Sassoon was too young to fight in the Second World War, but in his teenage years he joined the "43 Group", a collection of Jewish ex-servicemen and youths who engaged in anti-BUF vigilantism following VE Day. He later fought in the IDF during the 1948 war.I thought Vidal Sassoon made hair care products.
