In an interview a dermatologist from the Mount Sinai hospital in New York talks: absolutely not advised to abstain from any type of washing, but the use of alternative products combined with at least one or more treatments a week can help keep the hair clean. However, the advice is always to have a specialist study his case.
During the interview the effects of a past year are described without the hair touching water, effects that can be foreseen with a bit of imagination: ranging from the accumulation of oil and sebum secreted by the scalp, which in turn captures the dirty from the surrounding environment and leads to the proliferation of bacteria, ending with the consequent appearance of infections at the follicles, which over time risk becoming clogged.
However, the forecast concerns a scenario of absolute abstention from washing; at the same time, the content cites techniques used by those who follow the principles of the no-poo movement in a less rigid way - such as bicarbonate washing - considered suitable for use several times a week.

After a period of adjustment lasting a couple of weeks, at the end of the test the hair was soft and odor-free, even if objectively more difficult to treat due to the difficult application of the compound. Moreover, the phenomenon has become so widespread that even industrial shampoo companies could not avoid confronting it, those who devised "low poo" versions of their products, that is, free of surfactants and foam-generating ingredients, those who even set up web pages. in which he exposes his position - not exactly disinterred - contrary to the principles and methods underlying the movement.
