I am trying to get a nice red with some light-medium brown tone. Will 6.35/6GRV mixed with 6.64/6RC (equal amounts of each) give me that result? Also note covering 60% white/grey hair.

Hello. Im a licensed cosmetologist. Can i mix Dialight and DiaRichesse?

Asked by: AnyaSD
Hi! No we do not recommend mixing Dia Light with Dia Richesse. DIA Richesse is an alkaline demi-permanent haircolor, and Dia Light is an acidic haircolor therefore, they are not compatible. We hope this is helpful. Thank you for your question.

How is the 9 volume developer you suggest have a different impact than a 10 volume. I am a professional colorist. 

Asked by: Bunny
The Diactivateur 9 volume is formulated to be used with Dia Richesse and Dia Light for optimum results. The 9 Volume mixed with Dia Richesse is used to blend up to 30% white hair. Mixing Dia Richesse with a 10 volume will produce unpredictable results.

If you use a 15 V developer and the hair lifts 1 level, will when the color fades the lift also fade? Or will there be roots showing?

Asked by: Gem01
Hi, DIA Richesse has the ability to lighten up to 1 1/2 levels. The tone can fade but the lift is permanent so the new growth would be darker. We hope this is helpful.
