How soon can you dye your hair again? You should wait at least two weeks after your last dye session to re-dye your hair, regardless of the reason. If you're maintaining your color, stylists recommend returning to the salon every four to six weeks for a touch-up.
For normal-to-dry hair, that window can stretch up to three days between washing your hair and applying at-home dye. One notable exception is if you're using a temporary, wash-out hair dye. It's typically best to apply these to freshly-washed hair, since they'll only last until your next shampoo session.
Reusing leftover hair dye after two days can be risky for a few reasons: Chemical Stability: Many hair dyes contain chemicals that can degrade over time, especially once they have been mixed. The potency and effectiveness of the dye may decrease, leading to uneven color or poor results.
If you had a bad coloring job your best bet is to visit a reputable beauty salon and have a trained professional perform corrective coloring that will rid you of the unnatural color and give your hair a second chance.
Don't Wash Your Hair (At First)
Izquierdo says to wait three days. “This gives time for the cuticle to close and the color to set,” he says. That's why you might want to skip a workout or two so you don't have to wet it or wash it—if you do, you're lifting the color right out of your hair.
If your hair is healthy, meaning it's not fragile and damaged, technically, you can dye it when wet. However, we recommend coloring hair when dry so you achieve a look that aligns with your desired results.
You Missed a Spot
For a more permanent solution, try applying the hair dye to the exact area you missed before. Make sure to position a mirror in the right spot so you can see it clearly. Or, turn to a professional hair colorist who will be able to seamlessly fill in any gaps in your hair color without overlap.
As mentioned, your hair type can play a role, too. Those with oily hair may only need to wait one day between their last shampoo and next dye job. People with dry hair, meanwhile, may need 2-3 days in between to allow enough oil to build up.
Jumping into another dye job too soon could worsen the situation. Typically, it's advised to wait a couple of weeks before scheduling another dye session. This waiting period helps prevent over processing, which can severely damage your hair and even alter its texture.
Certain harsh chemicals in popular box dyes have given many stylists pause. Common concerns include: Ammonia - This mixing agent lifts cuticles to deposit colour but is quite drying over time. Peroxide - High volumes like 30+ developer cause more damage to delicate hair.
Generally speaking though, it's best to wait 4-6 weeks before having another color treatment – in most cases, this is enough anyway and reduces the risk of hair damage. There are some exceptions, but in general, it's better to err on the side of caution and wait for this long.
Important Guidelines. Always wait one week and one shampoo after a relaxer service before applying permanent hair color. This ensures that there is no scalp sensitivity or discomfort for the client. Evaluate the porosity and elasticity of the hair.
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.
Daily washes with hot water and a clarifying shampoo (not a color-safe shampoo) will go a long way toward washing out your color. Until your hair is ready for another attempt at dyeing, you can use a cool-toned gloss to tide you over with short-term hair color correction while also adding gorgeous shine.
Some possible fixes include re-dying the hair (either the same colour or darker), nourishing your hair to improve the condition, using toner to touch up the patches, or using gloss treatments.
Bleeding the color out is the optimal solution providing that you have the right product on hand. A regular or clarifying shampoo would be the best product in this situation, and ideally, you should keep washing it until enough dark dye has bled out of your hair that you're happy with the resulting hue.
Don't shampoo immediately before dyeing your hair. Why? Because 1-2 days unwashed hair has a protective barrier on the scalp - it means there's less chance of any irritation and color pigment is better deposited. Also, just before dyeing, avoid using styling products (dry shampoo, hair spray, gels etc.).
Keep it cool
To keep your new hair colour vivid and bright, we recommend washing your hair with cold water (as cold as is bearable). Cold water keeps the hair cuticles closed and therefore stops the colour running out and fading too soon. Warm water is the enemy!
Post-color washing is essential for maintaining the structural integrity of your hair. By cleansing and conditioning, salons help in closing the hair cuticles, locking in moisture, and preserving the smoothness of your locks.
No. It's best to avoid washing at least 24 hours before dyeing. However, if your hair is really dirty, has a lot of product in it, or you need to shampoo for a special occasion, you can do that – as long as it's a one-off, you shouldn't see any long-term negative effects.
While most hair color tips recommend dyeing your hair when it's dirty, salon pros say there's no real difference in the results.
