Schwarzkopf's new Oil Developer is a conditioning, caring peroxide that's optimised to work with new IGORA ROYAL but which can also be used with old-style IGORA if you still have some tubes to use up. It comes in 4 strengths: 3% (10 vol), 6% (20 vol), 9% (30 vol) and 12% (40 vol). Use them as follows: 3% for darker or pastel colouring and for covering 100% white hair; 6% for tone-on-tone colouring, white hair coverage and lightening 1-2 levels; 9% for lifting 2-3 levels (3-4 levels with the Special Blondes), colouring with -00 shades and white hair coverage with the Absolutes; 12% for lifting up to 5 levels and for colouring with the Fashion Lights. Comes in 1-litre bottles. 6% and 9% are also available in 60-ml bottles that are the perfect size for mixing with 1 tube of IGORA ROYAL - ideal for the mobile colourist.
