Why am I discussing the best hair loss concealers (also known as hair fibers) on a hair loss cure site? Largely because of my own great results from trying out Toppik hair building fibers in the past. See the bottom of this post for my story.

When I first wrote this post, there were only five or so well known scalp concealers in the market. In 2025, there are well over twenty. Further below, I list the 10 most popular hair loss concealers in the world.

The Best Hair Loss Concealers in 2025

While far from being a permanent solution, hair loss concealers are a great camouflage option for many people. Best results and greatest satisfaction will be attained by those with minimal totally bald patches on their scalps. However, there are many videos on YouTube where hair building fibers are also helpful for people with extensive hair loss. Customer reviews of virtually all hair loss fibers and bald spot concealers are generally favorable. Women are also often very pleased with hair loss fibers.

Below, I list and compare the most popular hair loss concealers out there based on the number of Amazon reviews. If there are many versions of a product that are sold separately, I only consider the most reviewed one. Keep in mind that there are many fake reviews in the online world. You should pay most attention to the ratings that come from verified users who have reviewed a diverse range of products for at least a few years.

Virtually all of these best hair loss concealers are deemed to work well for people of all ethnicities, as well as for both men and women. Just make sure to pick the right color for your particular hair type and check that the material is waterproof.

Note that hair loss concealers come in three types:

1. Fibers Concealers. The most popular type.
2. Liquid concealers. Usually in a spray form, though creams and gels are also available.
3. Powder concealers. Similar to makeup and camouflage products.

Toppik Hair Building Keratin (Wool) Hair Fibers

This is by far the bestselling hair loss concealer product on Amazon with almost 70,000 reviews averaging 4.3/5 stars at the time of updating this post in 2025. As discussed earlier, I used this product (12 gram version) and was very pleased with it. However, I have never tried any other hair loss concealers to make a solid comparison. Be careful that you pick the correct color (nine choices) and size options before buying Toppik. As you can tell from the reviews, a lot of women love this product too.

My own salt shaker type container of Toppik was made in the US by a company called Spencer Forrest. The latter also used to make another wool based keratin hair fiber product named XFusion in the past. The main ingredients in Toppik are keratin, silica, ammonium chloride and DMDM Hydantoin (plus added artificial colors). The keratin is sourced from wool according to the Toppik website’s FAQ section. Each small bottle will last for a month or two depending on extent of daily use and extent of balding area. Note that I did not use a Toppik brand FiberHold Spray to cover bald spots. The hair concealer spray is recommended for concurrent use with the fibres for best results. Neither did I use the Toppik Spray Applicator that is supposed to help make the application process more precise.

Boldify Hair Building Fibers

Boldify hair fibers have become extremely popular in recent years. A few years ago, I did not even know this company’s name. The product has rapidly aquired an insane 30,200 reviews averaging 4.3/5 stars as of 2025. It now competes with Toppik when it comes to the most popular hair loss concealers or fibers. Customers claim that Boldify is easy to use and apply. The smallest size option is 0.42 fl oz (12g) and at $15, it is similarly priced to Toppik. In comes in shades black, auburn, brown, blonde and grey. For even more scalp coverage, Boldify hairline powder may also be a good option for your needs.

Caboki Natural (Gossypium Herbaceum Cotton) Hair Loss Concealer

I have seen Caboki ads all over the internet during the past several years. On Amazon, the product has 3,400 reviews averaging 4.4/5 stars as of today. The great thing about this product is that it seems to be totally natural per the list of ingredients: “Moroccan Gossypium Herbaceum and mineral-based colorants (natural iron oxide)”. On the company’s website they are currently offering a free sample, though you pay for shipping. The manufacturer is headquartered in the US. Caboki is offered in seven different color choices. It seems like the two most compared hair loss concealers by hair loss consumers are Toppik versus Caboki.

Febron Bald Spot Concealer Filler

Febron is yet another newly popular name in hair concealment products. The Febron hair volumizing fibers are considered to be natural and undetectable. The complimenting Febron FiberHold Spray will lock the synthetic fibers in place and not leave any residue. Customer ratings average 4.4/5 stars based on 2,970 reviews as of 2025.

Hair Illusion 100% Natural Human Hair Fibers

Hair Illusions’s very unique and interesting 100 percent natural human hair fiber product currently has 2,680 reviews averaging 3.9/5 stars. The product has eight color options for both men and women. However, on the company’s website, they do not have much information on where the human hair is sourced from. Hair Illusion is based in the US, but no actual address is shown on their website.

Elevate Hair Fibers

A newer brand named Elevate has quickly racked up almost 1,400 reviews for its natural and undetectable keratin based hair building fibers. They only come in two colors: black and brown. The current average rating is a solid 4.4 out of 5 stars based on almost 1,400 reviews. The company also sells a 2-in-1 kit and a 3-in-1 kit.

DermMatch Natural Botanical & Mineral Based Hair Loss Concealer

DermMatch has been one of the 3-4 most popular well established products out there when it comes to the best hair loss concealers. Unlike most of the other products listed in this page, DermMatch is actually a scalp makeup product and does not contain fibers. On Amazon, the product has just 1,450 reviews averaging 4.2/5 stars, though the prior version of the seller page had many more reviews. Edit: Currently unavailable on Amazon, although the company’s website is still active. DermMatch is available in eight different colors. Each disc container lasts for an average of eight months and contains a very large 40 gram quantity. Ingredients are all natural and include various emollients and botanicals. The US-based company that makes this product has been in business since 1992.

