7 Loc-Friendly Habits to Keep Your Hair Healthy in the Summer Heat
By the Locsanity Hair Care Experts | July 2025
Summer is the season of sun, beach excursions, and endless outdoor adventures. But for those with locs or coily, Afro-textured hair, it can also mean dryness, buildup, and frizz, if you’re not careful. Whether you’ve been growing your locs for years, or are just starting your natural hair journey, summer requires a few key shifts in how you care for your crown.
Here’s your go-to guide to keeping your locs nourished, clean, and thriving all season long, backed by real insight, not just product hype.
1. Prioritize Daily Moisture, Especially in Heat
Summer heat can be especially harsh on coily hair, often stripping it of much-needed moisture and leaving locs feeling dry, brittle, or frizzy. That’s why daily hydration isn’t just a nice-to-have during these months—it’s a must.
Incorporating a lightweight mist into your routine can help restore balance, especially one that blends plant-based ingredients like citrus oils and antioxidant-rich extracts. These kinds of formulas not only refresh your scalp but also strengthen your strands and reduce frizz, without leaving behind itchybuildup.
Whether your locs are freshly started or fully matured, a water-based spray used daily can go a long way in keeping them soft, strong, and well-formed—no matter how hot or humid it gets.

2. Understand the Sweat Equation
Can sweat and humidity damage my locs? Sweat and humidity won’t damage your locs directly, but they can create the perfect conditions for dryness, frizz, and buildup, especially if salt and debris are left sitting on your scalp for too long. That buildup can dull your locs and lead to irritation, or even odor, over time.
To counteract this, try working a few drops of a lightweight oil into your scalp after you’ve washed the sweat and debris out of your hair. Oils that mimic your natural sebum, such as jojoba oil, help keep your scalp balanced and hydrated without clogging pores or leaving residue behind.
It’s a simple step that goes a long way in keeping your locs nourished, especially during hot or humid months.
3. Cleanse More Often, But Gently
Summer activities often mean more sweat, sunscreen, and outdoor exposure, which can lead to buildup on both your scalp and locs. Washing more frequently during the warmer months is totally fine, as long as you’re using a gentle, moisturizing cleanser that won’t strip your hair.
Look for sulfate-free shampoos with plant-based ingredients that cleanse without drying. Focus your wash on the scalp first, massaging with your fingertips to loosen dirt and sweat. Then, gently work the lather through your locs from root to tip, squeezing each loc to lift out buildup.
A thorough rinse is key. Depending on your hair’s needs, you might wash once a week, or more often if you’re swimming, sweating, or in humid conditions.
4. Switch Up Your Routine for the Season
Just like your wardrobe changes in the summer, your loc care routine should, too. Higher temperatures, sweat, and prolonged sun exposure can dry out both your scalp and your strands, making your hair more prone to frizz, breakage, and buildup.
One of the easiest seasonal swaps? Add a lightweight daily mist or spray to your routine. These are typically designed to deliver moisture without buildup, helping refresh your scalp and maintain softness throughout the day.
It’s especially helpful for those with dry or mature locs, where consistent hydration is crucial for maintaining strong, smooth, and healthy hair in the heat. A few spritzes each morning or after sun exposure can make a significant difference in how your locs feel throughout the summer.
5. Shield Your Locs Before You Swim
Whether you're hitting the pool or enjoying a beach day, chlorine and saltwater can quickly strip moisture from your locs, leaving them dry, brittle, or prone to buildup over time. Protective steps before a swim can make all the difference.
One of the most effective ways to guard your hair is by covering it. A well-fitting swim cap designed for locs, braids, or other voluminous styles can help minimize direct water exposure. Unlike standard caps that may tug or leave hair exposed, look for options that are made from flexible, waterproof materials and offer enough room to comfortably fit your style, especially if your locs are long or thick.
If full coverage isn’t an option, consider pre-soaking your locs in fresh water and applying a light oil to create a barrier before swimming. Either way, rinse and cleanse your hair as soon as possible after a dip to remove any lingering chemicals or salt.
6. Choose Low-Friction Styles to Beat the Heat
Hot weather can make wearing your locs in a free fall state feel heavy or uncomfortable, especially during outdoor activities or travel. That’s why summer is the perfect time to lean into updos, buns, and half-up styles that keep your hair off your neck and reduce friction.
If you’re craving a style switch-up—without committing to heat styling or starting from scratch—dreadlock extensions are a great option. They can add length or volume while still blending seamlessly with your natural locs, giving you the flexibility to experiment with protective styles like braided crowns, jumbo buns, or faux hawks.
Extensions allow you to change your look without compromising your hair health. Just ensure they’re installed properly to avoid unnecessary tension on the scalp.
7. Deep Detox to Refresh Your Locs This Summer
Summer fun comes with extra exposure to sweat, sunscreen, saltwater, and more. And while regular washing helps, these elements can still sneak deep into your locs, causing buildup that leaves them feeling heavy, itchy, or dull.
That’s when a seasonal deep detox can make all the difference. Unlike everyday shampooing, a detox treatment targets the inner layers of your locs, drawing out lingering residue that surface-level shampoos might miss. Think of it as a fresh start for your hair, especially if you’ve been swimming, traveling, or using more styling products in the heat. A quality detox will always surprise the most faithful of hair washers. Very rarely does the water left over after a good detox appear clear.
A mid-summer detox can help your locs feel lighter, look more vibrant, and better absorb moisture, so you can keep thriving through every sunny adventure.
