Amazing!
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!

Female hair loss is less heartbreaking with this
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.

The best product to cover bald spots
I was hesitant to try this product, but I am so glad I did because it’s giving me a lot of confidence and freedom with my hair back. I am dealing with a lot of bald patches in the back of my hairline and wide part patches due to an immune skin condition and this really covers it. It doesn’t feel gross, it doesn’t come off on your fingers, It feels and looks natural. I don’t notice it on my scalp and I feel like I can toss my hair without worrying about my bald spots showing.

Excellent product
Excellent product definitely works! Does not stain definitely stays on your hair. I wash my hair every fourth day so this will definitely last me a long time…..

This product is a game changer!!
BOLDIFY IS A GAME CHANGER with one caveat: wish there was FDA approval on this product. I'm a female Asian-American in my 30s, so I have always had fine, thin hair. The worst part for me is this: the skin of scalp shows (no matter how much volume I try to put in my hair by styling/blowdrying), and I feel the fine/thinness is getting more prolific throughout the years!! In photos, my head/hair always has a white spot showing the scalp - which you can see from my first posted photo - plus, I'm also a professional musician so on-stage lights really exacerbate this issue. Throughout many, many years, I've asked hairstylists to part my hair differently and create more volume (layers!), but it never fixed the issue of having my scalp show. Having black hair and a really light-toned scalp is THE WORST. How could I possibly look like a professional? In desperation, I started looking up products on Amazon and came across Bolidify. I've been concerned about putting liquids (i.e. sprays, like the old Bumble & Bumble product I tried over a decade ago) on my scalp because I don't want my skin to absorb toxic chemicals* (more on my slight concern about one of the ingredients below.) When I read that Boldify are actually fibers, I decided to give it a shot. This product's goal of making your hair look thicker WORKS!!! The tiny fibers are dispensed through holes similar to a baby powder dispenser, and my method to apply is simply by holding it at an angle and tapping the bottle. Just a bit of advice: When you "pat it down" as the instructions direct, the fibers will rub off on your fingers, so I just apply by tapping, then use my hair spray (it's a Bed Head hard hold hairspray, which probably IS being absorbed by my scalp, but I'm digressing). The look stays throughout the entire day, and I've even fallen asleep with this product in my hair, and it's still passable the next day. If someone were to very closely examine my scalp (as in, look at my scalp from less than a half a foot away), I'm sure they'd see a tiny bit of strangeness, but no one is ever going to be doing that. As you can see from the second photo, it's very passable. My only hesitation in giving it a full-blown 10 out of 10 is the lack of FDA approval and that it's manufactured in China. One of the ingredients listed (fourth out of five) is DMDM Hydantoin - it's a formaldehyde releaser to combat the growth of bacteria in cosmetic products and I wish it listed how much is in there (according to some research, it is not considered unsafe if there is less than 1% of it in a product). I read that the shampoos by Boldify are FDA approved but want to know why this product isn't approved. Would love a response by Boldify on this matter. All being said, using this product has absolutely boosted my confidence. A few weeks ago, I had a major performance with professional photography taken, and the former issues with my scalp showing were non-existent because I used this. This product is indeed a game changer in covering up the scalp and making your hair look fuller. I WISH I had this product throughout the past ten years. Ever since buying this over a month ago, I've used it daily (I'm not sure how much of it I have left, so I can't say how long this bottle will last/hence, the true value for the money). I highly recommend if you're not worried about the FDA approval.

Rubs off
While the product does a great job in covering the thin spots on your head, it will leave deposits of color on your pillow or anything your head rubs against - think about the white blanket that rests over the back of your chair and you lean back. Or if you scratch the area (or rub it), you get a bit of product under your nails or on your hands. This is even after you read the directions and use hair spray as recommended. Will only use this product sparingly now and will look for possible alternatives for daily use.

I LOVE IT
I was so scared that I wouldn't like it but I LOVE IT! I bought the sample packs and the grey colors are just perfect. I can use both grey and dark grey and it really does fill in bald spots. It even makes my natural salt and pepper hair look prettier with more highlights to it. I will buy the full size grey and dark grey for sure! The samples are a nice size! They will last me awhile. So impressed. I saw a few reviews where it looked kind of cakey but that is only if your scalp is dry. Buy this! Good price too. Just as good as the expensive brand. Very happy

This product works very well, better than topping. It stays put all day if you use a little bit of hairspray it’s definitely a game changer for thicker, fuller hair.
