Fortunately, this one’s been cracked as an old wive’s tale. There are several factors that affect the way our locks react to washing after a while- but none of them involve your hair care regimen.
“A shampoo does not stop working because your hair gets used to it,” says Dove stylist Cynthia Alvarez. She explains, “If your shampoo stops giving you the results you want, the condition and needs of your hair have most likely changed, or the season may have changed—it’s more humid, the sun is stronger, or the air is drier. Your state of health or hormone levels may also be different from a recent illness or your monthly cycle.”
Alvarez also revealed that changes to our hair may also be a result of water pressure, your shower head, or the amount of minerals and chlorine in the water.
Andre Gunn of Honey Artists explains, “It really is just a combination of factors… generally, the conditions under which we are shampooing,” he says. “Are you at home with your filtered shower head? Or are you on the road where there are high amounts of minerals and chlorine in the water? Is the weather cold and damp out? Hot and dry outside? These factors all affect our skin and hair alike. A balanced (hair) diet of filtered shower water and breaks between washing will give optimal results.”
The level of mineral deposits coming out of your shower head plays a significant role in damaged hair. If you live in an area with high levels of mineral deposit, it’s likely causing all of it to be chilling in your mane, making your locks super thirsty and extra prone to damage. Water with high levels of mineral deposits- often referred to as “hard water”- also keeps hair from being able to absorb moisture.
Since it’s not likely that you’re ready to start packing boxes and move to a soft water area, there are two ways you can combat hard water. First and foremost, invest in a water filter. It’s not exactly inexpensive, but your hair will thank you in the long run.
In the meantime, don’t stress. This is one beauty myth we can chalk mostly up to marketing.
