If you're wondering, “How long does permanent hair dye last?” the answer is simple. If you've had a permanent hair dye, in a salon or at home, whether a full head, lowlights or highlights, the colour will essentially last until your hair grows out or you decide to re-colour it.
After you've tinted your hair, you need to let it grow. Remember to treat it like colored hair: just because it's your natural color doesn't mean it isn't chemically treated. Hair usually grows roughly one-half-inch per month. If you keep your hair long, it will likely take years before it is truly "natural" again.
Changes to the inner and outer structure of the hair shaft can damage hair, making it fragile and prone to breakage, which could eventually result in thinning hair or hair loss in areas. Hair dyes can weaken hair, but people can take precautions to minimize potential damage if they still choose to dye their hair.
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.
There's no hard-and-fast rule about when (or if!) you should stop coloring your hair and go gray; it's ultimately a personal choice.
Darker hair is better at camouflaging damage— If your hair needs some TLC, going dark is a smart option. Darker color molecules naturally weigh down flyaways and seal split ends much better than blonde bleach, making hair look thicker and shinier.
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.
Our best overall pick is Biolage Haircolor, a henna dye that's free from harmful chemicals including ammonia and PPD.

The general rule of thumb is once every 4-8 weeks, give or take. This frequency varies from person to person, depending on factors like the type of hair dye used, the specific color used, your hair regrowth rate, and any additional treatments you may tack on (like chemical straightening or perms).
Grow Out Your Hair
It may seem obvious, but another way to get back to your natural hair color is by growing your hair out. It can be a useful and low-maintenance strategy if you do it right and it can save your hair from a lot of damage.
Over time with repeated coloring sessions, the structure of your hair changes. It will become weaker and more prone to breakage. The more damage your hair incurs, the less color it will hold. That's why it's so important to prioritize repair if you color your hair.
Start by parting the back of your hair down the center. Then, cover up any dyed sections of hair so that you're able to focus on evaluating your scalp. Have a friend match the color against our color chart to figure out the color closest to your own. For best results, make sure you're in bright, natural lighting.
The chemical components in the dye damage the protein within the hair shaft to weaken it, as well as snap locks, particularly those in the telogen stage of the hair cycle. Ultimately, every time you colour your hair, there is an increased risk of hair loss.
Box dyes are progressive hair dyes, meaning they build up on the hair shaft over time. This means that with each use of a box dye, the color continues to deposit onto the hair strand, which can cause brittleness, damage and breakage.
Over time, and with repeated colouring sessions, these changes in the structure of your hair will leave it weaker and more prone to breakage. The more hair is dye damaged, the less the colour holds. That's why it's so important to prioritise repair if you colour your hair.
Guéguen cites previous research which found over 80 percent of those surveyed express a dislike for people with red hair.
What are the most difficult hair colors to maintain? Red hair is notoriously difficult when it comes to upkeep. While it's the hardest color to fully strip from your hair, it's also the first to fade, often lightening drastically within the first few washes.
Just as with blonde hair, red hair requires a little extra tender love and care. Hack admits that red hair is his favorite to color, but that she's noticed many women don't realize the extent of after-care that's needed. “Red is the hardest color to keep lustrous and the hardest color to remove,” she adds.
First, there are obvious risks. Using a sharp razor means that you could cut yourself. Then there's the regrowth stage: Shaved hair grows back after a couple of days, and when it does it can be prickly or itchy. This can leave you feeling uncomfortable.
Hair follicles typically grow back within one to two months as long as your scalp does not need to recover from damage. If your hair follicles are damaged, it can take up to four years until they are able to regrow hair normally unless it is permanent, in which case no new strands will grow.
Virgin Hair refers to the hair which is 100% RAW Natural or UNPROCESSED human hair coming from real donors. In other terms, the virgin hair is the hair which is never been chemically treated, permed, colored, dyed, bleached, processed or styled.
People with brunette hair are the most attractive.
By presenting pictures of the same woman with different dye hair colors, the researchers found that out of the population analyzed, 67 percent of men preferred the woman with brunette hair and 71 percent of women chose the man with brunette hair.
Most Attractive Hair Colour According to Men
According to the survey, the majority of men (42%) found blonde hair to be the most attractive. This was followed by brunette (36%), red (16%), black (5%), and gray (1%).
According to the study, men and women both viewed people with brunette hair color as more attractive than those with any other hue.
Common ingredients in hair dye products include ammonia and hydrogen peroxide, which is a bleaching agent. Both chemicals can loosen hair in the telogen phase. Hair coloration products can also weaken your hair shafts, leading to breakage.
