Weather and Your Hair

Weather affects every aspect of our lives. Bad weather can make traffic a nightmare. It can disrupt our conveniences (electricity, television service, etc.). We plan trips around weather patterns (going to the beach in sunny summer weather, skiing in snowy winter weather). Weather can make us feel happy or sad, good and bad. It can help us feel refreshed and energized, or just plain tired.
 
With all the ways that weather affects us, it's no surprise that it can wreak havoc on our hair. There are many ways that weather affects the hair. Let's look at the effects of weather, season by season.
 
Summer:
 
Summertime brings thoughts of beaches and swimming pools, and lying in the sun to get a tan. The average person spends more time outdoors during the summer months, and two of the more common factors of summertime weather are heat and humidity. Any woman who has ever spent an hour styling her hair and stepped outdoors on a hot, humid day can tell you firsthand that heat and humidity can ruin a hairstyle.
 
The physical bonds in our hair are broken by the application of heat and water. This is why we are able to style the hair using wet sets on rollers, and by using blow dryers, curling irons, and flat irons. Exposing styled hair to a hot, humid environment causes these side bonds to break again, allowing the hair to return to its natural state. Naturally straight hair will have its curls start to collapse. Naturally curly hair that has been ironed will begin to frizz and revert back to its curly state.
 
Some styling products can help to seal the hair shaft and make the hair resistant to the effects of weather, but they can only do so much in very extreme weather conditions.
 
Another “weather effect” that’s common in the summer is sun damage. In the same way that UV rays from the sun affect the melanin in the skin, they also cause changes in the melanin in the hair. Prolonged sun exposure can lighten the hair, and sometimes, when dealing with artificial hair color, can alter the color to an undesired hue. The UV rays penetrate the hair shaft and disperse the melanin that gives the hair its color.

Winter:
 
The most common weather-related effects on the hair during winter come from the cold (or specifically the constant changes from cold to warm environments) and from static electricity.
 
Cold, dry air can cause the cuticle layer of the hair to lift, and going into a warm, dry indoor environment then leeches the moisture out of the hair, leaving it dry and frizzy. This also provides the perfect conditions for static, which can make the hair very unruly.
 
Wind:
 
The wind can also damage the hair. Exposure to strong, persistent winds can create tangles and snags in wavy and curly, long hair. The wind buffets the hairs against each other which roughens the cuticle layer causing the hairs to catch on each other. In addition, hair that is repeatedly buffeted in strong or gusting winds can develop split ends as the hairs brush against each other.
 
Most of these problems can be controlled with modern styling products, but there are limits to what the products can achieve. It’s easier to limit your exposure to the elements.
