After some advice please. I’ve just completed my gel nail course and now looking into what kind of extension service to offer that’s not acrylic. Should I learn hard gel and biab and polygel? Is there a need to be able to offer all? Also should I learn tips/forms and dual forms? Is one better for people wanting long nails and one better for people who want shorter nail extensions?What do people ask for the most in your opinions? I’m so confused between them all- any advice would be great thank you xx
