There are a lot of therapists on here who will tell you that a one day training course is fine. I have done many short courses, but all on the back of an NVQ that I did years ago. Personally, I think short courses have their place, but I think that an NVQ gives you a good grounding in beauty. As with all courses, some training is better than others, but generally speaking, an NVQ will set you up ready to perform the most popular beauty treatments.
No course on it's own is enough. You have to be prepared to practice in your own time. Many will do the training at college, and never touch a wax pot outside college hours. Needless to say, they're not going to leave college as proficient waxers.
If you look at many of the posts on here, one of the most common questions is how to get more clients. Competition is fierce, and many are throwing themselves into the work place with no real understanding of how they are going to run a business. Why should a client start coming to you - to just set up and say "I'm here" isn't enough. The more treatments you offer, the more likely you are to attract more diverse clients, and many will cross over, from waxing to nails etc.
Finally, as an employer, you could have every day course under your belt, but if you don't have NVQ2 and 3, I wouldn't be interested in employing. You may want to go it alone, and set up on your own, but what if that just doesn't work? Do you want to be employable? Also, many local authorities are now insisting on NVQ 2 as a minimum for those wanting to set up a salon at home or in premises.
If this is your future career, do you just want to do a few day courses, or do you want to learn everything you can and come out with a recognised qualification?
You can see where my advice lies. Do an NVQ and come out trained in all aspects of beauty. Be insurable and employable and ready to work, or do some day courses, it's up to you.
