*As stated by SeneGence.

LashSense FiberExtend is SeneGence’s fibre mascara, and it’s all about length. SeneGence says you get length and volume in one to two coats, and that it resists humidity and water. If your natural lashes are short or sparse and regular mascara just makes them darker, a fibre formula is the next thing to try before false lashes.

When your lashes need more length, not just more black, fibres are the easy next step.

Fibre mascaras build length by adding to the tips of your lashes, so the look is more dramatic than an everyday mascara. That’s great for evenings and photos. It can be too much for a quick school-run face. It comes in one shade, and it’s tagged limited, so availability may change.

At $35 it’s priced like the VolumeIntense mascaras. If you want everyday volume with color options, VolumeIntense is the easier pick. If you want the full false-lash effect, the LashSense Lashes Bloom Box goes further. For most days, though, FiberExtend is the simpler and cheaper way to get there.

Best for

Short or sparse lashes that need length and drama without false lashes.

Skip it if

You want a natural everyday look. VolumeIntense Mascara is softer and comes in more shades.

Liner first, then a primer if you want even more length, then FiberExtend as your last eye step. At night, go gently: Fooops! Color Removing Wipes or the dual-phase remover will lift it without pulling at your lashes.

What’s in it, in plain words

  • Fibre formula: a mascara with fibres, which SeneGence says gives length and volume in one to two coats.
  • Resists humidity and water: SeneGence’s wear claims for the formula.
  • One shade: a single shade, so there’s nothing to choose between.

My tips

Tip 1

Comb through while it's still wet if you see clumps. Fibres are easiest to separate before they set.

Tip 2

Stop at two coats. More fibres don't always mean longer lashes; they can just mean heavier ones.

Tip 3

Keep a little on the lower lashes, or skip them, for an evening look that doesn't feel heavy.

FiberExtend Mascara FAQs

What is a fibre mascara?

A mascara with fibres in the formula that build length on your lashes. SeneGence says FiberExtend gives length and volume in one to two coats.

Is FiberExtend waterproof?

SeneGence says it resists humidity and water. It isn’t sold as a waterproof mascara; for that, look at VolumeIntense Waterproof.

FiberExtend or VolumeIntense: which is better?

FiberExtend is for length and a more dramatic look. VolumeIntense is the everyday option with five shades. Pick by how much drama you want.

Can I wear FiberExtend with a lash primer?

Yes. UnderSense Lash Primer is made to go under mascara, and SeneGence says it boosts volume and length. Let it settle before the fibre coat goes on.
