Af Line Trier Friis og Mathilde Hermansen, stiftere af Hormonehealthdk<\/a><\/p>\n Resum\u00e9: <\/span><\/b>H\u00e5rtab rammer op mod 50 % af kvinder i overgangsalderen* og er ofte et overset, men psykisk belastende symptom. Ny forskning peger p\u00e5, at h\u00e5rs\u00e6kkene gennemg\u00e5r deres egen form for ‘overgangsalder’, pr\u00e6get af hormonelle og metaboliske forandringer. Fald i \u00f8strogen, progesteron og melatonin samt \u00f8get f\u00f8lsomhed over for DHT (dihydrotestosteron \u2013 et androgen hormon) og oxidativt stress bidrager til h\u00e5rudtynding. Forst\u00e5elsen af disse mekanismer \u00e5bner for nye behandlingsstrategier, der kombinerer hormonel st\u00f8tte, ern\u00e6ring, stressh\u00e5ndtering og topisk behandling.<\/span> <\/span><\/p>\n<\/div>\n Indledning I et nyligt studie<\/strong> offentliggjort i tidsskriftet Biomedicines beskrives det, at nogle kvinder oplever h\u00e5rs\u00e6kkens overgangsalder uafh\u00e6ngigt af den kliniske overgangsalder. Det tyder p\u00e5, at \u00e6ndringer i h\u00e5rs\u00e6kkens stofskifte \u2013 drevet af individuelle faktorer som \u00f8strogenreceptor-respons, genetik og det samlede samfund af mikroorganismer \u2013 kan f\u00f8re til h\u00e5rudtynding, selv f\u00f8r den hormonelle overgangsalder begynder. Dette hj\u00e6lper med at forklare, hvorfor nogle kvinder begynder at bem\u00e6rke h\u00e5rforandringer allerede i perimenopausen eller endda i 30\u2019erne \u2013 l\u00e6nge f\u00f8r deres sidste menstruation. Det forklarer ogs\u00e5, hvorfor h\u00e5rudtynding kan forekomme hos kvinder med normale hormonniveauer.<\/span> \u00d8strogen spiller en afg\u00f8rende rolle for h\u00e5rets sundhed ved at forl\u00e6nge anagenfasen (v\u00e6kstfasen) i h\u00e5rs\u00e6kkene. <\/span><\/p>\n N\u00e5r \u00f8strogenniveauet falder i overgangsalderen<\/strong>, bliver h\u00e5rv\u00e6kstcyklussen kortere, og h\u00e5rs\u00e6kkene kan skrumpe, hvilket resulterer i finere og tyndere h\u00e5r. Kvinder med FPHL (female pattern hair loss) har ofte lavere \u00f8strogenniveauer end kvinder uden h\u00e5rtab.<\/span> \u00d8strogen har ogs\u00e5 antiinflammatoriske egenskaber i hele kroppen \u2013 og h\u00e5rs\u00e6kkene er ingen undtagelse. Derudover fremmer \u00f8strogen vasodilatation (udvidelse af blodkar). N\u00e5r \u00f8strogenniveauet falder, kan blodkarrene i hovedbunden tr\u00e6kke sig sammen, hvilket potentielt reducerer blodtilf\u00f8rslen til h\u00e5rs\u00e6kkene og begr\u00e6nser tilf\u00f8rslen af n\u00e6ringsstoffer og ilt.<\/span> Faldet i \u00f8strogen under overgangsalderen \u00e6ndrer ogs\u00e5 balancen mellem \u00f8strogen og androgener<\/strong> i kroppen, hvilket er en anden mulig \u00e5rsag til h\u00e5rtab \u2013 is\u00e6r hos kvinder, der er f\u00f8lsomme over for DHT (dihydrotestosteron), et kraftigt androgen, der stammer fra testosteron.