Boo to shampoo

From Duncan Blake

Sir: Matthew Parris may want to put his hair affair behind him (Another voice, 23 September), but I would like to take the opportunity of confirming what he says, as I have also abstained (from shampoos) for a number of years now.

My son-in-law told me that models for shampoo advertisements are asked not to use shampoo for three months before the shoot, which rather ends any discussion on the matter.
