I have had one hellacious nightmare of a time following the removal of henna. WAIT! before you continue scrolling thinking that this review isn't applicable to you, READ ON (if you just want the Wella info, scroll towards the last couple paragraphs lol)
SO, after two bleach washes, one full on bleaching, and failing miserably with 2 Wella toners (t18 and t14) My hair basically remained the same shit shade of yellow/orange. The toners not working was my own fault because I hadn't, and couldn't, bleach my hair any lighter.
Okay, so I made the mistake of trying to do my own bayalage, darkening my roots only (which were the most vibrant shade of yellow) and though I wouldn't be outcasted by society by the result, I still didn't like it.
So, I color stripped with dawn dish soap and baking soda and was left with a more even shade of yorange (a hideous marriage between two hideous colors)
SO I went to Sally's and knew a demi would do the trick but opted for Ion since I'd used it before. Well. I don't know which is worse, it coming out too dark (as demi's tend to) or not coming out at all. WHICH IS WHAT HAPPENED. literally, no color deposit. with a 10v.
I was in awe.
So. failing at every step of the way. I went back to Sally's and bought Wella demi's in 9NA and 8N (light ash blonde and neutral light blonde) 4.99 ea but were BOGO at the time, i bought the wella demi developer and left with nothing but hope to keep me going.
I mixed the product, added a couple drops of Ardell Red/Gold corrector (99c per packet at sallys) and applied.
legit, 25 mins later (directions say 20, I wanted to be sure) I rinsed, applied the Ion Color Sealer (4.49/ tube) and my hair was the loveliest shade of light golden brown with hints of strawberry blonde. NO LIE, nearest to my actual hair color (at least what I can remember from like 10 yrs ago). It's perfect. Shiny, and no damage.
The only cons are that you can't use a any 10v developer with their demi shades, you have to buy theirs. the smell of the dye is nothing as pleasant as Ions. the dye is very runny but if you have a tint brush youre okay.
ALL IN ALL:
great buy, sosososo glad I didn't give up and gave Wella a shot. Ion, you suck.
