You're probably not getting enough mustache hydration.
Here's the deal, folks: your 'stache is like a desert flower in the scorching desert sun. It needs water, man. Drink up!
Drink more coffee.
It's not just for the caffeine, though that's nice. The real reason you should drink more coffee is because it helps keep your mustache from getting brittle and prone to breakage.
Avoid using hairspray on your mustache.
It's like putting diesel in a Ferrari, man. It'll get you there, but it'll ruin the ride.
Use a mustache comb.
It's like a regular comb, but for your mustache! It's got more bristles, man. It's like a party in a comb.
Stay hydrated, mustachio!
