Kukho izigulane ezingenakubalwa ngaphezu kweminyaka ejongene nokugqithiswa komzimba kwiintsuku ezimbalwa emva kokubala imibala yazo . Kukho izizathu ezahlukileyo zezi zinto - eziqhelekileyo zazo ziboya zinoboya. Nangona kunjalo, phantse zonke izigulane ndidibana nazo ziyamangaliswa kukuba ukubala imibala yabo kuya kubangela ukugqithisa ubuso, ingakumbi kuba baye basebenzisa inwele efanayo imibala iminyaka (ngamanye amaxesha namashumi eminyaka) ngaphandle kweengxaki.
Isizathu sokuthi ukugqithisa kokuqala kubakho ebusweni emva kokubala imibala kukuba ulusu ebusweni lucace kakhulu, kwaye lusebenza ngakumbi kunesikhumba esikhwameni. Enyanisweni, isikhumba se-scalp sinqabile, ukuba ukutshintsha kweentlanzi zincinci kuphela kunokubangela ukuba i-scalp ibangele. Ukongeza, umntu unokusebenzisa idayi ekhethekileyo kwiminyaka emininzi engenazo iingxaki-de kube i-immune system iyancatshiswa kwimichiza ngokungabonakaliyo, ukutshiza okanye ukuphazamiseka kwesikhumba - emva kokuba isistim somzimba sisabela kwiikhemikhali ezikhoyo kwizinwele nesikhumba.
Iimpawu zeeNwele zoTywala
Iimpawu zeentloko zetekisi zokutya ziquka ukudibanisa i-dermatitis (ihlazo elibomvu, elibomvu elibomvu) elisoloko lisenzeka ebusweni, iinkophe, indlebe kunye nentamo. Ukuvuvukala ubuso obuninzi kunokuba kwenzeke kunye ne-dermatitis kumnxeba wezinwele, odla ukuphosakela nge-angioedema. I-angioedema , nangona kunjalo, ngokungafani no-dermatitis, ayibomvu, ayifuni, idla ngokuphindaphindiweyo kwelinye icala lobuso ngexesha, kwaye ayifuni okanye iphosa xa i-rash iphelisa.
Izibonakaliso zempatho zobuninzi bezinwele zidla rhoqo kwiintsuku ezi-2 ukuya kwezi-3 emva kokuba umntu ebalabala iinwele zakhe. Nangona kunjalo, iimpawu zingapheli iintsuku ukuya kwiiveki emva kokugqibela umntu odayileyo iinwele.
Izizathu ezine eziqhelekileyo zokuBuquka koMbala weNwele
1. I-Para-Phenylenediamine (PPD). Ikhemikhali enombala obuninzi obunokubangela ukuba i-para-phenylenediamine (PPD) iphendule.
I-PPD ifunyenwe ngaphezu kweyesibini kwesahlulo zeeyunithi zeentloko ezisisigxina kwaye ziphumelela kakhulu ekungeneni kweenwele zentloko kunye ne-follicle, kunye nokubopha kwiiprotheni elukhumbeni. Ezi zimbonakaliso zenza i-PPD i-antigen edibeneyo yokunxibelelana nayo inokukwazi ukunyusa iimpendulo. Ngenxa yoko, amanye amazwe aseYurophu, kuquka iJamani, iFransi neSweden, avalwe iPPD. Uninzi lweentlanzi zamehlo ezibhaliweyo njenge "hypoallergenic" aziyi kuba nePPD njengesithako.
2. Cobalt. I-Cobalt yenye enye ikhemikhali ekhona kwiiyiti ezithile zeentsimbi ezona zizathu eziqhelekileyo zokuphendula ukubala imibala. Le khemikhali isebenza ukubonelela i-pigment kwezinye idayi ezinwele ezimhlophe kunye eziphakathi. Le nto ibangelwa yinto ebangela ukungabikho komdla kwibala, njengoko abantu banokucinga ukuba ukuba bafumana impendulo yeezinwele, kuba kufuneka kube yi-PPD. Nangona kunjalo, umntu oqhekeza i-cobalt uya kusabela kwidayi yeenwele "ze-hypoallergenic" kuba idayi yeenwele iya kuhlala iqukethe i-cobalt, kodwa i-PPD ayikhoyo (isizathu esivakalayo sokuphendula ngombala wezinwele).
3. I-glyceryl thioglycolate. Le khemikhali ifumaneka kwisisombululo esingasigxina esingasetyenziselwa ngokubambisa kunye neenwele zobununu. Ekubeni i-glyceryl thioglycolate ayifumaneki kwiipaneli eziqhelekileyo ukuvavanya udibaniselwano lwe-dermatitis, yinto yokuxilonga ekwazi ukuphosakela lula ngumntu ongenanto okanye umdemokethi owenza ukuvavanya ngenxa yesibambathiso somntu.
Ngoko ke, ukuba umntu usebenzisa isisombululo sokukhawuleza (okanye ukulungisa) iinwele zabo, kunye nombala weenwele, kubalulekile ukuqwalasela zonke iichiza ezinokuba zibangelwa ukuqhuma komzimba komntu.
4. Cocamidopropyl betaine . I-Cocamidopropyl betaine yinto efunyenwe yikhokhonati efunyanwa kwi-shampoos ezininzi, amasobho, kunye nemveliso yokuhlamba. Le khemikhali isebenza njengomntu osebenzayo-oko kuthetha ukuba ivelisa "iimbumba" -impawu zesepha ezininzi ezinika imiphumo yokucoca kwesephu. Ekubeni i-Cocamidopropyl betaine ifumaneka kwi-shampoos ezininzi, yinto ebangelwa yinto yokuqhagamshelana nomdematitis ebusweni.
Kwaye, ngenxa yokuba i-shampoos kunye nezinye iimveliso eziqukethe iCocamidopropyl betaine zifumaneka kwimveliso ye-hairstyling, le michiza ingaba noxanduva lokuphendula emva kokubala imibala.
