This product is absolute genius! It fills in my scalp with a completely natural look. Very easy to use and the most important thing... it gives me a huge boost of self confidence, especially as a woman. I would recommend this product to anyone in the market for a little help in the hair department. Fantastic buy!

This stuff is pretty cool. You shake it on (not spray) and the little fibers cling to your hair. You use it in places that are thin (sorry, doesn't work for totally bald spots), or you can use it to help cover greys. It's easy to use and the coverage is good. I use it between hair dyes at the salon. It's great to give a little boost of color or fill in spots when you're going out but don't have time for the salon first. Nice confidence builder!

I will own up to the fact that I have never used anything like this before and didn't really know what I was doing when I tried it but it was nothing like what I thought. All I managed to do was make a giant mess as the fibers went everywhere in my bathroom. What I did get on my hair looked super fake and like I added a very noticeable colored powder to my head. I had high hopes but they didn't quite pan out. I have extremely thin fine hair and have been looking for something to help with that but I will have to keep looking. They may work great for some and it could just be that I don't know how to use this properly. If you have experience with this type of product, give this a try! It might be just what you're looking for.

I use this all the time to give my hair a fuller and thicker look. Works great and people can't tell I've used a little something something for my hair.

It does strength the fossils of my hair and I lose less hair after applying it. 4 stars.

This is pretty amazing stuff! I’ve used it to cover my incoming grey roots in between salon visits. Covers & matches perfectly. I also use it to cover my tape in remy hair extensions in between salon visits. It also makes my thinning hair (front top) look thicker & definitely gives me volume. I lightly spray my hair with hair spray which locks it in. Washes out easily. I’ve tried other root cover ups but nothing that not only covers grey but makes my hair look fuller.

From a distance, it looks ok, but if someone gets up close, they can see that there's something on your scalp. It doesn’t adhere to your hair or scalp; it’s just a dust-like powder. On top of that, this dust tends to spread everywhere when you’re using it. The fibers will get on your clothes, counters, or anything else that's near you.

This won't work miracles, but it can help thicken hair temporarily. The "fibers" powder will wash out, of course necessarily, but it can also rub off if you use too much. There's a lot of trial and error to find how much is needed for your hair.It's already a little messy to apply, and the best way to apply it is a little messier, with some sort of hair oil or conditioner so that the powder will cling better. This is probably a must if your hair is very dry, otherwise the powder may not stick.
