Derek had Afro style hair that he ironed flat and would dye black if he saw one grey hair, This went on for many years until one night in a hot basement listening to live music he started to sweat and the black dye started to run down his face. He wiped his face and saw the black sweat  and walked straight out, The next day he came to my house and asked me to shave his head bald, early 80s i think. After that he never went without shaving his head every day, That's why he always took so long in the bathroom in the mornings, R.I.P. my Brother
