Hello Dr ,I was hoping you to say it's my digestive issue , which is not getting nutrition to my hair, that is why I am so tired ,never hungry , I am always home , so 2 3 times sunscreen does not make sense to me , I do not go out during the day , my teeth are in very good shape I visit my dentist at least 2 times a yr , I have no gum or teeth problem, I practice very good dental hygiene, bad breath is from stomach issues I believe, from digestion problem . I have tried Minoxidil, my scalp breaks out and itches bad ,so I cannot do that , you mentioned the acid pills ,what is that for ,I am in the US , cannot get any medicine without prescription, unless it's over the counter , my Dr will not prescribe meds suggested by another Dr , are you in the US ? My mom ,my only sister does not have melesma , this all started from a product that made my skin itchy and I scratched my face during sleep , it was in one cheek , tried to get it out , .by microdermabrasion , did not work, peels Lazer ,my skin feels the pain or heat , it kept getting worse. I thought I would get a different outlook but everything you suggested has been done ,no results.
