Start of the journey

Just as the title says, I‘ve started my minoxidil journey. I’m 28 years old and can grow a decent beard, but there’s a couple of areas I’d like to be fuller. My cheeks and chin (soul patch area) mostly. I only started growing my beard a year ago and I keep it at a length that hides the less full areas. It’s always well maintained as I get my hair cut and beard trimmed every week. I also get my barber to fade the beard on my cheeks which helps hide the fact that I don’t have full coverage on my cheeks (see 2nd picture).

I’ll be using the regaine foam twice a day and moisturising with cerave since I’m prone to dry skin. Not gonna bother with derma-rolling.

Question though; from what I’ve read, cerave is a good moisturiser to use as it doesn’t have any DHT blocking ingredients. However, do I also need to be using products which don’t block DHT on the rest of my face, and for washing my hair? Or do I just need to make sure the moisturiser I use for my beard doesn’t block DHT?

The reason I ask is cause I use a different moisturiser for the rest of my face, cerave leaves my skin quite oily.
