How long does it take for hair loss caused by taking emergency contraceptive pills to recover?

Hair loss after taking emergency contraceptive pills usually recovers within 1–3 months. For most people, hair shedding gradually decreases about one month after stopping the medication, and hair growth typically returns to normal within three months, so there's no need for excessive anxiety. If hair loss persists beyond three months without improvement, or is accompanied by scalp discomfort, it is advisable to seek medical attention promptly.

Emergency contraceptive pills contain a high dose of progestin, which can temporarily disrupt the body's hormonal balance and affect the hair follicle growth cycle, causing some hairs in the growth phase to prematurely enter the resting phase and fall out. This type of hair loss is temporary; once hormone levels return to normal, hair follicle function will also recover accordingly.

Individuals with better physical health and stronger hormonal regulation abilities tend to recover hormone balance more quickly, resulting in shorter duration of hair loss—often improving within 1–2 months. Those with sensitive constitutions or pre-existing endocrine issues may take longer to reestablish hormonal equilibrium, potentially extending the recovery period to three months, although it generally does not exceed this timeframe.

In daily life, consuming foods rich in protein and vitamins—such as eggs and spinach—can be beneficial. Reducing hair perming and dyeing, avoiding over-cleansing, maintaining regular sleep patterns, and refraining from staying up late can help regulate hormones and promote hair regrowth.
