"Très bon produit mes ongles sont plus beau et moins cassant"
— Beatrice M. (5/5)
"Ich nehme es seit einem Monat und bin bis jetzt sehr zufrieden. Meine Nägel sind seit eh und je eine Katastrophe (Splittern und sehr weich und dünn). Schon nach kurzer Einnahme haben sie aufgehört zu splittern. Ich bin gespannt, ob sie nach der dreimonatigen Kur stärker und schöner werden."
— Angelika T. (5/5)
"Pour le moment l'action sur la pousse est réellement visible : les ongles poussent bien plus vite. Je ne peux pas encore dire ce qu'il en est pour la solidité de l'ongle, il faut patienter encore un peu. Mais en tout cas les ongles poussent bien plus vite."
— Sophie K. (5/5)
"Ongles très dédoublés, perte de cheveux. Après 1 mois de cure, (j'entame le 2ème mois). Evolution très positive, fini la chute de cheveux et mes ongles ne sont plus du tout dédoublés. Ce complément fait vraiment une très belle différence ! Merci la team :)"

"J'ai commencé la cure depuis un mois et j'en suis très satisfaite ! Mes ongles sont vraiment renforcées et je peux maintenant profiter de les avoir longues (je ne pouvais pas avant, elles étaient trop fragiles et se cassaient). C'est un très bon complément à l'huile verte et au masque SOS. Je recommande !"
— Justine D. (5/5)
"J'ai acheté la cure 3 mois, car mes ongles fragiles de nature, n'arrivaient plus a pousser tant ils étaient fins. . . résultats constatés dès le 2eme flacon : ongles plus longs, plus forts qui ne se dédoublent plus et qui sont vraiment beaux. C'est la 1ere fois qu'un complément marche sur mes ongles !"
