Why You Shouldn't Mix Your Shampoo And Conditioner Brands

One additional benefit of using shampoo and conditioner from the same product line is that if you have a specific hair need — such as dryness or baby-fine strands — you've got two carefully calibrated weapons attacking the problem at once. "The ingredients are designed to support and complement one another — kind of like a twin-set — so no way can you mess up!" noted the AARP blog.

But what if you have more than one concern? (As if frizz were your only hair woe!) If that's the case, you can successfully combine shampoo designed to saves an oily scalp, with a conditioner meant to soothe untamed ends (via Blueshin). You just have to read the labels carefully, looking for a shampoo that addresses your scalp's condition and a conditioner that's based on your desired hair style. If this brand-switching sounds like hair-washing heresy, fear not. Some experts believe product manufacturers may have ulterior motives when they insist it's bad for us to use different brands. "[Brands] sell matching products because, well, they want to sell more product," cosmetic chemist Sally Raffy told Refinery 29. "By recommending that they work well together, they're able to sell an entire line. A lot of it is marketing."
