How to Protect Your Hair from the Sun
Rising temperatures, salt water and long days outdoors can all take a toll on hair, whether you're by the pool, at the beach or just soaking up a sunny afternoon. Knowing how to protect your hair from the sun means understanding what's actually happening to your strands, then building a few simple habits into your routine before the damage sets in.
Does the Sun Damage Your Hair?
Does the Sun Bleach Your Hair?
It can. UV rays break down melanin, the pigment responsible for hair's natural color, which is why hair often looks lighter after a summer outdoors. This lightening effect isn't limited to natural color either. Sun exposure can fade color-treated hair too, pulling warmth or brightness out of a fresh dye job faster than it would fade indoors.
Does the Sun Help Your Hair Grow Faster?
Not directly. There's no evidence that UV exposure speeds up the hair growth cycle itself. What sunlight can do is support vitamin D production to avoid deficiency, and vitamin D plays a role in keeping hair follicles healthy, but that's a long way from sun exposure making hair "grow faster." Too much sun tends to work against healthy-looking hair rather than for it, since the breakage and dryness it causes make hair look thinner and more worn down over time.
How to Protect Hair from the Sun
Start With a Clean Scalp
Heat and humidity mean more sebum, and that oil combines with sweat to leave hair feeling heavier and greasier than usual. Rather than reaching for dry shampoo every day, a weekly scalp treatment works better. Cleansing Purifying Scrub with Sea Salt uses sea salt crystals to gently exfoliate the scalp, while a natural carbohydrate complex helps support its natural defenses against dehydration. A tablespoon is all you need per wash, which makes one jar last through multiple trips. For more scalp care tips, see our healthy scalp guide.

The drier your hair is, the more vulnerable it is to sun damage, so this is the time to double down on moisture. Hydrating Melting Mask with Aloe Vera is a lightweight option that melts into hair for an instant boost of shine and softness. For hair that's already dry, damaged or chemically treated, Regenerating Mask with Prickly Pear Oil is a richer, creamier treatment that nourishes and revitalizes in just five minutes, leaving strands supple and less prone to frizz.
Seal in Protection Before You Step Out
$39.00
A leave-in product with heat protection doubles as a shield against everyday styling tools and time spent under the sun. Regenerating Serum with Prickly Pear Oil protects against artificial heat up to 230°C (440°F) and helps smooth the look of split ends and frizz along the way. Apply it before heading outside, and reapply after a swim once hair is dry.

If your color is at risk of fading in the sun, Colour Shield Cleansing Mask with Camu-Camu Berries helps protect natural color while nourishing hair, making it a good once-a-week swap for your usual shampoo during sunnier months.
Embrace Your Natural Texture
$39.00
Cutting back on hot tools is one of the simplest ways to reduce the total heat and sun exposure your hair takes on in a day. If your hair is fine or flat, Cleansing Volumizing Paste with Rose Extracts boosts lift and body at the roots without any styling tools involved, and Instant Volumizing Leave-In Mist with Rose Water keeps that texture going between washes on damp or dry hair.

Choose the Right Brush
$65.00
Sun and humidity can leave strands weaker and more brittle, so how you brush matters as much as what you apply. A natural boar-bristle brush, like our Travel Hairbrush, offers gentle detangling that lowers the risk of extra breakage while distributing natural oils from root to tip.
A Simple Sun Protection Routine
Weekly : Cleansing Purifying Scrub with Sea Salt, to clear oil and product build-up from heat and sweat.After washing : Hydrating Melting Mask or Regenerating Mask with Prickly Pear Oil, depending on how dry or damaged your hair is feeling.Before you go outside : Regenerating Serum with Prickly Pear Oil, to shield hair from heat and help lock in shine.If your hair is color-treated : Colour Shield Cleansing Mask, once a week to help protect natural color from fading.On the go : Travel Hairbrush, for gentle detangling wherever your day takes you.
The Takeaway
The sun can dry hair out, fade its color and wear down the cuticle over time, but none of that has to be inevitable. A clean scalp, consistent hydration and a heat-protecting serum before you head outdoors will keep hair feeling and looking healthier long after summer ends.
