The reaction occurs under moderately alkaline conditions, specifically when the pH is ≥ 8. [22] This reaction is quite prevalent in household environments due to the pH range of household wastewater being 6–9 [26] and the prevalent existence of parabens in cosmetic products. When paraben-containing cosmetic products are discharged into ...
adjusting pH to that of non-stress tears, approximately 7, which may be a higher pH than that of shampoos which are pH adjusted for skin or hair effects, and lower than that of shampoo made of soap; Use of surfactants which, alone or in combination, are less irritating than those used in other shampoos (e.g. Sodium lauroamphoacetate)

Just when you thought the list of COVID-19 symptoms couldn't get any longer, studies show hair loss and thinning hair should be added to the ever-growing list. One study followed 806 participants ...
When adult armpits are washed with alkaline pH soap, the skin loses its protective acid mantle (pH 4.5–6), raising the skin pH and disrupting the skin barrier. [7] Many bacteria are adapted to the slightly alkaline environment within the human body, so they can thrive within this elevated pH environment. [8]
Ketoconazole Side Effects. Side effects from ketoconazole are rare. In the 2019 study we mentioned earlier comparing ketoconazole shampoo to minoxidil, only 10 percent of people reported side ...
A solution containing ammonium thioglycolate contains a lot of free ammonia, which swells hair, rendering it permeable.The thioglycolic acid in the perm solution reduces the disulfide cystine bonds in the cortex of the hair. [2]
