Hair fall and thinning. Issues,

I have been experiencing hair fall and hair thinning consistently for the past one year. I believe this may be linked to chronic indigestion, which I’ve been dealing with for some time. I’ve noticed some improvement when using multivitamins and applying serums, but the results have been limited. Previously, I used Bondress Pro Serum along with Hair Fact Tablets (Men’s variant), which offered mild benefits. However, Bondress Pro Plus is currently unavailable, and I am not in proximity to the prescribing clinic anymore. I am not comfortable using minoxidil, as I am concerned about its rebound effect and long-term dependency. I’m looking for a clinically effective hair serum and/or supplement that: Can be used long-term without side effects, Does not contain minoxidil, Is suitable for use in cases where hair fall may be linked to underlying digestive issues,
