Izinwele zezinwele ziyizimbobo ezincane, ezinjengephakethe esikhwameni sethu. Njengoba igama liphakamisa, zikhulisa izinwele. Umuntu ovamile unezicucu zezinwele ezingaba ngu-100 000 ekhanda kuphela, ngokusho kwe-American Academy of Dermatology. Sizohlola ukuthi ziyini izintambo zezinwele nokuthi zikhula kanjani izinwele.

I-anatomy ye-follicle

I-follicle yezinwele isakhiwo esime emhubheni ku-epidermis (ungqimba olungaphandle) lwesikhumba. Izinwele ziqala ukukhula ngaphansi kwezinwele. Impande yezinwele yakhiwe ngamaseli wamaprotheni futhi wondla ngegazi elivela emithanjeni yegazi eseduze.

Njengoba kwenziwa amangqamuzana amaningi, izinwele zikhula ziphume esikhunjeni bese zifinyelela ngaphezulu. Izindlala ze-Sebaceous eziseduze nezinsimbi zezinwele zikhiqiza uwoyela, ondla izinwele nesikhumba.

Umjikelezo wokukhula kwezinwele

Izinwele zikhula zivela kuma-follicles ngemijikelezo. Kunezigaba ezintathu ezihlukene zalo mjikelezo:

• Isigaba se-Anagen (ukukhula). Izinwele ziqala ukukhula kusukela empandeni. Lesi sigaba imvamisa sithatha phakathi kweminyaka emithathu nesikhombisa.
• Isigaba seCatagen (sesikhashana). Ukukhula kwehla futhi i-follicle iyancipha kulesi sigaba. Lokhu kuthatha izinyanga ezimbili kuya kwezine.
• Isigaba seTelogen (sokuphumula). Izinwele ezindala ziyawa futhi izinwele ezintsha ziqala ukukhula zisuka esihlokweni esifanayo sezinwele. Lokhu kuthatha izinyanga ezintathu kuya kwezine.

Ngokusho kwe-a, ucwaningo lwakamuva luphakamise ukuthi izintambo zezinwele azikho nje "ukuphumula" 'ngesikhathi sesigaba se-telogen. Umsebenzi omningi weselula wenzeka phakathi nalesi sigaba ukuze izicubu zikwazi ukuvuselela futhi zikhule izinwele eziningi. Ngamanye amagama, isigaba se-telogen sibalulekile ekwakheni izinwele ezinempilo.

Ama-follicles ahlukene ahamba ngezigaba ezahlukahlukene zomjikelezo ngasikhathi sinye. Amanye ama-follicles asesigabeni sokukhula kanti amanye angaba sesigabeni sokuphumula. Ezinye zezinwele zakho kungenzeka zikhula, kanti ezinye ziyawa.

Ngokuya nge-American Osteopathic College of Dermatology, umuntu ojwayelekile ulahlekelwa yizinwele ezingaba yikhulu ngosuku. Mayelana nezinwele zezinwele zakho zisesigabeni se-anagen nganoma yisiphi isikhathi.

Impilo ye-follicle

Ngokwesilinganiso, izinwele zakho zikhula cishe isigamu se-intshi inyanga ngayinye.Izinga lokukhula kwezinwele zakho lingathinteka ngeminyaka yakho, uhlobo lwezinwele, nempilo yakho yonke.

Izinhlayiya zezinwele azibhekene nje nokuthi izinwele zakho zikhula kangakanani, ziphinde zibe nomthelela ekutheni izinwele zakho zibukeka kanjani. Ukuma kwe-follicle yakho kunquma ukuthi izinwele zakho zigoge kangakanani. Izindilinga eziyindilinga zikhiqiza izinwele eziqondile ngenkathi izintambo ezi-oval zikhiqiza izinwele ezishintshayo.

Izinwele zezinwele nazo zidlala indima ekunqumeni umbala wezinwele zakho. Njengesikhumba, izinwele zakho zithola i-pigment yayo ebusweni be-melanin. Kunezinhlobo ezimbili ze-melanin: i-eumelanin ne-pheomelanin.

Izakhi zakho zofuzo zinquma ukuthi unayo i-eumelanin noma i-pheomelanin, nokuthi unengakanani i-pigment ngayinye onayo. Inala ye-eumelanin yenza izinwele zibe mnyama, inani elilinganisiwe le-eumelanin lenza izinwele zibe nsundu, kanti i-eumelanin encane kakhulu yenza izinwele zibe blonde. IPheomelanin yona yenza izinwele zibe bomvu.

Le melanin igcinwa kumaseli ezinwele zezinwele, abese enquma umbala wezinwele. Amafolishi akho angalahlekelwa amandla awo okukhiqiza i-melanin njengoba ukhula, okuholela ekukhuleni kwezinwele ezimpunga noma ezimhlophe.

Uma izinwele zikhishwa esihlokweni sezinwele, zingaphinde zikhule. Kungenzeka ukuthi i-follicle eyonakele izoyeka ukukhiqiza izinwele. Izimo ezithile, njenge-alopecia, zingadala ukuthi amafollicles ayeke ukukhiqiza izinwele ngokuphelele.

