I am requesting a full refund for the £280 hair service I received. I provided clear reference photos of the colour and cut I wanted, but the final result is significantly different. The colour is not blended as requested, the haircut does not match the style shown, and my previously natural, healthy hair now appears damaged. I am very disappointed with the outcome and do not feel the service was carried out to a professional standard. Please advise how my refund will be processed.
