Rated 1 out of 5 by from TURNED MY DARK HAIR/ROOTS ORANGE! I’m SO MAD!!! I have always got my hair done in a salon but with Covid happening it has been near impossible. So I took the advice of the manager at Sally’s who told me to use wella mudslide on my dark hair,I even asked if I needed a toner or anything she told me NO! Well I had some grey hairs coming in that are now orange as well as the whole top of my head! I have dark hair naturally and when I started this color followed everything to the letter! I would never tell anyone to use this that has dark hair,now I know why doing this at home is no good.....

Rated 5 out of 5 by from Won't stain your skin I love using this product. In 4 years I switched colors as I aged. The only down side is the price has tripled and having to color my roots every c 3-4 weeks,it has become a lot costly for me.

Rated 5 out of 5 by from Root Beer Float I sent a picture to my hairdresser that I wanted to go as close as possible to my natural color at the root and lighter towards the ends. My natural hair color is dark blond/light ash brown.This color worked great, covered my grey with no problems. The only situation is I had the underneath I had a dark red/cabernet color so that still has a hint of red but everyone knows how hard it is to get rid of red lol. Totally recommend this color.

Rated 2 out of 5 by from Disappointed When I think of iced espresso I think of a dark rich brown not a brown with red tones. Unhappy with the color.

Rated 5 out of 5 by from I love this color but it is not cool This is the perfect color for me. I've been trying to get close to my natural color after years of dying and my hair is naturally a chestnut dark brown. This color is PERFECT! But it is definitely NOT COOL, so don't get this if you're looking for a cool-toned, ashy color.

Hi, i just bought 2 20 developers and 2 different toners, i was just curious if that size developer is the correct one where you mix the whole bottle in with the 1 bottle of toner. Please let me know, thank you! 

Asked by: kendalmarie
Hi, for the color charm wells you mix 1 oz color 2oz developer, I will suggest you buy a measure cup so you get the correct formula., good luck.

Which is lighter, 8bc or 7bc Wella Gel color

Asked by: Susie Q Q
Example:  1 is black and 10 is lightest blond.  Then their are all the numbers in between so 8 would be lighter than 7.

I currently use Wella the color Mudslide. I want to go a little lighter. Should I go 1 color lighter or 2?

Asked by: Melanie04
I use the root beer for my root touch up. It is basically a dish water blond. It looks dark on after about 20 mins but when I rinse it’s the perfect color to match my dirty blonde.

Is this shade a ash brown My clients wants to be a ash gold brown

Asked by: JJprecious
I don't think there is much ash to these two colors.  I find more golden tones to them.

I used Wella 6NW last time for my grey roots and they are more of a red brown now. I have think curly hair and my grey is stubborn. I wanted to try the Wella Gel 6BC Mudslide. Will that lift the warmth and give a natural light brown or it too dark?

Asked by: Lorijax79
You may end up with some warmth still. Ive used 6BC before and 5 BC and they appeared warm to me but in your case may cancel some of that red. 6NW is more of a golden blonde color so I'm curious as to why it appeared red brown on you. Are you 100% grey or do you still have some color left?

What developer 20 or 40 would you reccomend using for complete gray coverage and to reduce red pulling through?

Asked by: mary1971hendricks
The higher the volume developer the higher the lift and more damage it causes. When you lift hair that’s when warmth pulls through, my recommendation for deposit only and no lift would be a 10 Vol or 20 Vol developer. becareful on the roots because heat from the scalp can make the color turn lighter! hope this helps~
