Keratin is a protein that is a primary ingredient for two different treatments; one is the straightening, smoothing process populated by the Brazilian Blowout, and another is a deep-conditioning treatment that adds proteins into the hair. For the latter, there are keratin treatments specifically formulated to help preserve color and repair damaged hair. You can buy keratin-infused deep treatments to use at home. We recommend Paul Mitchell Awapuhi Wild Ginger Keratin Intensive Treatment, which is this year's Total Beauty Awards Winner. 

Does this answer your question? 

the paul mitchell wild ginger is the bomb.

Cibu International is a brand made by stylists of the Cielo and Bubbles Salons. They have really quirky, Asian-inspired names for their products, and they use bamboo, lotus flower, and white lily. They just released a new line called Hi-Ya! Keratin Reconstructive Treatments. They offer shampoo, conditioner, and a deep conditioner, which I just ordered 2 days ago online and received today. In the online description for the Hi-Ya! line, it says, "Ideal for color and chemically treated hair", which is perfect for my hair because it's been through bleaching and dyeing 3x in 5 months.

If you want to do Keratin treatment with dyed hair, go for the Hi-Ya! line, but that's mostly for fixing damaged hair. If you just wanna maintain it, I suggest Cibu's Geishalicious line. They have a shampoo for it with a Hue-Nu conditioner to pair off with it. There's also a Geishalicious Color Enhancer.

You should check it out now. They have a bunch of promotions going on right now. :)
