Good quality cosmetics
I don’t think this is hair fiber - it’s more like a cosmetics powder, similar to eyeshadow. You apply it with a sponge, and it effectively fills in thinning areas. Hair powder has been a game-changer for me. If you have balding hair, I highly recommend giving it a try! I’ve tested different brands - this one is good. It’s not the best, but it’s cheap.

Great product
Covers the roots very easily. Only problem is it can stain pillows and hands if it comes in touch.

Doesn’t cover grey roots
Bought it as I don’t like the root sprays, but it doesn’t actually cover grey hair - it dulls it, but doesn’t cover it. Not worth the purchase

Wow, I'm so impressed
I tried so many root cover items from many brands and different price ranges but this is wow i'm so impressed. 1- So easy to cover immediately, 2- great application that press the product in place. 3-The brush is so high quality and tangle flat that i decided to use it for face contouring and i'm using their round applicator for the roots but I use for hair line an eyeshadow small brush. 4- Colors are ture. i have mediium brown but ordered dark brown to cover the white but its a little dark I decided to re-order medium brown and mix them together Highly recommended

This product works well for thinning hair. Husband has been using it for years to infill his sparse frock... thickens, darkens and stays... for the most part. Deep Sea diving likely won't hold up but definitely stays all day without falling and creates a luscious hairline for photos. 100% confidence booster. Mother in law loves it too for when her hair is up in a ponytail.

Mon mari trouve le format très pratique et facile à appliquer. Seul bémol c’est qu’au réveil il y a eut un transfert sur l’oreiller.

円安と言うこともあるし、直販では無い売主だからマージンを取られていると言うこともあるけど、内容量と値段のバランスを考えると「どうしてもこれじゃないと駄目」と言うほどのものではない。 Instagramで見て興味を持って購入してみたが、見た目は確かに良いけれど、外箱、付属のブラシや本体ケースはこんなに仰々しくなくても良いのでは?変なところにコストが掛かって値段が上がってない?と感じる。 また、パウダーなので、つけたときに髪がマットな質感になるというか…というか粉浮きしたような見た目になる。 軽く水をスプレーするとか整髪料などをつけると髪に馴染んで綺麗にはなるけれど。 ブラシについては、正直髪に対しては色づきがそんなに良くないと感じた。地肌につけたい場合は良いのかも。 髪だけに色をのせたい場合は、パフではたいた方が個人的には色ノリも良いように感じる。 日本人は毎日シャワーを浴びるので、これをつけたまま寝ることはなく、色が枕移りするかどうかまではわからないが、普通に過ごしている中で色が落ちてきて困ると言うことは基本的にはないです。

Great touches up your roots and hides grey hairs showing at the temple that sometimes the hair colour doesn't take. Makes my hair look thicker. I was recommended to try some by my hairdresser but any make.
