Hair loss caused by seasonal changes is a normal hormonal response when follicles shift into resting stages due to variations in daylight.
Seasonal shedding is typically mild and resolves within two to three months, unlike chronic telogen effluvium, which lasts past six months and is triggered by stress or illness.
Dr. Mayank Singh advises consulting a doctor if hair shedding continues past three months, creates visible scalp thinning, or follows significant stress or illness.
