TLDR: Toppik Hair Building Fibers Review

Toppik Hair Building Fibers - Keratin Fibers | Toppik | Toppik Canada

Product Description

Toppik Hair Building Fibers is a hair loss product that is meant to transform thinning and fine hair in seconds. 

The fibers are even made from natural Keratin, which has an internal and external structural protein to protect hair and keep them healthy.

Other Keratin is extracted from lower-grade sources, such as fish bones, hooves, and nails. The Toppik, however, are derived from premium fibers. 

This is why you’ll notice a great difference in fiber appearance and texture.

Methods to use Toppik

There are two methods to use the Toppik Hair Building Fibers. The first method, ideal for covering large areas of hair thinning, is by using the sifter cap on the fibers bottle. 

All you need to do is shake the fibers and put them directly into the thinning hair. Then, pat the fibers to evenly distribute them into your scalp.

The second method is best for covering hairlines and small areas. For this application, we suggest that you use the Hairline Optimizer or Spray Applicator. 

Lots of customer reviews we came across online attest to the efficacy of Toppik Hair Building Fibers in making them look younger.

Potential Toppik hair fibers side effects

Toppik hair fibers are generally safe. However, we cannot scratch out the potential side effect of using this product for the long term. 

One of which is developing an allergy associated with dyes. But this one is easy to solve.

To see whether your skin will react to the product, we suggest you do a patch test on a small area of your skin first for 24 hours before you start to use them on your hair. 

Do not apply if it causes redness, irritation, or itchiness.

We also notice that Toppik contains ammonium chloride. This non-organic ingredient is used in fertilizers and to add flavor to certain licorice (plants). 

It also works as a thickening agent in dyes so compounds stick together. Ammonium chloride is safe to use topically but may be hazardous if significant amounts enter the body. 

Repeated exposure over time may cause ammonia poisoning that can cause allergies, irritation, irregular heartbeat, irregular breathing, and muscle spasms.

What Do People Say About it?

hair loss product


 Toppik Hair Building Fibers have an above-average rating on Amazon on the category of hair-building fibers. One Amazon customer said, “I’m speechless – this stuff works, plain and simple. I’m a 31-year-old male, and I’ve been losing a lot of hair the past few years. It’s definitely a bummer, but I’ve learned to live with it. 

[The] only problem is that I am getting married in four weeks, and if I can help it, I really do not want my balding head to be forever documented in our wedding album…This probably isn’t meant to be a permanent solution to conceal hair loss, but shoot, if you wanted to, I don’t see why you couldn’t use this all the time.”

Another review reads, “Like many 60-year-old women, I’m finding I have more space between my strands of hair than I would like. I sprinkle this on in a few seconds after my hair is dry, and it gives it a much fuller, thicker look. No more “bald spots,” and it doesn’t come out on my hands! Lasts until the next shampoo.”


Tiffany D. Brown shared on YouTube her thoughts on Toppik Hair Building Fibers. She said, “I would definitely recommend the applicator. I do love the smell of the hold and spray as well. It doesn’t feel very sticky…Life, pregnancy, hormones, and all that. How it made [my hair] thin in this area (frontal region) and I really love the way that now you can barely even tell. It’s crazy how well it felt. Instead of using a brush, I like to just use my fingers and kind of smooth it in. So, I have a little bit more control that way.

I switched from dark brown to black and black was what I decided to stick with. It’s definitely something [to use] if you’re having to boost some confidence as you’re having some thinning or shedding.” 

Another review is from Lylah Kay, who considers the Toppik Hair Building Fibers product as a game-changer for her. “[It allowed] me to go about my life pretending that I have no hair loss issues,” she wrote in the video description box.

She also mentioned in the video, “Does it actually work? The product is meant to attach to the hairs on the scalp, creating fuller-looking hair. It’s been a huge game-changer in the cosmetics and hair loss industry… I personally have been using Toppik for about three years now and will likely continue to use it as my hair loss continues. For the pros, it’s easy to use. You simply sprinkle it on the area that you’d like to conceal. It helps hide thinning and balding spots in most cases. 


One Reddit user shared, “[I] had a barber spray some Toppik in my hair after a cut a few months ago. It should probably work well for you, but you will need to reapply every day. I noticed it was somewhat difficult to get out of my hair in the shower, but I was able to.”

Another Reddit user shared his experience with the Toppik Hair Building Fibers. “I use toppi[k]. I’ll try to keep this short. I have a high fade cut and I use Toppik just on the top of my head where it’s thinning. Then use hair spray to retain everything. I do this every 2 days. You need some hair for this product to work correctly. If you have a defined bald spot you can see the powder on your scalp. It helps a lot, but there’s some trial and error while you learn how to use it effectively.”
