There are a few people who are wondering if they can use a lash comb on their own lashes. We have to make sure that we do not use the wrong tools for the job. Using a lash comb on your own lashes could potentially damage your eyes. You should only use a lash comb in case you have an infection or irritation and need to remove excess debris from the area around your eye. No, you should never try to do this yourself, as it could cause harm to your eyes. It is best if you go see an eye doctor if you want help removing debris from around the eyes in order to prevent any infection or irritation from happening again.
