The 'Curly Girl' method (CGM) and its restrictive approaches (banning sulfates/silicones, avoiding traditional washing) are often presented as universal dogmas, yet they prove ill-suited, and sometimes counterproductive, for many individuals who benefit more from regular scalp cleansing and a flexible approach.

The community is converging on a rejection of the rigidity of the CGM, favoring a personalized approach over dogma. Scientifically, sulfates are effective cleansing agents (surfactants) whose use depends on the nature of the scalp: avoiding them systematically can lead to sebum buildup and hair health issues, as confirmed by general dermatological sources on the importance of scalp hygiene. Silicones are not inherently harmful; they are smoothing agents whose impact varies depending on hair texture (and their water solubility). The idea that parabens or silicones are toxins dangerous to hair is based more on belief than solid clinical evidence, as these ingredients are widely regulated and validated for safe cosmetic use. 'NoPoo' (no shampoo) methods lack robust scientific evidence and carry risks of contact dermatitis or infections due to unsterilized homemade preparations. In summary, while the CGM provides useful techniques (such as hydrating ends), the systematic banning of ingredients is a marketing exaggeration without universal foundation.
