Thanks for your replies guys.
I have taken root for me's advice and am waiting for a system to arrive after going to see Jo in Swindon. I am so excited because she went through everything with me so I have 100% confidence that it is going to be a huge improvement on my current one. Not only this but it is going to be a fraction of the price of the poor quality system I got from advanced hair studios.
I wish I had found Jo b4 I went to advanced. Would have saved me a lot of stress and a lot of money!
