Works great!
Wasnât sure how well these would work. Got the sample pack for my mom. She has Snow White hair but itâs thin. These fibers really make her hair look thicker than it ever has. Easy to apply and last until she washes her hair. Even after super hot days and sweating. Fingers are still there. No strange texture just full looking hair. The white is truly white. Add this if you want to amp up volume to thin hair. Really works!

Great product and service
Excellent coverage! The fibers are very fine, which makes application easier and looks more natural! Also the customer service is greatâ the color match guarantee is just that! I initially got the wrong shade and after contacting them, a few days later I got the correct shade at no additional cost!

Temporary but achieves the goal. ð
Let’s just say it’s a very timely process to figure out why your hair is thinning or why you’re getting bald spots. Then there’s a whole other process for treating and fixing it.Problem is, you’re going on vacation. Or on a date. Or to a fancy event. Or to a family event even.This product is fantastic for immediate, temporary results that make your hair look fuller… Especially in those problem areas.This product is literally for, I don’t want to have bald spots in public. This is not a spray. It’s not just spray painting your scalp (lol) although I was so desperate I was ready to try that.This is a powder and from what I understand, it’s like tiny little hair fibers that bind to any existing hair.Give a little shake, like you’re seasoning your head. Lolð Easy peasy.I have not encountered rain while using this product so I will not speak to that. I do know that it comes out with shampoo and you’re back to being little miss baldy (like me ð¨ lol).I have not had it come off on my pillowcase.I think most people recommended hairspray after seasoning, but I don’t like the way hairspray feels so I haven’t done that. Still seemed to work pretty darn good.Literally, like seasoning your head with hair. Lolðððð

Pleasantly surprised!
Saw this on a random FB Buzzfeed Prime Day product roundup post so I didnât think much of it but was pleasantly surprised how great this works for me! I have jet black hair so the color matching was easy. I have severe thinning on my crown and this does the trick! Matches my hair texture well which I was worried about as I am mixed race (Black and Korean) but it blends very naturally! I am also a person who sweats easily from my head when working out and nothing runs or transfers! Highly recommend, Iâll definitely be buying again!

Works surprisingly well!
This product is less than half the price of the more well-known Toppik which is what led me to try it out along with the fact that there is no ammonia like Toppik contains in its much longer list of ingredients.It was very easy to apply by just shaking it over the thin spots after already styling my hair and patting it into the hair as they tell you. The fibers do a good job at naturally clinging to and between the hairs you have. A quick spritz of hairspray helps secure the fibers in place and wiping any extra fallout from your face or counter is painless. I haven’t had any noticeable fallout going about my day and nobody has clocked that I’m using the product. They would have to be pretty close and specifically looking for it.I did accidentally order a too light of a shade and it looked like dust in my hair, but their customer service was super helpful and refunded me so I could reorder a better match and this one was right on the money. It made a HUGE difference and I would definitely recommend you go darker if you are between shades like they say or maybe just goa shade darker anyways. I have a medium cool toned brown color and the Ash Brown worked perfect for me. This is one of the few shades that other hair fiber companies don’t have. This brand definitely seems to have the most.Unfortunately I have thinning at my hairline which is perhaps not the best use for hair fibers as it is much more likely to be noticeable right in the front if you have a lot of scalp showing through, so I have to try and get the right balance of improving the thickness without getting too much falling onto my scalp. They do not offer a spray applicator, but they are available from other providers and I feel this would definitely help for hairline applications.For crown thinness it works much better but I would caution against using it in completely or near bald areas as it can only do so much and relies on sticking to hairs you do have. I’ve seen a bunch of videos of people with barely any hair using hair fiber products and they never zoom in close…I can imagine that’s for a reason. Without hair, it’s just going to look like astroturf on your scalp.

Sprinkle On Powder
I purchased the medium/dark brown kit to figure out which color would work best for meWas impressed with the different shades and quickly figured out the one that I preferThese are smaller in size, but they are a good size. Plenty to try out to find your perfect shade.Unfortunately the powder looked a bit strange on me. Almost like specks on my hairline.My need is for my bangs area.Farther back I believe it wouldâve looked better/different.It wasnât hard to apply but for my bangs/front of my head/face hairline area, I believe the powder that you press on would work better.

Covers well and stays powdery.
Works well. Not gummy and does not solidify.Covers up pink skin that shows through on white hair.

Je suis vraiment impressionnée par ces fibres capillaires BOLDIFY ! Dès la première utilisation, jâai constaté une différence incroyable.Couleur parfaite : La teinte est parfaitement assortie à mes cheveux et se fond naturellement sans démarcation visible. Contrairement à dâautres marques que jâai 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 dâen mettre énormément.Packaging élégant et pratique : Le design du flacon est moderne et facile à manipuler. Lâapplication 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 sâeffriter. Jâavais quelques doutes avant de lâessayer, mais maintenant, je ne peux plus mâen passer ! Je recommande sans hésitation à ceux qui recherchent une solution rapide et efficace pour masquer des zones clairsemées.

Ich habe dünnes Haar das vor allem am Scheitel sehr Licht ist. Ich verwende Boldify um die durchschimmernde Kopfhaut an dieser Stelle zu kaschieren. Es ist unauffällig und natürlich ich liebe es. Keiner fragt mehr warum mir die Haare ausgehen und ich sehe viel gepflegter aus.
