Once dyed, your *dyed* hair will not return to its original color, if the dye is permanent. But the new hair that grows out will always be your natural color.
If you choose to use a hair color remover, be sure to follow the instructions included with the product and keep in mind that your color may not completely return to its original hue immediately. You may be left with a slight tint, but you'll be that much closer to having your natural hair color back.
In short, the general consensus among the celebrity hair colorists I consulted with is that, yes, dying and bleaching your hair permanently alters the integrity of your hair. You're using powerful chemicals to change the makeup of it, after all, and there's not necessarily a magic reversal wand you can wave to undo it.
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.
Baking Soda Paste
Baking soda can be an effective way to remove permanent hair dye naturally because of its lightening properties. Try mixing baking soda with lemon juice, which is acidic, to create a paste. Then, work the paste through your hair, allow it to sit for five minutes, and rinse thoroughly.
Standard time in between appointments is 4-6 weeks, since your hair grows on average 1/2” a month. Of course you can stretch this out to 6-8 weeks if you don't mind the roots. Being able to stretch it out usually depends on what your natural hair color looks like compared to your artificially “sweetened” hair color.
When you wash your hair, dye molecules simply dissolve and your new colour rinses away. Of all hair dye colours, red usually dissolves the easiest in water. As a result, this colour usually fades the quickest.
When it comes to the hair colors that fade the fastest, red might just take the top spot. Per AnswersToAll, intense red shades are likely to fade pretty fast in comparison to auburn and more red-brown shades. This is because brown is the hair dye color with the most staying power of them all.
Your Hair Won't Actually Fall Out
"Hair loss can occur for many reasons, but it's unlikely to be caused by routine hair coloring. Hair color can, though, cause hair damage which can lead to breakage," George says. "This is because the strength of hair is mostly due to strong disulfide bonds in the hair.
After the dyeing process, the cuticle layer must be adequately sealed to retain the hair color. If the cuticle is not closed, the color will begin to bleed even when exposed to minimal moisture.
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.
The most important thing you can do is wait two weeks before using the color again to avoid irreversible damage to your hair. Remember, you could always try to wash your shampoo a few times, if you used a semi-permanent color that didn't look that great, so that it fades and becomes lighter.
Wait At Least 2 Weeks to Re-Dye
After the 2 weeks is up, you can safely re-dye your hair with demi-permanent dye. If you need to use a semi-permanent or permanent dye, it's a good idea to wait a little longer than 2 weeks since those dyes cause more damage to your hair.
Hair can stop growing or grow slowly for a variety of reasons including age, genetics, hormones, or stress. You may notice your hair stops growing in one spot or seems to be growing slowly on one side. There are plenty of treatment options for slow-growing hair, including: medication.
Really? Apparently, Coca-Cola contains phosphoric acid, a very low pH. So when you apply it to your hair, the cuticle tightens, which makes your strands look smoother and your curls look more defined. Others say the sugar adds build-up to your hair, making it look fuller.
What Does Damaged Hair Look Like? Damaged hair has a brittle, straw-like appearance. The hair shaft is fragile and prone to breakage, resulting in split ends and stray, unruly hairs. It will feel stiff and “crunch” upon touch with little movement.
You cannot just easily color over a previous color without having problems occur. However, it's much easier to color from a lighter color to a darker one. Say if you have light brown hair and you want to go to a dark brown. That situation would actually not cause much problem.
Wait at least two weeks before applying another color.
Applying dye again too soon after coloring your hair can cause extensive damage and breakage. Additionally, you will have no way to predict how the color will look, since you're dyeing over an existing dye-job.
How long should you wait before re-coloring your hair? It's generally suggested to wait at least four weeks between coloring hair. That's the minimum interval if you care about your hair but it would actually be better to wait somewhere around six or seven weeks if you're really scared of doing any damage.
Grey hair is healthier than artificially colored hair, easier to manage, and not to mention more affordable (for more tips on how to manage your hair see "Hair's Dirty (Half) Dozen").
Semi-permanent hair colors are less damaging to hair because they are free of ammonia and peroxide. Also called hair gloss, they may bring shine and change the tone of your hair.
Shampooing the day after you dye your hair.
"After having your hair colored, wait a full 72 hours before shampooing," says Eva Scrivo, a hairstylist in New York City. "It takes up to three days for the cuticle layer to fully close, which traps the color molecule, allowing for longer lasting hair color."
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. The colour you go for will also influence how long your hair will stay vibrant.
