Hey Zoso,

Welcome to the board!

Firstly, you have everything necessary to rock an awesome beard....great coverage, colour, density and texture. There are lots of guys with awesome curly beards on the board.....if you go into the short beards section and page through until you find Remsio and SNAPPYJB's threads, those are two good examples. As you said, your stache looks very strong; I would try to let it go, unless that gets way too annoying. Check out the 'taming the wild stache' thread in my signature below.

For your other questions:

Your neckline looks good to me; it should be about 1cm above your Adam's apple, or a little lower.

I have not had a problem with bearddruff or split ends...I will let someone else chime in on this. Are you using a beard oil such as argan or jojoba? How often are you washing your beard? Frequently washing with harsh shampoos or soaps can strip away protective oils which need to be replaced. I only use a shampoo or conditioner one every couple of weeks or so and apply a few drops of oil daily.

I look forward to watching your progress!
