Know the Science
Beards are associated with winter warmth, but not for the reason you think. See, while your scruff may keep you toasty by acting as a windshield, it doesn't do much in the way of insulation. That means it won't retain heat during the scorching height of summer. In fact, some beardsmen even claim that their whiskers keep them cool—dissipating heat as the hairs grow damp from sweat—but we can't confirm or deny either way.
Make Cleansing a Priority
Your beard may not act as a woolen scarf, but it can cause irritation when your skin is hot and damp, so it's all the more important to keep it properly cleaned. Scrub it down every morning with a specialized cleanser, like Billy Jealousy Beard Wash: This will remove any grime or debris that might accumulate in your beard, causing inflammation and itchiness.
This may sound a bit like overkill, but a healthy beard starts with a healthy body. Summer is the season of dehydration, which can cause your hairs to grow brittle, and even more prone to breakage. Ensuring that you drink enough water is the easiest way to condition it.
Freshen Up Your Beard Oil
A warm, woodsy oil may be perfect for winter, but if you're rubbing something into your face on a scorching summer morning, you might as well make it refreshing. Try swapping out your beard oil for a lighter, citrus alternative, like Mr. Natty Bring Me Sunshine Frank's Beard Elixir.
If All Else Fails, Give It a Trim
If irritation persists despite your best efforts, it might be time to compromise and give your whiskers a trim—a final length of 1-2 inches should be plenty. This will give your skin more access to airflow, and make it easier to clean, while allowing you to quickly regrow once the season starts to change.
