When his designs began to be featured in Vogue, people realised that the possibilities for colour were endless. After the success of crazy colour, Daniel took on another challenge, reinventing hair colour so that this time it would look completely natural. He reintroduced henna, mixing it with other natural ingredients such as black coffee, lemon juice, the yolk of an egg and even hot red wine. Through working with semi-permanent colour in new ways, he developed numerous colouring techniques, such as Tortoiseshell Lights using three tones of highlights.

Daniel began to pay close attention to the way that eye colour and skin tone work with the hair's pigment. 'When you have the perfect hair colour,

the first thing people should notice is your eyes, never your colour' - this fact, he maintains, is testament to the skill of the naturally gifted hair colourist.

During the early 1970s, Daniel started working on films, including such classics of the era as Clockwork Orange, Barry Lyndon and Murder on the Orient Express. In 1977, he left Leonard to open his first salon on George Street in Marylebone, the same street where he can be found to this day. This was Europe's first specialist colour salon and it was here that Daniel began training a new generation of specialist colourists, many of whom have gone on to become some of the biggest names within the industry.

In the 1980s, Daniel achieved another milestone, becoming the first colourist with a signature line of professional hair colourants and hair care products design to create and nurture natural, iridescent colours 'more beautiful than nature intended'. Then, in 1990, he was invited to endorse a range of professional colour products in Japan for Hoyu Co Ltd. He has since become known as the man who introduced the concept of professional hair colour to Japan and the Far East, where some 63 million people now colour their hair. Throughout the 1990s, Daniel continued to push the boundaries of hair colour, inventing new techniques and always striving to achieve stunningly natural hair full of movement and shimmering colour, unlike anything seen before.
