Good hair day (also known as 'GHD') is an English hair styling company, and the UK's leading manufacturer of hair irons and hair products, . Owned by Jemella Group, the company was founded in 2001 by Martin Penny, Gary Douglas and Robert Powls.. In 2007, after being sold to Lloyds Development Capital just 11 months earlier, Jemella was re-sold to management backed by Montagu Private Equity group for ₤160 million.
GHD's hair irons are made by a South Korean company, KICA, that has so far produced a very successful range of hair products. The company's notability comes from its "iconic" line of hair irons, which have been described as "one of the most successful hair products in history" by the Yorkshire Post. Their popularity, becoming a "fashion 'must-have'", derives from their celebrity fans, such as Madonna, Gwyneth Paltrow, and Victoria Beckham. As a result, Martin Penny won the The North Region Consumer Products Entrepreneur of the Year in 2005 for the product, and Consumer Products Entrepreneur of the Year. The product has been involved with many fashion shows, such as New York Fashion Week, Alice McCall, and Willow Lingerie, and also sponsored the 2004 season of reality TV program The Salon.
The irons come in three sizes, GHD IV Styler, GHD IV Salon Styler, and GHD IV Mini Styler. The 'GHD Styler' is the average size, while the 'GHD Salon Styler' uses larger heating plates, and the 'GHD Mini Styler' makes use of smaller plates. In 2008, GHD launched 2 limited edition 'Dark or Pure Stylers' in glossy black or white.
The irons use ceramic technology on their heating plates, which is the reason for the golden, rather than silver, appearance of the plates. The technology involves using ceramic on the blades rather than traditional metal which reduces the frizzing and damaging impacts on the hair caused by the severe heat. Regardless, GHD does offer several hair care treatments as well as a variety of other such products to counteract the heating effects of their straighteners..
In February 2007, a rash of thefts targeted GHD hair straighteners at hair salons in the UK.
In June 2008, GHD released a limited edition 'dark or pure' series. The styler is a mk4 styler; however, it is glossy rather than matte. The pure styler is entirely white, while the dark styler is entirely black. This range was limited to a release of 10 dark and 10 pure stylers per salon.
