Have you ever noticed more hair shedding during certain times of the year? If so, you’re not imagining it – seasonal hair loss is a real phenomenon.
For many, it becomes especially noticeable in the summer and autumn. While it can be a little unsettling, understanding why it happens and what you can do about it can help put your mind at ease.
Here, we’ll explore what seasonal hair loss is, how long it lasts, and how you can prevent and treat it.
What is seasonal hair loss?
Seasonal hair loss refers to an increase in hair shedding that occurs during specific times of the year. Many people experience it in the late summer or early autumn, but it can also happen in the spring. This kind of hair loss is usually temporary and related to the natural hair growth cycle.
Our hair goes through three main phases. This includes the growth phase (anagen), the resting phase (telogen), and the shedding phase (exogen). At any given time, about 90% of the hair on your scalp is in the growth phase, while the remaining 10% is in the resting phase. After the resting phase, hair naturally sheds to make room for new growth.
Seasonal hair loss occurs when more hair than usual enters the resting and shedding phases simultaneously, causing a noticeable increase in the amount of hair you’re losing.
How long does seasonal hair loss last?
The good news is that seasonal hair loss is typically short-lived. Most people notice increased shedding for about 6 to 8 weeks before things start to return to normal.
If you’re concerned about how much hair you’re losing, it can be helpful to monitor it closely. A bit of extra shedding during seasonal changes is normal, but if you notice more severe hair loss, it’s worth consulting with a professional to rule out other potential causes, such as stress, hormonal imbalances, or nutritional deficiencies.
It’s also important to remember that everyone’s hair cycle is different, and some people may experience more noticeable shedding than others. In most cases, once the seasonal shedding phase is over, hair growth should resume its normal pace.
Other reasons for hair loss
If your seasonal hair loss seems excessive or persists for longer than usual, it’s always a good idea to consult with a hair loss specialist. They can help you identify whether your shedding is related to seasonal changes or if there might be other factors at play.
- Genetics: Androgenetic alopecia is the medical term for male or female pattern baldness which is also known as hereditary alopecia as it runs in families.
- Hormones: Many females who experience androgenetic alopecia develop it after menopause. Hormones may play a role alongside genetics. Pregnancy is another time of fluctuating hormones that can be marked with temporary hair loss.
- Stress or illness can result in telogen effluvium which is when the healthy growth cycle is affected, causing more hair than usual to fall out at any one time.
- Medications: Certain medications can result in hair loss. Chemotherapy and radiation therapy can push large amounts of hair to fall out rapidly during the anagen phase of the hair cycle.
- Underlying health conditions: Certain conditions such as thyroid disease can result in hair loss.
- Alopecia areata: An autoimmune condition where the immune system attacks the hair follicles.
- Traction alopecia: Hair loss due to certain hairstyles that cause trauma to the hair follicles and may result in scarring and permanent hair loss.
