Never seen the first one you linked, may have to consider it since I am vegan.
OP, here is one I’ve come across as well, Hair Restoration Laboratories’ Professional Strength DHT-Blocking Hair Restore Shampoo

Reviews on it are pretty good. I have not tried it yet, waiting to finish my current keto shampoo then buying this one.
