Thanks for checking in. Not only is NULASTIN safe to use with eyelash extensions, we highly recommend you make it part of your eyelash care routine.

Extensions are very damaging to your natural lashes. NULASTIN is designed to nurture the cells that produce hair follicles and will be your best defense during extension use.

We recently had a customer write the following review after using the lash serum for 3 1/2 weeks:

"I could not really tell if anything was happening, as I am a diehard eyelash extension junkie... which of course damages my real lashes a lot, thin spars and weak. I just had my lash lady do a set and she gives NULASTIN two thumbs up. She was very impressed with the difference using for just three weeks made and told me USE IT ALWAYS. It is a must-have for people who get extensions, to counteract the damage. Also it does not make extensions fall off or dissolve the glue."
