Det rigtige hårserum til hovedbunden – eller til længderne.
»Hårserum« dækker over to forskellige ting: serummer til hovedbunden, der skal støtte hår, som er ved at blive tyndere, og plejeserummer til blanke, smidige længder. Vi forklarer forskellen og anbefaler produkter til begge dele.

LADUTI Hair Serum
Et serum til kvinder og mænd i en 30 ml brun glasflaske med pipette. Du fordeler det i hovedbunden om aftenen, hvor det bliver siddende hele natten. Det kombinerer AnaGain™ og Procapil™, uden minoxidil og uden hormoner; Dermatest® vurderer hudtolerancen som »meget god«.
Ét aktivstof (thiocyanat), dagligt i hovedbunden, uden udskylning. Det er hurtigt overstået. Producenten henviser til anvendelsesobservationer, men uden kontrolgruppe.
Et serum til hovedbunden med plantekomplekset MKMS24, ifølge producenten blandt andet af bambus, timian og linser. Det sprayes på hovedbunden og masseres ind. Producentens store procenttal har vi ikke kunnet genfinde i uafhængige studier.
Et plejeserum til tørre længder, der kommes i håret om aftenen og plejer natten over. Om morgenen føles håret blødere og er lettere at style. Det er ikke beregnet til hårtab.
Et olieserum af tre planteolier, blandt andet arganolie. I fugtigt hår gør det håret lettere at rede ud, i tørt hår giver det glans og tæmmer frizz. Få dråber er nok.
Et serum til hovedbunden bør ikke skylles ud. Jo længere det bliver siddende i hovedbunden, desto bedre – derfor kan vi godt lide serummer til om aftenen.
Dokumentation
Spørg, om der findes studier med en kontrolgruppe. Producentangivelser som »op til 90 %« uden kilde er reklame, ikke dokumentation.
Tolerance
Har du en sart hovedbund, så hold øje med parfume og alkohol, og test nye serummer på et lille område først.
Vægt
Fint hår tåler kun lette plejeserummer i spidserne. Tykt, kruset hår kan godt klare mere olie.
Silikoner
I plejeserummer er de uproblematiske og ofte grunden til glansen. I hovedbunden har de intet at gøre.
Ofte stillede spørgsmål
Hjælper et hårserum mod hårtab?
Et plejeserum til længderne gør ikke. Et serum til hovedbunden med undersøgte aktivstoffer kan støtte hår, der gradvist bliver tyndere, hvis du bruger det regelmæssigt i flere måneder. Hvilke midler vi anbefaler til det, kan du se i vores sammenligning Top 10 midler til hårvækst.
Kan jeg bruge hårserum hver dag?
Serummer til hovedbunden er beregnet til daglig brug. Plejeserummer til længderne er som regel nok efter hårvask eller efter behov – ellers bliver håret tungt.
Hårserum i vådt eller tørt hår?
Plejeserummer beskytter i håndklædetørt hår, før du føner, og virker som finish mod frizz i tørt hår. Serummer til hovedbunden kommer du som regel på en tør hovedbund – følg producentens anvisning.
Hvad er forskellen på hårserum og hårolie?
Hårolier består overvejende af planteolier, plejeserummer ofte af lette silikoner med lidt olie – de lægger sig glattende om håret. Ingen af dem er beregnet til hovedbunden. Læs mere i vores artikel om hårolie.
