Taking a dip and cooling off in a refreshing pool is one of the many joys that we look forward to each summer. But a day of swimming laps or floating around in chlorine-filled water can often wreak havoc on your hair.
While one of the tell-tale signs of chlorine damage is a green hue on blonde hair, you may even notice dryness or a waxy feel, making it hard to run a brush through your locks. That's why we asked a hair expert to help break down the damaging effects of chlorine on hair and how to help manage and prevent it.
How does chlorine affect your hair?
"It will affect your hair color — from yellow to green — and a lot of people can associate green with it but yellow can be a factor too, it can look almost orange. And you’re going to start to feel a build-up on it, so it’s going to feel dry. It can feel a little waxy," says Tiffanie Richards, Master Colorist at Louise O'Connor Salon in New York City. She even refers to it as "Barbie hair" since it will feel like plastic doll hair that is hard to comb.
While everyone can be affected by chlorine damage, there are certain hair types that are more susceptible to changes in color and dryness. While Richards says blondes will most often experience obvious changes in color, brunettes and redheads can be affected, too. In fact, any hair texture that is more porous, such as curly hair that's already naturally dry, will feel the effects.
"If you color your hair, have highlights or anything like that, that’s also a really big game-changer ... basically the thing with chlorine, it is a gas form, so it has the potential to get into your cuticle and open and deposit the green tone," says Richards. Once the chlorine absorbs into your hair, she says anything that you use product-wise will be difficult and take and longer to process, including shampoos and color-processing.
How can you protect your hair against chlorine?
If you're not up to wearing a shower or swim cap in the pool (we understand!), Richards suggests pouring bottled or filtered tap water on your hair, which she says will help fill the hair cuticle with clean water, so not as much chlorine will be absorbed.
Another trick worth trying? Richards recommends, "Leave-in conditioning treatments, which are also going to fill in your cuticle, so anything you can put into your hair that is healthy for your hair or clean for your hair before you jump into the pool, that’s gonna be beneficial."
If you're wondering if there's anything that you shouldn't be using in your hair prior to getting in the water, Richards says you'll want to avoid any styling products where one of the first ingredients contains alcohol. "Alcohol is going to open your cuticle and make it more porous and susceptive to taking in anything else," she explains. "You typically want to use stuff that is moisturizing ... so that's going to keep that cuticle nice and hydrated and closed."
How can you fix chlorine-damaged hair?
If you have blonde hair, the first thing you don't want to do is reach for the purple shampoo. Richards says this is the biggest mistake that blondes can make and it will turn their hair even more brassy and metallic-like. In fact, blondes will want to stay steer clear of toners altogether, she says, and the best way to counteract chlorine damage is to get an in-salon or at-home treatment.
If you are looking to treat your locks at home and the damage hasn't gotten too bad, Richards suggests washing your hair with a clarifying shampoo. And the good news is, you don't have to spend a lot of money on them, she says the drugstore brands such as Pantene, will do the trick. "Clarifying shampoos are pretty standard. They’re not meant to hydrate at all they’re meant to remove," says Richards.
As for conditioners, she mentions you'll want to invest in a good leave-in option or even opt for a hair mask since it's heavy enough to keep your hair cuticle closed and hydrated.
Once the chlorine is out, the last step you'll want to take to maintain your hair treatments is to install a shower filter. "It's really important to keep fresh water on your hair, especially since once you remove the chlorine, your hair can be more susceptive to copper in our shower water," Richard explains. "So you're typically going to want to reach for a shower head that has a filter in it and that's gonna protect against further chlorine deposit and anything else that can potentially get into your hair."
Best products to prevent and treat chlorine-damaged hair
Richards says Malibu C is one of the best brands that you can use to treat and prevent chlorine damage. She says this shampoo from the Swimmers Wellness line is great to use right after swimming to prevent it from settling in. According to the brand, this formula will help remove chlorine and copper, as well as help retain your hair's moisture and prevent it from feeling brittle.
"If you’re wanting something at home, Malibu C also makes an at-home crystal remedy and that removes any kind of mineral deposit as well," says Richards. According to the brand, by leaving this in your hair for five minutes (before shampooing), it will help remove and prevent that green tint and any chemicals your hair may have absorbed from the water.
The brand also sells the entire kit, which includes the shampoo, conditioner, and four packs of the crystal remedy.
Richards says she likes carrying around and using the Rahua leave-in conditioner, and says it's especially great for pool days because it contains a UV protectant. Containing hydrating ingredients to lock in moisture, the brand says it will repair weak and damaged strands and will help your hair feel overall smoother.
If you're looking for a hair mask, Richards says this color care mask from L'Oreal can help keep your cuticle closed without weighing down your hair — she even says you can use a mask instead of a normal conditioner to help treat the damage.
