Minimal daylight, dry skin, chapped lips, and, for some, serious hair shedding. Winter is harsh. For too many people, the cold, dark winter months bring with them increased hair loss.
Winter hair loss has a lot of reported sufferers—but no clinical research to back it up. There are no great scientific studies on seasonal shedding, but there are numerous reports and observations of this occurring. While there are some studies that point to seasonal patterns to hair shedding and hair loss, there is no known association between wintertime and hair loss.
So why does it happen?
The hair-growth cycle is comprised of four stages: The anagen (growing) phase, catagen (transitional) phase, telogen (resting) phase, and exogen (shedding) phase. The telogen phase is when grown hairs are securely anchored within the scalp, and basically just hanging out before the shedding phase begins and the growth cycle begins all over again. There are several theories about seasonal hair loss, one of which is that our bodies hold on to more hairs during warmer summer months to shield the scalp from UV exposure. Then, as part of the natural hair-growth cycle, the shedding of these hairs may happen to coincide with winter—but this would be highly dependent on the climate of where you live and your own personal sun exposure. More sunlight during the summer may trigger hairs to enter the telogen (or resting) phase, perhaps as an evolutionary form of extra sun protection. These are of course all just theories.
The facts behind it.
Environmental factors are a more likely cause of hair loss in winter. It is normal to lose between 50 to 100 hairs a day, and if you are brushing or washing your hair less, you may notice [the hair loss] more on days when you are brushing or washing hair. Cold weather often means less sweat, and many people report washing their hair less frequently in the winter. So the times people do wash their hair during winter, they notice more hair loss in bulk contrary as the normal hair loss they would witness with regular washing.
