FAQ

Frequently Asked Questions

Everything you need to know before you start.

Will this make my hair purple?

No. When used as directed, the violet pigments help neutralize yellow tones without depositing a permanent purple tint.

How often should I use the Purple Duo?

Most users achieve the best results using it 1–3 times per week, depending on their level of brassiness.

Is this suitable for bleached or highlighted hair?

Yes. The Purple Duo is ideal for blonde, highlighted, silver, gray, and color-treated hair.

Will it dry out my hair?

Unlike many toning products, this system combines violet pigments with moisturizing ingredients to help maintain softness and hydration.

Can I use it every wash day?

You can, but most users prefer alternating with a regular moisturizing shampoo depending on their toning needs.

BEST Purple Shampoo

Wonderful products. I transitioned to silver hair from box-dyed dark brown hair this past year. I had the color bleached/matched this past August, which caused lots of yellowing and dryness. I have tried numerous purple shampoos, all recommended. Learned about these on YouTube. These products have been so gentle and amazing, and I couldn't be more pleased with my silver color now. They smell fantastic and leave my hair in the best condition. I have recommended to friends on FB and others with silver hair.

I have used so many purple shampoo lines, but nothing comes close to Kerotin’s! Just one wash and my hair was, as blonde as the first day of coloring it! It’s shiny, soft and smells amazing. Anyone who needs to brighten up their hair...you can’t go wrong with the purple line of hair care products. Mask is a savior!
