Be Gentle with Them
It can be tempting to be a bit rough with your lashes and brows, especially if you like to remove your makeup in the shower or with wipes. The key to keeping them healthy and full is being as gentle as you can because, at the end of the day, they are hair and can fall out with too much tension. Instead of tugging and pulling your lashes when trying to remove mascara, use an oil-based cold cream to first break down the formula before washing it away with your normal cleanser.
This also applies to your eyebrows if you like to use an eyebrow gel for that fuller look. Use warm water and gentle motions to break down the product and make sure to brush the hairs in the direction of their growth so that there is no pulling at the follicle leading to hair loss.
