*1* A chemist’s choice of shades is limited and their colouring advice is inadequate.
*2* It’s difficult to apply hair tint to the back of your own head, resulting in patchy colour.
*3* You may not have good quality after care conditioners at home.
*4* You may ruin your towels !
*5* The grouting around your bathroom tiles will never be the same colour again !
Trust your local hair care professional.
