Shedding after taking Saw Palmetto

[Rizaan]

So I recently got capsules ( just 160 mgsaw palmetto + vitamins) online. Just a day after taking my first capsule, my scalp started to itch from time to time, and now 2 days later I'm shedding heavily. I applied my usual minoxidil in the morning, and after a few hours noticed my scalp was VERY dry. My skin was coming off and when i rubbed my head, I couldn't believe how much dandruff started to get off along with a lot of hair.
I got so scared, i took a shower and used Ketoconazole (2%), and even after that shower when I ran my hand over my head, hair came out which has never happened before. Most of these hairs were thin (miniaturised). Is that of any significance? Does this mean I'm a diffuse thinner + have MPB(I'm a NW1.5)?

I know there isn't much research for Saw palmetto, but it is known to be a DHT blocker and a lot of people use it. I've read from some reviews that there could be some shedding at first but i didn't think it would happen so soon and so much (easily more than 100+ hairs) that too while giving me an itchy, dry scalp; and this was just 160 mg of Saw Palmetto taken orally!
Should i keep taking the supplements and hope to regrow what i lost or should I stop? (please don't tell me to do the later if you dismiss anything aside from the big 3)
