I went mobile last year after completing my level 2. I did a year placement in a salon, and did half my apprenticeship 13 years ago in a salon so I know the ups and downs of both college training and salon training.
The Mobile work is building up and I'm doing quite well 9 months on, but if I had the choice I would have gone to work in a salon first absolutely, there's no substitute for the experience you get from working in that environment, you get to see pretty much all range of clients and problems to solve etc that you just don't get out on your own.
I am 36 and unfortunately it's really hard to get into a salon when you're older, plus i have a young child not yet in school so i can't couldn't commit to an employer anyway at the moment. I did really well in my salon placement last year and the owner was going to give me a job, but because I was upfront with her and said I was going to be working for myself too she said she couldnt risk taking me on incase I stole her clients! (which i would not do,) i was going to work just saturdays and cover holidays but she made her excuses and it didnt come off in the end.
I do enjoy choosing my own hours, but I am always on here, especially with colouring as i feel i am so under confident when it comes to colouring a new clients hair and choosing colours etc, so i am forever asking advice.
You do what you feel is best for you, I was very nervous starting out at first, but my cutting (which is my favourite thing) has really come on and I no longer feel really nervous when cutting a new client's hair, I just had to get on with it and do it afraid as they say!
Hope everything works out for you X
