Sun-damaged hair? Here’s how to repair and protect the scalp this summer

TOI Lifestyle Desk

Does sun exposure damage hair?

We rarely think about our hair getting a "sunburn" because it doesn't sting or peel the way our skin does. But the reality is just as damaging, if not more so. Prolonged exposure to intense sunlight severely compromises your hair's structural integrity, stripping away moisture and degrading vital proteins.(Image Credits: Pinterest)

How does this happen?

The UVA rays act like a relentless bleach. They target and alter the melanin—the natural or artificial pigment—in your hair. This is why colour-treated hair fades or turns a brassy orange so quickly in the summer. (Image Credits: Pinterest)

But it doesn’t end there

Then comes the second wave: UVB rays. These are the literal structure-breakers. UVB radiation systematically breaks down keratin, the crucial protein responsible for giving your hair its strength, elasticity, and shine. Tips that can help.(Image Credits: Pinterest)

The physical blockade

The absolute most reliable defence against UV damage is surprisingly simple. You have to physically block the rays from hitting your hair in the first place. It might sound incredibly basic, but throwing on a wide-brimmed hat or wrapping a chic silk scarf around your head provides unparalleled protection.(Image Credits: Pinterest)

SPF for your strands

Hair sunscreens and specialised UV-protectant mists are not just clever marketing gimmicks; they are summer necessities. These sprays physically coat the hair shaft, working to deflect and absorb those harsh rays before they penetrate.(Image Credits: Pinterest)

The golden rule of swimming

Summer naturally means more time in the water, which unfortunately compounds the sun damage. Chlorine and heavy saltwater violently strip away your hair's natural, protective oils. This leaves your hair highly vulnerable the second you step back onto your lounge chair. The absolute best trick? Drench your hair with clean, fresh water right before you jump into the pool or ocean. If the "sponge" is already full of fresh water, it physically cannot absorb the damaging pool chemicals or drying salt.(Image Credits: Pinterest)

Deep hydration and damage control

Implement a heavy-duty hydrating mask or deep conditioning treatment into your weekly routine to restore lost lipids. And please, do not forget your scalp in this process. The scalp, especially along your part line, is highly susceptible to severe sunburn. A quick dusting of SPF powder over your part can literally save your hair follicles from peeling and permanent damage.(Image Credits: Pinterest)

Give your hot styling tools a long vacation

Compounding environmental heat damage with mechanical heat from blow dryers is a recipe for snapping strands. Finally, commit to a minor trim every six to eight weeks. It is the only guaranteed way to stop those inevitable summer split ends from travelling further up the hair shaft.(Image Credits: Pinterest)
