LOUISVILLE, Ky. (WAVE) - It is No-Shave November (also known as Movember), a month where many put down the razors to spark a conversation and raise awareness about cancer and men’s health. Show So, does the chilly November air help with hair growth? Warm air holds much more moisture than cold air. This means that as temperatures drop, the air holds less moisture. The relative humidity is defined by the National Weather Service as a "measure of the actual amount of water vapor in the air compared to the total amount of vapor that can exist in the air at its current temperature." The relative humidity is dependent on the correlation between moisture content and the temperature. It is possible to have 100% humidity at 20 degrees and 80 degrees, but they feel very different. This is why dewpoint is a better indicator of how humid it will feel outside. Dewpoints below 55 degrees typically feel dry and comfortable, while dewpoints over 65 degrees feel incredibly muggy.
Since cold air holds less moisture, that leaves hair drier. Experts recommend using hydrating hair masks during colder months to keep hair healthy. Dry hair is dull hair; the absence of substantial moisture contributes to a lack of shine. Dry hair is also more brittle, according to experts. This causes hair to be more susceptible to split ends. Dry scalps also can contribute to hair loss; dry scalps tend to grow brittle hair that excessive friction (like when we pull hats on and off during the winter) can easily break. Studies show that cold weather does not lead to hair loss. A lack of humidity and hydration is more often the culprit. A six-year study of 823 women at the University Hospital of Zürich found that they lost the least amount of hair during the winter. It showed that there was a peak in hair shedding in the summer, with a second, less significant, peak during the spring. Research also shows that the body produces more melatonin in the winter, which helps to regulate the hair growth cycle and thus keeps hair from shedding. Another study from the University of Bradford studied 14 Caucasian men in Sheffield, U.K., and found that their beard and leg hair grew the least in January and February. Hair growth for these men peaked in the summer months but their hair shed the most during August and September.
Here’s the thing though, hair goes through a cycle of growth and rest. During the anagen, or growth phase, hair follicles produce a hair shaft from root to tip. The anagen phase can last a few years. The regression, or catagen phase, signals the end of growth for your hair. Follicles shrink through the catagen phase, and the hair club is formed; this cycle lasts about 10 days. Hair’s resting phase, telogen, is when hair can fall out. During the telogen part of the cycle, follicles reset and get ready to start the next growth phase. Each hair goes through the growth cycle at different times. If they didn’t, all our hair would fall out at one time! Now temperatures have plummeted, most of us are avoiding venturing outside as much as possible, coupled with cranking up the central heating indoors and piling on the layers. But what is all this doing to our hair? Does a change in the weather really affect hair growth? Read on to learn about about hair loss during winter...  Do we experience more hair fall in winter?While many other mammals grow thick fur coats in the winter, which they shed in the summer (anyone who’s ever owned a cat will know this all too well), the received wisdom is that for us humans, the opposite is true – making us unique as a species (having opposable thumbs is quite nifty too!). But while many people think that the colder weather makes us lose our hair – this is technically a myth. A six-year study found that actually we shed the least amount of hair in winter. So we’re similar to many of our furry friends in that respect – in fact, during the winter our bodies go into a similar ‘hibernation’ mode, producing more melatonin (the sleep hormone), which also regulates hair production. But don’t get too smug. The above information accepted, there are indirect ways that we can lose more hair in the winter, which goes hand-in-hand with the changes in lifestyle it entails. For example if we happen to feel lower during the winter months – coupled with the stress of Christmas and tax season in January – the increase in ‘stress hormone’ cortisol can have a knock-on effect when it comes to hair loss. (Read more about it here.) Plus the cold, harsh weather and moisture-zapping central heating can result in a dry scalp – which can lead to irritation and flakiness, both of which are big factors in hair loss. Winter hats can also cause friction on the hair and scalp, causing the hair shaft to break or uproot altogether.

How can I protect my hair from cold weather?5 Tricks to Protect Your Hair from Cold Temperatures. Wear a hat to protect your hair from cold temperatures. ... . Minimize hair washing during the winter. ... . Apply natural oils before shampooing. ... . Use a deep conditioning treatment once a week. ... . Keep your hair healthy with regular trims.. Does cold weather make hair thinner?Many people who spend excessive time outdoors in the cold temperatures also experience a dry scalp, which can lead to hair loss as well. The hair becomes brittle due to a lack of moisture, and a person may notice that breakage occurs more easily. Over time, the hair may become noticeably thinner.
Why does my hair get weird in cold weather?It occurs because cold air contains less moisture than warm air, which then dries your hair out making it weak and brittle. To combat this classic winter hair problem and prevent the frizziness, you need to put the moisture back into the locks.
Does cold climate increase hair growth?“Hair does not grow quicker in winter, at least not on humans,” says John DeSpain, a dermatologist at DeSpain Cayce Dermatology Center & Medical Spa in Columbia, Missouri.
