I thought I would share my thoughts on this fabulous product.
For ladies like myself with over processed hair from bleaching/frying your hair to the point you fear to use a permanent or even demi dye mixed with developer because you know more breakage will happen lol.
Ion's color masque is perfect for that. You can mix the colors to create other colors. It can be a bit tricky. I tried putting some on paper to see what color I have created, it doesn't show the color on paper to how it will turn out on your hair. I don't mind so much because I love experimenting and can live whatever color I have for a couple of weeks.
Right now I have brown hair. My regrowth is dyed 5a with a pernament dye because my natural hair color is a very ginger red. As for my midshafts to ends, I won't ever dare attempt putting any developer with dye on them, I have a lot of breakage because I used to be platinum/whitey blonde. My midshaft to ends do not hold color well at all.
I have been using Dark Warm Brown color masque and it evens out my hair. I am shocked how well the color masque colors your hair.
Now for me it does stain the hair, it doesn't 100% wash out but I assuming it's because of how severely bleached and overly processed my ends are. I have never had success with it covering up my natural hair/regrowth. Although my natural regrowth is ginger red, I do know ginger is hard to cover up hence why I use 5a permanent dye.
Even though the masque stains the hair, it does wash out to a very faded color, it's not a bad stain say like Manic Panic kind of stain. It does fade to a very very light shade. Almost back to blonde but with a tinge of whatever color masque I used. I can't complain about that, it's so easy to cover up with the next masque.
I have used all the browns by Ion's color masque.
Even though Dark Warm Brown is very warm compared to their other browns, I wouldn't say it has a warmth base, the base is still very green and at one point because my ends were so light to begin with, when the brown faded, it looked like I had very light brown with a green tinge. Didn't bother me because the next time I used these products, I mixed a bit of the hot red with the warm brown but beware the hot red is strong lol. Yes it does stain green and your bathroom. Bleach did the trick to get it off the tub. I just scrubbed with soap on my face to get the stains off my skin. It took me a couple of tries to figure out a good cocktail to create the perfect brown that didn't fade with a green tone. You need literally a pea size drop of red, it's very over powering. The first time I used a whole tube of dark warm brown with about a teaspoon of hot red thinking it would do the trick. My hair came out a nice dark burgundy color, I did love it and it did fade very well. Just warning people if you do decide to mix it to warm up the brown or the other browns, a little goes a long way.
I live by these color masques. It saved my hair. I can be whatever color with no damage now. I like how I can mix it because my midshafts to ends fade so much, one month I can be a red head, next brown or even burgundy.
I just wish they would sell the exact same product but in a bigger bottle at a reasonable price. And would love to see more colors. My mother would love to see one for black hair with a green base.
