Why Is Hair Shedding Increasing This Summer? Hidden Causes Explained

08/26/2025

Let’s uncover reasons for increased hair fall in the summer season: 

The summer seems to be a season of endless outdoor activities and fun, but not for everyone. Seeing a few of your hair strands falling out daily is pretty common and doesn’t seem to be concerning. However, when hair fall starts increasing, it starts taking a toll on your mental health, causing you to suffer mentally. Many people associate a full head of hair with beauty and confidence. While losing hair in summer may be concerning, it is highly manageable with the right techniques and tricks. Let’s check out the common causes of hair fall in males and females in summer. 

UV damage:

The highest damage to hair is caused by the UV rays in the summer season, making you prone to hair loss and brittle hair. Whenever we head out in the sun during the summer season, our hair is exposed to the harmful UV rays, which, as a result, absorb the moisture from the scalp and hair, making the hair look brittle, dehydrated, and discoloured.

Chlorine water:

If you are not living with hydrophobia, swimming must be your go-to activity in the summer. Going swimming with your friends seems to be highly joyful until it starts affecting your hair health. Yes, you heard it right. Swimming does affect your health and even causes hair loss. Almost every swimming pool adds chlorine to the water, which can dry out the hair and lead to brittleness.

Environmental stress:

Living in a city where pollution is high, the air quality is poor, and the humidity is at its peak creates the perfect environment for dandruff to develop and spread across the head. Dandruff-causing germs need high temperatures to evolve and spread. If you have dandruff, don’t ignore it. Doing so can lead to an itchy and irritated scalp, which eventually causes hair loss.

Nutrition deficiencies:

The season can’t be the culprit all the time; sometimes your body can trigger hair loss. If you have a nutritional deficiency, you are likely to have hair loss. In order to keep your hair stronger, your body needs the following vitamins and minerals: iron, zinc, biotin, vitamin D, etc.

Excessive swelling and scalp buildup:

Seeing yourself sweating and losing energy seems pretty common in the summer season. The sweat mixes with the dirt and oil present on the scalp, clogging the hair follicles. The clogged hair follicles increase the chances of developing dandruff and fungal infections, making you prone to hair loss.

Hair styling habits:  

Checking your hair before going out is an essential part of our routine. In order to make our hair look attractive and good, we use a lot of hair styling products like straighteners, blow dryers, and wax, which, as a result, damage hair and cause hair loss.

How to mitigate hair loss in summer?

In order to reduce your risk of coming across hair loss or hair shedding in the summer, abide by the following tips:

Look after your scalp:

In the summer, our scalps tend to produce more sweat and attract dirt and oil, making us prone to dandruff and hair loss. In order to prevent such outcomes, use a nourishing and clarifying shampoo two to three times a week. This practice will help you keep your scalp clean and dandruff-free. 

Protection from sun damage:

If you are prone to hair damage in summer, protecting your hair from damage is key. Whenever you head out in the sun, it is paramount to cover your head to prevent the sun's rays from hitting your hair and scalp directly. Use a cap or a scarf to cover your head.

Keep your hydration game stronger:

In the summer, we tend to sweat a lot, raising the need for strong hydration. Aim/try to drink 2 to 3 litres of water daily to keep yourself hydrated and away from hair loss.

Maintain a distance from heat styling products:

Try to limit or avoid as much as you can heat styling hair tools as much as possible during the summer season. The heat that these devices emit severely damages your hair and affects your scalp. 

Customize your diet:

Hair loss in the summer season is more prevalent than you think. Having a balanced diet with enough protein and micronutrients can help you maintain your scalp and hair health. If your diet lacks protein, iron, biotin, and vitamin D, it could be a potential risk factor for hair fall. 

The takeaway:

Saying goodbye to between 50 and 100 hair strands per day is considered normal and not a cause for concern. However, if these numbers continue to accelerate, it may be concerning and lead to numerous complications. There are many sudden hair loss causes as mentioned above. You may see these numbers surpassing in the summer season, but that can be managed with a broad range of techniques. There are multiple natural ways that can help you slow down hair shedding in summer. Stick to the aforementioned tips to manage hair fall in the summer. Despite following this regimen, if you don’t see any favourable results, consulting a doctor is worthwhile.
