I can only think back to going in a pool one single time the last decade or so, which was on Tenerife last year. I do however have the memory of how much the chlorine in the pool wrecked my skin when I had swim classes as a child. Which I did in this classy swim hall from 1926 right here:
I grew up near some pretty good beaches and my parents own a boat, so I'm a total, unapologetic snob when it comes to where I swim. I only went to said pool because that was where the classes were, and I will forever scoff at Mr Igors bizarre idea that it's fine to swim in a lake. This is something I have only degraded myself to in landlocked Switzerland on really hot days.
No, swimming takes place at a proper saltwater beach with warm and fine sand between your toes. Preferably in the archipelago south of the island where I grew up, so you can just anchor the boat up by one of the little uninhibited islets and have the entire beach to yourself: No screaming children, no broken glass in the sand, no dog shit. Just the entire little islet to yourself.
This is the only proper way to spend a day at the beach. Fight me. I will die on this hill.
Anyways. Hair and chlorine.
If you can’t
get to a decent beach and you have to swim in a pool, chlorine in the water is actually a good
thing. Chlorine is a disinfectant that kills bacteria in water, such as E. Coli. and Cryptosporidium which can make you very, very sick with diarrhea, Pseudomonas which causes rashes and swimmer's ear, and Legionella, which causes Legionnaire’s disease and Pontiac fever. Basically, chlorine kills all the nasty you get when a bunch of people of unknown hygiene splashes around in pleasantly warm water.
Just as chlorine is good for killing bad bacteria, it indiscriminately kills the good as well. That means killing the benign bacteria that keeps malign bacteria from colonizing the acid mantle. The skin has something like a thousand different bacteria strains living peacefully on it, and even with names like Staphylococcus epidermidis and Streptococcus pyogenes, those are the good guys. You want to nurture and protect them so they don't die and leave living room for the bad guys.
Chlorine also does a good job of breaking down dirt and oil, which means it will destroy the sebum and the polyunsaturated fatty acids that the good bacteria need for maintaining the right pH for them to thrive. Stripping oils from scalp, skin and hair causes dryness to the skin and hair, which increases the risk of damage. It can also provoke dandruff. Removing the oils from your hair will cause a loss of flexibility in the strands and increase hairs natural porosity. Increased porosity in chlorine water is a bad circle, where the hair can absorb more chlorinated water which again cause more porosity. If your hair is already dry or damaged from perms or dyes, it can increase the damage from chlorine even more.
Bleached or highlighted hair is also more at risk for turning green. The infamous greenish tint is actually caused by oxidized copper in the poolwater which binds to the proteins in hair. Just like that pretty, turquoise tone on copper we see on some buildings and statues.
If you wear contact lenses like me, chlorinated water absorbs into your contact lenses which can irritate the surface of your corneas. I'm going to bring extra lenses so I can discard mine after swimming. Maybe I will even invest in a pair of swim goggles if the water park becomes a place we will visit more frequently.

How to
prevent chlorine damage?
Since the
problem with chlorine comes from absorbing it into hair, the first step is to
make sure your hair is completely soaked through with unchlorinated water
before getting in the pool. Rinse, rinse and rinse. Give your hair time to
absorb it. You can also take breaks during swimming to take a quick rinse in
tapwater.
To further
block the absorption of the chlorinated water, a swim cap is the way to go. It
will keep your hair nice and compressed and decrease the flow of chlorinated
water into the tapwater soaked hair. Silicone swim caps are the way to go
because they are flexible, hair friendly and bacteria can’t grow on clean
silicone.
A quick
google search found a ton of specialised, chlorine-combating products. Often
expensive. And often without a listed ingredient list. I’m deeply skeptic of
any product like that, especially if they don’t list the ingredients. I'll save my money.
Even though
leave in products will eventually be broken down by the chlorine and washed
away by the flow of water, they can slow down the process of chlorine absorbing.
Amodimethicone is not water soluble and is known for causing build up, but in
this case it’s a good thing and might prevent silicone absorption. Quaterniums bind
to microscopic damaged areas of the hair to protect them and some of them are
known for building up: Polyquaternium 10 and 11 especially. Again, this is
normally something to avoid in large doses, but before swimming in a pool it
could be a good idea to load up on amodimethicone and quaterniums.
And of course
there are oils. Oils will naturally repel water and keep water from
absorbing into the hair.
“Repairing”
chlorine damage
Yes, I
know. You can’t repair damaged hair. But still…
First step
out of the pool is to rinse. Rinse, rinse and rinse. Get as much of the
chlorine out before anything else.
Just as the
chlorine damage-preventing the products mentioned before, I found lots and lots
of specialised, chlorine-damage repairing products. Again: Often expensive. And
often without a listed ingredient list. I would not spend money on those.
If
anything, I would go for a weak apple cider vinegar rinse to remove build up
from chlorine and poolwater residue. Or go for a shampoo I know and trust.
Basically not Head and shoulders and not something that promises too much, doesn't want to show the ingredient list and is too expensive.
A deep
conditioner would be a good idea afterwards too. Get something with protein in
it to replace the broken protein molecules in your hair. Look for cetearyl
alcohol, glycerin, hyaluronic acid, panthenol, propylene
glycol, sodium PCA, sodium lactate and sorbitol for moisturizing
ingredients. Niacinamide aka vitamin B3 is a very effective skin-restoring
ingredient against ageing and environmental stress.
