Here's The Right Way To Take Care Of Your Red Hair
If you've just dyed your hair red or had a professional do the job, Matrix deems it essential that you wait at least 48 hours before you wash your hair. Waiting to shampoo your newly red hair gives the dye time to set and your hair follicles time to absorb the color.
When you do shampoo your hair, use cooler water. If you wash your hair in the shower, it might not be the steaming hot water your body is used to, but lukewarm water will go a long way in ensuring your shiny red hair doesn't fade.
In fact, laying low on the heat helps red hair as a whole. This means styling tools that use thermal heat should be set to a lower setting. These styling tools include hair dryers, curling irons, and flat irons. You should also stay out of the sun, or start wearing a hat to prevent the dreaded fade caused by UV light.
L'Oréal advises you to take it a step further and not use any heated styling tools at all. Instead of a hair dryer, you can braid your damp hair and let it air dry. This will give the hair a wavy mermaid look .