Nanogen Fibres

Nanogen is one of the most popular hair fibre brand in the UK. Several readers of this post also commented about this highly rated product. On the Amazon US site, it currently has 1,860 reviews with an average rating of 4.2/5 stars. Nanogen uses “color lock technology”, which means that there will be no staining to your skin or clothing. The product is made from 100% natural keratin and contains no parabens.

Infinity Rayon Based Hair Building Micro-Fibers

As of today, Infinity hair fibers for women and men had 900 reviews averaging 4.2/5 stars on Amazon. I could not find anything about the location of the company on the company’s website. They do have a FAQ section and easily visible contact options. The ingredients of Infinity are listed as “Rayon; may contain: CI 47000, CI 14700, CI 42102.” The latter three are various artificial colors. Infinity comes in ten color options.

Cuvva Keratin Hair Fibers

While several of the earlier mentioned keratin fiber products were made from wool, US-based Cuvva does not disclose that information and just states the following on its site: “Cuvva hair fibers are made up of pure, organic keratin protein, just like all human hair. They are charged with a precise level of electrostatic energy in order to form the maximum magnetic attraction to your thinnest hair. There are no harmful chemicals or additives whatsoever.” Available in 12 colors on Amazon, with 560 ratings averaging 4.1/5 stars at the moment.

Other Hair Fiber Scalp Concealer Products

A number of newer companies selling hair thickening fibers and scalp concealers in the US have garnered an influx of reviews recently. In some cases, this is due to concerted efforts at advertising and using social media. Among the major keratin based hair thickening fiber brands that I have not covered above include Luxe, SureThik and Thick Fiber.

Art Naturals (US) used to sell a unique cotton based hair fiber product in the past. I no longer see it on Amazon or Walmart at present, nor on the company’s website. It was similar to Caboki, with the main ingredient being a type of cotton named Gossypium Herbaceum. A UK based company named Gofybr sells hair building fibers on its own site that are also made Gossiypium Herbeceum.

When it comes to hair loss concealer powders, one of the most popular products is Joan Rivers Great Hair Day fill-in powder. L’Oréal and Clairol also sell very popular root touch-up and cover-up sprays and powders.

Hair Loss Concealer Colors

Hair loss concealers typically come in the following colors, listed in order of darkest to lightest:

• Black.
• Light, medium and dark brown.
• Red.
• Grey.
• Silver.
• Light, medium and dark blonde.
• White.
• Auburn.

For African American hair, note that there is also the Bigen hair dye treatment.

My Experience with Toppik Hair Building Fibers

In 2016, I got a haircut and really disliked seeing an increasingly visible small bald spot in my receding hairline. The frontal scalp region frames ones face, and my thinning hair and bald patch in that area was annoying.

Therefore, for the first time in my life I decided to try out a hair loss concealer (Toppik hair building fibers) seriously. I was doing this for largely experimentation purposes, with no desire for long-term daily usage.

I was not keen to try out a hair loss treatment such as scalp micropigmentation, since I prefer longer hair. Note that while scalp micropigmentation and tricopigmentation can both give the illusion of longer hair, they are still in 2-dimensional format rather than 3-dimensional format.

Initially I had reservations about my experiment due to possible hair fiber side effects and other issues such as: scalp rashes and itchiness; a messy spray type application process; rain and wind causing some of the powder or hair fibers (if not waterproof) to run onto my forehead; the color of the hair loss concealer not exactly matching my natural hair color; the dye discoloring my pillow; the fibers not sticking to my hair; and finally, I did not want to become addicted to the product! Nevertheless, I decided to proceed.

I chose to try Toppik because it was one of three popular highly rated products (the others being Caboki and Dermmatch) that I had heard of over and over for many years. Make sure to see the comprehensive list of the best hair fibers (also spelled “fibres”) and concealers based on ratings and reviews further below.

For around five consecutive days after my haircut, I sprinkled a small quantity of the concealer onto the small barren patch of my frontal scalp region. I did this every morning after a shower, once my hair was totally dry. I was quite impressed at the ease of the process of applying Toppik. It was not messy whatsoever and had few disadvantages other than not being entirely waterproof.

More importantly, the results were excellent. Just a few shakes/sprinkles of Toppik black were sufficient to totally cover my small bald region. Moreover, the product never came off during the course of the day (even in significant wind) unless I happened to sleep on a bed and rub my scalp against a pillow for a significant period of time.

Even then, the pillow did not become dirty. The hair loss concealer fibers just came off without discoloring anything they fell on. Showering the next day removed all the product from my hair, without getting the bathtub dirty. All in all, I was quite impressed with Toppik and therefore decided to write this post.

Do note that while the company’s website states that rain will not remove the fibers from your scalp, I have my doubts. Many reviewers suggest that scalp concealers for thinning hair are never fully waterproof. You probably want to avoid heavy rain when using Toppik or any bald spot concealer products.
