Fun in the Sun: The 7 Best Ways to Prevent Hair Sun Damage


Before stepping out into the summer sun, you likely lather up with sunscreen to protect your skin. But have you ever thought about how to protect your hair from sun damage?

That’s right – just like the sun can wreak havoc on your skin, those rays can have a damaging effect on your hair. And if you don’t take preventative measures, you might find yourself with broken, split ends that need to be trimmed off sooner than you’d like.

If you want to maintain shiny, healthy strands while enjoying the sun this season, try these stylist-recommended tips on how to protect your hair from sun damage.

Does Sun Damage Hair?

Want the short answer? Yes, the sun damages hair.

But to help you understand why it has those effects — and how important it is to prevent hair sun damage — here are the details. UVA and UVB rays from the sun can damage your color and style in several different ways:

  • Lipid damage: Prolonged sun exposure can break down your hair’s outer layer of lipids, which act as natural protection from environmental elements. This is one of the major causes of dry hair and frizzy strands, because without this layer, your hair isn’t able to retain moisture.
  • Internal damage: The sun can also damage the internal structure of your hair, weakening it and making it prone to breakage and split ends.
  • Color damage: If your hair is dyed, it’s even more susceptible to internal and external damage, since color treatments can leave your hair dehydrated and vulnerable. Dry hair tends to be more porous, which means dye is more easily washed out. Plus, UV rays act like bleach on your strands, breaking down color and making them fade or go brassy faster than usual.

Who’s Most at Risk for Hair Sun Damage?

Fine or light-colored hair is especially vulnerable to sun damage, while thicker textures and darker shades offer more natural protection. However, all hair types and colors are susceptible to some level of sun-damaged hair.

Location doesn’t provide much protection either. Whether you’re spending time outdoors in the suburbs or relaxing at the beach, your hair remains at risk for sun damage.

With ozone depletion and the increasing intensity of the sun’s rays, the likelihood of damage continues to grow. To maintain healthy strands, it’s essential to learn how to protect hair from sun exposure now.

Signs of Sun Damaged Hair

If you’re out in the sun for long periods of time, you may start to notice changes to your color and style. Signs of hair damage from the sun include:

  • Discoloration: A dramatic color change is a telltale sign that UV rays have reacted with the melanin in your hair.
  • Change in texture: You may find your once-smooth hair is now dry, rough, and brittle and doesn’t swing freely like it used to.
  • Split ends: As the sun penetrates your hair, your strands become more fragile and prone to breakage.
  • Quicker drying time: Hair that dries unusually fast after washing may indicate increased porosity, a result of sun-damaged cuticles that can no longer retain moisture effectively.

How to Protect Your Hair from Sun Damage

Just like you use SPF on a daily basis, there are several things you can do to protect your hair before heading out into the sun.

Add a Barrier

An easy way for how to protect hair from sun naturally is to use a physical barrier, like a scarf or hat. Be aware, however, that not all hats are created equal when it comes to hair sun protection. Hats rated with an ultraviolet protection factor (UPF) number are your best bet to minimize hair sun exposure, since they’re tested and regulated by the FDA. Otherwise, choose a tightly woven fabric over an open weave straw hat, which can let in harmful rays.

Minimize Peak Sunlight Exposure

To avoid getting sunburned, it’s best to steer clear of sun exposure during the hottest part of the day — and the same goes for protecting your hair. If you plan to be outside, aim for the morning or late afternoon. While you won’t totally escape the sun, you will avoid some of the harshest and most damaging rays.

Add SPF to Your Hair Care Routine

You already buy sunscreen for your skin, so consider adding an SPF product designed for your head to your routine. Whether you choose a spray or powder-based shield, there are plenty of options for protecting your hair.

Keep Your Scalp Healthy

To some extent, your hair protects your scalp from the sun — but not completely. And in fact, because your scalp isn’t used to getting much direct sunlight, it can be extra sensitive and fragile. Too much sun on your scalp can cause sunburn and dryness, which can then affect the roots of your hair. Make sure to apply SPF to your part and moisturize regularly (more on that later) to keep your scalp in optimal condition.

Avoid Chemicals

In the summer, the sun and the pool often go hand in hand, but chemicals like chlorine can weaken your hair, making it even more prone to sun damage. The same goes for the chemicals used in lightening treatments — they make your hair weak and vulnerable to the sun’s harsh rays. That doesn’t mean you have to give up a sun-kissed look for summer, but for maximum protection, it may be worth forgoing color treatments involving bleach.

