The main cause of hair color appearing progressively darker over repeated applications is in the application of the dye itself. That is, many people make the mistake of coloring their entire head of hair each time they color. Not only do you not need to do this, you don't want to do this, either.
Hair dye does not affect your natural hair color! After you dye/bleach your hair, new hair which grow out will always be your natural color unless some other factors affect that color.
The genes for making melanin might turn on or off over the course of a person's lifetime. If this happens in the cells at the bottom of your hairs, your hair might change color! Different genes control the levels of eumelanin and pheomelanin produced by melanocytes.
If done properly dyeing/bleaching shouldn't affect hair growth long term. Of course, if you did serious damage to your scalp then yes it could have lasting affects on your hair. Ripping your hair out, especially repeatedly, is a bigger cause for concern.
Hair dyeing does not inhibit hair growth, but it may cause hair loss by damaging the hair that is color treated.
You Didn't Lighten Enough Beforehand
"Essentially, if your hair is too dark, the color won't turn out the way you want it to." To get the color you want, start by lightening your strands as much as possible by bleach or patient highlighting them before coloring.

Using products that are designed to nourish the scalp and hair can definitely speed up this process, but on average you'd be looking at six months to a year to fully see a difference in your hair's condition.
How long does permanent hair dye generally last? Permanent hair dye typically lasts for between four to eight weeks before it grows out or fades (more on that below).
You can expect hair loss to continue throughout treatment and up to a few weeks after your last treatment. Hair regrowth typically begins three to six months after your treatment ends. When your hair regrows, it may temporarily be a different shade or texture.
But some children with light hair, including towhead blonds, strawberry blonds, dishwater blonds and redheads, see their hair go dark brown by their 10th birthday. The reason for this change is because the amount of eumelanin in your hair increases as you mature, according to some research.
When hair starts to regrow, it appears like fine “peach fuzz.” It is usually translucent and thinner than the rest of the hair on your scalp. If you recently underwent surgery or had a head injury and are worried about hair growth on the bald spot, the appearance of peach fuzz is a positive sign.
The bottom line: Several factors can change the color and texture of hair throughout your lifetime. They include stress, chemical hair treatments, heat styling, genetics, aging, medical conditions and illness. and pregnancy.
Give it a month to 6 weeks after bleaching and see if your hair starts to recover.
These genes switch on and off at different points in our lives – hence the reason our hair changes color as we get older. Usually, our hair will turn darker because eumelanin production increases as we age (until we go gray, that is).
As a general rule, wait at least four weeks, and preferably six weeks, before starting another treatment. Semi-permanent hair color can be used more frequently than permanent tints if desired. It is designed to fade, which means more frequent treatment is needed.

"If the tone is slightly darker in some areas, you can try to scrub those areas with a clarifying shampoo to lessen the visibility of the different tones," Tang says. If you can eventually achieve that even base, you can re-dye the hair — if your hair is healthy enough, that is.
