Shampoos and conditioners are always recommended to be used as a pair from the same brand and range. “For best results, use with brand X’s matching shampoo/conditioner!” is what you’ll always see at the back of every shampoo and conditioner. Of course, most of it is marketing talk; each beauty product should be able to be used on its own without needing to be paired with another product from the same brand for best results.
But you see, the thing is, as much as a part of my cynical brain tells me I don’t need to use shampoos and conditioners from the same range and brand together, the other part of me says I have to. I don’t know why but I have a thing for matchy-matchy shampoos and conditioners.
It’s very rare that I buy a single shampoo or conditioner without getting the matching partner. For example, if I picked up a Pantene Aqua Light shampoo, I’d have to get the Aqua Light conditioner too. If you tell me that there’s no need to use them together, I know. I KNOW! Somehow I seem to think that I’m breaking up a pair and I couldn’t do it.
