I finally made it back to the pool today after almost a year away. It felt wonderful to be in the water again. And of course, I washed my hair with my 365-day cured Castile shampoo bar as usual afterwards.
As I was drying my hair, I thought of those of you looking to move toward natural care and a simpler life, away from toxic or overly complicated chemicals. I actually first wrote about this topic a couple of years ago when I started making shampoo bars, but returning to the pool reminded me just how important these "honest truths" are.
Because a traditional Castile Shampoo Bar is not the same as bottled shampoo. It is not the same as salon shampoo. It is not even the same as many modern “natural shampoo bars” on the market.
It belongs to an older, slower way of cleansing. And because of that, it needs to be understood properly.
To begin with, let’s be honest about hair shedding. Whether you use the most expensive salon shampoo or a traditional Extra Virgin Olive Oil Castile bar cured for 365 days, your hair will still shed. Hair shedding is part of the natural cycle of the body. A natural shampoo bar does not stop normal hair fall, and it should never be sold as if it does.
But I also understand why people feel worried when they first move from commercial shampoo to traditional soap. Their hair may feel sticky, heavy, dry, tangled, grippy, or as if more hair is coming out than usual. That does not always mean the soap is wrong for you. Often, it simply means your hair and scalp are adjusting to a completely different way of cleansing.
A true Castile bar is made through saponification, using real oil, lye, water, and time. My version is made with Extra Virgin Olive Oil and cured slowly for 365 days. It is not designed to behave exactly like a commercial shampoo. If you expect it to feel the same as a bottled shampoo from the first wash, you may be disappointed. Not because it is inferior, but because it works in a different way.
The pH Truth: Real Soap Is Naturally Alkaline
One of the most misunderstood things about traditional soap is pH.
You may see advertisements claiming that handmade soap is “pH neutral” or balanced to 5.5, similar to the skin’s natural pH. I prefer to be clear: that’s impossible. A true soap is naturally alkaline. That is part of what makes it soap. If a natural soap dropped below a pH of 8, it would literally fall apart and turn back into a puddle of oil.
A proper Castile soap usually sits on the alkaline side, often around pH 8–9. This is not something to hide or be afraid of. It is simply the nature of real soap.
If a soap is pushed too low in pH, it no longer behaves like a true soap in the same way. So when we talk about a 365-day cured Castile bar, we are not saying the pH has become neutral. That is not the point of long curing.
The point is mildness, maturity, hardness, and the quality of the lather.
When you wash your hair with an alkaline soap, the hair cuticle can lift slightly. This is one reason your hair may feel grippy, rough, dry, or tangled during or after washing, especially if you are used to bottled shampoo with built-in conditioning agents, silicones, or smoothing ingredients.
The benefit is that traditional soap can cleanse very thoroughly. It can help remove sweat, oil, dirt, chlorine after swimming, and product residue from the hair and scalp. The downside is that if the hair is left in that alkaline state, it may not feel smooth. The cuticle needs to be encouraged to settle back down.
This is where the finishing step matters.
After washing with a Castile Shampoo Bar, I recommend using a simple acidic rinse or acidic aftercare step. This may be diluted apple cider vinegar, lemon water, or aloe vera gel. You do not need anything complicated. The purpose is to help rebalance the hair after the alkaline wash, smooth the cuticle, and reduce that dry, tangled feeling.
- The Good: It allows for a deep, honest clean, stripping away dirt and pool chemicals like chlorine.
- The Catch: If you leave those cuticles open, your hair stays rough and tangles easily, which leads to breakage.
-
The Fix: A simple acidic rinse (like lemon, apple cider vinegar, or my Aloe Vera method) settles the pH instantly. It "closes the door" on the cuticle, making your hair shiny and smooth without needing a drop of silicone.
This is why I always say a Castile Shampoo Bar is not just a product. It is a small ritual: wash, rinse well, rebalance, then let the hair dry gently. Very tragic, I know, that nature sometimes asks us for one extra minute.
Why Cure a Castile Shampoo Bar for 365 Days?
So why cure the bar for 365 days if the pH does not become neutral?
Because pH is not the whole story.
A freshly made soap and a long-cured soap can feel very different on the skin and hair. During curing, water slowly evaporates from the bar. The soap becomes harder, denser, and longer lasting. The lather becomes creamier and more stable. The bar becomes milder in use.
