2024 Buying Guide: The Best 3 Hair Sunscreens

August 31, 2021 (updated May 22, 2024) — Written by

We know that sunscreen is essential for skin, but what about sunscreen for our hair? Does hair really need to be protected from UV too? Turns out the answer is YES! We dig into the benefits of using hair sunscreen, plus we list 3 hair sunscreen products we recommend and why (regardless of hair color!)

I wouldn’t call hair SPF a daily necessity but for days when your strands will be exposed to the beating sun for hours on end…it has its perks.


Why you should consider hair SPF for your strands

I first started looking into the validity of UV protection spray for hair or hair SPF because summer was approaching and I wanted to keep my gray hair from yellowing in the sun. Gray hair turns yellow or brassy for a myriad of reasons, including exposure to ingredients like EDTA in hair products, environmental pollutants (like cigarette smoke and exhaust), heat exposure, medicine and of course, UV exposure.  

Molecular Biologist and Cosmetic Chemist Kate Noonan explains that hair is made up of 95% keratin protein. When hair is exposed to UV, it breaks down that keratin—specifically the part that gives hair its strength and shine. UV also fades hair color and can create hair-yellowing [1]. 

The kicker is, this applies to all hair colors, although some hair colors are hit harder than others. 

Lighter and warmer hair colors (including gray hair) are more affected, while darker hair colors are not as affected. This is due to hair color’s pheomelanin content and lack of protective eumelanin. 

Black hair, for example, has the more protective ‘black eumelanin’ and loses two-thirds less keratin than brown hair [4].  

Light hair, on the other hand, contains something called pheomelanin. Kate explains that pheomelanin is a phototoxic melanin highest in red, blonde and warm brown hair that increases UV damage [5].

And if you think you’ve got it made because you color your hair…think again. UV also affects those with color treated hair. Says Kate, “Dye molecules slightly screen UV but these fade faster than natural color and leave brassy tones.”

The takeaway? Everyone with hair, regardless of hair color, can benefit from UV protection for their hair. 

(And while we are at it, another way to counteract hair brassiness that happens in blonde and gray hair is by using a purple shampoo. More on why plus the ones we recommend here.)

What to look for in a hair SPF 

This was a bit of a sticking point for team TNK because when we talk about SPF, we advocate for choosing mineral blockers, like zinc and titanium dioxide, over chemical blockers like oxybenzone and octinoxate. But I haven’t met many people who are psyched to lube up their hair with white zinc…so if we are taking zinc off the table, that leaves us with a couple options. 

We can talk about the “best of the worst” when it comes to chemical blockers and we can also look at plants that deliver antioxidants and block UV. Let’s zoom in on the latter.

Plants that block UV

One way to counter the lack of protective eumelanin, Kate says, is to use products rich in UV-blocking plant extracts to keep hair strong and glossy, which is supported in dermatology research [2,3,6,7].

As consumers we’ve seen messaging around plants providing UV protection, but since the FDA does not recognize plants as SPF (and SPF is an FDA regulated product), companies can’t claim specifics on their websites or on labels. 

But the truth is, hair products with plant extracts that block UVB and UVA and neutralize radicals protect hair health and color [2,3]. We see the power of botanical ingredients in this Daud et al. study, which found that aloe vera screened UV when hair was exposed to 4 hours of UV a day for 25 days [8].

So with all of this in mind, we asked Kate to look into the specifics around plants and what they can actually do when it comes to blocking UV because we wanted to know more. Here’s the breakdown:

A colorful graph representing the about of SPR value botanical extracts contain.
a dot graph shows the percentage of UV rays blocked at given SPF values.
A line graph depicts how botanical extracts like mango and rose compare to octocrylene in UVA and UVB blocking abilities.

Graphics by Kate Noonan. A note from Kate: SPF of these plants was determined with the same protocols used to evaluate the UVB and UVA blocking og FDA regulated sunscreens, the FDA in vitro method and ISO method. Their antioxidant activity was measured with the standard assays—ORAC, HORAC, DPPH, Folin-Ciocalteu, FRAP and Oyaizu.

A couple of X factors here, as always 😜. 

Of course, ingredient percentages play a huge role in effectiveness. Most of the time brands won’t disclose this proprietary information—that’s standard. But what we can take away from this list is that even low percentages of ingredients like mango, passion flower and green tea have pretty significant SPF values.

Another X factor (*pushes glasses up on bridge of nose*) is the “globule diameter” or the droplet size of the ingredient. This plays a part in effectiveness too. Kate explains, “when hair sunscreens are a fine emulsion formula, the smaller globules boost SPF by improved UV reflection/scattering (Mie scattering), and the UV-blocking plant extracts have improved photostability in the globules” [1822].

As a consumer, one clue you can use to determine droplet size is to look for plant emulsifiers like baobab seed, galactoarabinan, guar, xanthan gum or caprylyl/capryl glucoside on the label. These ingredients indicate the formula is a microemulsion, meaning all of the smaller droplets contain the active plant extracts.   

Lastly, application is also an X factor…can you really coat every strand evenly and are you willing to reapply as needed? All of this to say, we are taking ballpark figures with a lot of variables. But what I want you to take away from this section is: When we look at the question, Can plants be effective in protecting your hair against UV? The answer is…YES, AND, it depends.

Reapplying hair SPF in the real world

One of the reasons it depends is due to a little factor called application and reapplication

You know when you buy body SPF and the label advises you to reapply every 80 minutes? Well first of all, it should actually be every 40 minutes according to Cantor, a sunscreen testing lab based out of New York. Cantor reports that SPF is best reapplied every 40 min.

Of course there are other sunscreen testing labs that recommend different times like the classic “80 minutes” but the difference with Cantor’s rec is that they do most of their sunscreen testing on actual people.

I digress. The point is, proper application and reapplication is required to ensure hair is getting protected from UV. But let’s talk about the real world. After you style your hair, are you really really going to go back in and apply more product throughout the day?

I mean, let’s be honest, it’s kind of a huge nuisance to pump out a wet product and reapply on dry, styled hair…It’s one thing if I’m at the beach or pool with already wet hair but other than that...aintgunnadoit

    Hi, Lisa. Thank you for this article. I want to ask, since you applied SPF on your hair, do you have to wash your hair everyday? I have wavy hair and I wash my hair twice a week only. Thank you in advance.

      Hi Debbie! All three of these hair SPF recs sit very lightly in the hair. I only apply them right before I dry my hair, like the same as a styling product…I honestly don’t even notice they are there. There are other hair SPFs that you can apply throughout the day and I would assume those would build up so I totally get the question. Hope this helps! Lisa
