This happened to me for the first time recently when one of my mascaras is drying out. I really like the shape of the spoolie, so I washed it and tried it in another tube of mascara. The result was slightly different from either of the original mascaras – I’m still experimenting with this as I’m always looking for the mascara / wand that works great on my lashes. Have you ever tried mixing and matching tubes and chopsticks? What do you think makes the biggest difference – the mascara itself or the applicator?
