While most people remember to shield their skin from the hot summer sun, many forget that hair requires similar protection. Unfortunately, prolonged sun exposure damages the hair cuticle, leaving your locks dry, brittle and prone to breakage. Keep reading to learn how solar radiation affects your hair and how adding protective measures to your hair care routine safeguards your locks from damaging UV rays.
Understanding Sun Damage to Hair
The sun emits ultraviolet (UV) rays that break down protein bonds within the cuticle, which serves as the protective outer layer of each strand. When this layer becomes damaged, hair loses moisture, resulting in dryness, discoloration and split ends.
Color-treated hair faces additional challenges because UV rays fade artificial pigments faster than natural ones. That is why highlighted or colored hair often appears brassy or dull after extended sun exposure.
Signs Your Hair Has Sun Damage
Recognizing sun damage early allows for faster intervention. Watch for increased brittleness, roughness when you run your fingers through your hair and color fading that appears as unwanted brassy or orange tones in brunettes and ashiness in blondes.
Split ends multiply faster with sun exposure, climbing higher up the hair shaft than usual. Your hair may also lose its shine, appearing dull even after washing. Texture changes often occur, too, with straight hair becoming frizzy or curly hair losing its defined pattern.
These symptoms appear gradually, making them easy to miss until significant damage has occurred. Regularly assessing your hair’s condition, especially during summer, is the best way to catch problems early.
Protective Measures Before Sun Exposure
Prevention works better than repair when dealing with sun damage. Before heading outdoors, apply a UV-protective hair product to block harmful rays.
Wearing a hat provides physical protection that no product can match. Wide-brimmed styles offer the most complete coverage for hair and scalp, preventing direct exposure to damaging rays. If you do not like hats, a scarf or bandana tied around your head offers similar protection.
The sun is usually at its brightest (and most damaging) between 10 a.m. and 4 p.m. Plan outdoor adventures during morning or evening hours when possible to minimize damage.
The Benefits of Hair Oiling for Sun Protection
Hair oiling, an ancient technique practiced across many cultures, provides excellent protection against sun damage. Applying natural oils creates a barrier between your strands and environmental stressors while nourishing from within.
Coconut oil is excellent for sun protection because it contains lauric acid, which binds to hair proteins and prevents protein loss. Plus, its molecular structure helps it penetrate the hair shaft rather than sitting on the surface.

Argan oil contains high levels of vitamin E. This natural antioxidant fights free radical damage caused by UV exposure. Regular application before sun exposure helps maintain moisture balance and prevents brittleness.
To experience the full benefits of hair oiling, apply oil to clean, damp hair at least 30 minutes before heading outside. Focus on mid-lengths and ends where damage occurs most frequently. This pre-sun ritual creates an invisible shield that reduces UV penetration while simultaneously conditioning your strands.
Special Care During Swimming
Swimming increases the risk of sun damage because water reflects UV rays, intensifying their effect. And wet hair absorbs more solar radiation than dry hair, making protection even more important.
Before taking a dip, rinse your hair with clean, fresh water. Hair absorbs what it encounters first, so saturating your strands with clean water reduces chlorine or salt absorption. After rinsing, apply a leave-in conditioner with UV protection.
Swim caps provide excellent protection for regular swimmers. Modern silicone versions cause less friction than older latex styles, preventing breakage while keeping hair dry and protected from chemicals and sun exposure.
How to Treat Damaged Hair After Sun Exposure
Give your hair some TLC immediately after sun exposure to minimize the damage. Start with a gentle cleansing using a sulfate-free shampoo that removes product buildup and environmental residue without drying your hair.
Deep conditioning treatments are essential after sun exposure. Products containing keratin help rebuild protein structures damaged by UV rays. Masks with shea butter or avocado oil restore moisture balance and improve elasticity in brittle strands.
Consider overnight treatments for severe damage. Apply a generous amount of a conditioning mask or oil blend to damp hair, cover with a shower cap and leave overnight.
