Hair Building Fibers , Hair Loss Concealer Black 57 Grams (2 oz) Minute Refill are compatible with all hair fiber applicator bottles

These are very good and affordable, since the packaging is cheaper, I’m sure that’s why, but it is just like the higher cost ones, you just need the correct applicator

I ordered the blonde color. Most likely I will have to mix another color into it to get the best result. The blonde is like a medium to dark ash blonde. No red undertones which is great for me. Love the price. Works as well as the more expensive brands.

This serves its purpose! I use it to cover my thin spots or cowlicks! It works as good as any expensive products! I refill in an old topix bottle and shake onto needed areas ! The dark brown works for my rooted area with blonde frosts

I actually bought these because I was using a trimmer on my hair and inadvertently cut too much in one section, creating a bald spot. But I do have a balding crown, so I thought -- what the heck -- worth a try. The stuff actually does work. The directions tell you to use a fixative (I assume any hair spray will work) but on my first day's experiment, I just shook it on and did a bit of combing to even it out. It not only covered my bald spots but stayed in for the rest of the day. I wouldn't use it on a daily basis, but when I really cared about my appearance in public -- I think I'd use it. This one appeared to be one of the least expensive of the lot and that's the only reason I chose it over the others. They all seem way too expensive to use daily.

Great product

Better value than Topik

Stays in place forever, super easy to apply, and both cheaper and way better than Boldify.

Good for the price, speaking of quantity.But it does stain everything it touches. I have used other brands that do not stain
