Wet your hair thoroughly with warm water. Apply the shampoo to your scalp and massage gently with your fingertips. Work the shampoo through your hair from roots to ends, before rinsing well with warm water. Repeat the process for a deep cleanse.

Liz favours sulphate-free shampoos which are kinder on hair at every stage of life, but especially so in midlife when hair can become more dry.
