According to Cucinello, there may be a big difference between some drugstore and designer shampoos, after all. "There is a reason why some products are more expensive than others — the quality of the ingredients,” he notes. “Cheaper products tend to have larger molecules of waxes and oils that can build up on the scalp, clogging the hair follicle and causing excessive hair shedding."
What you can do: Cucinello says to look for ingredients that are refined or considered non-comedogenic (he’s personally a big fan of Briogeo products). “Some of the more inexpensive drug store products are now starting to boast that they contain natural ingredients like cocoa butter and coconut oil. This might sound wonderful, but these can be some of the worst offenders when it comes to clogging hair follicles. These oils, while natural, are unrefined and contain larger sized particles that are considered to be comedogenic, a term we usually only hear when referring to skin care products, meaning that, ultimately, that they will clog pores,” he explains. “You can also combat clogged hair follicles by using a product that works at removing product residue with carbonation. Try Plarmia Spa Cleansing Foam. This mousse-like formula deep cleanses the hair follicle without using harsh detergents or sulphates.”