<\/span> Progesteron<\/strong> har ogs\u00e5 en beskyttende rolle i h\u00e5rv\u00e6kst. Det h\u00e6mmer enzymet 5<\/span>\u03b1<\/span>-reduktase, som omdanner testosteron til DHT \u2013 en forbindelse, der er forbundet med en formindskelse af h\u00e5rs\u00e6kke. N\u00e5r progesteronniveauet falder i overgangsalderen, forsvinder denne beskyttelse, hvilket kan g\u00f8re h\u00e5rs\u00e6kkene mere s\u00e5rbare over for DHT\u2019s virkninger.<\/span> <\/p>\n Melatonin er mest kendt som s\u00f8vnhormonet, men ny forskning viser, at det ogs\u00e5 spiller en vigtig rolle i reguleringen af h\u00e5rv\u00e6kst. H\u00e5rs\u00e6kke har melatoninreceptorer, hvilket tyder p\u00e5, at hormonet har direkte indflydelse p\u00e5 h\u00e5rv\u00e6kstcyklussen. <\/span>Melatoninproduktionen falder med alderen<\/strong> \u2013 is\u00e6r under overgangsalderen \u2013 og dette kan bidrage til h\u00e5rudtynding gennem flere mekanismer:<\/span> <\/span><\/p>\n \ud83d\udd39Regulering af h\u00e5rcyklus<\/strong>: Melatonin forl\u00e6nger anagenfasen (den aktive v\u00e6kstfase i h\u00e5rets livscyklus). N\u00e5r niveauet falder, bliver v\u00e6kstfasen kortere, hvilket giver tyndere og kortere h\u00e5r.<\/span> Kliniske studier med topisk melatonin har vist lovende resultater med \u00f8get h\u00e5rt\u00e6thed og reduceret h\u00e5rtab. Det tyder p\u00e5, at melatonin kan v\u00e6re en effektiv tilgang til at bek\u00e6mpe menopausalt h\u00e5rtab.<\/span> <\/span><\/p>\n L\u00f8sninger *<\/strong>Vil du vide mere om symptomer i overgangsalderen, s\u00e5 l\u00e6s vores opslag her: Vi h\u00e5ber du har f\u00e5et mere viden om <\/span>h\u00e5rets forandringer i menopause-transitionen<\/span> og er blevet nysgerrig p\u00e5 at l\u00e6re endnu mere.

\n<\/strong>N\u00e5r kvinder g\u00e5r i overgangsalderen, forventer de hedeture, nattesved og hum\u00f8rsvingninger. Hvad mange ikke er forberedt p\u00e5, er den uvelkomne overraskelse: tyndere h\u00e5r. Alligevel oplever omkring 50 % af kvinder h\u00e5rtab, n\u00e5r de n\u00e5r overgangsalderen<\/strong> \u2013 og for mange er det et af de mest belastende symptomer i denne livsfase.<\/span> Men er det blot et sp\u00f8rgsm\u00e5l om aldring, eller sker der noget mere komplekst? Ny forskning antyder, at vores h\u00e5rs\u00e6kke m\u00e5ske gennemg\u00e5r deres egen form for ‘overgangsalder’ \u2013 med metaboliske og hormonelle udfordringer, der spejler dem, der sker i resten af kroppen.<\/span> Konceptet om, at h\u00e5rs\u00e6kken oplever sin egen form for overgangsalder, vinder videnskabelig anerkendelse. If\u00f8lge forskere gennemg\u00e5r h\u00e5rs\u00e6kkene \u2013 ligesom kroppen under overgangsalderen \u2013 en systemisk forandring pr\u00e6get af \u00e6ndret stofskifte, nedsat blodgennemstr\u00f8mning og \u00e6ndrede reaktioner p\u00e5 hormonelle signaler.<\/span><\/p>\n

\n\ud83d\udd39Anti-androgene effekter<\/strong>: Nogle studier antyder, at melatonin kan modvirke DHT\u2019s virkning p\u00e5 h\u00e5rs\u00e6kke.<\/span><\/p>\n
