"After you dye your hair, don't wash it for at least two days because the hair is still sensitive and therefore will be more like to fade faster," says Sergio Pattirane, a hairstylist at Rob Peetoom in New York City. "We recommend waiting to wash it so that the color stay fresh and longer."

"It takes up to three days for the cuticle layer to fully close, which traps the color molecule, allowing for longer lasting hair color."
Myth 4: It's OK to Wash Your Hair Right After a Color Treatment. Truth: You should wait at least a full 72 hours before washing your hair after coloring. Why? That's how long it takes for the hair cuticles to fully close, which traps in the color.
You must wait at least four days to try and re-color it with permanent hair color. Before actually re-coloring your hair you can try using a color shampoo or color mouse. Or, you can try a temporary repair with half-permanent hair color. You can stain your hair again within a day with semi-permanent color.
Wait At Least 2 Weeks to Re-Dye
Trichologists (hair scientists) recommend waiting at least 2 weeks – but technically 15 days – before you re-dye your hair if it's already damaged. This is especially true if you've used permanent hair color or a high-volume developer (30 or 40 volume).
Dyeing your hair again the same day can cause significant damage to your hair and also your scalp. Typically, you should wait 6-8 weeks to dye your hair again after the first time. Hair dye has a lot of harsh chemicals in them that are applied to your hair and scalp.

After a highlight or balayage appointment, it's good to wait between 48 and 72 hours before washing your hair.
Generally, it's best to wait four to seven weeks before re-dyeing your hair so that you don't damage it, but you can try to dye it earlier if you really hate your current dye-job. If you're re-dyeing just to have a change, wait at least four weeks to apply the new color.
Generally, it's safe to re-dye every 6 to 8 weeks. Permanent hair dye lightens the hair and deposits color.
You can dye your hair while it's wet, but the color might be less vibrant, it might not last as long, and it might be a little more uneven than it would be if you colored it while it was dry.
However, your hair is at its most fragile state when wet, so if not done properly the coloring process could result in breakage and damaged hair. Since most at-home hair color kits aren't meant to be used on wet hair, it's best to leave wet hair coloring to the pros.
While hair color can be applied to wet or dry hair, applying to wet hair does have a couple perks worth making note of: A little bit of dye goes a long way: The added water moisture helps the color to distribute itself evenly.
A common reason behind fast-fading hair color is insufficient processing time, meaning the hair color did not stay on long enough. This especially holds true if you or your client have grey hair. Grey hair cuticles are tightly packed down and take longer to open and absorb artificial hair color molecules.
Does coloring or bleaching your hair damage it forever — like, forever forever? 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.
Most semi-permanent dyes will last between 4-6 weeks, while certain pigments, like blues and greens, may last even longer (this is due to their molecular size and other fun science stuff!). The color will start to fade little by little with each wash, but the beautiful fade out process is all part of the fun!
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.