Take a Break From Heat Styling

The sun is brutal enough on its own. Adding heat styling will only multiply the damage. While you don’t have to pack away your blow dryers and curling irons for good, using them less often during the summer can help keep your hair strong. To give your strands a break, a styling cream like Hair Balm can help you achieve a frizz-free, air-dried style.

Of course, you’ll still want a blown-out, straightened, or curled look every once in a while. So when you do pull out your hot tools, make sure to use a heat protectant, like Dressed Up, to guard against heat and UV light.

Make Extra Effort to Moisturize

One of the prominent signs of hair sun damage is dryness — so to protect hair from sun damage, you’ll want to have a solid moisturizing routine. But don’t just buy the biggest bottle of conditioner you can find. In fact, if you swap out your traditional shampoo for a soap-free alternative, you’ll find you don’t need a separate conditioner at all.

Here’s why: Conventional shampoo strips away the hair’s natural oils, and then a conditioner replaces that moisture. But you can avoid removing those oils in the first place — by using a soap-free cleanser, like New Wash — and keep your natural moisture and protective barrier. You can also add in extra hydration with a leave-in conditioner, like Hair Balm.

It Comes Down to Proper Protection

The sun can present a persistent challenge for your hair, but it doesn’t have to cause lasting harm. By learning how to protect your hair from sun exposure—such as wearing a protective hat, incorporating SPF hair products, and maintaining a strong moisturizing routine—you can prevent sun-damaged hair and keep your strands vibrant and healthy.

Don’t wait for the signs of damage to appear. Start making small changes today, like swapping harsh shampoos for a soap-free cleanser or minimizing peak sunlight exposure. These simple yet impactful steps will allow you to enjoy your time in the sun without sacrificing your hair’s health or shine.

Your hair deserves the same care and attention as your skin. With the right approach, you can soak up the sun and still keep your hair looking and feeling its best.

Frequently Asked Questions

  • Does the sun damage your hair?
    Yes, the sun damages hair. UVA and UVB rays break down your hair's outer layer of lipids, causing dryness and frizz by reducing moisture retention. Sun exposure also weakens the internal structure of hair, making it prone to breakage and split ends. Color-treated hair is especially vulnerable, as UV rays act like bleach and cause dye to fade or go brassy faster than usual.
  • Who is most at risk for hair sun damage?
    Fine or light-colored hair is especially vulnerable to sun damage, while thicker textures and darker shades offer more natural protection. That said, all hair types and colors are susceptible. Location doesn't provide protection either — whether you're in the suburbs or at the beach, your hair is at risk from UV exposure.
  • What are the signs of sun-damaged hair?
    Signs of sun-damaged hair include discoloration from UV rays reacting with hair melanin, a change in texture leaving hair dry, rough, and brittle, and increased split ends as strands become fragile. Hair that dries unusually fast after washing may also indicate increased porosity caused by sun-damaged cuticles that can no longer retain moisture effectively.
  • What type of hat best protects hair from the sun?
    Hats with a UPF (ultraviolet protection factor) rating offer the best protection, as they are tested and regulated for UV coverage. If a UPF-rated hat isn't available, choose tightly woven fabric over open-weave straw hats, which can let harmful rays through and offer little actual protection.
  • Should I use an SPF product on my hair?
    Yes — adding an SPF product designed specifically for hair is a highly recommended step before going outdoors. Available in spray or powder form, these products shield your strands from UV damage much the way sunscreen protects your skin. Applying SPF to your part line also helps protect a sensitive scalp from sunburn.
  • Can sun damage affect color-treated hair differently?
    Color-treated hair is more susceptible to sun damage because chemical treatments leave hair dehydrated and porous. UV rays act like bleach, breaking down color molecules and causing dye to fade or go brassy faster than usual. Using a soap-free cleanser like New Wash helps preserve your color by cleaning without stripping your hair's natural protective oils.
  • What is the best way to keep hair moisturized and protected from sun damage?
    Swapping traditional shampoo for a soap-free cleanser like New Wash is one of the most effective steps — it cleans without stripping your hair's natural oils and conditions at the same time. Adding Hair Balm as a leave-in provides extra hydration and helps you achieve a frizz-free, air-dried style. Together, they help maintain the moisture barrier that sun exposure works to break down.
  • Should I avoid heat styling in the summer to protect my hair from sun damage?
    Reducing heat styling in summer can help minimize compounded damage, since heat and UV exposure together are especially harsh on strands. When you do use hot tools, apply Dressed Up to damp hair beforehand — it guards against both heat and UV light while adding soft hold. On days you skip heat, Hair Balm can help you achieve a smooth, air-dried look.
