What makes Soypa shampoo and conditioner bar different

For years I tried finding a shampoo, whether liquid or shampoo bar, that wouldn't irritate my scalp and make it itchy after washing my hair.  The majority of shampoos I tried were too harsh and stripping away natural oils, leaving my scalp constantly irritated. Also, specifically shampoo bars I tried were lacking nourishing ingredients, and I was never 100% happy with how my hair and scalp reacted. Conditioner bars had their own problem, too hard to glide through hair properly, so they really work too. Since I am really dedicated to use any plastic-free alternative, I felt demotivated. 

So I decided to formulate my own, with real care put into it. It took me over two years to get right. The difference between an okay formula and a great one was literally in a few grams. I tried so many versions until I got this one that you can also buy in the webshop.

What's in Soypa shampoo bar

People often ask me if they can use my soaps for hair, but I don't recommend it. Here is why. Cold process soaps are usually at a pH of around 9 to 10, and that higher pH can affect the hair cuticle, leaving it open and prone to damage. For skin, this pH level is fine, since skin has a living acid mantle that buffers itself and returns to its normal pH within a few hours of washing, even after something alkaline. Hair doesn't have that. It's a dead fiber with no way to repair or rebalance itself. Once an alkaline product forces the cuticle open, it stays open until it's either sealed back down with something acidic or simply grows out.

My shampoo bar isn't soap. The base is built around gentle surfactant -  sodium cocoyl isethionate (SCI) instead of the commonly used sodium lauryl sulfate  (SLS) which is more irritating. But also much cheaper. I formulated this shampoo at a pH of around 4.5, close to hair and skin's own natural acidity. At that pH, the cuticle stays closed and hair looks shiny and smooth. 

Every ingredient in the bar is there for a reason. Amla powder is rich in vitamin C and antioxidants and has a long history in Ayurvedic hair care, where it's used to nourish the scalp and add shine. Clay is there for a different reason, it gently absorbs excess oil, adds a bit of volume, and gives the bar some slip. Jojoba and argan oil bring lightweight hydration, and shea butter adds deeper nourishment without weighing hair down. Each ingredient is selected to complement the others, with a real function for hair or scalp.

What's in the conditioner bar

The conditioner bar uses BTMS50, a mild, plant-derived conditioning ingredient. It detangles hair and reduces frizz. Olive wax adds richness and helps lock in moisture, improving hair's elasticity so it's less prone to breakage. Hibiscus powder is rich in antioxidants and amino acids, and it's also a traditional Ayurvedic ingredient for hair care, valued for strengthening hair and supporting scalp health. Alongside it I added just a touch of rice protein, a lightweight, plant-based protein that adds strength and shine without weighing hair down or causing buildup.

Jojoba and argan oil are in there too, restoring moisture and protecting against dryness and split ends. Glycerine, a humectant, draws moisture in and helps keep hair from becoming brittle. There's also chamomile extract, added for its own calming, soothing properties on the scalp.

Both the shampoo and conditioner bars contain rosemary extract, rich in antioxidants which help with scalp health and shiny hair.

Homage to women

While formulating these, I looked into what women around the world have used for hair care for generations, and it helped me a lot to choose right ingredient. Olive oil used by women in the Mediterranean, shea butter and argan oil in Africa, jojoba used by Native American women in the desert regions of North America, and amla and other herbs in Ayurvedic traditions in India. I wanted to utilise the knowledge collected for centuries from wise women around the globe.

Switching doesn't mean compromising

If you've tried a shampoo bar before and gone back to bottles because your hair or scalp didn't agree with it, that's a fair reaction, many bars on the market are often too harsh or too basic. But that doesn't mean solid bars can't work well. It just means the formulation has to actually be built with hair and scalp health in mind, not just convenience or a plastic-free label. That's what I spent two years trying to get right.

One shampoo bar lasts me around two months, and the conditioner bar even longer. My hair feels stronger and shinier than it has in a long time, and I haven't had scalp irritation since switching to my own bars.
