What is a hair filling fiber?
As much as we might try to wish it away, hair loss is a very real problem faced by many men. The causes can be varied, often genetic, and though procedures have come a long way over the past few years a hair transplant is still a big decision to make.
Luckily there is a great alternative to help hide your bald spot and conceal hair loss – hair fiber powder.
What Are The Hair Fibers Made From?
Usually coming in a powder or spray, there are three main types of fibers for men to choose from. Cotton fibers are the best for sticking to bare skin and covering bald spots, but may not cling well to your own hair. Natural human hair fibers will most closely replicate the look of your own, and blend in well to your existing hair. Keratin (the protein that our hair, nails and skin is made up of) is most popular and will bond well to strands as the fibers have the same molecular structure as your own hair.
What To Consider When Choosing A Hair Loss Concealer
Just like the majority of men’s grooming products, it’s important to think about what factors will make a hair concealer work well for you. If you have sensitive skin, you may find a natural human hair fiber will be less likely to irritate your scalp and cause itching. If you need a bald-patch concealer that won’t come off in rainy or humid weather, you’ll need one with a high resistance factor. What are you starting with? If you want your thinning hair to look lustrous and thick again, choose a hair filler powder that will blend in well with your hair. On the other hand, if you are looking to conceal a larger bald spot, you will do better with a fiber that sticks well to skin. Our guide to the 10 best hair loss fibers takes the guesswork out of hiding your bald spot:
1. Nanogen Keratin Thickening Hair Fibers
If you want to wear your hair fibers overnight, the color lock technology in this Nanogen keratin powder won’t cause awkward stains on your pillows and bring up uncomfortable questions. With a kinetic strip on the sleek, modern packaging, the keratin fibers are given a static charge to bond with your hair before reaching your scalp. If you also want to use other products to battle hair loss, these fibers won’t block your pores and decrease the effectiveness of topical treatments. Helping men and women to hide hair loss for over 10 years, these fibers for hair loss will give your new thick look staying power.
2. Hair Genetics Advanced Keratin Hair Fibers
This hair loss spray cover-up is one of the best hair fibers for those who like to use products on the go. Chuck this in your gym bag for an easy shake and spray application without mess.

Wind and rain resistant, Eclipse Instant Hair Filler can stay in place for up to a week to hide hair loss. The only downside to the product is the lack of natural ingredients, so may not be the right choice for men with sensitive skin.
4. XFusion Keratin Hair Fibers
Feel self conscious that your bald patch concealer will slip down your scalp when you get sweaty at the gym?

5. ELEVATE Natural Hair Perfecting Fibers

6. Toppik Natural Keratin Hair Fibers
Though the Toppik hair fibers only come in nine shades, if you’re looking for a hair loss concealer that will cover gray roots to keep your color looking fresh then this is the best powder to go for. The colorfast formula means you don’t have to worry about the hair loss concealer melting down your collar in hot weather, while the statically charged fibers will intertwine with even very fine hair. Made of high-grade keratin, this toppik hair loss concealer is one of the best options for men and women with short, sleek cuts.
7. CUVVA Keratin Hair Fibers

8. LUXE Professional Hair Fibers

10. BOLDIFY Hair Thickening Fibers
One of the most popular hair fillers for men, it’s easy to see why so many people are satisfied with the results that this BOLDIFY thickening powder provides. With a wide range of 100% plant-based colors, it’s simple to match this hair loss concealer to your own hair tone for a really natural finish. With their color match guarantee, you can easily swap the product for another of the 15 shades to make sure you get the right one for you. The clump-free formula and follicle mimicking molecules will closely match your own to blend into your hair and bond tightly for maximum staying power. If you like your hair to look healthy and glossy, as well as thick, this will add a good level of shine, unlike some other powders which have a very matte finish.
What To Remember When Choosing And Using Your Fibers
Make sure you take time to get the shade that best matches your own hair color. If the shades don’t match the concealer will look unnatural and it will be obvious that you have used a filler. If you can’t find a suitable color, try mixing shades to create your own unique tone – but make sure you use the same brand and type of fiber. For a more natural look, pat your head in between applications of fibers or use a soft brush to gently brush the product through your hair. If you don’t want a filler that will cause stains on your clothes, or slip off in the elements, choose a hair fiber that is wind and rain resistant. Some fillers will stick better to a bare scalp so are better for concealing larger bald spots, but if you want to make your existing hair look thicker, use a statically charged keratin fiber that will stick to your own hair.
