Thanks for the article with great info. I’ve been taking minoxidil 5% for the last 2 years. I’ve tried a generic minoxidil brand and also Kirkland to no effect. I’ve been hoping it’s maybe slowed the hair loss process. The hair around my crown just keeps getting thinner. Do you think changing to another “better quality” brand like Lipogaine or Rogaine could work? Or does it appear that any minoxidil brand is not going to work?
