Heat-Damaged Hair vs Healthy Hair
The most significant difference between heat-damaged hair and healthy hair is the LOSS of elasticity.
When your hair is heat-damaged, the bonds that give it structure have been broken down. This can happen from over-processing, HEAT STYLING, or exposure to UV rays .
Your hair may feel dry and straw-like, which will be DIFFICULT to manage. You may also notice that your heat-damaged hair is more prone to breakage and split ends.
On the other hand, HEALTHY hair is well-moisturized and elastic. It is easy to style and manage and less likely to break or split.
So, how can you tell the DIFFERENCE between heat-damaged and healthy hair? I’ll be happy to take you through it.
How to Tell if Your Hair is Heat Damaged?
There are a few key signs that will HELP you determine whether your hair is heat-damaged.
One of the first signs is that heat-damaged hair will feel dry and BRITTLE to the touch. You may also notice that your heat-damaged hair is more difficult to style because it lacks elasticity.
Another sign of heat DAMAGE is split ends. When your hair’s bonds are broken, the ends of your hair can become frayed and split.
Finally, heat-damaged hair is often more PRONE to breakage. This is because the bonds that hold your hair together are weak and can snap easily.
How to Tell if Your Hair is Healthy
In contrast, healthy hair is silky, smooth, and ELASTIC. It is also easier to manage and style.
Healthy hair has a healthy CUTICLE, which is the outermost layer of your hair. The cuticle helps to protect your hair from damage and keeps it looking smooth and shiny.
Another sign of healthy hair is that it is well-moisturized. This means that your hair is NOT dry or brittle and is less likely to break or split.
Finally, healthy hair is often more FLEXIBLE and less likely to break. This is because the bonds that hold your hair together are strong and can withstand more heat-styling and processing.
How Damaged is Your Hair?
I know how important it is to be able to tell whether or not your hair is DAMAGED, and that’s why I have this quick list of things to check for.
This way, you’ll have a good idea of whether your hair needs repairs.
1. Feel the Texture of Your Hair
One of the first things you’ll want to do is run your fingers through your hair and FEEL the texture. It is likely heat-damaged if your hair feels dry, brittle, or straw-like. It is probably healthy if your hair feels silky, smooth, and elastic.
Pro Tip: Hair treatments that contain coconut oil and other natural oils have the most nourishing effect on your hair.
2. Check for Split Ends
Another thing you can do is look for split ends. To do this, take a SMALL section of your hair and look at the ends. If you see any fraying or splitting, then your hair is probably heat-damaged.
3. Examine Your Hair’s Cuticle
The cuticle is the outermost layer of your hair and helps protect it from damage. To check the HEALTH of your cuticle, take a small section of your hair and look at it closely. If the hair cuticles are raised or damaged, then your hair is probably heat-damaged.
Pro Tip: A hair mask is a great way to maintain hair health and take care of the hair shaft as well as the cuticles. It works on straight hair, curly hair – all kinds.
4. Check for loss or Breakage
Finally, you’ll want to check for hair loss or breakage. To do this, take a small section of your hair and gently PULL on it. If you see any hair loss or breakage, then your hair is probably heat-damaged.
Pro Tip: If you notice your hair SHEDDING more than usual, this can also be a sign of hair loss – especially while you are shampooing or washing your hair.
5. Are There Multiple Tangles?
One of the heat damaged hair symptoms is that it is more challenging to style because it LACKS elasticity. This can also cause your hair to become more tangled.
To check for tangles, take a SMALL section of your hair and try to COMB it. It is probably heat-damaged if you find multiple tangles or your hair is difficult to comb.
6. Has it Lost Elasticity?
Another sign of heat damage is that your hair has LOST elasticity. To check for this, take a small section of your hair and GENTLY pull on it.
If your hair stretches and then snaps back into place, it is probably heat-damaged.

Another sign of heat damage is dry hair. To check for this, take a small section of your hair and RUN your fingers through it. If your hair feels dry and brittle, it is probably heat-damaged.
To FIX heat-damaged hair, deep conditioning treatments can moisturize the hair follicles and bring life back to the hair strands.
