If you swim laps at the pool every morning, you already know how good it feels. It is arguably one of the cleanest ways to build a lean physique and clear your head before the day starts. But let's be honest about the aftermath. A few weeks into a dedicated swim schedule, you look in the mirror and realise your skin feels tight and parched, your hair feels like straw, and the products that usually work suddenly seem to make little difference.
Every public pool relies on chlorine to keep the water safe for swimmers. But while it kills bacteria, it doesn't stop there. As Dr. Mikki Singh, board-certified dermatologist and medical director of Bodycraft Clinics, puts it, "Chlorine is an oxidising disinfectant, and it doesn't distinguish between bacteria and your skin's natural oils. It strips away the sebum and lipids that hold the barrier together, raises the skin's pH, and leaves it more permeable and less able to retain water."
That's why your skin starts feeling dry long before it actually looks damaged. And if you're swimming outdoors, there's another factor at play. "The chlorine problem rarely comes alone; it's almost always chlorine plus sun, and the combination is what does the real damage," says Dr. Singh. Adding to it all, higher melanin levels make many Indian skin tones more prone to pigmentation when chlorine and UV exposure trigger inflammation.
The same chlorine that’s weakening your skin barrier can also take a serious toll on your hair. Annette Syiemiong, creative lead at Looks Salon, explains, "Chlorine attacks the proteins that give hair its strength, roughening the outer layer so strands look dull and tangle easily. It also strips the scalp of its natural oils, often leading to dryness and flaking." Over time, repeated exposure can leave hair brittle, accelerate colour fade, and allow minerals like copper to build up on the strands.
Most swimmers don’t notice the damage until it is too late. This is because they try to fix the problem after they get out of the pool instead of protecting their skin and hair before they get in. Dr. Singh says, “People tend to under-protect before and over-correct after. The ideal is the reverse."
That preparation starts with your hair. Wet it thoroughly with fresh water before you get into the pool. "Saturated, coated hair simply can't soak up as much chlorinated water," adds Dr. Singh. Syiemiong also recommends applying a leave-in conditioner or a little coconut oil through the mid-lengths and ends before putting on a silicone swim cap to reduce exposure further.
The same principle applies to your skin. Apply a moisturiser before your swim to create a protective layer, then layer on a water-resistant broad-spectrum sunscreen if you're swimming outdoors. Dr. Singh also recommends steering clear of strong acids, high-strength retinoids, and aggressive scrubs on swim days, since chlorine already leaves the skin under stress.
Once you're out of the pool, don't wait until you get home. "Rinse skin and hair with fresh water the moment you get out," says Syiemiong. Follow that with a lukewarm shower and a gentle, soap-free, pH-balanced cleanser, says Dr. Singh. As tempting as a hot shower might be, it'll only strip the skin barrier further.
Now that the chlorine's gone, give your skin a little love and care. Apply your moisturiser while your skin is still slightly damp to seal in hydration. Dr. Singh recommends ingredients such as ceramides, hyaluronic acid, niacinamide, and glycerine to help restore the skin barrier after every swim.
Your hair needs the same attention. Use a clarifying or chelating shampoo once or twice a week to remove chlorine and mineral build-up, and always follow with a conditioner, leaving it on for three to five minutes before rinsing. And if you're swimming several times a week or have colour-treated hair, adding a weekly deep-conditioning mask or bond-building treatment can help restore strength. Treat this routine as a non-negotiable part of your workout. Just as you wouldn’t skip your warm-up or recovery, don’t overlook your skin and hair.
