Hair - - Need To Know -

So, what re­ally is this sub­sti­tute in­gre­di­ent? Well, it is an in­gre­di­ent called MEA. Ev­ery per­ma­nent hair colour needs an ac­tive in­gre­di­ent, called ‘al­ka­lizer’, so that the hair colour can en­ter the hair cu­ti­cles and colour it. Ammonia is an al­ka­lizer that has been safely used in hair colour­ing for 50 years. no ammonia colour uses MEA to re­place ammonia as the al­ka­lizer. MEA is not a new tech­nol­ogy, as it has been used in demi/ semi per­ma­nent hair colours in a safe way. MEA re­places ammonia in per­ma­nent hair colour, but it is re­quired to be in higher con­cen­tra­tion to work ef­fec­tively as an al­ka­lizer. And that’s when it be­comes more dam­ag­ing for the hair. Maria Cas­tan, Sci­en­tific Com­mu­ni­ca­tion Ex­pert, Wella Pro­fes­sion­als, said, “Lat­est per­ma­nent colour prod­ucts claim­ing no or low ammonia typ­i­cally re­places ammonia with an­other al­ka­lizer — MEA. Nei­ther MEA not ammonia on their own are good or bad — it largely de­pends on the con­cen­tra­tion of al­ka­lizer (ammonia or MEA). We have also not seen any ad­van­tage of ammonia-free per­ma­nent colour prod­ucts in terms of hair pro­tec­tion. This is ev­i­denced by both in­ter­nal and ex­ter­nal test data we con­ducted, as part of our reg­u­lar in­no­va­tion bench­mark­ing process.”
