Grey Hair CoverageUpdated 3 months ago

In order to achieve maximum grey hair coverage a base shade may be required. The table below gives recommendations of the quantity of “base” needed for optimum results.  
The Activator recommended for grey hair coverage is 6% (20Vol). 

For highly resistant grey hair we DO NOT recommend decreasing the amount of Activator. Instead we suggest using a base shade ½ to 1 level darker than desired result.  

For example: 

Desired shade: 6.13 

Grey: 75% 

Mixture: ½ 5.0 + ½ 6.13 with 6% (20Vol) 

Development Time: 40–45 minutes
