Now I was mentioning to this person how salicylic acid is just ONE acid property used in Hair Razor Detox and how others product makers dont have a clue what they are doing . I mentioned Toxin wash as an example but any detox shampoo is the same.
My point was that Toxin wash instructs you to use dish soap and TGEL prior to using toxin wash ,... WHY ? why are the properties of TGEL or dawn dish soap for that matter not in the toxin wash ?
BECAUSE THEY DONT FORMULATE their own product its just shampoo .
Furthermore TGEL is worthless and they should at least suggest TSAL , showing not only do they not formulate anything they dont even understand the science of the chemicals .
Neutragena TSAL is far less effective than home method touters think
After making this point i went on to explain how even the "mac method" home remedy type detox suggest salicylic acid and being they can only get it over the counter at 2-3% they generally use neutragena TSAL %3 being the (supposed ) strongest product .
You see salicylic acid is a beta hydroxy acid and like similar acids the PH determines the FAV or Free available value .
Salicylic acid has a ph of 2.8 and begins to loose it potency at ph of 3 and is useless by ph 4 .
Now, if you multiply the percentage of free acid by the concentration of Salicylic acid present in the bottle, you can work out how much is ready to pass through your hair.
Neutragena TSAL %3 at ph of 3.5 leaves only % 0.68 Free available acid so its more like % 0.5 solution .
Hair Razor using just the salicylic acid as one example ( other properties we wont mention actually do more) has a % 4 value at ph 2.5 ( %90 available of the % 4 solution) and
Layering Products and Wait Times
pH affects the acid you use and how it works. Another consideration is not to disturb an acid while it is on your skin, which can alter pH and affect its action.
Generally speaking an acid is effective for approximately 20 minutes . After that point the hair pH has risen enough to lessen the action , and the acid is effectively neutralized. During this time frame, the acid is working at effective levels. so we suggest a 15 minute time frame for our applications as it has done its job by this point .
