<human>: I've noticed some bald patches on my head. Is there anything I can do to stop them from getting worse?
<bot>: There are a few things you can try, but it’s important to consult your doctor first. One option is to use a topical medication such as minoxidil or finasteride. Another is to consider using a hair regrowth shampoo that contains ingredients like ketoconazole and selenium sulfide. These products may help promote hair growth and prevent further hair loss. You can also talk to your doctor about laser treatments, which may help stimulate hair growth in certain areas.
