29M Massive density loss in just 18 days while on Finasteride and Minoxidil for years. I'm desperate

Hi everyone’,

I am 29 and I’m looking for some opinions because I’m honestly feeling very depressed and hopeless right now.

I’ve been taking Finasteride daily for 3 years and using topical Minoxidil for 4 years.

I’ve been very consistent with Finasteride and the treatment had been working extremely well for about 1.5 years. My hair density was the best it had been in years, and everything seemed stable until late May / early June.

However, since the beginning of June, I’ve experienced what feels like a massive loss of density in just a few weeks.

The first photo was taken on June 3rd, 2026 and the second one was taken today (June 21st, 2026).

That’s only 18 days apart, yet my hair looks dramatically thinner.

And just to be clear: I did NOT cut my hair on top at all. The visible difference is only due to hair loss, not a haircut. I’ve simply lost a lot of hair and curls over the past 2–3 weeks.

I have curly hair but it is realy worse when it is wet.

A few things that may or may not be relevant:

I switched to a different Minoxidil brand in February 2026.

I switched to a different Finasteride brand in March 2026.

I know the active ingredients are supposed to be identical, so in theory this shouldn’t matter, but I’m starting to have doubts.

The treatments had been working very well before all of this happened.

I’m still shedding hairs every day and my density seems to keep getting worse.

Do you think this could be:

A shed caused by changing brands ?

A delayed Minoxidil-related shed ?

Telogen effluvium ?

Seasonal shedding ?

Or is this simply androgenetic alopecia progressing despite treatment ?

One thing worth mentioning is that I may have been slightly less consistent with Minoxidil over the past few months, but I was still using it every single day, and on average twice daily about 5 days out of 7 each week. I wasn’t stopping treatment or taking long breaks.

Because of that, I don’t really think this level of density loss can be explained solely by my Minoxidil usage, but I’m mentioning it for completeness in case anyone has had a similar experience.

Has anyone experienced such a rapid drop in density while remaining on Finasteride and Minoxidil ?

I’m genuinely struggling mentally with this because it happened so fast after a long period of stability, and I feel like I’ve lost a huge amount of progress in only a few weeks and it is getting worse day by day.

Any thoughts or similar experiences would be greatly appreciated.

Thank you.
