My hairdressing career spans 66 years (45 years Hands On behind the chair). I am still current and still learning today and hope to do so as long as possible into the future. Being practical I understand a lot of what I learnt no longer applies, because we are in a fashion business and things move on very fast. I have condensed what is and always will be relevant into this book. It is not a photo book of hair colours that I have done over the years. It is a technical explanation of how humans see hair colour.
