How Do Heat, Sunlight, and Pollutants Harm Your Hair: TopSolutions
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 he 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.
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, straighten your hair. You can use a heat protector and let your hair air dry as much as possible
