Ruderma for maintenance

Hi there. I’m a beginner to hair loss treatment and had some noob questions regarding Ruderma (apologies in advance if this is obvious stuff and thank you for your time).

I suffer from MPB but it’s at a pretty slow rate - my hairline is receding, but it’s not yet bad. Simply put, I’m at a point where I would be happy if I can retain what I have rather than looking for regrowth.

I am about to go on TRT (prescribed) as my test is low and affecting sex drive. Worried that this will accelerate loss and I want to maintain what I have, so looking into Ruderma. I just had a few questions I hoped the community could help with:

  1. ⁠Is it easy to apply to your scalp?
  2. ⁠Given it hinders the function of DHT, do people notice it reducing libido?
  3. ⁠Should I also use topical minoxidil or is RU sufficient? If using minoxidil, do you apply it before or after the RU?
  4. ⁠Should I also use a 1mm derma roller and, if so, how often should I use it and should it be at the same time as applying RU?
