When is shedding season for humans




















Ever wondered why excessive hair shedding falls with the leaves come autumn? As cooler temps make our skin dry and crack, does the change in weather also invite seasonal hair shedding? Experts say yes. In a 6-year biochemical investigation, researchers studied hair samples from hundreds of women under a microscope. The verdict? Hair shedding happens more excessively during summer and fall months. Bottom line: seasonal hair shedding is a real concern.

Experiencing excessive shedding? Cozy up with your favorite frothy beverage as we pull back the curtain on seasonal hair shedding and how to stop it. What gives? Millions of people wondered the same thing and took to the internet for answers. An analysis of a series of search terms on Google Trends revealed a striking parallel:. The months when people searched for answers about hair loss directly matched the months of seasonal hair shedding. Considering the survey studied 12 years of data, likely not.

Hair is made of keratin, which are protein cells. While hair strands are technically lifeless, the follicles are abundant cells full of biochemical activity that regulate the hair growth cycle. Within the cycle are four phases: Anagen, Catagen, Telogen and Exogen. At any given point strands are in a different phase. When summer fades and we transition into fall, hairs enter the Telogen shedding Phase.

What is it about fall that sends our strands shedding in every direction? Alan Bauman. The heat of summer marks the beginning of seasonal hair shedding. Methods: Retrospective case study over a period of 6 years of apparently healthy women with the complaint of hair loss. All underwent biochemical investigations, and trichograms were made.

Results: After exclusion of patients with a disease or on drugs known to cause hair loss, women remained. Chances are, you're just fine. In fact, you may just be dealing with seasonal hair loss. It's one of the great ironies of life that hair grows unabated where we often don't want it like in the nose but then drops with abandon from the head, especially when the weather gets colder.

No surprise there, say experts. The thought here is that perhaps in the summer months, we hang on to more hair to provide increased protection from the sun," Emily Wise Shanahan , a Massachusetts—based dermatologist, tells Allure "A few months after, when we begin shifting into late fall and early winter, those hairs that we held onto during summer will make a transition into the shed phase.

Roberta Del Campo , a dermatologist in Miami, shares another theory: "The idea is that more hairs than normal are shed to make way for a thicker head of hair for the winter," she tells Allure , giving hope that the issue may resolve itself by the end of the year — maybe.

She also notes, "The holiday season tends to be a higher-stress time for many individuals and we know that stress plays a big role in hair shedding. And yes, joy of joys , the shedding may be more noticeable as you get older. Some hair loss is par for the course, but if you notice you're losing more hair around the cooler months, don't despair, as New York—based dermatologist Jeremy Fenton tells us.

Chances are, the hair you lost will be back in the future. According to Fenton, one study has shown that we have the highest number of hairs in the telogen phase in July, and a second smaller peak in April.

Fenton explains your scalp may simply be reacting to changes in daylight hours.
