Many people notice an increase in hair loss as summer approaches, possibly due to a poorly understood phenomenon called seasonal hair loss, which typically occurs in early spring.
This may be similar to how animals shed their “winter coat” when the temperature rises.
Harley Street hair expert Dr. Hugh Rushton said, “While we don’t have hair to get rid of, some of us often lose more hair this time of year.”
He noted that seasonal hair loss affects some people more than others, and it can also happen as we transition from summer to fall.
The trichology professor added: “For some people, this condition only occurs in the spring, for others it only occurs in the fall, and for some, unfortunately, it can be both.”
Why does seasonal rainfall occur?
Hair goes through a cycle of four distinct phases: anagen, catagen, telogen and exogen.
According to Dr. Rushton, seasonal shedding occurs because a larger percentage of hair growth than usual enters the completion phase of the hair growth cycle.
This transition usually occurs during the winter or summer solstice, which are the shortest and longest days of the year.
But you will only notice hair loss after about three months.
The exact cause of seasonal hair loss is unknown, but scientists believe it may be due to the change in light levels at each solstice.
Dr. Rushton explained that hair follicles contain a number of photoreceptors such as CRY1, CRY2, OPN3 and OPN4 that respond to light.
He hypothesized that changes in light levels as the days get longer or shorter may stimulate photoreceptor cells in the hair, causing some hair to move into the next phase of the hair growth cycle.
Dr. Rushton continued: “Because more hair reaches the terminal phase at the same time, hair loss tends to occur in a shorter time frame, making it more noticeable and making people think they have a hair loss problem or are suffering. from other problems. Normal level of hair loss.
“It’s important to note that seasonal hair loss should last a maximum of two to three weeks,” he added.
Luckily, any hair that has fallen out will grow back. But if the hair is constantly falling out, it may be due to another reason.
Dr. Rushton said that “in such cases, it may be helpful to seek the advice of a trichologist, who can help determine the cause of increased hair loss and suggest appropriate treatments for this condition.”
