      Use rhubarb powder to have beautiful and glowing hair with unique highlights!



      Rhubarb has a high dyeing capacity

      on blond and light brown hair, so it’s rarely used 100% pure and it is often used mixed with other herbal hair colors.

      Irrespective of your chosen mix, you have to apply it on your hair only AFTER having done a test on a hidden strand of hair.

      Rhubarb dyes your gray hair by making it yellow, and if mixed with other herbal hair colors, it can help obtain various shades of blonde. It can also revitalize streaks and highlights.

      But Rhubarb is a highlighting herb, so, even if it has a strong dyeing property, it is NOT a permanent herbal hair color, like Lawsonia (red henna). So, as opposed to Lawsonia, it doesn’t dye your hair permanently: the color lasts, but it will tone down little by little with every wash. How long it stays on your hair depends on your hair porosity.

      If you want to use it 100% pure on your hair, it can result difficult to apply hence we suggest you to use flaxseeds gel instead of water:

      To optimize the coverage and the color duration on gray hair, it can be mixed with a low quantity of Lawsonia that can be decided based on the shade you want to obtain.

      To dilute its high dyeing power, you can always mix it with Cassia or Sidr.

      You can create your own unique herbal hair colors mix to obtain new, glowing hair colors with natural unique highlights with every new application.

        Use rhubarb powder to have beautiful and glowing hair with unique highlights!

        Il rabarbaro 

        è l'erba riflessante naturale perfetta per regalare dei riflessi caldi, dorati ai tuoi capelli naturalmente chiari. E' l'alternativa sicura e sana per colorare in modo delicato i tuoi capelli (bianchi inclusi).

        Il rabarbaro è indicato per ottenere varie tonalità di biondo sui capelli chiari (biondi e/o castano chiaro). Il rabarbaro può essere miscelato con altre erbe tintorie, anzi raccomandiamo un suo utilizzo assieme ad altre erbe tintorie per raggiungere la tonalità desiderata in base alle proprie esigenze.  

        Il rabarbaro è un'erba riflessante che riesce a coprire i capelli bianchi 

        colorandoli di un caldo colore giallo dai riflessi dorati. La tonalità raggiunta può essere smorzata o intensificata fino a raggiungere un biondo veneziano semplicemente aggiungendo della cassia, sidr, amla o lawsonia nel tuo mix ottenendo una tonalità più o meno vivace in base alla percentuale di erbe tintorie che usi nel tuo mix.

        Cosa ci differenzia? La qualità!

        Il nostro rabarbaro è 100% puro, della migliore qualità che esiste sul mercato assicurando la massima capacità riflessante sui tuoi capelli! 

        A differenza delle tinte chimiche che modificano irrimediabilmente la struttura dei capelli penetrandone il fusto e rendendoli ruvidi e opachi, il pigmento riflessante del rabarbaro unito ai pigmenti coloranti delle altre erbe tintorie ti permette di creare un colore esclusivamente tuo, dai riflessi unici ed eccezionali.  

        Erba riflessante 100% pura, dalla massima capacità riflessante donna ai capelli delle sfumature dorate uniche e naturali. In più lascia i capelli rinforzati, voluminosi e  lucenti e purifica il cuoio capelluto. Applicazione facile e veloce per un colore unico dal risultato professionale!

        Come tutte le altre erbe tintorie, anche il rabarbaro si prende cura del tuo cuoio capelluto mentre riflessa e colora i tuoi capelli chiari.  

        Il rabarbaro ha proprietà antifungine e antibatteriche che:

        sanificano e purificano la cute

        ripristinano il pH del cuoio capelluto

        promuovono la crescita dei capelli. 

        Il Rabarbaro, più di una tinta naturale per capelli biondi e chiari!

        Più di una semplice tinta naturale per capelli: un vero e proprio trattamento di bellezza non solo se hai i capelli fini e sottili ma anche se hai i capelli grassi. Un utilizzo costante aiuta a lungo andare a contrastare l'impoverimento del fusto e l'indebolimento della chioma.

        Rinforza, ripara e colora i tuoi capelli!

        Il rabarbaro: 

        svolge anche una potente azione sebo-equilibrante e antiforfora

        rende i capelli voluminosi, forti e lucidi. 

        Usa il Rabarbaro per ottenere una bella e raggiante chioma dai riflessi unici!
