Additionally, people with little or no training are doing jobs that leave much to be desired and will require a correction made by an expert.
Right now there are many cases for corrections and many more are coming. That's a great opportunity for business and get more clients but you have to be prepared. Do you know how to correct old Permanent Makeup or Microblading?
My recommendation is: get ready, study, practice and do not try to do something that you don't know. Get trained by an expert in corrections.
