Hi all, im a beauty geek but own a salon. My senior stylist went on a hair extension course today. I was going to be her first model as thought would be a good advert fir the salon. Going from ear length to shoulder length. But she was told my hair probably couldn't have extensions done. Can anyone advise why? My hair is naturally red thick & curly. Which of these 3, or all of the above is the factor??? Thank you loads for any help
