Friedman points out that conditioners can be potential allergens for some people, which can cause allergic contact dermatitis.
However, he notes that this would only be in a very low number of people. What's more, if you're acne-prone and fail to rinse out your conditioner thoroughly enough, it's possible that you could break out on your face, neck, or body since conditioner can clog pores just like any product comprised of oils. Another potential adverse effect of conditioners is that they can weigh the hair down. For instance, Romanowski says if you use more than a palm-sized dollop, or if you use a kind that contains a very high concentration of oils and emollients read the label to find out this can contribute to the hair looking greasy or flat.
He notes that this is most common in people who have fine hair. According to cosmetic chemist Kelly Dobos, hair can become more brittle, susceptible to tangles, and prone to breakage with the absence of a conditioner. Your hair may look duller and less shiny, he had, so there's that. Do yourself a favor and just condition your hair, folks.

How often should you use conditioner on your hair? For a quarter of a century, I willfully deceived myself into believing that hair care was simple.
Then I succumbed to vanity and, inspired by the rising number of women going platinum , dyed my pixie cut blond. The bleaching itself was an ordeal, but nothing compared to the nightmare that awaited: being forced to finally navigate the world of hair care and trying to figure out what was marketing spin and what was real. I quickly became a hair truther. I was skeptical of shampoo even as I shelled out for the "color-protecting" kind.
I asked my friend Allison — whose flowing golden locks represent what heights of hair glory can be achieved — for deep conditioning recommendations, though I had no idea how it worked. Finding solid answers to hair questions is hard. Our first instinct when trying to understand a medical breakthrough might be to read the research, but our first instinct when switching shampoos is to ask a friend with really nice hair what works for her.
And the beauty industry spends millions to market products with clever wording that imply big promises. Most beauty research is done by cosmetic chemists — the scientists that formulate and develop products — and a lot of it is published in academic journals like the Journal of Cosmetic Science.
These journals are usually paywalled and access to the articles which are dense and full of jargon is expensive. So, after watching my bank account dwindle from expensive treatments, I brought my questions to cosmetic chemists who actually understand the science behind the claims. Hair has three main components, says Randy Schueller, a cosmetic chemist who blogs at The Beauty Brains. The outside, or the part that everyone sees, is called the cuticle and made of five to 10 overlapping layers of protein like shingles on a roof.
The cortex holds long bundles of proteins that give hair its strength and keep it from breaking. And at the center is an empty zone called the medulla that helps insulate the hair.
Not all hair has the medulla. When it comes to hair products, the most important part is the cuticle. When the layers of protein lie smoothly against each other, hair looks shiny and smooth. Everyday things like brushing and washing hair makes the cuticle stand up straight.
That makes it frizzy and more prone to breaking and split ends. Even during my days of blissful ignorance, I could tell that something was changing because suddenly the other shampoos were making claims like "gentle" and "sulfate-free. The rise of conditioner is probably the biggest trend right now as natural-looking hair becomes more popular, says Margie Nanninga, a business analyst at market research firm Mintel.
And people are shelling out. We bought 5 percent more conditioner in , according to market-research firm Euromonitor International. And not just any conditioner, mind you, but a lot more "cleansing conditioners" that we use to "co-wash. Co-washing sounds fancy, but just means skipping shampoo. It began around as a niche trend among the kind of people who are quick to try new beauty tricks, says Nanninga.
Another shift is happening in the so-called "ethnic hair care" category. Fewer people are buying relaxants as black women, especially, are going for the natural look. How do shampoo and conditioner work anyway? Shampoos contain a type of molecule called surfactants. One end is attracted to water, and the other end is repelled by water and attracted to oil. The oil-loving end attaches to the grease and dirt in your hair, while the other end attaches itself to the water from the shower.
That way, when the water washes out the shampoo, it also washes out the grease attached to it. Conditioners work by smoothing the outer layer so that the cuticle layers lie flat.
