7 Curly Hair Myths That Are Probably Hurting Your Routine
I have been talking about curly hair for a long time with so many different people. I love working our booth at events because it allows me to have unique conversations with all different curl situations. Throughout all these curl chats, some similar threads present themselves and I have discovered quite a few pieces of advice that persist that I really wish would stop.
Most of these ideas started with a kernel of truth, or worked for someone with a very specific hair type in very specific conditions, and then spread across the internet until they became universal rules nobody questions.
The problem is that rules without context or nuance can easily be misapplied. And when your routine is built on rules that are not fully understood, your curls will suffer.
Here are seven curly hair myths I hear constantly, what the science actually says about each one, and what to do instead.
Myth 1: Curly hair should not be shampooed.
This one probably did more good than harm when it first spread, because a lot of people were washing their hair every single day with harsh cleansers and wondering why it felt like straw. Reducing that frequency helped a lot of people.
But somewhere along the way, "shampoo less often" became "never shampoo" or “wash with conditioner only” and that is where it becomes damaging.
Your scalp is living skin. It produces oil, sheds skin, collects environmental residue, and if you swim or sweat regularly, it accumulates all of that too. If you layer conditioner, leave-in products, and styling products on top of a scalp that has not been properly cleansed, the scalp can become clogged and will affect how your hair grows. The buildup also sits between your strands and prevents all of these products from performing the way they should.
The American Academy of Dermatology is clear that curly hair does need to be washed, recommending a minimum of every two to three weeks for optimal scalp health. In my experience working with hundreds of people across all curl types, most people with wavy and curly hair will want to wash more frequently than that. At least once a week is a more realistic minimum for most curl types. Tightly coiled hair is a genuine exception here. The degree of curl means scalp sebum travels more slowly and less evenly down the strand, so tightly coiled hair can often go longer between washes without buildup becoming an issue. But for the majority of wavy and curly hair types, especially those using gels, leave-ins, and styling products regularly, once a week is a better baseline than once every two to three weeks. And realistically, many of us could totally wash 2-3 times per week.
A good shampoo does not strip your curls. A shampoo that is wrong for your hair type might. The solution is finding the right cleanser for your hair type, not avoiding cleansing altogether.
Myth 2: Frizz means your hair needs more moisture.
Frizz is probably the most misdiagnosed curl problem there is. Because it looks like dryness, the instinct is to add more conditioner, more cream, more oil. Sometimes it is a moisture issue, but not always.
Frizz is not causedby just one thing. It is a visual symptom that can come from several completely different causes, and treating them all the same way is why so many people spend years adding product without ever fixing the actual problem.
Frizz can mean your cuticle is open and reacting to humidity. It can mean your curl clumps broke apart while your hair was drying. It can mean there was not enough hold to protect the curl shape as it set. It can mean product buildup is preventing your strands from aligning properly. It can mean friction from a towel or a pillowcase disrupted the curl pattern before it had a chance to dry. It can mean damage from heat or bleach is making individual hairs separate from the curl group. Or, it can mean your hair is too dry and is reaching out for moisture from the air around you.
Before you reach for one more deep conditioning mask, ask yourself when the frizz shows up and where. Frizz that appears while your hair is still drying is usually a hold or clumping problem. Frizz that shows up after a few days is usually a mechanical friction or a seal problem. Frizz that is concentrated at the ends is often damage. Frizz that appears everywhere despite a consistent routine is often buildup.
Getting that diagnosis right changes everything about how you approach it.
Myth 3: Oils moisturize your hair.
This one is very well-meaning but very scientifically incorrect. It causes a specific kind of frustration that I hear described constantly. Someone's curls feel dry. They add argan oil or coconut oil or another oil-based serum. Their curls feel better for a moment, maybe even look shiny. Then a few days later, they feel dry again, but now they also feel coated and heavy. So they add more oil. The cycle continues.
Here is what is happening. Moisture in hair means water. Oils are hydrophobic, which means they repel water. By their chemical nature, oils cannot add water to your hair shaft because they do not contain any water to give.
What oils can do is slow down water loss, reduce friction, and improve shine. Those are useful functions. But they only work when there is already moisture in the hair for them to seal in. Applied to an already dehydrated strand, an oil layer can actually make things worse by creating a barrier that prevents water from getting in later.
This is where I want to be clear about Silver Stone Apothecary products specifically, because we do not offer oil-based products. The difference between a raw oil applied directly to your hair and an oil that has been properly emulsified into a water-based formula is significant. When oils are emulsified, the oil molecules are broken down into much smaller particles that can actually penetrate the hair shaft and deliver their benefits from the inside. They also rinse cleanly without leaving a heavy residue behind. A raw oil sits on the surface because the molecules are too large to absorb. That coating can feel nice temporarily, but over time it contributes to the buildup that blocks hydration from getting in.
If your curls feel dry, the question to ask is not "what oil should I add?" It is "does my hair have enough water first, and is anything blocking it from absorbing?"
Myth 4: More moisture is always better.
This follows naturally from the oil myth because once people understand that oils are not actually moisturizing, they sometimes swing in the other direction and just add more and more conditioning products instead.
That can cause a different version of the same problem.
For fine curls and waves especially, too much conditioning weight is a real issue. When curls are over-conditioned, they go soft. Soft in a way that sounds good until you realize it also means flat, undefined, and unwilling to hold any shape. The strands feel smooth individually but they will not clump together, they will not hold a cast, and they will stretch out and lose definition as the day goes on.
A co-washing review from 2018 found that cleansing conditioners, while gentler than shampoo, can cause buildup because of residue left under the cuticle. The AAD specifically notes that people using gels, creams, and styling products may need a clarifying shampoo to remove the accumulation. That is not a warning against conditioning. It is a reminder that balance is an important part of ensuring your products continue serving their purpose.
