Some dudes shit looks fake as fuck and that's where the bullshit comes into play, because it looks like it was painted on or drawn in with eyeliner.
I've been using Bigen on my clients for over 10 years. Most cats use #59 which is jet black. Most folks hair isn't jet black which is why it looks stupid, so I use #58 which is black brown or #57 which is dark brown and I don't leave it in for 30 mins like they recommend. Soon as their beard looks fully saturated I'll wait 5 mins or so and they wash it out, which gives cats a more natural look.
Maybe my perspective is different because I'm a Barber, but women dye their hair all types of colors and I don't see a problem when a man does it because he is greying or just wants a fuller looking beard.
When your beard starts to grey, it comes in patches which in most cases looks stupid as hell and I don't know a brother for wanting to keep his appearance up and keep a more uniformed look.
Women get liposuction, breast implants, ass implants, face lifts and all kinda other things to look youthful and keep themselves looking good and Men get all this flack just for dying their beards or their hair?! That's bullshit!
Unless nigga are getting that Shawty Lo or Boozer look, let these brothers live and keep their self esteem in tact.
