I just discovered Boldify, and I'm wondering, where has this been? I am currently going through medication treatment for hair loss, and lost even more hair at the start of the process. Boldify fills in all the gaps, while looking natural. It does not come off onto my clothes or pillow at night, and has lasted up to three days before I need to reapply. I even tried it on my husband's bald spot on the back of his head, and he was amazed, too. I was wearing a tape-in hair topper to cover thinning, which was expensive and painful to take out. This product has made all the difference! I have noticed that it the fibers will shift or come off if I wear a hat, which is my only issue. Otherwise, it has been a game changer!

This works wonders for confidence! It is gentle for my very sensitive scalp. Hair loss crept up on me: genetics, perimenopause, HRT troubleshooting = very fine hair made sparse. This powder quickly and easily fills in the gaps and makes my buzz cut look fuller. 5 stars.

Good stuff. The embarrassment of having your scalp show it’s almost eradicated by using this product. The only thing you must do is buy the correct color and they will replace the color for free if it’s not correct. Highly recommend.

These dark brown hair fibers are a lifesaver for my thinning temples and any little gaps that show when I pull my hair up. The color blends in perfectly with my natural hair and gives it a much fuller look — it’s honestly amazing how natural it looks once it’s in place.I’ve tried some other products and this one is my favorite!That said, the application can be a bit messy if you’re not careful. I learned to cover half the top of the bottle so less product comes out when I tap it into my hair — it gives me way more control and a softer, more natural finish. Once you get the hang of it, it’s totally worth it. A great confidence booster for anyone dealing with thinning areas!

I have thin, fine hair, and have had a wide hair part as long as I can remember. I have always been self conscious about it.This stuff makes my hair look so much thicker!! It’s extremely easy and fool-proof to apply and takes just seconds to shake the product on. And it doesn’t require a lot of product, just a few taps of the bottle and then I kind of run my fingers along my hair part to disperse it evenly.Once it’s on it doesn’t run or smudge onto your face, although I haven’t worn this during a heavy workout or rain yet, so time will tell on that.It also washes out easily in the shower and doesn’t leave a residue. Overall just wow! Really gives me more confidence. You can see the difference in the top picture with no fibers and the bottom picture with the fibers.

I was excited to try Boldify Hair Fibers since it is less expensive than the keratin fibers I have been using for ten years. I have mixed feelings about the product. It does provide fairly good coverage, but I have to use hairspray with this product. The fibers are more powdery, less loose fibers. The main complaint I have is the Dark Blonde shade looks beige-y, not yellow in the photos, so I bought it. I have NO natural yellow in my natural color so I thought this would work as well. In fact, this is a very yellow shade. When I searched the other reviews, I noticed other people commented the same.I used the product as-is and I think it works, although I am a little worried what others see in natural sunlight. So maybe I should say it seems to be okay in my bathroom light.My application may be part of the reason it helps. I use an orange (manicure) stick and section off very narrow strips to reveal scalp along the top of my head. I lightly shake, then continue. I am constantly covering the part I just covered with fibers with my own hair. I am VERY CAREFUL not to put the powders directly on my part line, and if I do, I use that orange stick (very fine) to gently scrape it off. So I am getting the fibers on the roots but covering with my hair, which I think helps with the mis-match color. I am disappointed that the color is so yellow. No one has yellow roots!The other brand I was using has much more "ash" or mushroom shades of blonde and I will probably go back to the more expensive brand both due to color and because I think their dimensional fibers work better for me. If there is another color that you could possibly use (light brown) it might work better unless you have very golden dark blonde hair.

This is an amazing product. My hair was thinning due to chemo. Had some patches where my scalp was really visible. Just a few sprinkles in the bare spots enabled me to go out in public without being self conscious. It's really not noticeable - just blends in so well. People thought I hadn't lost any hair. Just a little sprinkle will do. Would work for anyone with thinning hair, regardless of the reason.

This holds in wind and in rain, holds up to sweat. Sometimes I sleep with it on and it holds and stays covered. It even olds when I wear a cap. This is a great product!

Je suis vraiment impressionnée par ces fibres capillaires BOLDIFY ! Dès la première utilisation, j’ai constaté une différence incroyable.Couleur parfaite : La teinte est parfaitement assortie à mes cheveux et se fond naturellement sans démarcation visible. Contrairement à d’autres marques que j’ai essayées, celle-ci ne donne pas un effet artificiel.Format économique : Le flacon de 28 g est un excellent investissement. Il dure beaucoup plus longtemps que les formats standards, ce qui est un vrai plus pour un usage quotidien. Une petite quantité suffit pour obtenir un bon résultat, donc pas besoin d’en mettre énormément.Packaging élégant et pratique : Le design du flacon est moderne et facile à manipuler. L’application est rapide et efficace, sans faire de dégâts partout.En quelques secondes, mes cheveux paraissent plus denses et volumineux, et le produit tient bien toute la journée sans s’effriter. J’avais quelques doutes avant de l’essayer, mais maintenant, je ne peux plus m’en passer ! Je recommande sans hésitation à ceux qui recherchent une solution rapide et efficace pour masquer des zones clairsemées.

Buying Guide

When it comes to finding the best hair thickener, it can be a challenge to find the perfect product for you. In this guide, we will discuss the most important factors to consider before purchasing a hair thickener. First, understand the four types of hair thickening products: polyester, keratin, cotton, and synthetic. Polyester fibers are usually made of a fine synthetic material that closely resembles real hair. Keratin fibers are made up of natural proteins that are similar to the ones found in human hair, giving a more natural, shinier look than polyester fibers. Cotton fibers are made from natural cotton fibers and are best for those with sensitive scalps. Synthetic fibers are made from a combination of polyester and nylon fibers. These fibers are more affordable than natural fibers, but offer a less natural look. Once you have chosen the type of hair thickener, select a product that best matches your hair color and texture for a seamlessly natural look. Hair thickening products feature different levels of coverage. Choose one that provides the level of coverage you desire. Since this is a personal investment, consider whether the benefits of the product match up to the price. Last but not least, check the ingredients of the product to avoid scalp irritation. If you have a sensitive scalp, it may be best to use a hair thickener that is 100% plant based. Taking these points into consideration will lead you to the best hair thickening product for your needs.
