Super pigmentato tempi di posa brevissimi non brucia
Eccezionale. Non mi ha bruciato la cute il colore è INCREDIBILE gia dopo la prima volta ed ho i capelli neri. Tempo di posa 30 minuti risultano mai visto in vita mia. Vale i soldi che spendi

New favorite
Covers greys. Professional quality. Color runs some for the first few washes but doesn’t turn your scalp into a Smurf.

Seriously don’t buy this
Lord, where do I start? There’s no conditioner in the pack for after you’ve dyed your hair. This stuff dyed everything BUT my hair. I took preventative measures but still had parts of my neck, my ears and face dyed. But my hair? Same colour as before I dyed it. Save your money.

PARFAIT!!!
ENNFFFINNN..... Merci j'ai ENFIN trouvé la couleur qui me plaît !!! Un noir intense avec un beau reflet bleu dans mes cheveux (se voit parfaitement AU SOLEIL) et sont bien renourris (suite à ma grossesse) . Le soin post couleur est bien présent il est déjà ds le produit. La seule chose que je pourrais reprocher c'est de ne pas pouvoir m'abonner au produit pour un envoi régulier.

Great coverage and true color
I used Black Saphire. My hair was only colored with a non permanent pink and purple which only took at the ends. So basically I had medium brown with magenta ends. I wasn't sure how this would turn out. I've never done such a dark color. I usually lean blonde or red. But I love this. This colored very evenly. I was also worried it would be more blue than black but I was pleasantly suprised that I got exactly what I wanted...a black with navy blue hue in the light. I can't geek you how long it will last as I only wash my hair about every 10 days. So for me it will last forever lol. I will definitely buy again as I'll keep this color for a long time since I love it so much. I wish I world have tried this years ago lol
