Dr. Groot Microbiome Genesic 7

I have a dry scalp and am worried about dandruff and hair loss, so I am trying out various products.

I am using it because I heard it is effective for dandruff and even hair loss.

I heard it has the highest repurchase rate, but honestly, I'm not sure if it's effective yet.

Free from 20 ingredients including sulfate-based surfactants and silicones, and German Dermatest

Since it has received an Excellent rating, I think I should trust it and use it a bit more.
