Ntau lab tus tib neeg nyob ib ncig ntawm lub ntiaj teb no ntsiag to soj ntsuam lawv cov plaub hau hauv chav dej iav. Thinning sideburns, widening partings, thiab cov plaub hau poob tseem ceeb tom qab da dej-cov cim niaj hnub no tau ua rau kev lag luam tu plaub hau rau hauv kev lag luam thoob ntiaj teb. Txawm li cas los xij, thaum cov tshuaj zawv plaub hau cog lus ci thiab txias cog lus cog lus smoothness, cov kws tshawb fawb hais tias zaj dab neeg tiag tiag ntawm cov plaub hau noj qab haus huv mus deb dhau qhov ntawd. Ntau tus kws tshawb fawb tau tsom mus rau "hair follicle microenvironment"-ib txoj kab ke lom neeg uas tuaj yeem txiav txim plaub hau kev loj hlob, tsis muaj zog, thiab txawm tias poob.
Tau ntau xyoo lawm, cov neeg siv khoom feem ntau -qib cov khoom tu plaub hau tau tsom rau cov plaub hau pom. Txawm li cas los xij, cov strands no yog cov kab mob lom tuag, feem ntau yog tsim los ntawm keratin. Thaum cov plaub hau loj tuaj ntawm tawv taub hau, nws tuaj yeem coated, ntxiv dag zog, lossis kho kom zoo nkauj -tab sis nws tsis tuaj yeem "kho tau tiag tiag." Kev ua kom muaj zog thiab muaj zog tshwm sim hauv qab ntawm daim tawv nqaij, hauv cov kab mob me me hu ua plaub hau follicles.
Txhua lub hauv paus plaub hau yog lub Hoobkas me me. Ntawm nws lub hauv paus yog cov dermal papilla, ib pawg ntawm cov hlwb tshwj xeeb uas tswj cov plaub hau kev loj hlob. Cov txheej txheem ib puag ncig muaj xws li cov qia hlwb, cov hlab ntsha, lub cev tiv thaiv kab mob, thiab cov teeb liab molecule. Cov khoom no ua ke ua rau cov plaub hau follicle microenvironment-ib txoj kev sib txuas uas tswj cov plaub hau kev loj hlob, so, thiab ua ntu zus.
"Cov hauv paus plaub hau tsis ua haujlwm hauv kev sib cais," ntau tus kws tshawb fawb dermatology piav qhia. "Lawv teb rau cov tshuaj hormones, oxidative kev nyuaj siab, o, thiab cov khoom noj khoom haus. Thaum lub microenvironment tsis zoo, cov plaub hau kev loj hlob qeeb lossis txawm tias nres."
Ib qho kev cuam tshuam loj tshaj plaws yog kev cuam tshuam ntawm dihydrotestosterone (DHT), ib qho tshuaj hormones cuam tshuam nrog cov plaub hau poob ntawm cov txiv neej thiab poj niam. Hauv cov tib neeg uas muaj caj ces, DHT khi rau cov receptors hauv cov hauv paus plaub hau, ua rau lawv maj mam txo qis. Nyob rau tib lub sij hawm, tuab terminal plaub hau ua nyias thiab luv, nws thiaj li tig mus rau yuav luag tsis pom filaments. Thaum cov tshuaj xws li minoxidil thiab finasteride tau ua haujlwm ntawm qee yam ntawm cov txheej txheem no, cov kws tshawb fawb tam sim no tab tom tshawb xyuas cov tswv yim dav dua los tiv thaiv lossis kho qhov sib npaug sab hauv ntawm cov hauv paus plaub hau.
Cov kev tshawb fawb tam sim no qhia txog ntau yam tseem ceeb ntawm cov plaub hau follicle microenvironment zoo:
1. Kev sib txuas lus ntawm tes thiab kev loj hlob: Cov plaub hau kev loj hlob nyob ntawm qhov tseeb intercellular signaling. Kev loj hlob yam xws li epidermal growth factor (EGF) thiab transforming growth factor (TGF) pab tswj cell proliferation thiab sib txawv nyob rau hauv cov plaub hau follicle. Kev cuam tshuam hauv cov teeb liab no cuam tshuam lub follicle lub peev xwm rov tsim dua tshiab. Ib tiam tshiab ntawm bioactive compounds, suav nrog qee cov peptides me me, tab tom kawm vim tias lawv tuaj yeem khi rau cov receptors ntawm tes thiab txhawb txoj kev sib txuas lus no.
