A Very Natural Looking Quick Fix!
Works exactly as promised! Application takes some practice, as you need to learn to apply it as gradually as possible so as to avoid clumping or over coverage or spilling. I strongly recommend ordering the squeeze bulb applicator (plenty available on Amazon). This will help you apply it very sparingly at a time to achieve a much more natural look. For extra confidence, use a bit of hair spray after. You can move your fingers through your hair or even lightly comb/brush it without the product coming off. Mine didn't even come off on the pillow and was still in place the next morning until I washed it out in the shower.

WORKS VERY WELL
I normally do not write reviews but I have to do it because this product made me very happy. I have hair loss at the top of my head. This has always made me not confident hungry out with my hair without covering my hear. BUT NOWWWWW I am ready to go out everywhere with my hair uncovered. Yayyyyy I used it as soon as I got it. Then sprayed GOT TO BE GLUED FREEZE SPRAY. The hair fibers stayed intact. I will be buying it again and again.

100% awesome.
Works great. No itching, fills in great for guys with thinning hair. Does not fall off with rain or sweat. Product is a 100% as described. Just my humble opinion on this and what I experience with this product.

Undetectable
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

Accelerated hair loss! Not natural; contains formaldehyde-releasing preservative
This product is marketed as all natural. After a week of using it, I noticed a substantial increase in my thinning hair spots that have been consistent for almost 15 years. My photo shows a spot that has almost completely cleared out of hair when it was just a thinning area a week ago. To be fair, it provides excellent coverage and completely masked any thinning spots, leaving me with a very dark head of hair, where not even parts of my scalp were visible When I looked up the ingredients that are on the container, not listed on this product page, I found that one of them can actually cause hair loss. I’m furious about the false advertising in this description claiming all natural ingredients, and at myself for not looking up the ingredients when I received the product. For reference it contains keratin, Cetrimonium, chloride, silica, and DMDH hydantoin (a formaldehyde releasing preservative).

Use it if TOPPIK is too much for your budget
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.

I usually never comment after purchasing a product on amazon and I've bought a lot on this website, but I just had to after experiencing this masterpiece. It actually works EXACTLY how you expect it to, It saved my hairline and blends in perfecty with black hair. You must pair it up with a spray though, it only costs around 5 bucks. Also getting a blast freeze spray for another 5 bucks will server you even more justice as it will lock the hair fibers into place and get you an extra layer of protection to ensure it never falls out through out the day. Overall amazing products and amazing results. Worth every penny for those who're unsure and there's no way you will ever regret it.
