After the first episode of of
Are You Being Served? (1972), she decided her hair was too plain for the outrageous personality of Mrs. Slocombe, so she bleached it white, then dying it a different colour for each subsequent episode in the first season. Unfortunately, the ends of bleached hair become "spongy," causing the dyes never to entirely wash out. Her twin 10 year old boys didn't appreciate being picked up from school "by a mother with multi-coloured ends." So, after the first season, when she saw the show was a hit, she asked the BBC to supply her with wigs instead of dying her hair a different colour every week.
