Hair fall after typhoid is usually due to telogen effluvium, a temporary shedding phase that improves in 3 to 6 months. Continue 5% minoxidil regularly, eat a protein-rich diet, check iron/Vitamin D levels, and avoid stress; hair growth typically recovers with time.

Four months is too early to judge results, as minoxidil typically takes six to twelve months of consistent use to show visible improvement. I do not recommend switching to 10% minoxidil, as higher strengths significantly increase the risk of scalp irritation and side effects without proving more effective. Instead, for men, the standard regimen for 5% minoxidil is twice daily, so you may want to increase to this frequency. For better results, you can discuss adding an oral DHT-blocker like Finasteride with your dermatologist. Please consult your doctor before altering your routine or starting new medications.

Yes, your mother can safely use topical minoxidil for hair thinning, even after stopping thyroid medication, as it is not contraindicated for well-controlled subclinical hypothyroidism (elevated TSH levels with normal T4 levels). Minoxidil works locally on the scalp to stimulate hair growth and does not affect thyroid function. Her hair loss may be related to hormonal changes after stopping long-term thyroid treatment, which can sometimes cause temporary shedding. She should start with the recommended dose for women and monitor for scalp irritation. If she develops any unusual symptoms or has other health conditions, consult her doctor before continuing.
