人，为什么会有头皮屑？

头皮屑的存在总是令人困扰

大家有没有好奇过头皮屑到底从何而来今天将向大家展示我们为什么会有头皮屑首先让我们认识一下生成头皮屑的“罪魁祸首”：马拉色菌。这是一种酵母菌，存在于我们的头皮上：Hereinthisabundantforest,Malassezia(马拉色菌)isequippedwitheverythingitcouldeverneed.Feastingconstantly,it’sinparadise.Butwait--what’sthis?Infact,

Malasseziaisatypeofyeastthatlivesanddinesonallofourscalps.Andinabouthalfofthehumanpopulation,itsactivitycausesdandruff

(头皮屑).

那么，为什么有些人的头皮屑总是比较多？又该怎样治疗呢？

其实，我们身上总是寄生着许多微生物，马拉色菌也是其中一员。它们寄生在产生毛发的毛囊中，以毛囊分泌的皮脂为食，我们的头皮是我们身体上最油的地方之一，当马拉色菌消耗头皮的油脂时就会产生头皮屑：Wemightconsiderourselvesindividuals,butwe’rereallycolonies.Ourskinhostsbillionsofmicrobes.Malasseziayeastsmakethemselvesathomeonourskinshortlyafterwe’reborn.Follicles(毛囊),thetinycavitiesthatgrowhairsalloverourbody,makeforespeciallypopularlivingquarters.Malasseziaarefondofthesehideoutsbecausetheycontainglands(腺)thatsecrete(分泌)anoilcalledsebum(皮脂)that’sthoughttolubricateandstrengthenourhair.Malasseziaevolvedtoconsumeourskin’sproteinsandoils.Andbecauseofitsmanysebum-secretingfollicles,ourscalpisoneoftheoiliestplacesonourbody—andconsequently,oneoftheyeastiest.Asthesefungifeastonourscalp’soils,dandruffmayform.

马拉色菌通过分泌一种酶来“吃”皮脂，但它们只摄入饱和脂肪，而残留的不饱和脂肪酸就与皮肤作用产生头皮屑：Thisisbecausesebumiscomposedofbothsaturatedandunsaturatedfattyacids.Saturatedfatsneatlypacktogether.Unsaturatedfats,ontheotherhand,containdoublebondsthatcreateanirregularkinkintheirstructure.Malasseziaeatsebumbysecretinganenzyme(酶)thatreleasesalloftheoil’sfattyacids.Buttheyonlyconsumethesaturatedfats,leavingtheunsaturatedonesbehind.Theseirregularlyshapedleftoverssoakintotheskinandpryitsbarrieropen,allowingwatertoescape.

一般而言，我们的皮肤表皮每两到三周会完成一次更新，头皮屑便是那些无法正常成熟分化的细胞团块脱落而成的：Usually,ourskin’soutersurface,orepidermis,completelyrenewsitselfeverytwotothreeweeks,Epidermalcellsdivide,moveoutwards,die,andformtheskin’stoughouterlayer,whichgraduallyshedsoffinsinglecellsfartoosmalltosee.

因此，为了减少头皮屑，我们可以使用含抗真菌成分的洗发水：ThisishowMalassezia’svoraciousappetiteandourbodiesreactiontoitsby-productsleadtodandruff.Currently,
