Lunar Tides | Siam Orange Hair Dye Siam Orange is a one of a kind vibrant orange hair dye! Please do a strand test before doing an all over application. Attention first time bleachers: if you have dark hair or previously dyed hair and are planning to bleach your hair prior to dye application, know that you must lift to a pale yellow to platinum colour that is evenly bleached. The colour of the hair prior to applying the dye will impact the shade results. All colours look best on platinum but darker tones with work on light and pale yellow tones of hair.
