How Heat Styling Affects Colored and Lightened Hair

Alright y’all, we need to talk about those flat irons and curling irons because some of you are trying to cook your hair. 😂🔥

I hear this all the time behind the chair:

“Randi, I don’t understand why my ends keep breaking.”

Then I ask what temperature the flat iron is set on.

450 degrees.

Girl. 😭😂

Just because your flat iron can reach 450 degrees does not mean your hair needs that much heat, especially if it is colored, highlighted or lightened.

Chemical services and heat styling can both affect the condition of your hair. That does not mean professionally lightened hair is automatically damaged, but it does mean we need to be mindful of how we care for it at home.

Why Is Lightened Hair More Sensitive to Heat?

Lightener removes natural pigment from the hair through a chemical process. Depending on the starting color, desired result and number of previous services, the hair may become more porous or fragile.

When already-lightened hair is repeatedly exposed to excessive heat, it may have a harder time maintaining its strength, moisture and elasticity.

The effects can become especially noticeable on the ends because they are the oldest part of the hair and have experienced the most:

  • Chemical services
  • Shampooing
  • Brushing
  • Heat styling
  • Sun exposure
  • Environmental stress
  • Friction from clothing and pillows

The lighter and more chemically processed your hair is, the more carefully you may need to manage heat.

Can Heat Styling Cause Hair Breakage?

Repeated exposure to excessive heat can weaken hair and contribute to breakage.

You may begin noticing:

  • Short broken pieces
  • Thin or see-through ends
  • Split ends
  • Increased tangling
  • Rough or brittle texture
  • Hair that appears to stop growing
  • Breakage around the face and hairline

Your hair may be growing normally from your scalp while breaking at the ends faster than you can retain the length.

This is one reason someone may feel as though her hair never grows past a certain point. The issue may not be the growth itself. It may be the amount of length being lost through breakage.

Does Heat Make Hair Color Fade Faster?

Frequent high-heat styling can contribute to premature fading and unwanted changes in tone.

This may be especially noticeable with:

  • Toners and glosses
  • Red hair
  • Copper hair
  • Fashion colors
  • Brunette color
  • Cool-toned blondes
  • Silver and gray hair

If your toner seems to disappear quickly, we need to look at your complete home routine. Shampoo frequency, water temperature, product choices, sun exposure and hot-tool use may all affect how long your color looks fresh.

You invested time and money into your color. Using extreme heat every morning can work against that investment.

Can Heat Make Colored Hair Feel Drier?

Colored and lightened hair may already need additional moisture and conditioning. Excessive heat can make dry hair feel even rougher, frizzier and more difficult to manage.

Then we fall into a frustrating cycle:

Your hair feels frizzy, so you use the flat iron.

The repeated heat leaves the hair feeling drier.

The added dryness creates more frizz.

Then you reach for the flat iron again. 😂

The solution may involve more than turning up the temperature. Your hair may need better preparation, appropriate products, improved technique and fewer passes with the tool.

What Temperature Should You Use on Colored Hair?

There is no single temperature that is perfect for every person.

The best setting depends on your hair’s:

  • Texture
  • Density
  • Strand thickness
  • Porosity
  • Chemical history
  • Current condition
  • Natural curl pattern
  • Ability to hold a style

Fine, fragile or heavily lightened hair usually requires less heat than thick, coarse or resistant hair.

Start with a lower temperature and increase it only when necessary. Your goal should be to use the lowest effective temperature that creates the result you want.

If you are unsure what temperature is appropriate, bring your tool or tell your stylist which model you use. We can discuss a safer starting point for your hair.

Why Heat Protectant Is So Important

Heat protectant should be part of your routine whenever you use a blow dryer, curling iron, flat iron or hot brush. Options we carry include the REDKEN Quick Blowout Heat Protectant Spray, KENRA Professional Platinum Blow-Dry Spray and Living Proof PhD Heat Styling Spray.

Depending on the formula, a heat protectant may help:

  • Reduce moisture loss
  • Create a protective barrier
  • Improve smoothness
  • Reduce friction
  • Make the hair easier to style
  • Protect the appearance of your color
  • Reduce some effects of high-temperature styling

However, heat protectant does not make your hair invincible.

You still need to use an appropriate temperature, avoid unnecessary passes and give your hair breaks from heat when possible.

Make sure the product you choose is designed for the type of styling you are doing. A blow-dry product may not provide the same protection needed for direct contact with a flat iron or curling iron.

Stop Going Over the Same Section Repeatedly

You know who you are. 😂😂

If you repeatedly run a flat iron over the same section, you are exposing that hair to heat again and again.

Instead:

  • Work with small, manageable sections
  • Comb each section before using the tool
  • Use the correct styling products
  • Keep the tool moving
  • Avoid clamping too tightly
  • Use smooth, controlled passes
  • Stop once the section has been styled

If your hair requires countless passes to become smooth, the issue may be your technique, product selection, tool quality or the current condition of your hair.

More passes do not automatically create smoother hair. Sometimes they only create more unnecessary exposure.

Never Flat Iron Wet Hair

A traditional flat iron should be used only when the hair is completely dry unless you have a specialized wet-to-dry tool and are following its instructions.

If your hair is sizzling, stop.

High heat on damp hair can rapidly heat the water inside and around the strand, increasing the risk of severe dryness, bubbling damage and breakage.

Dry your hair completely before using a traditional flat iron or curling iron.

How to Reduce Heat Damage on Colored Hair

To protect your hair and color:

  1. Apply heat protectant before styling.
  2. Use the lowest effective temperature.
  3. Make sure your hair is completely dry before using direct heat.
  4. Limit repeated passes over the same section.
  5. Avoid using hot tools every day when possible.
  6. Use professional shampoo and conditioner for your hair type.
  7. Add moisture or repair treatments when recommended.
  8. Schedule regular trims to remove damaged ends.
  9. Turn down the temperature of your shower water.
  10. Ask your stylist to evaluate your routine.

Small changes can make a significant difference over time.

Does Heat-Damaged Hair Need Moisture or Repair?

Sometimes heat-damaged hair needs moisture. Sometimes it needs strengthening or bond repair. Often, it needs a balance of both.

Your hair may need moisture if it feels:

  • Dry
  • Rough
  • Frizzy
  • Dull
  • Tangled

It may need professional repair support if it feels:

  • Weak
  • Fragile
  • Gummy or overly stretchy when wet
  • Prone to snapping
  • Chemically compromised

A moisturizing mask can improve softness, and a bond-building repair treatment can help support strength, but neither can permanently reconnect a strand that has already broken or remove a true split end. Severely damaged ends may need to be trimmed.

I can use professional color, carefully place your lightener and protect the integrity of your hair during your appointment.

But what you do every day matters too.

Healthy blonde hair is a team effort. I will do my part behind the chair, and you have to do your part at home. 🤍

If your hair feels dry, keeps breaking, looks dull or no longer holds color the way it used to, please do not wait until the damage becomes severe.
