How concerned should one be about products applied to hair such as hair wax? Is there significatant absorption to blood from hair?

He's talking about phthalates and parabens, neither of which are used all that regularly in skincare, haircare, cosmetics these days, and when they are their allowed concentrations are strictly controlled in Europe and the UK at least to be way below the concentration that would cause endocrine disruption. Parabens and phthalates should be avoided anyways since they can cause irritation when used too frequently, and generally only cheap cosmetics that use unstable formulas rely on those kinds of preservatives..either that or alcohols
If he's claiming that emollients e.g butylene glycol and saponins e.g sodium laurel sulfate can cause endocrine disruption i have no idea where he's getting that info from since the only data supporting any endocrine disruption is from parabens and phthalates far exceeding the quantities that you would get in cheaper shampoo formulas. Considering that most all commercial saponins and emollients are byproducts of coconut like fatty alcohols as well would make even less sense why he thinks this to be true. Its safe to assume he's lumping all preservatives in with all the cleansing ingredients used in cosmetics
They are not strictly controlled in the US. Phthalates are common wherever the bottle says "long lasting fragrance". It is literally the reason it lasts long. They aren't listed as an ingredient because it's in the fragrance.He's talking about phthalates and parabens, neither of which are used all that regularly in skincare, haircare, cosmetics these days, and when they are their allowed concentrations are strictly controlled in Europe and the UK at least to be way below the concentration that would cause endocrine disruption.
