Argan Oil Serums and Brassy Hair
Could silicone serums with argan oil stain hair and cause it to take on reddish/brassy tones? I have lots of added highlights and I use an argan serum with a golden color. Many of the argan serums have red and yellow dyes added to them. Could that be the cause or is it all in my head?
I know one popular brand that sells an argan serum has an original version, and a "lighter" version for blondes. I don't notice much of a difference between both ingredient lists.
