I bought this as a birthday present for my mum, however I was extremely disappointed to learn that although the deal said FULL HEAD PERMANENT COLOUR the stylist only COLOURED THE FRONT OF MY MUM's HEAD hence only her grey hairs were treated. I wish I would have accompanied my mum as she only told me this once she arrived home. Now to my knowledge and past experience in other salons upon purchasing deals from treatwell FULL head colour means THE WHOLE HEAD. I was so disappointed with this deal as primarily My mum wanted her hair coloured.
