It's so frustrating. I've tried so many times to achieve a vibrant colour on my daughters hair. But only with constant use of crazy colour or the like can I keep it looking bright. So I gave in and let my daughter buy the dreaded xxl. Now as a hairdresser this has killed me to admit but her hair looks fab. The colour is lasting. And it doesn't feel in too bad condition. Why oh why is it soooooo hard to do the same with professional products. Argggghhhhh !!!!!!!!
