Most schools offer a range of vocational training courses in place of some GCSE options. This could be the answer you have been looking for if you do not enjoy academic subjects. However, the newer vocational courses are not offered in all schools, so you will need to check with your school when the options information is released.
If you do have Beauty as an option, you may well find that you have to go to the local college for your classes, as this is the most sensible option for most schools. The college will already have a training salon set up and have qualified teachers on hand to teach you what to do.
You will be working towards a BTEC or NVQ level qualification, and will learn the essentials of Beauty starting with the basics. You can expect to learn about things like skin care, why it is important to keep skin clean, how the professionals achieve top natural skin care looks, the latest in skin care technology and what the customer may want to know. You will need to learn all the techniques, and beauty spans a massive array of skills; from make-up to nail art you will need to have a full range of skills to work in a salon, and the course will aim to prepare you for this future career. Some colleges have public days where members of the public can get trainee treatments at lower rates, which is a good experience for you as a trainee.