2. Cov ntshav ncig thiab khoom noj khoom haus: Zoo li txhua yam ntaub so ntswg, cov hauv paus plaub hau xav tau cov pa oxygen thiab cov as-ham. Cov ntshav khiav tsis zoo, kev ntxhov siab ntev, lossis qhov mob tuaj yeem txwv cov ntshav ncig ntawm cov hauv paus hniav. Txhim kho microcirculation txhim kho cov khoom noj khoom haus, yog li txhawb cov plaub hau kom muaj zog. Qhov no yog ib qho laj thawj vim li cas tawv taub hau zaws, kev tawm dag zog, thiab qee yam khoom siv tshuaj pleev ib ce tau hais ntau zaus thaum tham txog kev noj qab haus huv ntawm cov plaub hau.
3. Oxidative Stress thiab Inflamation: Ib puag ncig muaj kuab paug, UV hluav taws xob, kev haus luam yeeb, thiab kev ntxhov siab ntawm lub hlwb tag nrho ua rau cov dawb radicals ntau lawm. Ntau dhau oxidative kev nyuaj siab ua rau cov plaub hau follicle hlwb thiab accelerates plaub hau laus. Cov tswv yim Antioxidant-txawm yog los ntawm kev noj zaub mov, kev ua neej nyob, lossis kev npaj tshuaj pleev ib ce- tau lees paub tias yog ib feem ntawm kev saib xyuas tawv taub hau.
4. Stem Cell Activity Nyob rau hauv plawv ntawm txhua lub hauv paus plaub hau lies ib tug reservoir ntawm qia hlwb lub luag hauj lwm rau pib tshiab kev loj hlob mus. Yog tias qia cell ua haujlwm poob qis, cov plaub hau ceev yuav maj mam txo. Cov kws tshawb fawb tab tom tshawb nrhiav txoj hauv kev los txhawb cov qia cell tseem ceeb hauv cov plaub hau follicle microenvironment, tab sis feem ntau txoj hauv kev tseem nyob rau theem pib ntawm kev tshawb fawb.
Qhov kev hloov pauv no hauv microenvironment- kev xav centric qhia txog kev hloov pauv dav dav hauv cov kab mob dermatology: los ntawm kev kho saum npoo mus rau cellular- kev cuam tshuam theem. Cov kws tshawb fawb tsis tau tsom mus rau yuav ua li cas los npog lossis ua kom cov plaub hau tuab uas twb muaj lawm, tab sis theej rau kev ncua lub neej ntawm cov hauv paus plaub hau.
Cov cwj pwm niaj hnub kuj ua lub luag haujlwm tseem ceeb. Cov plaub hau nruj, siv cov cuab yeej ua kom sov ntau dhau, kev kho tshuaj hnyav, thiab ua rau tawv taub hau ntev tuaj yeem cuam tshuam qhov sib npaug ntawm cov hauv paus plaub hau. Hloov pauv, kev ntxuav kom huv, txo qis, tiv thaiv lub hnub, thiab tswj kev noj qab haus huv tag nrho pab txhawb cov tawv taub hau bio-ecosystem.
Khoom noj khoom haus tseem ceeb sib npaug. Kev noj zaub mov kom txaus ntawm cov protein, hlau, zinc, vitamin D, thiab fatty acids tseem ceeb pab txhawb rau cov plaub hau follicle. Kev noj zaub mov ntau dhau lossis kev noj zaub mov tsis txaus feem ntau cuam tshuam nrog cov plaub hau poob, qhia txog kev sib txuas ncaj qha ntawm kev noj qab haus huv tag nrho thiab tawv taub hau.
