Gray magic and ash blonde (color, product, tone, light)

[mrsmax]

My hair is colored Light Beige Blonde but it's been turning a litle too yellow. I switched to it from Light Ash Blonde because I didn't like the green tones I sometimes got. I have some resistant grays and I've been reading about Gray Magic but wonder if it will bring out red tones, which I really don't want. Can anyone who's used this product give me advice? I generally use L'Oreal Excellence permanent color

I have used Grey Magic. It never gave me red tones.

To cancel some of the yellow in your hair you will need a color with a blue base. I would try mixing the one you use (Beige BLd) with another color in the ash family. Maybe you could use a neutral color with a little ash mixed in...

Or you can use a bluing shampoo.
