Nyenyezi yosamalira bwino kuyambira kumayambiriro kwa zaka za m'ma 2000, kuwongola kwa Brazil kuli ndi otsatira ambiri omwe ali ndi tsitsi lopanduka. Ngati chilango chake chikusokonekera, tikudziwa tsopano kuti mankhwalawa ndi opanda vuto ... Muli chiyani? Ndi zowopsa zotani kwa tsitsi komanso thanzi?

Kuwongola ku Brazil ndi njira yaukadaulo yosamalira tsitsi, yomwe monga dzina limatchulira imachokera ku Brazil. Amatchedwanso keratin smoothing, amakhala ndi jekeseni wamadzimadzi opangidwa ndi keratin wokhazikika mkati mwa tsitsi, atatsegula kale mamba. Kenako, mamba awa amatsekedwa panthawi yosalala ndi mbale zotenthetsera. Keratin yomwe imagwiritsidwa ntchito kusalaza ku Brazil imatha kupezeka kuchokera ku mapuloteni a masamba (soya kapena tirigu) kapena nyama (kuchokera ku nthenga, nyanga, ziboda). , tsitsi la nyama zambiri). Pambuyo pa mankhwalawa, tsitsi lonse limakhala losalala komanso losavuta, lowala, lamphamvu komanso lodziletsa, choncho kupambana kwake.

Kuwongola ku Brazil kumachitika munjira zitatu:

• sitepe yotsiriza: tsitsi kuwongoka chingwe ndi chingwe ntchito kutentha mbale pa 230 ° C, amenenso zimathandiza kutseka mamba ndi kuvala tsitsi. Mankhwalawa amatha kukhala pakati pa 2:30 ndi maola 5 malingana ndi makulidwe ndi kutalika kwa tsitsi;
• Choyamba, tsitsi limatsukidwa mosamala pogwiritsa ntchito shampoo yotchedwa kuwunikira, pa pH yofunikira, yomwe imatsegula masikelo kuti ikonzekere kulandira chithandizo cha keratin;
• ndiye, mankhwala osalala amagwiritsidwa ntchito ku tsitsi lonyowa, chingwe ndi chingwe, popanda kukhudza muzu ndipo amagawidwa mofanana pamtunda wonse wa tsitsi. Chogulitsacho chiyenera kukhala ndikuchitapo kanthu kwa ¼ ya ola pansi pa chipewa chotenthetsera, musanawunike tsitsi.

Zomwe zimagwiritsidwa ntchito powongola ku Brazil zimakhala - kuwonjezera pa keratin zomwe zimapangitsa kuti zikhale zopambana - formalin, yotchedwanso formaldehyde. Ndi iye amene ali ndi udindo wowongolera chithandizo chamankhwala koma ndi iyenso amene amayambitsa mikangano. Formalin imatha kuyambitsa kusintha kwa tsitsi pakapita nthawi komanso kukulitsa tsitsi.

Chodetsa nkhaŵa china: sitepe yotsiriza, yomwe imakhala ndi kuwongola tsitsi ndi mbale zotentha zomwe zimafika kutentha kwa madigiri 230 Celsius, zikhoza kuwononga tsitsi labwino, losalimba, lamitundu kapena lopaka.

Kuphatikiza apo, kutengera ma salons okonzera tsitsi, kusakaniza komwe kumagwiritsidwa ntchito pakuwongola ku Brazil kumatha kukhala ndi silicone ndi / kapena parafini. Zinthu ziwiri zomwe zimatsekeka zimapatsa tsitsi chithunzithunzi chabodza cha thanzi, koma pochita zinthu zimafooketsa ndikuchepetsa kuwala kwake.

Pomaliza, pambuyo kuwongola ku Brazil, ndikofunikira kugwiritsa ntchito ma shampoos opanda sulfate kuti mutsimikizire kuti kusalaza kwanthawi yayitali, komanso koposa zonse kusunga tsitsi.

Vuto: ngati sitepe iyi pambuyo pa chithandizo imanyalanyazidwa - zomwe nthawi zambiri zimachitika chifukwa chakuti mankhwalawa ndi osowa komanso okwera mtengo - chiopsezo ndi kufooketsa tsitsi lomwe limapangitsa kuti likhale lolimba, louma ndi kugwa kwambiri.

Kupatula vuto la kuwongola mobwerezabwereza ku Brazil pamtundu wa tsitsi, lina ndi lovuta kwambiri: zotsatira za formaldehyde pa thanzi.

Formalin yomwe ili m'zinthu zowongola zaku Brazil idayikidwa mu 2005 ndi WHO ngati chinthu chowopsa komanso chowopsa. Malinga ndi Brazilian Health Security Agency (ANVISA), kuopsa kwa kugwiritsa ntchito formalin ndi zenizeni ndipo kumatha kuchoka pakhungu, mpaka ku zovuta za kupuma kudzera pachiwopsezo chowonjezeka cha khansa yapakhosi mwa odwala. ometa tsitsi pachiwonetsero. Pazifukwa izi, keratin yogwiritsidwa ntchito posalala sayenera 0,2% formaldehyde.

M'malo mwake, izi sizimalemekezedwa ndipo zinthu zina zimakhala ndi zambiri.

Kafukufuku waku Germany yemwe adachitika mu 2013 adasanthula zinthu zingapo zowongoka zaku Brazil, ndipo zidawonetsa kuti zambiri mwazo zinali ndi formaldehyde pafupifupi 1,46% mpaka 5,83%! Mitengo ndi yokwera kwambiri kuposa momwe thanzi likufunira.

Chifukwa cha formalin yomwe ili nayo, nthawi zambiri mopitilira muyeso waku Europe, kusalaza kwa ku Brazil sikuletsedwa kwambiri kwa amayi apakati. Izi zimaganiziridwa kuti pamlingo waukulu, zomwe zimayambitsa kuwonongeka kwa mwana wosabadwayo.

Palibenso kusalaza kwa ku Brazil kwa ana, omwe kupuma kwawo kochepa kumawapangitsa kukhala okhudzidwa kwambiri ndi zinthu zapoizoni.

Anthu omwe ali ndi mphumu ndi zowawa ayenera kupewa chisamaliro chamtunduwu nthawi zonse.
