Does Heat Damage Hair?

Some heating devices do not allow temperature control. These can be low, medium, and high base settings or settings. Some units have some controls, but temperatures can exceed 400°F. You think the hotter the better the style, but it’s not.

Excessive heat can change the shape of the keratin hair roots. Heat above 300°F converts ⍺-keratin to beta-keratin, which damages hair, making it lose elasticity and become brittle. When keratin is damaged, the hair remains at the molecular level and cannot be regenerated.

How Does Heat Lead to Damaged Hair?

How Does Heat Lead to Damaged Hair?

One of the ways heat damages hair is by dehydrating it. Hair is made up of various components such as 4% oil, grease, and pigment, 17% water, and 79% keratin. The cuticle is the interior of the hair follicle and contains water molecules bound by keratin.

When the heat hits, hair loses its natural oils and water molecules change the hair’s protein structure. Heat quickly dries out moisture, affects the design of each hair follicle, and burns the outer layer of hair, causing breakage.

Damaged Hair Lacks Moisture

Hair cuticles are layered like a roof. In healthy hair, the loops are closed and flattened. When the hair falls out, the follicles are opened and swollen, causing the follicles to break and fall out. An extended cuticle produces more moisture.

The hat is the patron saint of animals. If the cuticle is damaged, the damage extends to the cuticle and the hair becomes more porous. Damage to the cortex can cause hair to become weak and brittle. Hair loss is classified as low, normal, or high. Wet the blow dryer in water to test the texture of your hair.

Have too much hair if the hair grows to the bottom of the bag. If the flow is weak to moderate, the porosity is normal. Heat can oxidize hair color, whether natural or dyed. This can be overkill, especially if the hair is very porous.

If you dye your hair, you are doing it too often, which can cause more damage. In a study published in the Journal of Cosmetology and Trichology, scientists examined the effects of two heat settings on naturally curly hair: 365 degrees Fahrenheit and 428 degrees Fahrenheit. Hair should be curled before styling.

Hair was treated 50 times in both seasons. The hair was then heated and air-dried to see how the treatment affected the curls. At 365°F, there was no change in the hair follicles. For 428°F curls, 37.5% of participants were unable to restore their natural curl style.

Although the hair starts out curly, the result is light, almost straight, or wavy. Only 25% of the heat-treated hair was undamaged. Researchers tested 50 black hairs under stress until they broke. 365°F braided hair won’t be too difficult to comb or style. At 428°F, gray hair becomes weaker, less elastic, and more likely to break.

There are many indications for treating heat-damaged hair. Damaged hair looks dull, dry, parched, and brittle. Divide the cuticle for a natural shine. Heat-damaged hair can become dull, gray, and misshapen, while loose hair does not look clean and beautiful.

On average, 50 to 100 hairs are lost per day, but if the skin is damaged, you may notice that more hair is falling out due to the damage. Can hair loss be treated? Although the structure of the hair changes due to heat, it is permanent. Still, you can cut your hair and get rid of the bad stuff.
