What does "progressive hair coloring" mean?

I've always had my hair colored by salons but cannot really afford that now. I looked at store products like Nice %26amp; Easy, and one box said, "Do not use if you have had progressive hair color."

Someone else told me not to switch to home products if I've been going to a professional salon all this time.

What to do? I am brunette and usually get it colored dark auburn but can live with brunette again if I have to.

Progressive hair coloring is the act of repeatedly getting your hair dyed until you reach your desired hair color.

A home kit would probably say not to use it if you have been getting progressive hair coloring because it will interfere with what your stylist has been doing

Progressive hair coloring products contain lead acetate as the active ingredient. Lead acetate is approved as a color additive for coloring hair on the scalp at concentrations not exceeding 0.6% w/v, calculated as metallic lead (21 CFR 73.2396). Bismuth citrate, the other approved color additive (21 CFR 73.2110), is used to a much lesser extent. Progressive hair dyes change the color of hair gradually from light straw color to almost black by reacting with the sulfur of hair keratin as well as oxidizing on the hair surface.

Semi-permanent and temporary hair coloring products are solutions (on rare occasions dry powders) of various coal-tar, i.e. synthetic organic, dyes which deposit and adhere to the hair shaft to a greater or lesser extent. Temporary hair colors that must be reapplied after each shampooing. The vehicle may consist of water, organic solvents, gums, surfactants and conditioning agents. The coal-tar dyes are either listed and certified colors additives or dyes for which approval has not been sought. The dyes may not be non-permitted metallic salts or vegetable substances.

The active ingredient for progressive hair dye products is lead acetate. In the U.S, the current regulation governs that lead acetate can be used as color additive for hair coloring as long as the concentration is less than 0.6% w/v. The most noticeable difference between oxidation and progressive hair dyes is that progressive dyes are intended to give a more gradual change in hair color.

Semi-permanent and temporary products are either in the form of aerosal spray, solutions or dry poweders (or sometimes called fibers). The key ingredient is usually coal-tar carried by a vehicle that may consist of water, organic solvent, gums, surfactants, conditioning agents. In the US, the rules governing the quality of coal-tar dyes are confusing and there is no guarantee that the temporary or semi-permanent dye products you are using contain non-approved ingredients. Ethical manufacturers should always issue a caution statement in the packaging of their products advising consumers to do a small patch testing for skin sensitivity. Specifically, the US government suggests the following caution statement: "This product contains ingredients which may cause skin irritation on certain individuals and a preliminary test according to a accompanying directions should first be made. This product must not be used for dyeing the eyelashes or eyebrows, to do may cause blindness." The US government further indicates that the manufacturer will be subject to regulartory actions if the caution statement is not properly addressed and if their products are found to be harmful under customary use.

Hair dyes work more like paint by covering hair strands with chemical colors or by mixing with the melanin granules without altering them.

There are three basic categories : 1) permanent, 2) semi-permanent, 3) temporary. Temporary form can be washed out instantly. As of now, permanent hair dyes are the most popular. They can be sub-divided into 1) oxidation hair dyes and 2) progressive hair dyes.

Oxidatioin hair dye products consist of dye intermediates and a solution of hydrogen peroxide. An example of dye intermediates is p-phenylenediamine which form hair dyes on chemical reaction. 2-nitro-p-phenylenediamine is another type of dye intermediates. They are already dyes and are added to achieve the intended shades. The dye intermediates and the hydrogen peroxide solution, often called the developer, are mixed shortly before application to the hair. The applied mixture causes the hair to swell and the dye intermediates penetrate the hair shaft to some extent before they have fully reacted with each other and the hydrogen peroxide and formed the hair dye.

Progressive hair dyes for men are products that gradually build up to the desired color with repeated use. Make sure that you educate yourself on the process by reading the box carefully before trying it. There is also a lot of controversy surrounding the long-term effects caused by the lead acetate often found in these products. So again, inform yourself and make sure you don't use a product that might be hazardous to your health
