Tsitsi (lochokera ku Latin capillus) ndi tsitsi linalake lomwe limagwira ntchito yoteteza mutu ndi khungu. Yopangidwa ndi keratin, ndi yamphamvu kwambiri ndipo imatha kupirira kulemera kwa 100g osasiya.

Tsikuli limangolankhula za mtundu wa anthu. Amakhala ndi kutalika kwakutali komanso kosinthika komanso kuphimba kumutu. Mwa munthu wamkulu wathanzi, pali pafupifupi 150.

Tsitsi limapangidwa ndi puloteni, keratin, yomwe imakhala ndi mphamvu zambiri. Koma mulinso madzi, mafuta acids, melanin, zinc, mavitamini ndi ayironi pang'ono.

Tsitsi limapangidwa ndi gawo lowoneka, tsinde, ndi muzu womwe umakwiriridwa muboola laling'ono, cholumikizira tsitsi.

Ndodoyo imatulukira pamwamba pamutu. Mtundu wake umasiyana kutengera mtundu wa munthu. Zimapangidwa ndi zigawo zitatu: mafuta, ozunguliridwa ndi kotekisi, yomwe imakutidwa ndi cuticle. Otsatirawa amapangidwa ndi maselo osanjikiza omwe apangidwa ngati matailosi padenga: makonzedwe awa amalola kupatukana kwa tsitsilo, lomwe limalepheretsa kuti ligundike. The cuticle ndi dera lomwe lili ndi keratin yambiri, yomwe imalimbitsa tsitsi ndikupangitsa kuti ikhale yolimba kwambiri.

Muzu umayikidwa pansi pa khungu mosavomerezeka. Amamira mumtsitsi, pomwe amapangira tsitsilo. M'munsi mwake muli babu la tsitsi lomwe lili m'munsi mwake, papilla wa tsitsi; Ndi pamlingo uwu pomwe kusinthana kwa michere ndi mpweya wofunikira pakukula kwa tsitsi kumachitika. Pamwambapa babu pali khungu lolimba, lomwe limatulutsa sebum pakuthira kwa tsitsi.

Pansi pa follicle, timapezanso minofu yowongolera. Imachita mgwirizano chifukwa cha kuzizira kapena mantha.

Kuzungulira kwa tsitsi

Tsitsi lonse limabadwa, limakhala ndi moyo ndikumwalira: uku ndi kuzungulira kwa tsitsi. Tsitsi lonse silofanana. Kuzungulira kumatha pafupifupi zaka 3 mpaka 4 ndipo kumakhala magawo atatu:

Gawo la Anagen - Kukula

Tsitsi 85% likukula. Tsitsi limapangidwa pamlingo wa babu ndipo limakula ndikuchulukitsa kwa keratinocytes, maselo omwe amapanga keratin. Ma keratinocyte amachoka pakukula, amalimbikira kuti apange shaft kenako amwalira. Babu la tsitsi limakhalanso ndi mtundu wachiwiri wama cell, ma melanocyte, omwe amapanga melanin, pigment yomwe imayambitsa utoto wa tsitsi. Kukula kwakukula kwa tsitsi ndi 0,9-1,3cm pamwezi. Amasiyana malinga ndi mtundu wa tsitsi, lachangu kwambiri ndi mtundu waku Asia.

Gawo la Catagen - Mpumulo

Nthawi yotchedwa "involution", imatenga milungu iwiri kapena itatu ndipo imakhudza 2% ya tsitsi. Imafanana ndi kupumula kwa follicle: magawano am'magawo amasiya, chovalacho chimafupikira ndikuchepera kukula.

Gawo la Telogen - Kugwa

Ndikutsitsimula kwathunthu kwa tsitsi komwe, pamapeto pake, kumachotsedwa pamutu. Imatha pafupifupi miyezi iwiri ya 2% ya tsitsi. Kenako kuzungulira kumayambiranso, tsitsi latsopano limapangidwa ndi follicle.

Tsitsi

Tsitsi limagwira ntchito yaying'ono yoteteza mutu kumenyedwa.

Mitundu ya tsitsi ndi utoto

Tsitsi lili ndi mawonekedwe osiyanasiyana. Tsinde shaft limathandiza kusiyanitsa iwo:

• gawo lowulungika, lomwe limawonetsa tsitsi losalala, silky ndi wavy,
• Gawo lathyathyathya lomwe limafanana ndi tsitsi lofewa,
• Gawo lozungulira lomwe limapereka tsitsi lolimba, lokhala ndi chizolowezi chovuta.

