When you mix hair dye, the clock starts ticking. You have about 45 minutes before the dye degrades and becomes unusable. After that, it’s a waste of time and money to use it.
But what if you’re not ready to use it right away? Can you save mixed hair dye for later?
5 Don’ts after hair color
Hair dye can last for quite a while after being mixed together. However, it is always best to use it as soon as possible for the best results. If you do need to store it, make sure to keep it in a cool, dark place and use it within six months.
Can You Use Mixed Hair Dye the Next Day
Most hair dyes will recommend that you wait at least 24 hours before shampooing your hair after dyeing it. This gives the color time to set and prevents it from washing out too quickly. However, some dyes can be used immediately after they are applied.
If you are using a semi-permanent or temporary hair dye, it is generally safe to shampoo your hair right away. These types of dyes do not penetrate the hair shaft as deeply as permanent dyes, so they are less likely to cause irritation if they are not left on for the recommended amount of time.
If you are using a permanent hair dye, it is best to wait at least 24 hours before shampooing your hair.
Permanent dyes contain chemicals that can cause irritation if they are not given enough time to set in the hair. In some cases, waiting 48 hours may be necessary to avoid any discomfort.