Izinkinga ezinezinwele zezinwele

Izimo eziningana zezinwele zidalwa yizinkinga ngezinwele zezinwele. Uma ucabanga ukuthi unesimo sezinwele, noma uma unezimpawu ezingachazeki njengokulahleka kwezinwele, kungcono ukuxhumana nodokotela wesikhumba.

I-Androgenetic alopecia

I-Androgenetic alopecia, eyaziwa ngokuthi yi-baldness yephethini lesilisa lapho yethula emadodeni, yisimo esithinta umjikelezo wokukhula kwezinwele zezinwele ekhanda. Umjikelezo wezinwele uyehla futhi ube buthakathaka, ekugcineni ume ngokuphelele. Lokhu kubangela ukuthi izintambo zingakhiqizi izinwele ezintsha.

Ngokwe-U.S National Library of Medicine, abesilisa abayizigidi ezingama-50 nabesifazane abayizigidi ezingama-30 bayathinteka yi-androgenetic alopecia.

I-Alopecia areata

I-Alopecia areata yisifo esizimele. Amasosha omzimba enza amaphutha ezinwele zamaseli angaphandle futhi awahlasele. Imvamisa kubangela ukuthi izinwele ziwele kuma-clumps. Kungaholela ku-alopecia universalis, okuwukulahleka okuphelele kwezinwele emzimbeni wonke.

Alikho ikhambi elaziwayo le-alopecia areata okwamanje, kepha imijovo ye-steroidal noma ukwelashwa okunezindaba kunganciphisa ukulahleka kwezinwele.

I-folliculitis

I-folliculitis ukuvuvukala kwezinwele zezinwele. Kungenzeka noma kuphi lapho kukhula khona izinwele, kufaka phakathi:

• isikhumba sekhanda
• imilenze
• amakhwapha
• ubuso
• izingalo

I-folliculitis ivame ukubukeka njengokuqubuka kwamaqhuqhuvana amancane esikhunjeni sakho. Amabhampa kungenzeka abomvu, abe mhlophe, noma aphuzi futhi angaqukatha ubomvu. Imvamisa, i-folliculitis iyaluma futhi ibuhlungu.

I-folliculitis ivame ukubangelwa ukutheleleka kwe-staph. I-folliculitis ingaphela ngaphandle kokwelashwa, kepha udokotela angakuxilonga futhi akunikeze nemithi yokusiza ukuyilawula. Lokhu kungafaka ukwelashwa ngezihloko noma imishanguzo yomlomo yokwelapha imbangela yokutheleleka nokunciphisa izimpawu.

I-Telogen effluvium

I-Telogen effluvium iyindlela yesikhashana, kodwa ejwayelekile yokulahleka kwezinwele. Umcimbi ocindezelayo ubangela ukuthi izintambo zezinwele zingene esigabeni se-telogen ngaphambi kwesikhathi. Lokhu kubangela ukuthi izinwele zinciphe futhi ziwe.

Izinwele zivame ukuwa ngamachashazi ekhanda, kepha ezimweni ezimbi kakhulu, zingawa kwezinye izindawo emzimbeni, kufaka phakathi imilenze, amashiya, nasesifundeni.

Ukucindezeleka kungabangelwa:

• isehlakalo esibuhlungu emzimbeni
• ukubeletha
• umuthi omusha
• ukuhlinzwa
• ukugula
• ushintsho lokuphila olunengcindezi

Ukushaqeka komcimbi kudala ushintsho kumjikelezo wokukhula kwezinwele.

I-Telogen effluvium ivame ukuba yesikhashana futhi ayidingi ukwelashwa. Kodwa-ke, kungcono ukukhuluma nodokotela wesikhumba uma ucabanga ukuthi une-telogen effluvium, ngoba bazodinga ukukhipha ezinye izimbangela.

Ukuvuselelwa kwezinwele

Uma unezimo ezifana ne-alopecia noma i-balding, ungahle uzibuze ukuthi kungenzeka yini ukuvuselela uboya bezinwele ukubuyisa izinwele.

Uma i-follicle ilimele, akunakwenzeka ukuyivuselela. Okungenani, okwamanje asazi ukuthi singayivuselela kanjani kabusha.

Kodwa-ke, olunye ucwaningo olusha lwe-stem cell lunikeza ithemba. Kutholwe indlela entsha yokuvuselela izintambo zezinwele ezifile noma ezilimele. Kodwa-ke, le ndlela yokwelashwa ayikahlolwa kubantu futhi ayikavunywa yi-Food and Drug Administration (FDA).

Okubalulekile

Izinwele zakho zezinwele zibhekele ukukhula kwezinwele, okwenzeka ngemijikelezo yezigaba ezintathu ezihlukile. Lezi zintambo nazo zinquma uhlobo lwezinwele zakho.

Uma konakele, izintambo zingayeka ukukhiqiza izinwele, futhi umjikelezo wokukhula kwezinwele zakho ungancipha. Uma unokukhathazeka mayelana nokukhula kwezinwele zakho, khuluma nodokotela wesikhumba.
