These fibers are perfect for filling in areas of hair loss. I got them for a family member with some thinning areas due to medication related alopecia. I sprinkle them on to clean, dry hair and use the included brush (bristle side) to blend them in. Once blended they are virtually undetectable! The color match is perfect. Great for adding volume underneath layers as well, functioning in much the same way as a dry shampoo. These fibers stay put all day, even in high heat, humidity, or when it rains. They shampoo out fairly easily as well. These don't run down the face or neck at all. I tried another major brand of hair fibers in the past that are about 30% more expensive. Boldify works just as well, I can't tell any difference in blendability or staying power. This product is the better value. Boldify has been a lifesaver for this person while their hair fills back in. Definitely recommend, along with the Boldify hairline powder.

I use this bc my hair is thinning but low key, it’s better than any dry shampoo I could have ever thought of using. Let me tell you why. Dry shampoos have the tendency to leave a white cast on dark brown to black hair unless it’s colored and marketed as such. After I used this post partum, my hair grew back and I was trying to find a way to preserve my hairstyles because my hair is curly and I like to heat style, so I want it to last a few days. I bought so many of them and kept coming back to my batiste volumizing one which definitely leaves a white cast. I would use it day 1 and then touch up, but after about day 3, I couldn’t hide the grease any longer so at that point depending on curly or straight it would either be a ponytail for an extra day or a wash day. Fast forward to some recent stress and hair loss and I’m reaching for this again to cover up some thinning and that’s when I realized I was on day 5, hadn’t used any dry shampoo, and my hair still looked as good as day 1. I went up to 7 days and it still looked good. It even worked with my curly hair that had product in it. It didn’t mix with any of the other products for any weird texture or anything. Will definitely be repurchasing and replacing for my dry shampoo.

First, let me say I just started using this type of "powder" a couple weeks ago to coverup my VERY thin hair and I am so excited with the results. I decided to try BOLDIFY rather than my other brand becuse I wanted the brown ash color and becuse it is a little less in price than the other product I have used. I found that BOLDIFY sprinkles out very quickly from the bottle and is a little less binding to my hair. This is why I have made it a 4 star. The color was great. I am just going to have to get used to the quick sprinkle if I want to keep using this product. I had powder all over my sink and down on my forehead with my first try. But I am thrilled with the way my white scalp disappears and it looks like I have my beautiful hair again. I totally recommend using this type of product if you have thin hair. And Boldify was good considering the lower price and color options. It does take a little getting used to. I also suggest getting a hairspray meant to hold the powder a little longer. Both brands I have used mostly stay on my scalp until the next wash. I just have to do a little touch up each day. I am posting some before and after pictures. My very recent new drivers license picture is horrible. So much baldness. The picture with the top of my head tied in a bun is after sleeping with the powder and no freshen up. You can see it stays pretty well.

Absolutely love this stuff. And for the price it's so worth it. If you have thinning hair. Regain your confidence with this product. The color matches are spot on. Good texture. Looks natural. Great quality. Super easy to use.

This item is simply outstanding and does a fantastic job of covering my gray roots and adding volume to thinning patches on my head. With occasional dye and properly matching the Boldify to my hair color, I am able to enjoy a much better appearance with minimal effort. It is easy to apply and matches my hair great.

***UPDATE: The seller contacted me and promptly provided me with a full refund! Unless the formula changes, I will not buy this powder again. HOWEVER I really love the "BOLDIFY Hairline Powder - Root Touch Up Hair Color /Bald Spot Concealing Hair Powder for Women & Men - 48-Hour Stain-Proof" that comes in the little round pot with a sponge for applying and will stick with that. One star for this powder, but 5 stars for the customer service and 5 stars for their other product. I will continue to purchase from this company. =========================================================================================== These hair fibers were a huge disappointment. I have some thin spots and hoped this would help to conceal. Wrong! They did not stick to my hair clean or unwashed. They left a powdery mess in my bathroom, and when applied to my hair the fibers came out everywhere when brushing (came out in some clumps and dust) or even just patting my head. I tried on clean hair and I tried with hairspray which made it look like I had dust stuck to my hair. I love the BOLDIFY Hairline Powder - Root Touch Up Hair Color /Bald Spot Concealing Hair Powder for Women & Men - 48-Hour Stain-Proof and thought since that worked so well that these would be good as well, but these fibers are disappointing. The fibers also stick well to themselves making big clumps. If you shake the can, it sounds like there are pebbles in it. I have used other brand hair fibers before (Topik) and they are ok, never had that type of problem with them. I like the BOLDIFY spot concealing powder the best and will stick with that.

Wasn’t sure how well these would work. Got the sample pack for my mom. She has Snow White hair but it’s 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!
