This is one of the most popular questions I get asked as an artist and different people have many opinions on this! The answer is both YES and NO! If you are putting extensions that are too heavy for your natural lash, then yes, after time your lash will become stressed out and begin to grow in thinner and possibly shorter. If lash extensions are too heavy or stuck to other lashes and they are pulling, again this will disrupt your natural lash growth! Think of it as waxing or tweezing, if a hair is constantly being pulled out before it’s life cycle, it will begin to grow in thinner and thinner and then possibly not at all! However, if your lashes are being put on responsibly and they are not too heavy or stuck to multiple natural lashes, they do NOT harm your natural lashes! I have clients who have had lashes for years and have no damage, no breakage! This is because the weight and the length of the extension is properly measured to ensure their natural lashes will not be harmed in the process! Clients also understand and follow correct after care instructions to ensure their lashes stay clean and their lashes don’t get weighed down in old make up or dead skin (yuck!) So in short, when properly applied, you can have lashes for literally years and have no problems! When you are looking for a lash artist don’t be afraid to ask as many questions as possible! You should feel 100% confident your artist knows what they’re doing and they care about your lashes health! If you feel like they aren’t listening to you or lashes feel heavy and like they are pulling, definitely let your artist know right away and if they seem unconcerned, it may be time to start looking elsewhere. I hope this cleared up some questions regarding extensions and they’re harmfulness! Now go out and get some lashes!
