Hey bro,
I took a look under the options for Norway and it looks like you can get all the same stuff we can here in the US so that's good.
I think retin-A definitely adds to the protocol, as I seems to regrow more hair faster when its in there. At night,I'll apply the 2% spiro , and then an hour or so later apply the Retin-A (.025 % solution in the dabber bottle) and the immediately after that apply the 12.5 % Minoxidil solution.
One thing to mention, since Ive gone from 15% Xandrox during the day and 5% Minox/Retin-A at night to 12.5% Minox 1x per day, Ive seen an increase in shedding.
This can either be a really good sign - that the increase in minoxidil hitting the scalp is causing a new growth phase. Or it can be a bad sign - dropping the Azelaic acid during the day is causing an increase of DHT in the scalp and causing hair to fall out. I really hope its the latter!
Either of those laser brushes you linked to will do the job. The important thing is the 650nm wavelength diodes putting out around 3 - 5mW. That's what seems to have a positive effect on hair growth.
