Answer: The first known electrically illuminated Christmas tree was the creation of Thomas Edison's associate and partner, Edward H. Johnson. In 1882, while Johnson was Vice-President of the Edison Electric Light Company, he had Christmas tree bulbs made especially for him. He then hand-wired 80 red, white and blue light bulbs and wound them around his Christmas tree which he displayed at his home in New York City. In 1903, General Electric began to offer preassembled kits of stringed Christmas lights. Edward H. Johnson became affectionately known as the Father of Electric Christmas Tree Lights.

Pityriasis capitis is commonly known as dandruff. Dandruff is a common skin condition that causes the skin on the scalp to flake and itch. Dandruff affects about half of all adults, with males more often affected than females. It typically begins throughout adolescence and becomes less prevalent after the age of 50. A gentle daily wash can be used to help treat mild dandruff. Head & Shoulders is the number one anti-dandruff shampoo brand around the world. With sales reaching over $100 billion each year, it is the leading shampoo in 180 countries.
