This is a great question and one that I get all the time! The answer really depends on how well you take care of your dyed hair and the type of dye used. Generally, most dyes will last around 6-8 weeks before needing to be redone. If you use a higher quality dye and take good care of your hair, it can last even longer! Here are some tips for making your dyed hair last:
-Wash your hair with cold water instead of hot. Hot water can strip away color faster.
-Use a shampoo and conditioner made for colored hair. These products help to protect the color and keep it looking vibrant.
-Avoid using heat styling tools as much as possible. If you must use them, make sure to use a heat protectant spray first.
-Be careful when swimming in chlorinated pools or salt water. Both of these can cause color fading. Rinse your hair with clean water after swimming to remove any chemicals that may be present.
By following these tips, you can help your dyed hair look great for weeks to come!
