Also, do you have a decent long haired head block to practice on? I have a good quality one that I use just for practicing hair ups on. If you’re wanting to get back into hairdressing, whether to get a job in a salon or work for yourself, you’re going to have to get up to speed on quite a few new techniques so investing in some head blocks and training should be a priority.
If you develop a flair for hair up styling, you could earn money during the summer prom and wedding season just specialising in this area. Once you get established, you could do additional training on advanced cutting and colouring techniques when time and money is available.
No one becomes a master hairdresser overnight. It takes hours of practice so you just need to be patient and keep plodding on. You will get there if you believe in yourself. Best of luck!
