Introduction
The normal range for daily hair loss is fewer than 100 hairs. Hair refers to the strands growing on the scalp; each person has approximately 100,000 hairs. Influenced by the body's metabolism, hair naturally sheds as a normal physiological phenomenon. However, the amount of hair lost naturally each day is generally minimal and typically does not exceed 100 hairs.
It is normal to lose up to 100 hairs per day. The detailed explanation is as follows:
Hair refers to the strands growing on the scalp. Each person has approximately 100,000 hairs. Hair protects the head from minor impacts and helps with sweat evaporation. Due to the body's metabolism, hair naturally sheds, which is a normal physiological phenomenon. However, the amount of daily natural hair loss is usually minimal and generally does not exceed 100 hairs.
If excessive hair shedding is observed in daily life—more than 100 hairs per day—this may indicate hair loss (alopecia). Hair loss can be influenced by various factors such as genetics, diet, unhealthy habits, medication side effects, infections, etc. Since causes vary, treatment methods also differ accordingly. Patients should avoid treating hair loss blindly to prevent inappropriate management. It is recommended that individuals experiencing hair loss seek medical attention at a hospital, undergo relevant examinations under a doctor’s guidance, identify the specific underlying cause, and receive targeted treatment.
