Looking for advice on gel course

[Sim123]

Hello, I've done lots of reading of previous threads but I still can't decide which gel polish course to do - looking at localish courses I have Shellac / IKON.iQ Prima Gel both of which include a kit, or Halo which doesn't. Grateful for any suggestions please/

Between those 3 I would go with Shellac or Ikon as they both use hypoallergenic and HEMA free products. Better long term for yourself and your clients.
Shellac has been going a long time, Ikon is relatively new but very hot on anti-allergies!

thanks, the only drawback with the Shellac course is finding someone free to 'model'
