Ndikofunika kuzindikira kuti zosakanizazi sizimalowa mkati mwa khungu kapena mumtundu wa tsitsi. Amakhala kunja, kupanga filimu yopyapyala kwambiri pamtunda wawo. Kotero sipangakhale zotsatira zoipa pa zigawo zakuya za khungu kapena kuwonongeka kwa tsitsi kuchokera mkati! Komabe, chinali chidziwitso ichi chomwe chinatsogolera ku nthano yachiwiri: kuti silicones amayenera "kufota" mbali zonse za mankhwala, kuwalepheretsa kupuma, potero kuwononga khungu ndi tsitsi kuchokera kunja. Sizoona! Wosanjikiza wopangidwa ndi woonda mokwanira kuti alole kutuluka kwaulere kwa mpweya kapena madzi makamaka. Choncho, sikuti amangofinya khungu kapena tsitsi, komanso samatsekera pores. Kuonjezera apo, "kupuma pakhungu" ndi mawu ophweka kwambiri omwe alibe chidziwitso chenicheni pazochitika za thupi. Khungu silingapume; ndondomeko yonseyi ikukhudza kusinthana kwa gasi komwe kumachitika kudzera mu zigawo zake. Ndipo izi, monga tanenera kale, sizimakhudzidwa ndi ma silicones.

Nthano ina ndi yakuti silikoni yogwiritsidwa ntchito pa tsitsi imamatira kwambiri kwa iwo, potero imalemera kwambiri ndikulepheretsa kulowa kwa zakudya mu tsitsi. Izinso sizolakwika. Ma silicones opezeka mu ma shampoos, zowongolera kapena zopangira tsitsi zimasiya filimu yoonda kwambiri. Komanso, monga momwe zilili ndi ma volatiles omwe tawatchulawa, amatha kusanduka nthunzi paokha. Nthawi zambiri, ma silicones owuma amagwiritsidwa ntchito posamalira tsitsi, zomwe sizimapanga chotchinga chomata, chamafuta. Mosiyana ndi; kapangidwe kawo ndi kosangalatsa kukhudza, tsitsi limakhala losalala, lonyezimira komanso lotayirira.
