The Biggest Summer Hair Extension Struggles (And How to Fix Them)
1. Hydration is Non-Negotiable
Sun exposure, pool chemicals, and salty ocean water strip moisture from your extensions faster than your iced coffee melts in 90-degree weather. Unlike your natural hair, extensions don’t receive hydration from your scalp’s natural oils, so it’s up to you to keep them nourished.
What to Do:
- Use a gentle yet cleansing shampoo and softening conditioner to rebalance and replenish moisture.
- Apply a lightweight leave-in conditioner (avoid the bonds!) to keep your strands soft.
- Deep condition once a week with a nourishing conditioner or mask to combat dryness.

2. UV Protection for Your Hair
You wouldn’t step outside without SPF on your skin, so why leave your extensions defenseless? UV rays can fade color and weaken the integrity of your extensions.
What to Do:
- Wear a wide-brim hat or a chic scarf when out in the sun.
- Important! When choosing a sunscreen, make sure that you reach for a mineral based one and be sure to avoid Avobenzone, Octocrylene, and Oxybenzone. We recommend using the Coola Mineral Sunscreen!
- Rinse your hair with clean water before swimming, and add some detangler or oil. This helps prevent chlorine and salt from absorbing into your hair.
Pro Tip: If you have blonde hair and extensions, be extra cautious! Sun exposure, self tanner, sunscreens, and pool chemicals can turn them brassy.

3. Saltwater & Chlorine: The Frenemies of Extensions
Chlorine and saltwater can cause tangling, dryness, and in some extreme cases, discoloration.
What to Do:
- Braid your hair before swimming to minimize tangling. Tie off your hair with SOFTWEAR 100% silk hair ties.
- Apply a light leave-in conditioner as a protective barrier before diving in.
- Rinse with fresh water immediately after swimming to prevent buildup.
- Wash with a gentle yet cleansing shampoo to remove any lingering chemicals.
4. Sweat & Oil Buildup
Hot weather means sweat, and sweat means more frequent washes—but overwashing can dry out your extensions. So, how do you keep that fresh, voluminous look without constant shampooing?
What to Do:
- Use dry shampoo at your roots to absorb excess oil (without drying out your ends).
- Opt for low-maintenance summer styles like loose braids, buns, or ponytails to keep your hair off your face and body. Use SOFTWEAR 100% silk hair ties for your summer styling!
- Schedule regular maintenance with your stylist to prevent tangling or slippage.
5. Nighttime Care
Hot nights can lead to tangled, matted extensions by morning, especially if you’re tossing and turning in your sleep.
What to Do:
- Switch to a silk or satin pillowcase to reduce friction.
- Loosely braid your hair before bed to keep it from tangling. Tie off your hair with SOFTWEAR 100% silk hair ties to prevent breakage.
Pro Tip: Avoid sleeping with wet extensions—this can cause matting and breakage. Always let the attachments dry completely before bed!
