Why your hair needs sunscreen

Have you ever wondered why your hair is dry and damaged, even after using a top-quality shampoo and conditioner? There are many factors that can dull your hair, and one of the most common is excessive sun exposure. Chemically treated hair is even more fragile and prone to sun damage and split ends.


So how does sun exposure damage your hair?

When you go outdoors, ultraviolet (UV) rays pierce through the outermost layer of your hair shaft, which is called the cuticle, and produce free radicals. Then the damage begins.

If you’ve coloured your hair and spend a lot of time under the sun, you may wonder why your hair looks brassy after a while. Hair colour often changes when it’s exposed to excessive UVA radiation. People with naturally dark hair are fortunate, because the pigment that gives the hair its dark tones melanin €”also gives it natural sun protection. Those with fair hair are likely to see damage earlier because of less melanin.

UVA radiation affects your hair less than UVB radiation. The latter attacks hair proteins, such as keratin, that make up most of the hair shaft. UVB radiation can cause more severe damage in the form of breakage and dull hair.

If there’s any good side to solar hair damage, it’s that unlike skin damage, hair damage won’t affect your health. Sun-damaged skin can lead to skin cancer. Hair itself is not alive, so its cells cannot be adversely affected. The living hair roots and follicles are under the scalp, which is protected by the hair. If the hair shaft itself becomes damaged, it will be replaced by new growth. But because hair is a huge part of our appearance, hair damage is very prominent to everyone.

If your crowning glory is dry and dull, you’€™ll have more bad hair days. The good news is that you can protect you hair and make it as healthy as possible, in the same way you can improve your skin with good care. Sometimes, shampoos and conditioners are not enough to take care of your tresses. Weekly hair masks are great way to restore the beauty of your locks. But hair sunscreens can actually protect your hair from the potential damage caused by harmful UV rays!

If you haven’€™t heard about hair sunscreens, it’€™s time that you did. Hair sunscreens may not be as popular as face and body sunblock products, but they’re just as important. Hair sunscreens can help protect the hair shaft by filtering UV rays, and they may even help repair damaged hair. No matter what the season, hair sunscreen is a must-have for everyone. In summer, hair is more prone to dryness and damage because of too much heat and humidity. Whether you’€™re at the beach or just strolling around the park, there’€™s a sunscreen made especially to target your needs.



Here are different hair sunscreen types you can choose from:

Dual-purpose skin and hair sunscreen spray to protect your hair and skin
Sun shield conditioning spray for a vibrant and silky shine
Weekly conditioning hair mask with sunscreen to maintain beautiful hair color and protect it from fading
Intensive hair and scalp treatment with SPF to repair hair from roots to tips and protect it from harmful UV rays
Hydrating sun protection spray that moisturizes and protects for healthy-looking hair
Water-resistant UV protection hair fluid to protect your hair even at the beach or pool
Protective beach hair spray to prevent hair dryness caused by the sun during sunbathing or any outdoor activities at the beach.
Long-lasting sun care protection spray to prevent hair damage if you stay under the sun all day

Some shampoos, conditioners, and hair oils contain sunscreen, so if you know you’€™ll be staying outside much of the time, you can incorporate different products into your usual haircare routine. But hair sunscreen is not the only way to protect your hair from the damaging effects of the sun.

Another option is to wear a hat €”especially a wide-brimmed one to protect your hair and face from sunburn. A scarf is another great hair protector. If you don’€™t like wearing anything on your head, always remember to apply regular sunscreen to the exposed areas of your scalp, such as your part. If you often wear your hair up, apply sunblock to the back of your neck and behind your ears, too, as these spots are often neglected and end up getting burned.

Excessive hair dryness can be corrected by moisturising your hair with natural oils and applying a hydrating sunscreen to prevent further damage. Make it a daily habit to use hair sunscreen. Never step out in the sun without protecting both your skin and your hair.

If you’€™ve ever wondered why your hair feels dry and looks dull after you go swimming, it’€™s because hair is weaker when wet and more prone to damage. Always rinse your hair with clean water after taking a dip, as salt and chlorine can discolour hair. A great tip is to wind your hair into a bun and then spray sunscreen over your head. Rinse your hair every time you come out of the water, and add more sunscreen.
