Plenty of info on this site about fin and its side effects. Plenty of people who get off it almost immidiatly because of them. I am crossing my fingers. Nothing crazy has happened to me so far. Hair is odd, what works for some doesn't for others so in that regards you have to try everything to find out. As for Ds labs (spectral), you can use both if you would like, they actually sell a minox product on the site.They also warn about hair fall which also happens with minox. I am on month 5 with the switch.
I can only tell you what I do and show you how it works/doesnt work. The rest is up to you.
