You use 20 volume to cover grey hair.
20 Volume Peroxide (or developer) is required for coloring white hair. It lifts & deposits in one step.
At least a 20 Volume, 6% peroxide should be used for lifting. Although, the hair tone can still be changed with 10 Volume, 3%. Using this however, you will not see much lift.
No, the higher the developer number, the more drastic of a color change it will provide when mixed with dye. 20 volume is generally used to change the hair about two shades, if you would like it more dark or light, use a 30 or 40 to get about 4 shades away from the gray.
Usually 30 volume peroxide is mixed with lightener for blonding purposes. Or for lifting 3 levels with color.
Yes, 6% or 20 Volume peroxide is ideal for mixing with red hair color.
It's not necessary to purchase developer (peroxide) from a hair salon. A regular beauty supply store carries it as well.
30 volume developer, or peroxide, will successfully lift naturally dark brown hair, resulting in nice highlights.
Grey eyes with blond hair should work.
Yes and no ; some times. =) It depends on what peroxide you're using. If you're using the peroxide you get in the brown bottle at wal-mart for 50 cents then no. But if you're talking about the peroxide that lightens your hair - yes. If you're going to get rid of head lice using the peroxide route try a 20 volume peroxide. This will lighten your hair 1-2 shades (with no bleaching powder!) and kill all lice and nits. You could use a 30 volume if you wanted lighter hair or if you were crazy about getting the lice out, however Do not EVER EVER EVER put 40 volume peroxide directly on your scalp. It will burn your hair off.
No probably not.
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.
If the target color is only one level lighter, use 20 volume. If it's more than one level, use 30 volume. 40 volume is generally not recommended and should only be used by experienced professional hair colorists.
