The end of summer and the commencement of fall bring seasonal hair shedding. Watching your hair on your brush or the bathroom floor can cause panic. You might wonder whether this is normal or you should be concerned.
The average hair shedding range is about 100 hairs daily; this can increase after shampooing or other hair care practices. (1)
You may notice increased hair fall during certain times of the year, especially during the fall. It is called seasonal shedding, which you may experience in August/September.

Seasonal Hair Loss Based on Research
During March, the anagen phase follicles peak at over 90% and fall to a trough in September. (2)
Hair shedding peaks around August or September when anagen has the least follicles. This time, hair loss is about 60 per day, more than double that in winter.
Beard growth is low in January and February; the growth increases from March to July and peaks at about 60% above winter levels.
There is maximal telogen proportion at the end of summer and the advent of autumn. The climate (sunshine hours) is not a factor in the periodicity of telogen percentage or hair fall. (3)
Reasons for Hair Fall in Summer
The following reasons lead to hair fall in summer.
1. Sun exposure
Excessive sun exposure leads to hair shaft structural impairment. In photochemical impairment, hair proteins and hair pigments degrade. Hair proteins degrade at a wavelength of 254-400 nm.
UVB radiation causes hair protein loss, and UVA changes hair color. (6)
2. Excess sweating
The roles of the follicular bulge region and sebaceous glands are crucial, as they are responsible for hair follicle destruction. (9) Increased sweat can build up on your scalp and clog the follicles, leading to hair fall.
3. Chlorine in the swimming pool
During summer, people go for a swim to beat the heat, where they are exposed to chlorinated pool water. Pool swimmers often complain about damaged hair.
The strong oxidizing power of chlorinated pool water can lead to hair damage. (10)
The scalp is unique as it has many sebaceous and sweat glands, thick terminal hair, and high relative humidity, leading to a thriving colony of microbes. (11)
Not keeping the scalp clean causes dandruff, which in turn leads to irritated and itchy scalp, causing hair loss.
Anti-Hair Fall Home Remedies This Summer
Follow these anti-hair fall remedies at home this summer.
1. Apply aloe vera to your scalp and hair
2. Apply onion juice to the scalp
A study on onion juice reported that 87% of the patients treated with onion juice for 8 weeks experienced hair regrowth compared to the 13% who used water. (15)
3. Apply glycerin
Glycerin provides softness, smoothness, and suppleness to your hair. It is used as a conditioning agent in shampoos. (16)
Glycerin contains water that prevents hair thinning and hydrates the hair follicles. It penetrates deep into your hair and scalp to moisturize them. (17)

Which season is best for hair growth?
In March, the anagen phase follicles peak at over 90% and fall to a trough in September. Therefore, March may be suitable for hair growth. (2)
The maximal proportion of the telogen phase is at the end of summer or the beginning of autumn. The climate is not the factor in the periodicity of telogen percentage or hair fall. (3)
How to take care of your hair at home during summer?
At-home hair care includes using hair masks made with aloe vera, yogurt, or eggs weekly to condition your hair. Also, having a good hair care routine during summer can give you nourished and healthy hair.

Additionally, you can wear heat-protectant hair creams or serums to keep the damage away.
