Colour, cut, light.

A small sunlit hair salon: a woman with long dark hair, seen from behind, sits in a leather chair before a tall arched mirror; the name Tresswell is painted on the wall above it

A hand stirs pale lightening cream in a white bowl with a black tint brush, on an oak trolley beside the chair

Seen from behind: the brush paints pale cream down one dark strand that lies on a sheet of foil; folded foils hang on both sides

The hand presses the foil closed over the painted strand: one more silver packet among the others

Seen from above a black basin: a hand moves a shower over long hair; the cream runs off in milky water and the ends come out the colour of caramel

Close on wet hair against the cape: two fingers hold a section level and steel scissors take off its tips

At the window: a round brush and a black dryer draw one section of honey-gold hair down to its ends

Seen from behind against a sunlit wall: a hand lifts the lengths of her hair, dark at the roots and honey at the ends
