The Dos and Don’ts of Applying Heat on Dyed Hair

As someone who has dyed their hair for years, I know firsthand the importance of applying heat properly. Whether you’re blow-drying, straightening, or curling your hair, how you apply heat can make or break your look. Here are the dos and don’ts of applying heat on dyed hair.

DO Use a Heat Protectant

Choosing the right heat protectant is essential when it comes to applying heat on dyed hair. A good heat protectant can help prevent split ends, breakage, and damage caused by high temperatures. I recommend choosing a protectant that contains ingredients that nourish and protect hair such as argan oil or keratin. Apply a protective product onto your hair when it’s damp, then comb it through from roots to ends. This will create an even layer of product that will help prevent damage over time.

DON’T Apply Heat Too Often

Heat damage is real, folks. Applying too much heat on dyed hair can cause significant damage to your hair and even change the color of your dye job. To avoid this, try to limit heat styling to just a few times a week. If you’re in a rush, try opting for heat-free hairstyles to keep your dyed hair looking healthy and fresh.

DO Use Low Heat Settings

If you’re going to apply heat on your dyed hair, it’s crucial to use the lowest heat setting possible. High heat can cause significant damage to your hair’s cuticle, leading to split ends and dryness. Instead, use your curling iron, straightener, or hair dryer on its lowest heat setting. It may take a bit longer to style your hair, but it’s worth the extra time to keep your dyed hair looking healthy.

DON’T Use Cheap Heat Tools

Investing in high-quality, professional heat tools can make a significant difference in the health of your dyed hair. Cheap tools often don’t heat evenly, and they can cause significant damage or break your hair. Investing in high-quality tools such as a ceramic curling wand or a professional hair dryer can help protect your dyed hair from damage.

DO Take Regular Breaks

Taking regular breaks from heat styling can do wonders for your dyed hair’s health. Try to choose at least one day in the week when you don’t style your hair with heat. If you can, opt for air drying during the week to keep your hair looking healthy.

DON’T Apply Heat to Wet Hair

Whatever you do, don’t apply heat to wet hair. Putting higher heat on wet hair makes your hair more prone to breakage and damage. Make sure you towel-dry your hair properly and let your hair air-dry and become damp before applying heat on it.


Q: How do I choose the right heat protectant for my dyed hair?
A: Look for ingredients such as argan oil, keratin, or silicones that add a layer of protection to your hair. Avoid ingredients such as sulfates and alcohol that can strip hair of its natural oils, leading to dryness and damage.

Q: Can heat damage change my hair color?
A: Yes, high heat can cause significant damage to your hair cuticle, leading to color loss and dullness.

Q: How often should I apply heat on dyed hair?
A: Try to limit heat styling to only a few times a week. On other days, opt for heat-free hairstyling to keep your dyed hair looking healthy.

Q: Can I use a blow dryer on high heat for faster drying times?
A: It’s not recommended since higher heat can cause significant damage to your hair cuticle. Opt for medium heat settings for a faster drying time without causing damage.

In conclusion, taking care of dyed hair is essential, especially when using heat styling tools. The dos and don’ts of applying heat on dyed hair include using a heat protectant, limiting heat styling, using low heat settings, investing in high-quality heat tools, taking regular breaks, and not applying heat to wet hair. Remember that following these tips can help prevent breakage, dryness, and damage caused by high temperatures.
