I would like to substitute 9 vol for 20 vol fit grey coverage
2.6 oz of developer.
Any brand cream developer can be used with a color as long as it is mixed according to the manufacturer's directions and it is the appropriate volume.
Manic Panic color is meant to be used straight from the container. It is not to be mixed with a developer.
Their are 2 parts to a hair color system. The toner, or "color" part, and the developer, or "peroxide" part. Developers come in 4 different strengths called VOLUMES. 10 volume being weakest . Solite Matrix Developer is a peroxide developer. There are several other brands of developers. Most companies make their own brand and encourage you to use it with their toner, but you can use different developers, as long as they are the correct volume for the toner. All are peroxide products in a liquid or a creme consistency. 10 volume lifts the cuticle of the hair and allows the deposit of a color products to grip the hair. Most glazes are meant to be mixed with a 10 volume developer, but the container should tell you what volume ( 10, 20 or 30 ) and the amt to use. If the hair color says mix to a 1:1 ratio, it means for each part toner, use and equal amt of the correct volume developer. 20 volume peroxide developers lighten the hair and lift the cuticle to deposit color, 30 volume is strong stuff, can burn your hair and scalp and should not be used at home. READ THE INSTRUCTIONS IN THE TONER BOX.
i have the loreal technique preference permanent haircolor "natural black #3" and i dont know how much of 20 volume creme to mix it with.
More than likely the Loreal color kits provide 20 Volume developers.
Equal parts of 10V. Developer + 20V. Developer= 15 Volume Developer
Equal parts of 30 volume + 40 volume developers= 35 Volume Developer.
Sunday School Subsitute Volume 1 - 2011 was released on: USA: 1 January 2011
Equal parts of 5 volume developer + 15 volume will yield approximately 10 volume.
Redken Camo Color Developer is 20 volume.
you can't mix developer with developer to make another developer
