As if droughts, storms, wildfires, and days on end of triple digit temperatures (100º+ Fahrenheit) weren’t enough to worry about with climate change, there’s at least one more thing. It’s hair loss due to excessive heat.
Yes, excessive heat can diminish the quality of your hair and scalp. For the most part, it can worsen hair loss that is already underway. But it can also adversely affect people with relatively healthy, thick hair when breakage occurs midway down the hair shaft, forcing both men and women to start seeking hair loss solutions at the local hair loss treatment clinic.
For the most part this affects individuals who are exposed to high temperatures due to outdoor work, athletic pursuits in high temperatures (runners and bikers take note), and those who worship the sun, temperatures be damned. The effects are similar to when a person uses high-temperature styling tools such as hair dryers, curling irons, and straighteners, although prolonged exposure to heat leads to even worse effects.
There are several reasons why heat can diminish hair health:
The preventive solutions boil down to hygiene, applying antibacterial creams, and cooling down. A mild shampoo is less likely to strip out natural oils while washing away the dirt, bacteria, and fungi. And a cool water rinse will reduce the temperature in the scalp as it reduces the risk of infection. The natural thinning that occurs in hot weather is generally not permanent unless the scalp infections go untreated.
