1. Seasonal Changes - The changing of the seasons causes us to shed our lashes to grow our new coats for the season - yes this happens for humans, too! This is totally normal, you might just need to suggest that your clients get a fill sooner than usual while their lashes are shedding.
2. Makeup/skin care - it is essential that you remind your clients that clean lashes are healthy lashes! If they regularly wear makeup it is necessary that they wash their lashes everyday with LashWash. This will ensure that their lash line is clean and free of debris and also that their oil glands in the lash line will not become clogged which can result in a reaction. A clean lash line is a happy lash line.
3. Masks - this is a bit of a hot topic right now, but if your client wears a mask all day this could contribute to poor retention due to the humidity and warm breath coming up and causing the adhesive to weaken quicker. Tape down your clients mask and implement a no talking policy.
