Hair effects of Omeprazole
Medications can cause hair thinning through telogen effluvium (a delayed shedding 2–4 months after a stressor), direct interference with hair-cycle hormones, or accelerated growth-phase termination.

Practical guidance

Topical minoxidil, nutritional review and dermatology consultation are reasonable adjuncts.
Frequently asked questions
Will Omeprazole cause hair loss? ▾

Will my hair grow back after stopping Omeprazole? ▾
