Kate Middleton Hair Apparent

Like Jennifer Aniston and Farrah Fawcett, the long shimmering locks of Prince William's bride-to-be Kate Middleton have nearly reached cult status. When the couple's engagement was announced last year, sales of shine booster hair products skyrocketed.

Dubbed the "unofficial hair to the throne," the princess-to-be has opted against a stuffy up-do for the Royal Wedding tomorrow. Instead, Middleton's chosen to wear her sleek, chestnut-colored hair down for a more contemporary look, according to her London hairstylist Richard Ward. With the ceremony taking place at Westminster Abbey before an estimated audience of 2 billion viewers, we'll soon see what her famed flowing locks look like underneath a tiara and veil.

To achieve her high-gloss style, you need high-quality shampoos, conditioners and masques. Check out the following innovations from hair product pros.
