Does Weather Affect Hair Growth?
Temperature can surely have an effect on the health and appearance of your hair, whether you live in a dry, cold region or use a hot curling iron frequently. However, there is no conclusive evidence that temperature can affect the rate at which your hair grows, which is typically roughly a half-inch each month for most people. Considering a few of the ways that temperature might impact your hair and developing a better awareness of your hair's natural growth process, on the other hand, can assist you in making informed decisions regarding hair care and styling in relation to temperature. Here is everything you need to know!
True or False: Does Summer Cause Your Hair to Grow Faster?
We are always delighted to see summer return to Michigan, where we are headquartered. Summer's splendor—sun-kissed days packed with outings to the pool and beach, outdoor barbecues with family and friends, and ample opportunity to explore new activities.
When discussing the benefits of summer, I'm frequently asked, "Does my hair grow faster in the summer?"
While your adorable pixie cut is unlikely to convert into a traditional bob in a few months, your hair may grow 10% faster during the summer than it would in a cold area during the winter. That is, unless you live in a climate where the changing of seasons results in radically variable temperatures.
The heat does not encourage hair development on its own; it is the enhanced blood circulation that stimulates hair growth. How? In the warmer months, we tend to be more physically active. Our bodies produce more hormones and work harder to keep us cool as a result of the increased exercise.
The National Institute of Health conducted a 1991 study titled "Seasonal Changes in Human Hair Growth" that lends validity to this theory. Although little research has been conducted on this subject and this study was conducted decades ago, the data is still very clear—warmer weather has an effect on our bodies and promotes hair development.
Did you know that every body hair, including your brows, grows in three stages? While eyebrow hair, scalp hair, and eyelashes all develop at varying rates, they all follow the same three-phase cycle (anagen, catagen, and telogen) as the NIH study. The anagen phase is the active growth period of hair follicles, during which they rapidly divide. Catagen is a brief transitional phase that occurs at the conclusion of the anagen phase. And then there is the telegen phase, which is the resting period. While all body hair, including scalp hair, undergoes the three-phase development cycle, not all follicles pass through each stage simultaneously. Thus, certain hair follicles are perpetually in the active growth phase, while others are dormant. All mammals' hair grows in this manner, but humans' hair is unusual in that it does not shed in hot weather and grows thicker in cold weather. Indeed, it appears as though the opposite is true, at least in terms of hair growth.
Simply remember that a balanced diet rich in biotin, vitamin C, B vitamins, omega-3 fatty acids, and minerals such as zinc and iron is important all year for a healthy body (and hair). However, the NIH study confirms what we have long suspected: Our hair grows faster in the summer. Therefore, if you're wanting to grow out a terrible haircut or achieve lusher brows through the use of EES, summer is the time!
Does Weather Affect Hair Growth In High Heat
By and large, excessive heat can result in brittle, damaged hair and broken ends. Excessive heat exposure is most frequently caused by prolonged use of heat-based styling products such as curling irons or hair dryers. While these gadgets are generally safe and healthful when used appropriately, they can have a detrimental effect over time. On the other side, heat can increase blood flow to scalp follicles and cause cuticle scales to open, enhancing the effectiveness of conditioning treatments. While heat can be detrimental to or beneficial to your hair depending on the situation, it generally has little effect on the rate at which your hair grows.
Does Weather Affect Hair Growth In Cold
Additionally, cold might have an influence on hair. In a therapeutic setting, cold can occasionally counteract the beneficial or detrimental effects of chemotherapy or medical hair treatments by decreasing blood flow to the scalp follicles. Cold air, as an environmental component, can exacerbate the brittleness, dryness, and fragility of hair, as well as increase static. While some claim that hair growth increases during the winter to give additional insulation, medical research has demonstrated that this is not the case.
Components of Hair
Hair fibers are composed of keratin proteins, which are also present in human fingernails and toenails, as well as in hooves, horns, and claws of animals. Hair fibers are composed of three layers; the outermost layer is a thin, transparent layer called the cuticle, which serves as a protective barrier for the hair. Within the cuticle is the cortex, a dense layer of melanin that determines the color of your hair. Additionally, the cortex determines whether your hair is curly or straight. The medulla is located in the very middle of the hair fiber and is responsible for reflecting light to give your hair its luster and tone. Each hair is surrounded by a follicle within the epidermis, and sebaceous glands produce oil to nourish and protect the hair.
Phases of Hair Growth
Three unique phases of hair growth occur. Anagen is the early period of hair growth, lasting between two and eight years. The length of anagen dictates the maximum length of hair that can grow, which ranges from about a foot to well over four feet. The hair follicle recedes for two to four weeks following anagen during the transitional catagen phase. Telogen's resting phase lasts two to four months. The hair does not develop during telogen, although it remains linked to the follicle. Finally, anagen may resume, and the new hair is pushed out by the growth process. This procedure results in the average person losing between 50 and 100 hairs per month, most frequently during showering or brushing hair.
Hair Growth Suggestions
While temperature alone cannot solve hair development problems, there are techniques to promote and preserve hair growth. As a general rule, maintain a healthy lifestyle that includes a balanced diet and frequent exercise, and take care of your hair with consistent hygiene and grooming routines. Massaging your scalp after a thorough hair wash is an excellent approach to stimulate the follicles and enhance blood flow. When in doubt, and especially when choosing an uncommon treatment or supplement, conduct extensive study and visit a reputable hairstylist, pharmacist, or physician.
