This means if you use 60ml of hair color, you will need 60ml of developer.
Important considerations:
* Developer Volume: The specific volume of developer you need (10 vol, 20 vol, 30 vol, 40 vol) depends on:
* The level of lift you want to achieve:
* 10 Volume (3%): For depositing color or toning. Very minimal lift.
* 20 Volume (6%): Standard developer for covering grey hair, going 1-2 levels lighter, or matching your existing hair color.
* 30 Volume (9%): For going 2-3 levels lighter. Use with caution.
* 40 Volume (12%): For going 3-4 levels lighter. Generally used by experienced colorists. Can cause significant damage if used incorrectly.
* Your current hair color and desired outcome: A darker starting point requires a higher volume developer for a significant change.
* The specific Schwarzkopf Igora Royal color you are using: Some colors might have slight variations in recommendations.
* The condition of your hair: Damaged hair is more susceptible to damage from higher volume developers.
Therefore, to give you the best advice, I need more information:
1. What is your current hair color level? (e.g., a level 5, level 6)
2. What is your desired hair color level? (e.g., you want to go to a level 8)
3. Are you trying to cover grey hair?
4. What is the condition of your hair? (Healthy, slightly damaged, very damaged)
Example:
Let's say you are currently a level 6 and want to achieve a level 7 (using Schwarzkopf Igora Royal 7.0). You have some grey hair to cover. In this case, you'd likely use:
* 60ml Schwarzkopf Igora Royal 7.0
* 60ml 20 Volume (6%) developer
Always read the instructions that come with the specific Schwarzkopf Igora Royal hair color you are using. The instructions are the best guide for mixing ratios and developer volume for that particular product.
Warning: Hair color can be tricky. If you are unsure about the process, it's best to consult a professional hairstylist to avoid unwanted results or damage to your hair.
