So the moment you’ve been waiting for, does swimming turn blonde hair green:

will swimming turn blonde hair green truth

Yes, unfortunately this fact is completely true! Despite what you have heard, it isn’t the chlorine turning your blonde locks into a murky green, it’s actually the copper. This can also be a concern if you shower with copper pipes sending your water flow or you shower with hard water. Your hair won’t immediately turn green, but over time it will change and ruin your dye job. To prevent your blonde hair turning green in the shower, get a water filter on your shower head to soften the water and filter out unwanted mineral deposits.

If you’re not about that swimming cap life (we get it) then it’s important to protect your strands with a leave-in conditioner. Applying a leave-in conditioner like The Good Stuff Color Protect Milk, prior to getting in the pool will create a layer of protection between your strands and the copper.
