Seitdem ich das Serum verwende, sind meine Haare viel dichter. Kein Haarbruch mehr und die Babyhaare wuchsen nach der Schwangerschaft sehr schnell nach.
Ich liebe das IR Clinical Serum! Meine Haare fühlen sich kräftiger an und ich habe das Gefühl, dass sie insgesamt gesünder aussehen. Besonders auf meiner Kopfhaut fühlt es sich sehr angenehm an und gehört inzwischen fest zu meiner Routine.
Manchmal habe ich allerdings den Eindruck, dass meine Haare etwas schneller nachfetten, wenn ich zu viel Produkt verwende. Deshalb nutze ich lieber etwas weniger. Trotzdem möchte ich nicht mehr darauf verzichten, weil ich die Wirkung einfach liebe.🌿
Je crois que mes cheveux ont décidé de faire leur comeback, sans me prévenir !
Après plusieurs mois avec le IR Clinical Serum, j'ai remarqué plein de nouvelles repousses ! Des petites mèches qui apparaissent partout, certaines encore timides, d'autres déjà assez longues pour me donner une jolie petite frange surprise !
Mon miroir me rappelle chaque jour que la patience et la régularité portent leurs fruits.
Ce Sérum est devenu mon indispensable ! 20 ans a tout essayer pour retrouver mes cheveux de mon adolescence (les maladies hormonales ont détruit mes cheveux) aujourd'hui je retrouve de la densité et j'ai plein de repousse !
It does really work! 1 year, this is how long I have now (Aug 2026) been using the IR Clinical Serum. My hair is fuller, grew back stronger after breastfeeding.
Why investing in fake hair when I can invest in my own and it's cheaper!! Just fantastic!
Estoy encantada con el sérum IR Clinical. Lo empecé a usar porque notaba mi cabello más débil y con más caída de lo normal. Después de varias semanas de uso constante, he notado menos cabello en el cepillo y en la ducha, y mi cuero cabelludo se siente más saludable. Además, tiene una textura ligera, no engrasa el pelo y es muy fácil de aplicar. Para mí, se ha convertido en un imprescindible dentro de mi rutina de cuidado capilar. Lo más importante es ser constante para empezar a ver los resultados.
