The sun will bleach your hair, but you probably shouldn’t let it
REMEMBER that amazing spray that worked magic on your hair. Unfortunately “sun-kissed” hair isn’t exactly a good thing.
BACK in the ’80s and ’90s, many Aussie girls forked out their hard-earned cash on a bottle of SunIn, soaked their hair, then lay out in the sun, hoping for lighter tresses.
But it turns out we probably didn’t need the extra help that spray provided. Spending all summer outdoors will lighten your hair even if you don’t put anything extra in it.
Trichologist Anthony Pearce says it’s all down to ultraviolet radiation. The colour pigment in our hair shafts is oxidised by exposure to ultraviolet radiation, that according to Pearce, is “the same chemical process as having the hair bleached”.
This might sound like welcome news for those who spend hundreds of dollars (and hundreds of hours in the hairdresser’s chair) attempting to lighten their hair. But be warned, “sun-kissed” hair isn’t exactly a good thing.
“The sun can ‘bleach’ hair blonde but in doing so degrades the hair as well,” Pearce, founder of Anthony Pearce Trichology, explains.
A lighter hair colour as a result of time spent in the sun equals a permanently weakened hair shaft. Hello split ends, dryness and a whole lot of irreversible damage.
The solution? For starters, wear a hat when you’re outdoors and opt for hair products that provide protection from ultraviolet radiation — they’re like sunscreen for your hair.
“I’m a big believer in protecting your hair against UV rays the same as we do for our skin. It is especially important for weak or colour-treated hair,” explains Lisa Farrall, hair expert for Fudge Professional.
“It is also important to think of your scalp, especially your part. I find the best trick is to use a high SPF lip balm on your scalp to avoid it burning, it’s easy to apply with no grease and it will stop you from having a flaky scalp.”
If you are looking to speed up the hair lightening process, there are some great options out there that don’t involve sun damage. For anyone who grew up in the late nineties or early noughties and abused hair lightening product Sun In like I did (I still shudder thinking about the Coke-coloured patches on my head), you’ll be pleased to know the technologies and formulas have improved dramatically.
The key? Three-time Australian Hairdresser of the Year and Co-Creative Director of ELEVEN Australia, Joey Scandizzo, recommends simply asking for subtle highlights.
“Most hairdressers understand what ‘sun-kissed’ hair is — a great way to describe it is to say you would like subtle variation through the front or the ends which are generally the places the sun hits,” explains Scandizzo. “Sun-kissed means you want to go only one or two shades lighter, nothing too drastic.”
If you’re religious about keeping your hair out of the sun but still find your hair has lightened by the time March rolls around, there are a couple of reasons for that.
“Salt water will also lighten hair in it’s dual effects with ultraviolet light. Salt water can add to hair damage as it can swell and dry hair shafts; making them more porous and prone to breakage,” explains Pearce.
Oh, and that chlorinated pool you’ve been swimming in? It’s not your hair’s friend either.
“As an alkaline, chlorine is potentially the most damaging to hair. Hair should be double shampooed immediately after swimming. Depending upon what chemicals are added to the pool water, Chlorine pools can gradually cause a green/blue discolouration to hair,” says Pearce.
