115 days since h pylori stomach ulcer treated. Hair loss neglible compared to what it was. When will regrowth be noticeable?

I can't say of the H. pylori is a coincidence or related without knowing more. However, the facts of the question are straightforward: the individual once shed 400 hairs and now shed 10. If this continues regrowth should be noticeable in 5 months to 6 months. Now keep in mind whether this regrowth is alot or a little depends on a) how many months you shed at a rate of 400-500 b) whether you developed follicular miniaturization from the pronged shedding and therefore now have more androgenetic components than you once had and c) whether shedding returns. All three of these factors will need to be considered to determine if you'll have a little bit of regrowth or a significant amount of regrowth. See a physician if concerns persist.

Wait until the medications are off for 6 months and they you will know if the hair loss has reversed because that is the length of the hair sleep cycle