Palinso kusiyana pakati pa mafuko. Munthu waku Africa waku America awonetsa kuchepa kwa tsitsi, m'mimba mwake, mphamvu, komanso kuthamanga. Kwa munthu wochokera ku Asia, tsitsi limakhala lokulirapo komanso lolimba.

La Mtundu wa tsitsi imayang'aniridwa ndi melanocytes omwe amapanga melanin. Pali mitundu yosiyanasiyana - yachikaso, yofiira, yofiirira ndi yakuda - yomwe pophatikiza imatulutsa utoto. Pankhani ya tsitsi loyera, ma melanocyte sagwiranso ntchito.

Alopecia : amatanthauza kutayika kwa tsitsi kusiya khungu pang'ono kapena poyera. Pali mitundu yosiyanasiyana.

Alopecia pachikwangwani (kapena alopecia areata): amachititsa tsitsi kutayika pa zigamba, nthawi zambiri pamutu. Khungu la chigaza limasungabe mawonekedwe ake abwinobwino, koma limangokhala lopanda tsitsi m'malo.

Kusala (kapena androgenetic alopecia) : amatanthauza kutayika kwa tsitsi kusiya khungu lonse. Amakhudza kwambiri amuna ndipo makamaka amatsimikiziridwa ndi chibadwa.

Zowopsya alopecia : Kutayika kwa tsitsi komwe kumayambitsidwa ndi kuwonongeka kwamuyaya pamutu chifukwa cha matenda akhungu kapena matenda (lupus, psoriasis, lichen planus, etc.).

Mphete : Matenda a khungu ndi tsitsi omwe amayamba chifukwa cha bowa, ma dermatophytes. Matenda a Benign koma opatsirana kwambiri omwe amakhudza ana osakwana zaka 12. Ndiye chifukwa chofala kwambiri cha alopecia mwa ana, koma tsitsi limabwereranso nthawi zambiri.

Effluvium télogène : kutaya tsitsi mwadzidzidzi komanso kwakanthawi chifukwa chakumenyedwa kwakuthupi kapena kwamaganizidwe, mimba, opaleshoni, kuonda kwambiri, kutentha thupi kwambiri, ndi zina zambiri.

Nsonga forked : tsitsi lakunja, dera lolemera kwambiri mu keratin, limadziwika kwambiri ndi zipolowe zakunja ndipo limachepa kumapeto kwa tsitsi. Zipilala za keratin panthawiyo zimakhala mkatikati mwazitsulo, chodabwitsa chotchedwa kugawanika.

Tsitsi lodalala : kuwoneka kowala kwa tsitsi komwe kumawonetsa kusokonekera pakugwira ntchito kwa zotupa zolimbitsa thupi zomwe zili pamlingo wotsatira. Sebum imapangidwa mopitilira muyeso. Amakola fumbi ndi kuipitsa mosavuta, zomwe zimatha kukwiyitsa khungu ndikupangitsa kuyabwa.

Tsitsi louma kapena lofooka: tsitsi lomwe lakalamba msanga kwambiri ndipo keratin yake yatayika. Chifukwa chake, amathyoka mosavuta akamatsuka, makongoletsedwe, kapena akamagona. Zimakhala zovuta mpaka kukhudza, zimakhala zovuta kuzilekanitsa, ndipo malekezero amakhala magawano.

zoopsa : chosaopsa, awa ndi mamba ang'onoang'ono oyera achikopa ofanana ndi masango amtundu wakufa omwe amagwa pamutu. Kuyimitsidwa kosazolowereka kumeneku kumachitika chifukwa cha kupititsa patsogolo kwa maselo a khungu la m'mutu, chifukwa cha kutupa kwake ndi bowa. malassezia (zilipo mwachilengedwe, zimafalikira modabwitsa). Dandruff imakhudza m'modzi mwa anthu awiri ku France.

Seborrheic dermatitis : Matenda akhungu oopsa omwe amadziwika ndi mapangidwe ofiira ofiira ophatikizidwa ndi masikelo (mitundu yazinyalala) pakhungu. Amakhudza kwambiri mbali zamafuta pakhungu, kuphatikiza pamutu.

Nthawi zina kumwa mankhwala ena kumatha kutsitsa tsitsi. Izi ndizochitika ndi mankhwala ena a psychotropic. Tiyeni titchule mwachitsanzo lithiamu yomwe, yomwe idalamulidwa matenda amisala, amadziwika kuti ndi omwe amachititsa alopecia.

