Can Sun Damage Cause Hair Loss?

There are many factors that go into the progression of hair loss - genetics, lifestyle, and environment are all aspects that can play a significant role and aren’t necessarily factors you can control.

Sun damage, however, is a major contributing factor to hair loss that you can control. A sunburnt scalp can cause hair loss as it damages the protective oils and cellular structure of your hair and skin. This can trigger the production of a compound called superoxide that may cause hair follicles to switch from the growth phase to the shedding phase, increasing the possibility of extended hair loss.

Is the Sun Good For Your Hair and Scalp?

According to the Cleveland Clinic, sun exposure can damage the outside cover of the hair strand, called the cuticle. You are especially susceptible to hair loss acceleration from the sun if you have lighter or finer hair. Your hair is at even greater risk of sun damage if you frequently lighten your hair, swim in chlorine pools, or use heat on your hair.

That being said, a little bit of sunshine and Vitamin D is good for your hair in small doses. A lack of Vitamin D can actually cause conditions like alopecia. But, as mentioned, too much can cause problems.

Prolonged exposure to the sun can lead to hair damage, dryness, and color fading. It also breaks down proteins in hair, leading to weaker strands. The scalp is sensitive to sunburn, just like the rest of your skin. Prolonged sun exposure causes redness, irritation and even peeling of the scalp.

How to Prevent Sun Damage Hair Loss?

The good news is that there are ways to limit sun damage hair loss. Here are some ways you can limit hair loss because of sun exposure.

Protect your head from direct sun exposure

It’s important to protect your head from direct sun exposure, especially when you go places like the beach in the spring and summer. It’s important to wear a hat or a scarf on your head or use an umbrella to keep the sun’s rays off of you.

Don’t go out in the middle of the day

As tempting as the warm weather is, it’s better to go out earlier and later in the day rather than mid-day. The sun's rays are strongest in the early afternoon, especially during warmer seasons, so it's better for your hair to prevent hair loss if you do most of your adventuring outdoors in the mornings and evenings.

Swim with a cap in chlorinated pools

As previously mentioned, chlorine is also a contributor to hair loss. Swimming in pools that have chlorine, especially outdoor pools with the added sun exposure, can severely damage your hair. It’s better to wear a swimming cap when in chlorinated pools or avoid chlorine altogether by swimming in saltwater pools if possible.

Don’t over shampoo your hair

The oil in your hair is meant as a natural protectant from the sun, so over shampooing and stripping the hair of those oils puts you at a greater risk of hair loss from sun damage.

Trim and condition your hair

Fragile and dry hair is more susceptible to sun damage, and therefore more prone to hair loss. It’s important to keep your ends trimmed to minimize the amount of dry hair, and also condition your hair to strengthen it.

Use sunscreen on your body and your hair

While you’re probably focusing most of your sunscreen on exposed parts of your body, it’s easy to forget to apply it to your scalp as well. There are sunscreens that are specifically meant to be used on your scalp and hair to protect it from sun damage.

Can You Reverse the Effects of Sun-Damaged Hair?

The good news is that even if your hair has fallen victim to sun damage, there are ways to reverse it and get your hair back to being healthy and beautiful. Nevertheless, if your hair is already in the early or late stages of hair loss, it’s important to follow all of the above rules and advice when it comes to hair care in the sun. There are other ways you can help your hair regrow back and better than ever before.

Don’t use as much shampoo

According to Men’s Journal, using too much shampoo can be a factor in hair loss, especially after hair loss and thinning started by sun damage. By cutting down your shampoo usage to half or even a quarter of what you normally use, especially with sun-damaged hair, you can better preserve the natural oils that nourish the hair throughout the day and protect your hair, which would otherwise be stripped away with loads of products like shampoo.

That being said, it is important to regularly condition your hair. You really shouldn’t go for days on end where you aren’t conditioning your hair unless you’re substituting it with a hair mask. Your hair needs moisture and nutrients - the sun and some shampoos will severely strip your hair of natural oils that are essential.

Does Sunlight Cause Gray Hair?

Sunlight itself directly doesn't cause gray hair. However, it can indirectly contribute. Overexposure to the sun can cause premature aging of the skin, specifically gradual loss of melanin which is the pigment responsible for hair color. As we age, the production of melanin decreases, leading to the growth of hair that is lighter in color, which can eventually appear gray or white.

Thicker, coarser, and naturally oily hair can withstand UV radiation exposure better than thinner hair. However, it is best to cover hair if you are exposed to the sun for a long period of time.

How to Protect Dyed Hair From the Sun?

Artificial hair color is more easily damaged by sunlight than natural hair color. That is why it is important to protect dyed hair from the sun to maintain color and overall hair health. To protect your dyed hair, you should cover it up when you are out. Also, look into some hair care products such as sulfate-free shampoos and conditioners as well as hair-specific sunscreen.

Does sun make your hair grow?

Although sunlight does not directly cause hair to grow, its exposure triggers the production of vitamin D in your body, which plays a role in maintaining overall health, including your hair follicles. Additionally, moderate sun exposure can also improve the overall health of your scalp by reducing fungal and bacterial growth.