With olive oil soap especially, time changes the character of the soap. A young olive oil soap can feel soft, slimy, or less refined. A long-cured Castile bar becomes firmer, smoother, and gentler. It does not become “neutral,” but it becomes more mature.
This is why I wait 365 days.
Not because I want to make things difficult, though apparently I have chosen the slowest possible business model in a world obsessed with instant everything. I wait because olive oil soap rewards patience. A 365-day cured Castile bar has had time to settle, harden, and develop the mild, creamy character that makes traditional olive oil soap so special. It becomes less aggressive in use, more elegant in lather, and much more beautiful as a daily cleansing bar.
It is not rushed. It is not forced. It is allowed to become what it should be.
The Transition Phase: Why Hair Can Feel Different at First
When people first switch from commercial shampoo to traditional soap, they may go through a transition phase. This is very common.
Commercial shampoos and conditioners often contain smoothing agents, conditioning ingredients, or silicones that coat the hair and make it feel slippery and soft. When you move to a simple soap-based routine, those coatings may gradually wash away.
Suddenly, your hair may feel different. It may feel heavier, drier, waxier, or less silky than expected. This does not always mean your hair has become worse. Sometimes it simply means you are feeling your hair without the same synthetic coating.
Hard water can also make the transition more difficult. Minerals in hard water can react with real soap and create residue, often called soap scum. On the hair, this can feel waxy, sticky, dull, or heavy.
This is one of the biggest reasons some people struggle with soap-based shampoo bars. It is not always the bar itself. Sometimes it is the water, the rinse, or the way the hair is dried afterwards.
If you live in a hard-water area, rinsing very well and using an acidic rinse becomes even more important. Without that step, the hair may feel coated instead of clean.
A note on the "powder" bars
You have likely seen many “handmade” or “natural” shampoo bars at markets that look like pressed powder, clay, or a compacted paste. They are often promoted as natural, plastic-free, gentle, or botanical, and many people assume they are the same thing as traditional soap-based shampoo bars.
But they are not always the same.
Many of these bars are actually syndet bars, which means synthetic detergent bars. They are usually made by combining powdered or noodle-form surfactants with binders, clays, butters, oils, fragrance, and other additives, then pressing or moulding the mixture into a solid shape. In simple words, they are often industrial-style cleansing agents made into bar form.
While those bars might be handmade in the sense that someone pressed the ingredients into a mould by hand, the ingredients themselves tell a different story.
This does not automatically make them bad. Some syndet bars are well-formulated and may work beautifully for many hair types, especially because they can be made with a lower pH and can behave more like bottled shampoo. For many people, that familiar feel is exactly what they want.
But they are not the same as a traditional Castile Shampoo Bar made through saponification.
My Castile Shampoo Bar is not pressed from powder. It is not a detergent bar shaped to look handmade. It is made from Extra Virgin Olive Oil, water, and lye through the old process of soapmaking, then cured slowly for 365 days. The cleansing comes from the transformed olive oil itself, not from powdered synthetic surfactants.
| Feature | Your Castile Bar | Powdered (Syndet) Bar |
| Ingredients | Natural oils (Olive) + Lye | Concentrated surfactants (like SCI or SCS) |
| pH Level | Naturally alkaline (pH 8–10) | pH-balanced to the scalp (pH 4.5–5.5) |
| Hair Feel | Can feel "grippy" or rough without a rinse | Feels like liquid shampoo; usually very smooth |
| Hard Water | Can react with minerals to create "scum" | Rinses clean regardless of water type |
That is why it behaves differently. That is why it needs to be understood differently. And that is also why I do not market it as if it were a quick, salon-style shampoo replacement. It belongs to a slower, older tradition of cleansing. A syndet bar may feel more familiar if you are coming from bottled shampoo. A Castile Shampoo Bar may ask for a little more patience, a proper rinse, and an acidic finishing step. But in return, it gives you something very simple, very traditional, and very honest.
So when you see the words “natural shampoo bar,” it is worth asking one simple question: Is it a true soap made by saponification, or is it a detergent-based bar pressed into a solid shape?
Both can exist. Both can have their place. But they are not the same thing.
Why you should wait to brush
Another thing to remember is that hair is most fragile when it is wet. This matters even more after swimming. Chlorine, water, washing, and friction can all make the hair feel more vulnerable.
