How to Fix Heat-Damaged Hair? | 5 Easy and Natural Ways

We all love using hot tools like hair dryers, flat irons, and curling wands. They help us style our hair in so many fun ways. But using too much heat can actually damage your hair over time. When you use these tools, the high heat can make your hair dry, brittle, and frizzy. The damage happens eventually as you keep using hot tools. But how can you fix the hair damage from heat?

The first thing is you need to be gentle to fix heat-damaged hair. Use a good hair mask or deep conditioner each week. With some care, your heat-damaged hair can heal and look healthy again. In this blog, we'll explore the signs of heat-damaged hair and the ways to fix it in detail.

How Heat Leads to Damaged Hair?

Heat can damage your hair if you use it too much. Here's how it damages your luscious locks:

When you use heat-stying tools like blow dryers, flat irons, or curling wands, the high heat actually breaks down the protective outer layer of your hair strands, called the cuticle. The cuticle helps keep moisture in your hair.

Once the cuticle is damaged, hair loses porosity (the ability to retain moisture), leading to dry and brittle strands. Additionally, the inner core of the hair strand is exposed, making it weak and prone to breakage. These are the harsh realities of heat damage to hair. The more you use hot tools, the more damage builds up over time. The heat roughens your hair cuticles, leading to frizzy, unmanageable hair that tangles and breaks easily. While a little heat-styling can be good sometimes, too much heat is sure to damage your lovely locks severely. So, be careful with those hot tools!

What Does Heat Damaged Hair Look Like?

Identifying heat-damaged hair is essential to address the issue effectively. Here are 5 key signs you need to look out for:

Dryness and Dullness

Your hair loses its shine and looks dull and lifeless, which is one of the first signs of heat-damaged hair. Excessive heat strips away the outer layer of the hair cuticle, resulting in a lack of shine and a dull appearance.

Excessive Frizz

When hair is exposed to high temperatures, it loses moisture, and its protective cuticle becomes rough. This makes the hair strands prone to frizz. No matter how much you brush or the product you use, the frizz just keeps appearing.

Split Ends

Excessive heat weakens the hair strands, causing them to split at the ends. If not addressed, split ends make the hair look unhealthy and lead to further damage and breakage. Regular trims and proper hair care can help prevent and manage split ends caused by heat damage.

Tangling

When your hair has taken too much heat, it often becomes tangled and difficult to manage. Those rough, raised cuticles from hot tools cause the hair strands to snag and knot up constantly. No matter how much you brush,  tangles in that dry, damaged hair seem to form by the minute.

Lack of Elasticity

Heat-damaged hair often loses its natural elasticity. Healthy hair can stretch and bounce back without breaking easily, but excessive heat weakens the hair's protein structure, resulting in reduced elasticity. When you pull or tug on those damaged strands, they just break right off instead of stretching.

Heat-Damaged Hair vs Healthy Hair: Side-by-Side Comparison

It's easy to see the difference between heat-damaged (unhealthy) hair vs healthy, undamaged hair when you compare them side by side. Let's take a closer look at the characteristics of each:

Whereas, healthy hair appears shiny and smooth.

How to Fix Heat Damaged Hair?

If your hair is damaged from too much heat styling, don't fret! There are several effective techniques you can use to help revive heat-damaged hair. Check out our 5 easy techniques to fix heat-damaged hair.

1. Trim the Split Ends:

One effective way to fix damaged hair is to trim those pesky split ends. Cutting off the damaged ends helps prevent further splitting and promotes healthier hair growth. Regular trims every 6-8 weeks can keep your hair looking and feeling healthier.

2. Deep Conditioning Treatments:

Deep conditioning treatments are essential for fixing hair damaged by heat. Heat sucks all the moisture out of your strands, leaving them dry and brittle. Rich, hydrating hair masks fill much-needed moisture back into those dry hairs. Look for deep conditioners packed with nourishing ingredients like shea butter, oils, and proteins.

3. Air Drying

Let your hair dry naturally without the use of heating tools. Heat-free drying helps prevent further damage and allows your hair to retain moisture. If you must use heat, apply a heat protectant spray or serum to create a barrier between your hair and the styling tool.

4. Gentle Hair Care Practices

When your hair is damaged from too much heat, you must treat it with extra care. Being rough or aggressive with damaged strands will only cause more breakage. Use a wide-toothed comb or a brush with soft bristles to avoid causing further damage or breakage. Avoid pulling on knots, as this can lead to more harm. Furthermore, choose hair care products that are gentle and moisturizing to promote the repair and nourishment of your damaged hair.

5. Hydrate From Within

Fixing damaged hair also involves hydrating it from the inside out. Make sure to drink plenty of water and maintain a healthy diet. Staying well-hydrated promotes healthy hair growth and improves the overall condition of your hair.

Try Theradome to Stop Hair Loss from Heat Damage

Too much heat causes hair to start falling out. When hair gets dry and damaged from overheating, it becomes weak and brittle. The strands break off easily, resulting in excessive hair shedding and thinning areas. If the heat damage continues, the excessive breakage can eventually lead to hair loss.

To stop this heat-induced hair loss and regrow those thinning areas, try using the Theradome laser helmet. Theradome's special lasers stimulate the hair follicles and increase blood flow to the scalp. The helmet helps weak, damaged follicles revive and grow new, healthy hair strands. With consistent Theradome treatments, you can prevent shedding, strengthen weak areas, and regrow fresh hair, even after severe heat damage.

Conclusion

Taking good care of your hair is so important, especially if it has been damaged by too much heat styling. While hot tools like blow dryers and flat irons can temporarily give you great looks, long-term heating causes severe damage. You can fix the heat-damaged hair by cutting back on heat, using gentle hair practices, and treating your strands with lots of hydrating masks and nutrients. With patience and the proper regimen, your hair can revive from heat damage and look healthy again.
