Change Shampoos on a Regular Basis

Q: I've always heard that you should change shampoos regularly because they can become less effective. Is this true?
 
A: Yes and no. That’s a common belief, but it’s actually a bit of a myth. Shampoos don’t lose their effectiveness over time and they don’t suddenly stop working or lose their potency. However, there are good reasons to change up your shampoo routine every now and then.
 
For starters, some shampoos - especially moisturizing or conditioning ones - can leave behind residue. Over time, that build-up can weigh your hair down, making it look flat, dull, or lifeless. Also, using the same type of shampoo over and over might throw off the balance your hair needs. For example, if you constantly use a deep-cleansing shampoo, it might strip your hair of natural oils. On the other hand, relying too heavily on a rich, moisturizing formula might leave your hair feeling heavy or greasy.
 
Another reason to switch things up is that your hair’s needs can change with the seasons. In the winter, your scalp and hair may need extra hydration, while in the summer, you might benefit from something lighter and more clarifying. On top of that, your scalp’s oil production and hair texture can shift over time due to things like aging, hormones, medications, or changes in your environment.
 
Instead of constantly jumping from one product to another, it’s better to take a thoughtful, balanced approach. One smart strategy is to use two shampoos that complement each other. For instance, one that targets your main concern, like moisture or volume, and another that helps keep everything in balance, like a gentle clarifying shampoo. You don’t have to rotate them every wash, but using the clarifying one every few washes - say, every three or four - can help remove any buildup without overdoing it.
 
Most importantly, pay attention to how your hair responds. If it starts feeling dry, lean into more moisture. If it’s looking heavy or greasy, maybe it’s time to clarify. And whatever you’re using, make sure you’re choosing quality products that suit your specific hair type and concerns.

And don’t forget: your conditioner plays just as big a role in your hair’s health. It should work in harmony with your shampoo to keep everything balanced and looking its best.
