Good Hair Day, commonly known as ghd, is a manufacturer of hair care products based in Leeds, United Kingdom. ghd leads the market for hair straightening irons and is sold in over 50,000 salons worldwide. In 2001, three hairdressers from Yorkshire put a radical new hair styling product into the hands of women across the globe. With the respect and loyalty of an army of devoted stylists, ghd quickly developed a cult-like status nationwide. A monthly trip to the salon was no longer the only way to have a good hair day - this could be achieved every day.
