The Truth About Curling Irons and Hair Damage
I have heard horror stories of hair being fried and damaged BEYOND repair by curling irons. But there is a lot of debate about whether or not they damage hair.
Some claim that curling irons can cause heat damage, leading to split ends and breakage. Others say that if you use the curling iron CORRECTLY, it will not damage your hair.
So, what is the truth? Does using a curling iron damage hair? The answer is yes and no.
Hair damage caused by curling irons is typically due to HEAT and MECHANICAL damage.
Heat damage occurs when the curling iron’s heat DRIES out your hair, causing it to become more susceptible to breakage. Mechanical damage occurs when the curling iron’s clamp pulls on your hair, causing it to stretch and TEAR.
However, there are some things you can do to prevent both of these types of damage.

How to Avoid Damaging Your Hair With a Curling Iron
If you are CONCERNED about damaging your hair with a curling iron, there are some things you can do to prevent it.
Size of Curling Iron
First, make sure you use the correct SIZE curling iron for your hair type. Use a SMALLER barrel curling iron if your hair is thin or fine. Conversely, use a LARGER barrel curling iron if your hair is thick or coarse.
Second, ALWAYS use a heat protectant spray on your hair before using the curling iron. This will help to prevent heat damage.
Pro Tip: Coconut oil makes an excellent heat protectant and can be found at most grocery stores.
Third, be careful not to PULL or tug your hair while curling it, as this can cause mechanical damage. Instead, GENTLY guide the curling iron through your hair.
Release The Clamp Slowly
Fourth, slowly RELEASE the clamp on the curling iron when you are finished curling your hair. Do not just let go, as this can cause your hair to SNAP.
Use Lower Heat Settings
Finally, use LOWER heat settings on your curling iron. High temperatures can cause more damage to your hair.
Following these tips can help prevent heat and mechanical damage to your hair. You can even try using a flat iron instead of a curling iron to minimize damage.
Pro Tip: Try using a ceramic or tourmaline curling iron, as these materials emit negative ions that help to protect your hair from damage.

What to Do If You Have Already Damaged Your Hair With a Curling Iron
If you have already damaged your hair with a curling iron, there are some things you can do to repair it.
You can also follow this guide to learn how to take care of your hair if you frequently use curling irons.
Use a Deep Conditioner
Use a deep conditioner at least once a week to RESTORE moisture if your hair is dry and brittle from damage. 
Apply the conditioner to your hair and leave it on for at least 30 minutes. You can also leave it on overnight for extra hydration.
Be sure to read the label CAREFULLY of hair treatments to find a deep conditioner that is right for your hair type.
Using this will help your natural oils to better protect your hair from heat damage in the future to keep your hair healthy.
Pro Tip: You can also use leave-in conditioners and hair masks for extra hydration.
Trim Your Ends Regularly
If you have split ends from heat damage, it is essential to trim them regularly.
Split ends can TRAVEL up the hair shaft, causing more damage. By trimming your split ends, you can help PREVENT further damage.
If you are UNSURE how to trim your hair, you can visit a salon or ask a friend for help.
Long hair can be especially susceptible to damage from heat styling. If you have longer hair, you may want to consider getting a trim more often.
Give Your Hair Time To Recover
After you have damaged your hair with a curling iron, it is important to give it time to RECOVER.
This means taking a BREAK from using heat styling tools and giving your hair a rest. Curling hair every day can put a lot of stress on your locks, so giving them a break will allow them to recover.
Allow your hair to air dry instead of using a blow dryer. And if you must use heat, make sure to use the lowest setting possible.
Pro Tip: Try using a diffuser attachment on your blow dryer to help distribute the heat evenly to dry hair.
Get a Hair Cut
Lastly, if your hair is SEVERELY damaged, you may need to get a haircut to remove the damaged ends. While this may seem drastic, it can help your hair recover and prevent further damage.
Talk to your stylist about getting a trim or even a shorter style if your hair is highly damaged.
