Are you looking to work in a salon or work on a self employed basis?
Are you wanting training in different types of enhancements such as sculptured acrylics, gel etc.?
If you want to be able to apply for salon jobs, ideally, you’ll need to complete your Level 2 Nail Tech (and possibly Level 3) or several shorter courses run by reputable training companies such as those affiliated to one of the main professional brands such as Young Nails, CND, OPI etc. However, many salons won’t give you the time of day if you don’t have your Level 2.
Start by googling level 2 nail courses and your local area. You should find one or two colleges that offer suitable courses.
You will also see lots of independent training companies offering short courses but beware that many of them are a total waste of money and you’ll end up spending more money and time getting properly retrained. If you’re serious about this being your career, invest in yourself by thoroughly researching your training options and don’t scrimp on training. Be wary of online reviews as some of them are fake.
Despite what the adverts might tell you, you cannot become a competent nail tech through online training. It’s something where you need hands on support from a good tutor.
Lots to think about and feel free to pop back and ask more questions.