Qhov tseem ceeb, cov kws tshaj lij ceeb toom tawm tsam kev ntseeg hauv txhua txoj hauv kev zoo nkauj plaub hau regrowth. Cov plaub hau kev loj hlob yog ib qho qeeb, cyclical txheej txheem; Cov kev hloov tseem ceeb feem ntau yuav siv sij hawm ntau lub hlis kom tshwm sim.
Kev txhim kho plaub hau yuav siv sij hawm. Novel peptides thiab cov qauv tsim qib siab tau pom cov lus cog tseg hauv chav kuaj, thiab nyob rau xyoo tas los no, cov khoom muaj peptide hu ua PTD-DBM tau txais kev pom zoo. Raws li ib qho tshiab los tiv thaiv-cov plaub hau poob active ingredient, nws txhim khu cov plaub hau ceev thiab lub zog los ntawm kev txhawb cov plaub hau follicle cell proliferation thiab sib txawv, yog li ua kom cov zaub mov nyob ib ncig ntawm cov hauv paus plaub hau. Cov kev tshawb fawb pom tias hom peptide no muaj qhov hnyav me me, biocompatibility zoo, thiab tuaj yeem nkag mus rau ntawm daim tawv nqaij zoo thiab ua ncaj qha rau ntawm cov plaub hau follicle. Nws kuj ntseeg tau tias tswj cov plaub hau- poob- cuam tshuam rau qee yam. Raws li kev tshawb fawb txog qhov tob zuj zus, nws lub peev xwm rau kev siv hauv kev kho tawv nqaij thiab tawv taub hau kev noj qab haus huv tsim nyog tau txais kev saib xyuas txuas ntxiv, thiab cov ntaub ntawv kho mob loj - cov ntaub ntawv txuas ntxiv mus ntxiv. Peb txhawb kom cov neeg siv khoom saib cov khoom tshiab nrog tus cwj pwm zoo thiab muaj kev xav zoo.
Txawm li cas los xij, kev tshawb fawb txog kev tshawb fawb tseem ceeb. Cov kws tshawb fawb tau tshawb pom txoj hauv kev tshiab los tiv thaiv thiab kho cov teeb meem plaub hau los ntawm kev saib cov tawv taub hau ua ib qho chaw nyob, es tsis yog qhov chaw rau cov tshuaj pleev ib ce. Cov plaub hau follicle microenvironment moj khaum pab piav qhia vim li cas qee tus neeg teb tau zoo rau kev cuam tshuam thaum lwm tus muaj kev txwv tsis pub muaj kev cuam tshuam -nyob ntawm lawv cov yam ntxwv lom neeg.
Nyob rau hauv ib lub sijhawm ntawm kev nce "kev ntxhov siab ntawm plaub hau," qhov kev nkag siab tob tob ua rau cov tswv yim pom tseeb thiab kev cia siab. Kev tu plaub hau yuav pib nrog cov tshuaj zawv plaub hau ntawm lub txee, tab sis nws lub hauv paus yog nyob rau hauv lub microscopic network ntawm cov hlwb hauv qab ntawm daim tawv nqaij. Tiv thaiv cov ntshav ncig, txo qhov mob, ntsuas cov tshuaj hormones, thiab txhawb kev sib txuas lus ntawm tes yuav yog qhov tseem ceeb tshaj qhov ci ntsa iab.
Thaum kawg, cov lus tshawb fawb yog qhov yooj yim: cov plaub hau noj qab haus huv zoo li qub; nws tsis glued rau. Qhov kev sib ntaus sib tua tiag tiag rau cov plaub hau tsis yog cov plaub hau uas peb tuaj yeem pom, tab sis tawv taub hau tsis pom microenvironment.
Raws li kev tshawb fawb nce ntxiv, kev tu plaub hau yav tom ntej yuav tsis yog hais txog kev zais yooj yim tab sis hais txog kev saib xyuas tawv taub hau ntau yam ntxwv lom neeg. Qhov kev hloov pauv no tuaj yeem yog qhov tseem ceeb rau ntau lab tus tib neeg txhawj xeeb txog lawv cov plaub hau.
