Hi there,
I agree with the other girls on this one, training is very important. You will need it for insurance and you dont want to go spraying peeople without insurance, just one person with a bad reaction to the solution or stained clothes or an ashma attack from the spray and you could be ruined financially. The training covers a lot more than just the technique and you can get trained for as little as £70.00. It is worth the outlay if only for peace of mind, plus you will make the money back very quickly. If you could save up to afford a machine and solution you should be able to save up for training.
I get upset when I speak to customers enquiring about a spray tan and get told that either they or someone they know had a bad spray tan, it makes it hard for the rest of us who have been trained and practised until we were good enough to charge. The sad truth of the matter is that a happy customer will tell a few friends and family how good you are, an unhappy customer will tell absolutely everyone how bad you are. So it really is better for you and your business in the long run to go about it the right way.
Okay then, I'll get off my little soap box now (lol)
If you are only tanning for personal use then just keep practising and tell your guinea pigs that you are only doing it for fun, you really shouldn't be charging for the service
Good Luck
Nikki