Ochepetsa magazi ena, monga warfarin omwe amaperekedwa kwa anthu omwe ali ndi matenda a atrial fibrillation kapena venous thrombosis, mwachitsanzo, amatha kuyambitsa alopecia mwa anthu ena. Nthawi zambiri, kusiya mankhwalawa kapena kuchepetsa mankhwalawo kumapangitsa kuti tsitsi libwerere.

Kuchizidwa ndi chemotherapy kapena radiation radiation kuti muchepetse khansa ndimkhalidwe womwe umadziwika kuti umayambitsa tsitsi komanso tsitsi. Kawirikawiri alopecia wosakhalitsa, tsitsi limakula kumapeto kwa chithandizo.

Kusamvana kwa mahomoni, kutopa, kudya mopanda malire, dzuwa kapena kupsinjika ndizo zinthu zomwe zingakhudze thanzi la tsitsi lathu. Kupewa alopecia sikutheka. Komabe, pali zina zomwe zimathandizira kuti tsitsi likhale ndi thanzi labwino. Kulandira chakudya chopatsa thanzi kumapewa zoperewera ndipo kumapereka zakudya zofunikira pakukongoletsa tsitsi monga zinc, magnesium kapena calcium. Kudya zakudya zokhala ndi mavitamini a B6 (saumoni, nthochi kapena mbatata) kumatha kuteteza kapena kuthandizira kutsuka tsitsi, mwachitsanzo.

Chithandizo cha alopecia

Minoxidil lotion ndi chithandizo chomwe chimachedwetsa kutayika kwa tsitsi ndikulimbikitsa kukula kwa tsitsi. Finasteride imachepetsa kuchepa kwa tsitsi ndipo nthawi zina imalimbikitsa kukonzanso kwa tsitsi.

Kuwunika kowoneka bwino : ndi funso lofanizira mbali ya dazi ndi mawonekedwe owoneka, otchedwa Hamilton osinthidwa ndi Norwood. Kufufuza uku kumapangitsa kuti athe kudziwa kuti ndi milandu iti yomwe ingapindule ndi chithandizo chamankhwala ndipo ndi yani (mitundu yayitali kwambiri).

Chitatu : kuyesa tsitsi pansi pa maikulosikopu kuti muwone muzu, kuyeza m'mimba mwake ndikuyesa kugwa. Amalola kuzindikira zomwe zimayambitsa alopecia pamavuto.

Kusanthula koopsa : Tsitsi limatha kusunga zinthu zomwe timamwa: mowa, cannabis, chisangalalo, cocaine, mankhwala osokoneza bongo, amphetamines, arsenic, mankhwala ophera tizilombo, osokoneza bongo a endocrine… mndandanda ukupitilira. Kuzindikira mankhwala osokoneza bongo ndi mowa kumagwiritsidwa ntchito makamaka pantchito zakuweruza.

Kupaka tsitsi : Opaleshoni yobwezeretsa tsitsi. Zotheka mwa anthu omwe dazi lawo lakhazikika. Izi zimaphatikizapo kutenga gawo la scalp ndi tsitsi ndi mizu kuseli kwa khungu, komwe tsitsi limakonzedwa kuti likhale moyo wawo wonse. Izi zimadulidwa mzidutswa zokhala ndi tsitsi 1 mpaka 5 kenako amalowetsedwa m'malo a dazi.

Mawu akuti "alopecia" amachokera ku Chigriki alopex kutanthauza "nkhandwe". Mawuwa amasankhidwa kutengera kutayika kwa ubweya womwe umakhudza nyamayi nthawi iliyonse yamasika (2).

Tsitsi nthawi zonse limakhala chizindikiro chachinyengo mwa amayi. Kale m'nthano, azimayi aakazi amafotokozedwa kuti anali ndi tsitsi lokongola (Aphrodite ndi tsitsi lake lalitali lalitali, Venus yemwe amasamalira tsitsi lake lomwe…).

Mwa amuna, tsitsi limangokhala chizindikiro cha mphamvu. Tiyeni tigwire nkhani ya Samsoni (7) yemwe amapeza mphamvu zake zapadera kuchokera kutsitsi lake. M'nkhani ya m'Baibulo, amaperekedwa ndi mkazi amene amamukonda yemwe amameta tsitsi lake kuti amuchotsere mphamvu. Mkaidi, amapeza nyonga zonse tsitsi lake litakula.
