Yes, most states (in the US) require that you have some type of a health or beauty license to apply eyelash extensions in a professional environment. This can include an esthetician or cosmetologist license, makeup artist and nursing license to name a few. We also recommend that you check with the State Board of Cosmetology in your state or whoever regulates beauty services if outside the USA to see if a specific license is required to apply eyelash extensions. We have compiled a list of US state requirements, please see here. Prior to taking the online training please scan and email a copy of your license to contact@lashoutpro.com.