After I wash my hair, I do not brush it straight away. I gently blot it with a towel and leave it alone until it is at least 70% dry before combing. Brushing wet, tangled hair can cause breakage, especially if the cuticle is still lifted after an alkaline wash. Sometimes what people call “hair falling out” is actually breakage from rough handling.
The soap is not always the villain. Sometimes the brush is simply doing too much, as brushes often do when unsupervised.
My post-swim recovery ritual
Because I prefer to keep my routine simple, I use a very gentle method to soften the hair and rebalance it after washing.
After swimming, I wash my hair with the 365-day cured Castile Shampoo Bar and rinse very thoroughly. Then I use aloe vera gel as my balancing step. Aloe vera has a naturally slightly acidic nature, which makes it useful after an alkaline soap wash. It helps the hair feel softer and smoother without needing a heavy conditioner.
The Aloe Vera is naturally slightly acidic, which helps to "close" the hair cuticle that the soap opened. My Rose Beauty Bath & Body Oil is a blend of Jojoba, Argan, and Avocado oils, along with Rose-infused Olive oil and Rose Geranium. Jojoba and Argan are incredibly light and soak into the hair shaft, while the Avocado and Olive oils provide a protective seal.
How to apply it: While my hair is still damp, I take a small amount of Aloe Vera gel and mix in just one or two drops of the Rose Beauty Bath & Body Oil in my palms. I rub them together and scrunch them into the ends of my hair. The Rose Geranium oils smell beautiful and completely mask any scent of chlorine.
This routine is not fancy. It is not a miracle treatment. It is simply thoughtful care. Cleanse well. Rinse well. Rebalance. Protect the ends. Let the hair dry gently. That is the whole idea. When you understand the rhythm, a Castile Shampoo Bar becomes much easier to use. Without the rhythm, it can feel confusing.
Who Is a 365-Day Cured Castile Shampoo Bar For?
A 365-day cured Castile Shampoo Bar may suit people who want a simpler and more traditional way to cleanse their hair and scalp.
It may suit those who want to reduce synthetic surfactants such as SLS or SLES, avoid plastic bottles, use fewer ingredients, or return to a more old-fashioned soap-based routine. It may also suit people who prefer very simple formulations and do not want strong fragrance, heavy conditioning agents, or complicated product layers.
But it may not suit everyone, and I think it is important to say that honestly.
If you want instant salon-smooth hair with no adjustment period, no acidic rinse, and no learning curve, this may not be your ideal shampoo bar.
If your hair is heavily bleached, chemically treated, very porous, or already extremely dry, you may need extra care, a gentler routine, or a different product altogether.
If you live in a very hard-water area and do not want to use a rinse, you may find traditional soap difficult for hair washing.
That does not mean the bar is bad. It means the method may not match your hair, water, or lifestyle. Not every product has to suit every person, despite what marketing departments bravely pretend while holding a ring light.
The Honest Way to Use It
This is why I prefer to explain the truth instead of pretending that Castile soap is perfect for everyone. My bar has a naturally alkaline pH. It needs to be rinsed properly. It works best with an acidic finishing step. It may require a transition period. It may not suit every hair type or every water type. But when it is understood and used correctly, it can become a beautiful, simple, and honest part of a natural hair care ritual.
For me, the beauty of a Castile Shampoo Bar is not that it performs like a commercial shampoo. The beauty is that it does not try to.
It is simple, slow-made, long-cured, and made from real oil through a traditional process. It asks you to slow down for a moment, to understand your hair, to rinse properly, to notice what your body actually needs.
This is not always convenient, but it is meaningful.
My 365-day cured Castile Shampoo Bar will not stop natural hair shedding. It will not magically repair damaged hair overnight. It will not behave exactly like a salon shampoo.
But it will give you a traditional, minimal, olive-oil-based way to cleanse. It will give you a bar that has been made slowly, cured patiently, and created with honesty.
For those who want to simplify their routine and return to something more natural, this little bar can be a very good place to begin.
Use it with patience. Use it with understanding. Rinse well. Rebalance. Be gentle with your wet hair. And please, do not judge a traditional Castile Shampoo Bar after using it like a commercial shampoo and then attacking your wet hair with a brush.
Even soap deserves a fair trial.
