is there any trick for it to not look fake af?

i've never seen successfully coloured beard (or hair for that matter), it always looks cringy.

i've been getting grays but they don't look good on me  

You have a few options:

1. Go to Amazon and look up UST FOR MEN Color Gel Mustache & Beard. There are others, find one that works for you. BTW, you'll need to touch up ever three or four days for it to look natural. No biggie, takes five minutes.

2. You can have it lasered off. There are special lasers that target white/gray hairs. Problem solved. You can either target specific hairs or get rid of it all.

3. Pluck. It's painful but you can get rid of them that way.

Why woyuld you conceal it? It's part of the normal process of getting old and even in some cases it looks nice.

Disease is a normal thing yet we go to the doctors to get better and vaccinate.
Our hair and nails grow long, yet we cut them.
Gaining weight is normal, yet we watch what we eat and maintain a certain weight.
No one is ever born with a tattoo, pierce, or stretched lobe but people do it.

Coloring your facial hair, including eyebrows, can be a normal part of vanity. If you're into, do it – never let anyone tell you that you're obliged to let Mother Nature bitch slap you.

I agree..

Absolutely.  I don't care for the hair dyes with all those chemicals.  So I've used henna.  It creates a much more varied and natural look.  Be careful with dark browns and black as they can give your hair a green tint the first time you use it.  Build up to that colour if you want it.

Is that hair dye made from henna or just the body ink?

When I used to have a full beard, I had a lot of greys, and I used to colour it. The secret is not to just put on beard colour all over and cover every single white. Most beard colouring kits have a brush with it, my advice is use it!!

Basically blend the colour through a bit and/or use a colour slightly less darker than your hair.. the reason is it looks more natural, in my opinion, than just completely covering every grey.

Only exception to this, I would say is if you only have a few greys and you want to cover them, then sure! go for it! The secret is to practice a bit with it, and leave it looking as natural as possible
