Pakhala pali odwala osawerengeka m'zaka zomwe amatha kupweteka nkhope m'masiku ochepa atatha kuwaveka tsitsi lawo . Pali zifukwa zingapo izi - zomwe zimakhala zofiira kwambiri. Ngakhale izi zili choncho, pafupifupi wodwala aliyense yemwe ndimakumana naye akuoneka kuti akudabwa kuti kuyaka tsitsi lawo kungawononge nkhope, makamaka chifukwa chakuti adagwiritsa ntchito tsitsi lomwelo kwa zaka (nthawizina ngakhale zaka makumi) opanda mavuto.
Chifukwa choyamba kuthamanga pamaso pakusaka tsitsi ndiye kuti khungu pamaso ndi lochepa kwambiri, ndipo limakhala lochepetsetsa kwambiri kusiyana ndi khungu pa khungu. Ndipotu, khungu la scalp ndi lakuda kwambiri, kuti maonekedwe a tsitsi lofewa amangowonongeka osati pafupipafupi. Kuonjezerapo, munthu akhoza kugwiritsa ntchito ulusi winawake wa tsitsi kwa zaka zambiri popanda mavuto - mpaka chitetezo cha mthupi chitetezedwe ku mankhwala pogwiritsa ntchito mdulidwe wosazindikiridwa, kupopera kapena kusokonezeka khungu - pambuyo pake chitetezo cha mthupi chimagwira ntchito kwa mankhwala pa tsitsi ndi khungu.
Zizindikiro za Tsitsi Zakudya Zolimbitsa Thupi
Zizindikiro za ubweya wa tsitsi ndi ubweya wothandizira (kuthamanga, kuphulika kofiira) komwe kawirikawiri kumawonekera pamaso, maso, makutu, ndi khosi. Kutupa kwakukulu kwa nkhope kungathenso kuchitika ndi kukhudzana ndi dermatitis ku tsitsi la tsitsi, lomwe nthawi zambiri limasokonezeka chifukwa cha angioedema. Angioedema , komabe mosiyana ndi matenda okhudza dermatitis, sali ofiira, saloledwa, nthawi zambiri amapezeka pambali imodzi ya nkhope pa nthawi, ndipo sichimawoneka kapena kupweteka pamene mphutsi ikuchiritsa.
Zizindikiro za utoto wa utoto kawirikawiri zimapezeka masiku awiri mpaka 3 munthu atayaka tsitsi lake. Komabe, zizindikiro zimatha masiku ambiri mpaka masabata atatha nthawi yomwe munthu amadula tsitsi lake.
Zifukwa Zinayi Zomwe Zimayambira Kujambula Maso
1. Para-Phenylenediamine (PPD). Nsalu ya ubweya wa tsitsi kwambiri yomwe imayambitsa matendawa ndi para-phenylenediamine (PPD).
PPD imapezeka mu magawo awiri mwa magawo atatu pa atatu a tsitsi lalitali ndipo imakhala yothandiza kwambiri pamphuno ndi tsitsi, komanso kumangiriza mapuloteni. Zizindikirozi zimapangitsa PPD kukhala wothandizana kwambiri ndi antigen yomwe ingathe kuchititsa kuti anthu asamayende bwino. Pa chifukwa chimenechi, mayiko ena a ku Ulaya, kuphatikizapo Germany, France, ndi Sweden, aletsa PPD. Madontho ambiri a tsitsi omwe amatchedwa "hypoallergenic" sadzakhala ndi PPD monga chogwiritsira ntchito.
2. Cobalt. Cobalt ndi mankhwala ena omwe amachititsa mtundu winawake wa tsitsi. Mankhwalawa amathandiza kuti pigmentyi ikhale ndi mitundu yambiri ya tsitsi. Izi kawirikawiri zimakhala zosayang'anitsitsa chifukwa cha mtundu wa tsitsi, monga momwe anthu angaganize kuti ngati atayidwa ndi tsitsi la tsitsi, ayenera kuti adakhalapo chifukwa cha PPD. Komabe, munthu wodwala mankhwala a cobalt adzalandirabe chifukwa cha "tsitsi la hypoallergenic" la udzu chifukwa udzu wa tsitsi umakhalabe uli ndi cobalt, koma palibe PPD (chifukwa chodziwika bwino cha kaonekedwe ka tsitsi).
3. Glyceryl thioglycolate. Kachilombo kameneka kamapezeka m'maganizo osatha omwe angagwiritsidwe ntchito pamodzi ndi tsitsi. Popeza glyceryl thioglycolate sichipezeka m'zigawo zowonetsera kuti munthu ayambe kugonana ndi dermatitis, ndi matenda omwe angaphonye mosavuta ndi wotsutsa kapena dermatologist akuyesera chifukwa cha kukhudzana ndi munthu.
Choncho, ngati munthu akugwiritsa ntchito njira yothetsera (kapena kuwongolera) tsitsi lawo, komanso tsitsi la tsitsi, ndi bwino kuganizira mankhwala onse omwe angayambitse kupweteka kwa nkhope.
4. Cocamidopropyl betaine . Cocamidopropyl betaine ndi mankhwala otulutsa kokonati omwe amapezeka m'madzi ambiri, sopo, ndi mankhwala osamba. Mankhwalawa amachititsa kuti tizilombo toyambitsa matenda - timene timatulutsa "mitsempha" - sopo zambiri zomwe zimapereka mankhwala othandizira sopo. Popeza Cocamidopropyl betaine imapezeka m'ma shamposi ambiri, nthawi zambiri zimakhala zosavomerezeka chifukwa chotsutsana ndi dermatitis.
Ndipo, chifukwa mankhwala ndi mankhwala ena omwe ali ndi Cocamidopropyl betaine amapezeka mu zokongoletsera tsitsi, mankhwalawa akhoza kuchitapo kanthu pakatha mtundu wa tsitsi.
