Heavy shedding after 18 months fin + min

I’ve been taking finasteride + minoxidil in two separate tablets since November 2024 and have had good results. I recently switched to an all-in-one fin + min + biotin tablet from the same brand,with the same fin min strengths.

Since beginning of august I’ve noticed a fairly heavy increase in shedding. Some days are worse than others. However, I don’t think I’ve lost much density overall, and people have actually commented recently that my hair still looks thick.

I’m trying to work out what to do next and have a couple of concerns:

  • Could switching from the separate tablets to the combined tablet make a difference, even though it’s the same brand and the same fin/min strengths?
  • Should I switch to dutasteride in case finasteride is no longer controlling my hair loss?

Any advice would be appreciated!
