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.

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…..

Perfect for cowlicks & slick buns
I have a stubborn cowlick in the back of my head, and whenever I put my hair into a slick bun, gel alone was never enough to keep it from separating. I decided to try these fibers and it completely solved the problem. Now I apply a small amount directly to my scalp where the cowlick is, use a brush to blend it in, and then apply my gel over it. My slick buns stay smooth, firm, and in place ALL day. No separating anymore. It also works amazing when I wear my hair down. I have naturally curly hair and the fibers blend in perfectly without looking fake or heavy. This has been such a game changer for styling and control. Highly recommend!

Dark Blonde Looks Yellow, Otherwise, a Decent Product
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.

Works Like Magic
Match your haircolor as closely as possible. I am very satisfied with the results. It is totally undetectable, even by my spouse who towers over me by 10 inches. Easy to use, no pillow marks or smudges. There is a link to the mfr's how-to video in the box.

Great Coverage for Thinning Spots — Just Takes a Little Practice
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!
