Maybe the one you have is defective. You should exchange it for another brush. I use mine almost every day and it's still in good condition.

I have not havd a problem with this brush you need to clean it properly. Dont pull on the bristles you should also use a brush cleaner or a gentle mild soap while cleaning all of the brushes

Take it back to the store and explain the problem. Sometimes a brush can just be made poorly- it's not the design of the brush but just that specific one. They'll probably replace it!

I bought my brush as an individual purchase (not a kit) and have not had any problems with it.

Take is back. Someone was having a stupid day, didnt put in enough glue. It happens. Now if the next one does the same, then you know it's the brush/line!!

Oh no! I have this exact same brush. It came in a set as well. I don't have any issues with hairs falling out. It might just be a defected one.

No the brush is not falling apart after using it for a few weeks.

I have purchased this brush in a set and individually and have not had issues with the bristles falling out.

I would definitely return it, it should not do that.

Perhaps the quality control of the kits is not as good as the individual brushes, if you got it at Sephora I say go back. They are awesome with returns and wanting to keep the customer happy. They will help!

I use it with Smashbox gel and creme liners, and it works really well.

I would have to steer you away from using this brush with smudge pots. Go for a brush with a pointed end rather than the angled. This eats up the product, less surface area would be better. Also the harder bristles spread out the product as well. I have had to go over each line twice

i have only used this with a smudge pot and it works great. i have a lot of control with it.

It worked great for me with powders, creams, pencils, and liquids. Good control, not too stiff.

I only use this with smudge pots. it works really well but after a while it does need to be replaced because the bristles spread out so it's harder to get a nice thin line. but it does work really well with smudge pots, especially after the pot has been used a few times.

I use this brush with Smashbox Gel Eyeliner. Make sure you wet the brush before using. (Otherwise you will end up taking out huge clumps. This also helps shape the brush.) Also, I wipe off excess liner after each stroke to prevent clumping on the brush. Wipe clean after each use and you should begood to go.

The bristles are pretty stiff and work really well with the gel eyeliner pots. I have tried two other brushes and this brush is amazing.

It's fine for gel liners. I use it with Make Up Forever's pots of waterproof liner. But you do have to wash it after almost every use, or the brush gets stiff and cakey.

Yes, this brush is stiff enough to use with gel/cream liners. I use it with my smashbox gel liner.

I use this brush with my Stila Smudge Pots and it's bristles are stiff enough (but not hard as a rock) so I get the perfect line lash everytime, I first dab the brush into a drop of water and then apply gel liner and I clean my brush everyday so it stays in great condition

I actually purchased this in store at the Rosedale Mall location in MN. Nylon bristles are stiffer, which will give you more control.

I think it depends on the brush. The variety is constantly changing, and they offer both. If you look under the description of the brush, it should say, but I don't believe you can search it.
Personally I've used both, and as long as you get a good quality brush either one is fine. I was surprised to find that my synthetic one is actually softer

I use the natural bristle brush to apply a powder brow corrector-I wouldn't recommend a nylon brush for something like that. It all depends on what you are using it for.

It's short. I'd say 5"

Its about 3.5 inches long

It has a pretty short handle. I would say maybe about 7 inches or so. It will fit in most makeup bags.

This brush is perfect for creme eye liner. It really picks up and applies the product well and it is rigid enough that it can provide a beautiful line especially with creme liner.

I've only used this for cream eyeliner actually, never used it for anything else. I think it works great! Easy to control, and depending on how you've layered the product, it's easy to determine if you want a thin line, or a thick line.

they are 1/4" wide, about 1/4" in length on the long end and very thin and fine.
