How Do Heat, Sunlight, and Pollutants Harm Your Hair: Top Solutions

Dec 26, 2022

Despite what you might see in shampoo commercials, your hair is not indestructible. In fact, it's quite vulnerable to damage from a variety of sources, including heat, sunlight, and pollutants. Here's a closer look at how these everyday hazards can harm your hair and what you can do to protect it.

Heat is one of the most damaging forces your hair has to contend with. Whether you're using a curling iron, flat iron, or blow dryer, too much heat can leave your hair dry, brittle, and prone to breakage. Sunlight is also tough on hair. 

UV rays can cause the protein in your hair to break down, leading to dryness, fizziness, and split ends. And finally, pollution can take a toll on your locks as well. Pollutants like smoke and smog can coat your hair in a layer of grime that dries it out and makes it look dull.

Fortunately, there are steps you can take to protect your hair from all of these hazard stages: air pollution risks. When styling your hair with heat tools, always use a heat protectant product to help create a barrier between your hair and the damaging effects of the heat. And be sure to limit your exposure to sunlight by wearing a hat or scarf when you're outdoors for extended periods of time.

Finally, wash your hair regularly with a gentle shampoo to remove any dirt or pollutants that may have accumulated throughout the day. By taking these simple precautions, you can help keep your hair healthy and looking its best.

What causes heat to cause hair damage?

You are more likely to get damaged hair from heat by using hot tools such as curling irons, flat irons, and blow dryers. Some hot tools do not allow temperature control. You may only have one set or a few basic options, such as low, medium, or high.

Some tools are more flexible but can reach temperatures exceeding 400 degrees F. It would be reasonable to assume that styling is more effective if the temperature is higher.

High heat can alter the shape of hair's keratin strands. Over 300°F will cause a conversion of -keratin into b-keratin. This eventually results in weaker hair, which is more susceptible to damage and a loss of elasticity. Your hair retains its molecular shape after the keratin has been melted. This is not reversible.

Understanding heat-damaged hair

Researchers from the Journal of Cosmetology & Trichology studied the effects of two heat settings on curly natural hair. They were 365 and 428 degrees F. The hair was classified as tightly curled before straightening.

Straightening hair was done 50 times at both temperatures. Next, the hair was dried by blow drying.

Hair that was straightened at 365°F did not experience any changes in its curls. 37% of participants who had their hair straightened at 428 degF couldn't get the natural curls back.

Although the hair was initially curled tightly, the final result was looser curls and waves that almost looked straight. 25% of the hair was not damaged by the higher temperatures.

Researchers also performed tensile testing on 50 straightened hair strands. This puts stress on the hair until it breaks. Straightened hair at 365°F did not suffer from more breakage or become weaker than it was before. Straightening hair to 428degF made them less elastic and weaker, which makes them more vulnerable to breaking.

How to manage heat-damaged hair

Is it possible to repair damaged hair? It's impossible to repair damaged hair after heat damage has caused irreparable damage to the hair structure. You have a few options to manage the situation.

You can trim your hair to remove any damage. However, this may require a more extensive cut, depending on the extent of the damage. It could take anywhere from a few inches to several inches.

You can manage your hair and cut the ends if you don't want to go short.

Hair masks should be used for porous hair. FuelupNutrify Protein Hair Masque is the best option.

This seals in moisture, making your hair feel soft. Products with keratin or silk in them will help your hair feel softer.

Your hot tools should be kept to a minimum setting. You should aim for temperatures between 200degF and 300degF when you curl, blow dry, or straighten your hair. You can use a heat protector and let your hair air dry as much as possible.

What causes sunburnt hair?

Your hair can be damaged by the heat of the day. This will not only ruin their appearance but also cause internal damage. How much sun exposure you have had directly affects the extent of the damage. While we all want to protect our skin from the sun's rays, we neglect to protect our hair from them. Our hair can also be affected, just like our skin. You should at least try to stop it if you are unable to.

What is the secret to making it work?

Sun rays are directed at the cuticles, which are the outermost layers of your hair. There are many layers of cuticles. These layers are there to protect the inner core against external conditions. The most intense radiation is received by the outer layers. The result is that the proteins and amino acids get damaged. The layers' protective ability is diminished to a minimum. Radiation can damage the core if it is not protected. The cells and cell membranes eventually start to rupture, and cell-structural impairment happens. This is how the sun damages your hair.

Sun damage prevention

Preventing a problem is better than treating it. There is always a chance your hair will not look the same after proper hair treatment.

Here are some tips to help prevent hair loss.

  • Fuelup Nutrify protein hair mask is the best option.
  • Hair treatments should be applied before the summer season begins. You can use a variety of home remedies, including vinegar treatment, Onion treatment, egg and mustard treatment, and organic treatment.
  • It may be best to cover your head. To protect your hair from the sun's harmful rays, you can use a headcover or hat.
  • Healthy hair is possible by using scalp treatments regularly.
  • Oil is naturally produced by your hair and scalp. Your hair can be damaged by applying Fuelup hair repair protein shampoo every day during the summer months. Dry shampoos should be readily available on the market.
  • To nourish your hair, you can directly apply vitamins or nutrients to your head.
  • You should stop using iron curlers to curl your hair. Iron curlers can weaken the outer layers, leaving the hair's core vulnerable to radiation.
  • You may need to wash your hair if you swim. Conditions can get worse from chlorine and salt in the pool water. Coconut oil is a great way to protect your hair from chemicals in the swimming pool.

What causes hair damage from pollutants?

Pollutants are all around us. Its harmful effects are on our largest organ, the skin.

These effects have been well documented. However, more research is showing that pollution can also impact the health of our scalps and hair.

Air pollution can cause hair to look dull, dull, and dirty.  

Understanding the negative effects

The particulate matter, which is made up of small particles and drops in our air ( pollution), can build up over time on the scalp. If the scalp is not properly cleaned and protected, this can cause significant hair follicle damage and even hair loss.

Your hair can become polluted by air pollution. Every strand can be affected by the daily dirt, dust, and fumes that you are exposed to on a daily basis.

Pollution damage prevention

Consider investing in shampoo systems that are specifically formulated to reduce the harmful effects of air pollution if you are concerned about air pollution. The right shampoo will remove any harmful debris from your scalp and hair strands and leave behind beneficial ingredients (oils, antioxidants, etc.) that will help to seal your hair's cuticle. If your hair has already been damaged, you can use hair growth oil.


What are the solutions to hair loss?

Certain nutrients can help you grow your hair and prevent damage from happening. Make sure to get enough iron, folic acids, and zinc in your daily diet. Hair can be protected by adequate protein and antioxidants from plant foods. Hair growth can be aided by certain vitamins.

Is it possible to repair heat damage

No, heat damage can't be reversed. The inner cortex can be damaged if the protein bonds to the hair are broken or the cuticles cracked. Your hair will become less flexible and weaker if the cortex is exposed.

How does heat damage affect hair?

Hair that is damaged by heat becomes fragile and breaks easily. Split ends are more obvious. Your hair may look dull and dry. It can be difficult to get your hair flat.
