. I will continue to use Finally Hair products over any of their competitors due to their quality and value. Thanks !
DM Casiano (verified owner) –
I used to use another hair fiber product and then found Finally Hair products. The products are equal to another brand that charges much much more. The service from Finally Hair is prompt and they answer any questions you might have. I will continue to use their product as long as they sell it.
Wilma Shaffrey (verified owner) –
I love this product. I’ve been using it for quite some time. I’ve even gotten my friends to use it. I don’t know what I would do if this product was no longer available. Thank you for having this product. It gives me confidence and I don’t feel embarrassed to go out without a hat.
David Willis (verified owner) –
This product works as good or better than similar products costing much much more. I’ve paid 2 or 3 times the price for other fibers from other companies with less favorable results. Will not make that mistake again.
Sharon Green (verified owner) –
Wonderful product. I have used other products and did not get the results that I did with this. Easy to use and looks great! Just sprinkle it on, use hair spray and ready to go! Highly recommend it.
Ann M. (verified owner) –
I’ve had challenges with other hair fill fiber products. They make my eyes and skin itch and burn. I have not had this challenge with Finally Hair fiber products. Allows me to use the product with both confidence and comfort…really critical to feeling good about the way my hair looks and the way my skin/eyes feel!
Ray Gwertzman (verified owner) –
I have been using your product for a couple of years now. I switched over from Toppik. Found your product much less expensive, better choice of colors and easier to order. Couldnt be happier
melvin b (verified owner) –
I received the package and it contained a coupon for $10 I will be shopping here again. Thanks for the fibers. Your product is better than another I tried I’m not going back because the price is great, they look natural just the effect I wanted. I became a pro with application and styling. This is the next best thing to having your hair back.
Wanda Robertson (verified owner) –
I’ve been using this product for a number of years, now, probably about 4-5, and always great coverage and the best price in the market!
Charlotte Mitchell (verified owner) –
I always had nice, thick hair, but a few years ago when I became a full-time caregiver, it began to thin due to the stress. When I discovered Finally Hair, my problem was considerably alleviated! It does not take a large amount to cover thin spots nicely, so a bottle lasts a long time. It’s great to be able to buy refill bags instead of having to buy a new bottle. I also let my hair go from “blond” to its natural salt and pepper, so can use both the grey and the S & P to my advantage. Thanks for a great product!
Thomas Stuart (verified owner) –
I’ve been using this product for years; wouldn’t use anything else. They always send the order quite quickly after reordering. The array of possibilities for color and shade are amazing and it will cover bald spots on top if you first spray, then apply, then spray again. I won’t stop using the fibers unless the company goes out of business! Thanks for being there.
Jennifer Helsel (verified owner) –
I always had very fine hair, but I had a lot of it! As I’ve aged, heredity has made my hair thin in the crown. These fibers are amazing! I’m 53 now and people guess my age around 37! They’re perfect and they stay put even while running and sweating. I mix two colors as I have blonde hair with chestnut lowlights. They’re so affordable that buying multiple colors is easy. Thank you FINALLY HAIR!
Adam Shpall (verified owner) –
This is an excellent product. I did my research looking for fibers of good quality at a good price and found a 3rd party site which rated fibers describe ‘Finally Hair’ as the Costco of fibers (due to the value).
I could not be happier with the results! I now have a full head of hair and it takes me less than the time it takes to brush my teeth.
I apply the fibers, pat down as instructed and add a little fiber lock spray. Thank you Finally Hair…and believe me, they did NOT pay me to write this!
Paul Zahn (verified owner) –
I have been using Finally Hair for a few years now. I usually mix 2 colors to get my salt n Pepper color. I asked Company for a free sample of another color and that seems good by itself. Good Customer Service!
Pattie (verified owner) –
I have always had thin hair someone told me about this and have been using it for years. I got cancer last year and oddly I didn’t go completely bald just weird patches, no one told me I should have shaved it short then. I used this product even more and I never looked like I had any less hair.
Christine (verified owner) –
Wears just as well as the more expensive brands and costs less than half the price— a keeper!
Montina (verified owner) –
Great product! Well worth the money. You can’t go wrong.
Deborah (verified owner) –
Saved the day. Product covers gray hair and bald spots perfectly. Until my own hair grows out I will continue to use.
Judy P. (verified owner) –
Even my husband’s friends don’t know he has a bald spot. He loves this product.
James V. (verified owner) –
Excellent service and product. I have been buying from Finally Hair since July 2022. Thank you.
Theresa P (verified owner) –
These fibers are so real looking. I recommend this brand. A lot less expensive and you get a lot more. Auburn mixed with brown (light and or dark) works perfect for golden brown hair color.
Charlotte M. (verified owner) –
I have been using Finally Hair fibers and holding spray for quite some time and love these products. My hair is beginning to thin due to age and the fibers cover thinning areas beautifully. I also want to give kudos to an employee named Mark. Your web site was not working properly, so I called to place an order. Because of the site problems, he could not enter the order and asked me to call back. However, before I could do that HE called me to say that everything was working properly and he could now take my order. This was, I believe, above and beyond normal customer service and he is to be commended for his custome
Marsha (verified owner) –
I really like this. The color is the same as mine and the coverage is easy to use. After putting it on my hair, I use a light spray of hair spray and it looks good all day. It doesn’t move away from the area I want it on, and doesn’t drip down my face.