Soft curls and healthy curls are not the same thing. Healthy curls have enough moisture to be flexible and supple, enough protein for internal structure and shape, and a clean enough surface to let everything work together. If your curls feel soft but look undefined, the answer is usually better cleansing, more structure, or a stronger hold.
Myth 5: Natural products are automatically better.
I want to be careful here because this one touches on something personal. Most of the ingredients in Silver Stone Apothecary products are plant-derived. I genuinely love botanical ingredients and I chose many of them deliberately. So this is not an argument against natural ingredients.
It is an argument against the idea that "natural" tells you anything meaningful about an ingredient. An individual’s ability to pronounce something is not a proper measure of whether a product is safe, effective, or right for your hair.
The appeal of natural products is psychologically real and well documented. People perceive natural things as safer and better without necessarily evaluating the evidence. The marketing industry figured this out a long time ago, which is why "natural," "clean," and "chemical-free" appear on labels even when they describe nothing specific and guarantee nothing measurable. Everything is a chemical. Water is a chemical.
What actually determines whether an ingredient is good for your hair is what it does, at what concentration, in what formulation, and whether it has been tested to perform consistently and safely. Poison ivy is natural. Lead is natural. Plenty of synthetic ingredients are gentle, effective, and well-studied.
I choose ingredients based on what they do for the hair and the scalp. Some of them happen to be plant-derived. Some are lab-synthesized. The question I ask is always whether they perform the job they are supposed to perform and are considered safe to people and the environment in the quantities used, not whether they qualify as "natural" by someone's definition.
Myth 6: Homemade products work just as well as formulated products.
Flaxseed gel is probably the most common DIY product in the fine curl and wave community, so let me use it as the example.
Fresh flaxseed gel can create a light film on the hair because the plant mucilage in flaxseeds does have some cosmetic activity. Some people love it and get decent results from it in low-humidity conditions. That is fine. But comparing it to a professionally formulated styling gel is not really a fair comparison, because they are not the same category of product.
A formulated gel is built around film-forming polymers designed specifically to create hold, resist humidity, distribute evenly through wet hair, and rinse cleanly after use. The formulation also accounts for pH stability, microbial preservation, and consistent performance batch to batch. Fresh flaxseed gel has none of that. It has no humidity resistance to speak of, which matters a great deal in the Pacific Northwest. It has a very short shelf life before it starts growing bacteria (also natural, but gross and dangerous in your hair care products). And the results can vary significantly depending on how you made it, how much flaxseed you used, how long you cooked it, and how you stored it.
The same principle applies to avocado masks, egg treatments, mayonnaise, and banana hair masks. Some of them may give a temporary sensation of slip or smoothness, but the visible hair shaft is non-living keratinised tissue that cannot be "nourished" the way a living cell can. What actually improves damaged hair are formulated products containing hydrolysed proteins sized to penetrate or deposit on the hair shaft in controlled amounts. There is research to support this. There is not comparable research supporting the egg mask.
This is not a judgment against enjoying a DIY routine. It is just an honest assessment that making something in your kitchen and making something in a lab are different endeavors with different outcomes.
Myth 7: Never use heat, including diffusing.
This is the myth I have the most personal feelings about because I diffuse my hair regularly and I genuinely believe it makes my results better, not worse.
High heat unquestionably damages hair. Repeated flat iron use, very high blow dryer temperatures, and excessive direct heat over time can denature proteins in the cortex and weaken the disulfide bond structure in a way that does not reverse. That is real and worth taking seriously.
But "high heat is damaging" does not mean "any heat is dangerous" and it definitely does not mean "air drying is always safer."
A frequently cited study from Yonsei University found that using a blow dryer at a distance of about 15 centimeters with continuous movement caused less internal cell membrane damage than natural air drying. The reason is that wet hair is structurally vulnerable. When hair stays wet for extended periods, the shaft swells and the cell membrane complex, which is essentially the material that holds the hair cells together, can be damaged by prolonged water exposure. That damage accumulates. For fine curls that can take hours to fully air dry, that is not a trivial concern.
For curly hair specifically, air drying for hours also means hours of friction against clothing, gravity pulling at the curl while it is trying to set, and the wind or movement disrupting clumps before the hold has a chance to lock them in. Gentle diffusing on low heat, low airflow, hovering rather than scrunching until the cast starts to form, can actually give curls a better shot at setting cleanly than leaving them to air dry through an entire afternoon.
I diffuse all of my wash days. I start with low heat and low airflow, hover the diffuser rather than pressing it into the curl, and only increase the speed once the cast starts to set. My curls come out with better definition, less frizz, and a stronger hold than when I air dry. That has been my consistent experience for years.
The goal is not to avoid heat entirely. The goal is to avoid excessive heat, protect against unnecessary damage, and use controlled drying as a tool for better results rather than a shortcut that destroys your hair.
There is a thread connecting all seven of these myths. They all came from somewhere real. Someone with very dry, tightly coiled hair stopped shampooing and saw improvement. Someone added oil to a wash-and-go and liked the shine. Someone tried a flaxseed gel and thought it felt okay.
The problem is not that the advice was wrong for every person who gave it. It is that hair science gets flattened into absolute rules, applied to curl types and routines it was never designed for, and repeated until nobody remembers why it started.
Your curls are not going to respond to rules. They are going to respond to the right approach for your specific hair, your scalp, your climate, and your lifestyle.
Understanding what each step in your routine is actually doing is more useful than any checklist of approved and banned ingredients.
