“Instant Volume Boost for Thinning Hair”
Mariela hernandez—July 31, 2025✓ Verified purchase
Thick Fiber is a game-changer for anyone dealing with thinning hair. The application is quick and easy, and the results are instantly visible — it really makes your hair look fuller and thicker. I love that it’s wind and sweat resistant, so it stays in place throughout the day. It doesn’t cause any itching and blends naturally with my hair color. Perfect for everyday use or special occasions when you want to feel more confident. Highly recommended! Read more

Undetectable
MB—April 17, 2025✓ Verified purchase
Very happy with the results. It does take some practice. My wife looks at me very close and she says she cant tell its not my hair. I would recommend the bulb applicator that goes on top of the bottle to apply to the front of my hair line. I use the shaker that it comes with it to apply to the back of my head. Need hair spray to keep it from coming out in the rain or wind. I've left it in for 3 days with just touch ups after waking up. Will rub off if going to bed with it. I use a towel around my white pillow. I some times wear a hat with the fibers in and the had no effect it as long as I don't rub the top of the hat into my sculp. It will come out in the shower, Not easily. I have to shampoo at least twice. I have very dark hair... in most places .. lol Read more

No more bald spots
Caroldell—September 14, 2025✓ Verified purchase
This stuff is amazing!!! I have really think hair and a lot of it. But I’m 63 and when I would put my hair up on both sides of my head in front I’d have a bald spot on each side. This stuff is very easy to use with no mess at all. No more bald spots!! Read more

Doesnt work. Looks blotchy and clumpy

It clumps up and when touched gets wiped. I dont think this is as good as xfusion or toppik. It performs slightly better than boldify though. Read more

Use it if TOPPIK is too much for your budget
WebGo—July 2, 2025✓ Verified purchase
This is NOT a bad product. I tried it because what I normally use is TOPPIK. But this seemed to cost less, so I gave it a try. It doesn't cover as well as TOPPIK and it seems to clump up a bit, so you have to sprinkle it on very, very lightly and then comb it through each time to avoid clumping spots on your scalp that people will see a dark spot through your hair on your scalp. TOPPIK covers better and by using less and doesn't cause that clumping patch if you're not careful. I would say use it if TOPPIK is too much for your budget, otherwise, spend a little more and get a better product by getting TOPPIK. Read more
