Anna Gardell-Olsson

Förbättrade effekten av både schampo och balsam,håret upplevs fylligare och mindre flygigt/statiskt.

Luktar magiskt!

Jag tror inte att det här serumet är 100% match med mitt hår men jag använder det ändå och är nöjd. Det luktar fantastiskt och det är väldigt smidigt att kunna använda i såväl schampoo, balsam eller efter duschen.

Ger hårer en mjuk och bra könsla.


Älskar möjligheten att använda i såväl i schampoo som att kunna ta en pump i håret efter tvätt. Väldigt användbart & god doft

Mange tak!

Jeg har nu modtaget mit shampoo og conditioner. Jeg har dog endnu ikke prøvet det - så jeg må nøjes med at sige, at jeg har fået den fineste service, som jeg nogensinde har fået, på en webshop! 🙏🙏🙏

Dejligt at høre, Lise! ❤️
