Mix Schwarzkopf Igora Royal Color Tube 3-0 Dark Brown with Igora Royal Oxide Developer at a 1:1 ratio — for example 60ml of colour to 60ml of developer — stir until smooth, then process for about 20-35 minutes. The ratio never changes across the Igora Royal range; what changes is the developer strength you pick, because 3%, 6%, 9% and 12% decide how much lift you get.
What is Schwarzkopf Igora Royal Color Tube 3-0 Dark Brown?
It is a tube colour from the Schwarzkopf Igora Royal range and it only works when mixed with Igora Royal Oxide Developer. The colour deposits the tone while the developer drives development and lift, so the same 3-0 Dark Brown tube gives a different depth depending on the developer volume you choose.
What do you need to prepare?
- Schwarzkopf Igora Royal Hair Color (tube)
- Igora Royal Oxide Developer (suitable volume)
- Mixing bowl and application brush
- Gloves, hair clips and a towel
- Timer, water and a post-colour conditioner
Which developer strength should you choose?
- 3% (10 vol): deposits colour only, no lift. Suitable for covering grey hair or refreshing an existing colour.
- 6% (20 vol): lifts 1-2 levels. Suitable for a light lift with full coverage.
- 9% (30 vol): lifts 2-3 levels. For a medium lift and brighter tones.
- 12% (40 vol): maximum lift (3-4 levels). Used for noticeable lightening.
What is the mixing ratio?
It is 1:1 — equal parts Igora Royal colour and developer, for example 60ml colour + 60ml developer. Guessing the ratio throws off both the tone and the coverage, so measure it properly.
How do you mix it step by step?
- Squeeze the amount of colour you need into the bowl.
- Add the same amount of developer.
- Stir until fully blended with no lumps.
Application tips for even results
- Strand test: test on a strand of hair 48 hours before the full application.
- Section the hair: divide it into small sections so the coverage stays even.
- Apply at the roots first: for regrowth, process the roots first before the ends.
- Processing time: usually 20-35 minutes (refer to the instructions for exact timing based on developer volume and the result you want).
What should you do after application?
- Rinse the hair with warm water.
- Use SLS-free shampoo and conditioner, ideally a Schwarzkopf post-colour care range.
Important points to remember
- Avoid mixing too much: prepare only what can be used within 30-45 minutes to prevent oxidation.
- Wear gloves: protect your hands throughout the application.
- Consult a professional: if you are unsure about the developer choice or the technique.
Safety warnings
- Do a patch test to detect allergies.
- Avoid contact with the eyes; if it happens, rinse immediately.
