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 must understand that it will take some patience during the transition," says Kandasamy. "You will have to grow your roots at least one to two inches. That means you will have to wait anywhere from two to four months to allow your hair to grow an inch or two. (If you can, wait even longer)."
If I dye my hair blue, will it still grow back in its natural color (black)? Yes, your hair will always grow out from your scalp in the same naturally produced color. Dyes only affect the parts of the hair that are exposed at the time the hair is dyed.
Does permanent hair dye fade? Sadly, yes. While permanent hair dye won't wash out of your hair in the same way that temporary, or semi-permanent hair dye does, it will eventually start to fade and change shade over time.
Give it a month to 6 weeks after bleaching and see if your hair starts to recover.
Unfortunately, hair Color damages your hair. When you dye your hair it lifts the cuticle, altering the hair in a way that will never completely revert back to it's natural virgin state. However, the hair that grows from your scalp will grow out normally so only the hair that has been dyed is affected.
The hotter the water and the more often, the faster your color will fade. Instead, wash in warm water and rinse in cold. The cold water will actually seal the cuticle and leave your hair looking extra glossy. The ultraviolet rays in sunlight break down the chemical bonds in your hair, making the color fade.
Stripping hair color with a professional
If you're looking to get rid of hair color, the safest way is to contact a professional at a salon. A colorist may use bleach or sulfur-based hair stripping products to lighten your hair back so that it can be re-dyed.
Once you have processed or color-treated hair, it can never go back to being virgin. That's right, once you've dyed your hair, even just once, you lose your virgin strands forever. Virgin hair is a hair colorist's dream because it's also much easier to color hair that doesn't already have dye on it.
2. And your hair might feel healthier. While hair dyes and techniques have come a long way since their follicle-frying beginnings, they do still leave some damage. Taking a hiatus from color will help your hair return to its previous state--especially as dyed ends get chopped off.
Dark colors such as brown and black take longer to fade. It's because these dark hair dyes are composed of small molecules that penetrate the hair deeply.
Permanent hair dyes have much more staying power than semi-permanent hair dye or temporary hair dyes, but they still fade a bit with every wash. The good thing about permanent hair dye, though, is that it will stay vibrant up until that 8-week mark in most cases.
Altering the hair's protein structure through permanent and demipermanent dyeing can cause side effects that include: loss of hair strength. less ability for your hair to handle heat styling. reduced hair thickness.
How long does it take for your hair to fully transition? It will take roughly 8-12 months if you just let your hair grow. If you want to transition by growing your hair out, you'll see and feel your natural hair coming in over the first 1-3 months.
Under normal conditions, the World Trichology Society reports that hair grows about a half-inch (1.2cm) per month. This means that you could grow about 6 inches (15.24cm) of hair per year. But this varies from person to person, with some people naturally growing hair more quickly and others more slowly.
There are basically 3 main ways to transition to naturally gray hair: to let it grow as it is and be patient (a.k.a the “cold turkey” method), to cut your hair very short and regrow it fully gray, or ask your hair colorist to blend your grays with the dyed hair color.
Your hair may look thinner
So when you stop coloring your hair may have a noticeable loss of actual volume and the appearance of it.
Typically, white people start going gray in their mid-30s, Asians in their late 30s, and Blacks in their mid-40s. Half of all people have a significant amount of gray hair by the time they turn 50.
