Certified real women please respond with how feasible it would be to dye your hair in that style every month, I would imagine that would cause damage. Maybe it's a wig?
If it were demi/semi permanent dye and deposit only (and not bleached beforehand) its not that damaging. Hi-lift and permanent colors start going into more damaging territory, especially if you like changing your color often.
If peroxide developers are needed for any step of the process, there
will be damage.
If I have the timeline wrong forgive me, but I refuse to look at her pages outside of what is posted here already
Assuming this is the starting point, you can already tell the blonde side is fried, if not damn near fried
The two different tones tell me there was some hot roots action (the hair closest to the head processes faster due to body heat). It also looks like there was an attempt to tone, but because of the hot roots, the toner only took to the lighter areas vs. the darker.
Now we go to the next progression
If this were another round of toner in order to get an all-over red, this ultimately failed. If this was done to get a more even canvas for the all over red, it's a choice, but works in the end. When going from a very light blonde back down to a medium/dark tone, you need to "fill" the hair. Imagine a gradient scale, 10 being
light yellow, to 1 being a
deep red, almost brown. This is the scale hair stylists will follow when taking someone to a different level (the number that falls on this scale). Natural hair colors also sit on the same scale, except going from black, to browns, to blondes. The first scale corresponds with how the natural hair will lighten after reaching certain levels. For example, if you are bleaching jet black hair, it will start out as that deep red when lightening.
In the first picture, her roots are easily a level 10, if not 11. This is the lightest you can go before your hair will start melting away. The mids and ends are about an 8, possibly 9, which is still light, but the bane of any woman's existance when trying to go platinum. The red in the first picture is a level 6, not dark, but not light either. The rule of thumb is, you can comfortably go either way up/down to 2 levels before you have to do more intensive processes. If Ellie is starting at a 10, and wants to go down to a 6, that's a 4 level difference. In the areas that are a level 8 however, will work just fine going down to that 6. When you need to go 3 levels or more lower, you need to do a process called "filling". If you don't fill, the color will come out muddy and dull, and in some cases not "stick" and wash out faster. To fill hair, you take a dye that will act as the middle man between the two colors. Usually it's a copper or gold tone depending on what the desired end result is.
Im assuming that based off of the tone, that this was an attempt to fix the skipped "fill" process. The color looks dull, even if you take into account that its not fresh as the red also is looking dull. Some stylists will fill with a neutralizing color (ex: if they are cancelling out yellow tones, a purple toner/dye will he used) for fashion colors (your blues, green, pink, etc) but overall this is a good canvas for the desired end product despite how ugly the color is.
You will only be able to truly tell how well everything was blended after a few weeks of not recoloring it, as the blonde side will come out still when fading if it wasn't a good match. Continuing to refresh the color will help blend it more, but switching to a new lighter color will be a journey. If she wants to preserve hair health, the only option would to be to stay at the same level color, or go darker until everything has grown out and gotten cut out with regular trims.
As a general for hair health, smooth, silky and shiny hair = healthy hair. If the hair feels like straw, breaks extremely easily, and is frizzy, it's not healthy. If the hair is coming out in mushy clumps, looks like cooked Ramen noodles, and takes an extremely long amount of time to dry, it is damaged beyond repair and needs to be cut
