Syndet Shampoo Bar Recipe For Dry Hair – No Lye

Try making this syndet shampoo bar at home, with rosemary, nourishing oils for hair and scalp, and a mild surfactant, SCI. Yes, you can make shampoo at home, easily!! This post focus on good ingredients for dry hair, and how to use them in a shampoo bar.

My Experience with Homemade Shampoos

I’ve tried using soap for some weeks, and my hair felt heavy, a bit sticky and my scalp was slightly itchy. So I gave up. I didn’t like to use the vinegar rinse as well. I’ve also experimented this more natural liquid shampoo made with a blend of surfactants. Maybe because it’s a clarifying shampoo and not something you use every day, I didn’t like it either, again, my hair felt heavy and sticky and a bit greasy. It’s great as a complement to a daily shampoo, though.

I was actually a bit sad that I had to stick with supermarket shampoos, as they were better than the natural alternatives I’ve experimented with. 

Until I’ve come up with this recipe from Silvana Liviero, a brasilian cosmetologist, in her facebook group Saboaria Artesanal para Iniciantes of a shampoo bar with two versions, one for oily hair and one for dry hair. I’ve tried the dry hair version with some changes of my own.

Great success!! My hair feels normal, clean, loose, even after weeks of usage. It turns dry in the ends if I don’t use a conditioner for several days, but apart from that, it’s a great, more natural alternative, without the high pH and its inconveniences. And I control the ingredients!

Syndet Shampoo Bar Recipe For Dry Hair

The base ingredient is only one surfactant, Sodium Cocoyl Isethionate (SCI), a surfactant ingredient used in mild synthetic cleansing bars. It is synthetically made using coconut oil as a base (the strongest oil regarding cleansing).

Sodium referrs to its salt structure, Cocoyl makes reference to its base of coconut oil, and Isethionate is the acid required in combination with the other two components to produce a mild lather. Without more addictives, it works well in hard water, something I can confirm – I have hard water at home and this bar lathers very well.

The rest are hair-loving ingredients, such as rosemary-infused water, coconut oil, jojoba oil or shea butter.

Hair Loving Rosemary

Rosemary is great for hair treatment, especially rosemary essential oil. Rosemary has been used by many to promote hair growth successfully. Using rosemary essential oil could very well do the same for you.

Science and personal experience together both strongly suggest the essential oil does protect against hair loss, particularly that related to male or female pattern baldness. It may even be effective for alopecia.

Rosemary essential oil is a simple remedy that you can use at home, and it may even be competitive with commercial products. What’s more, it’s quite safe when used correctly and yields very few side effects.

In this recipe, we use a rosemary water infusion and rosemary essential oil. You may also infuse the argan or jojoba oil with rosemary for more rosemary extract for your hair.

Natural Ingredients for Dry Hair

This formula, not surprisingly, integrates a couple of oils to moisturize your scalp and hair:

Coconut oil: among other benefits, including antisseptic and calming properties that may help fight dandruff, coconut oil “special power” is its ability to penetrate very well into the hair shaft combined with being a natural saturated fat. It helps seal in hair moisture, and may help reduce protein loss in hair. This prevents dry, brittle, breaking hair and split ends. Because of this, it might also give a sense of longer hair, which may be why some believe to promote hair growth (not proven scientifically).

 Shea butter or cocoa butter: basically, these ingredients are very conditioning and moisturizing. They are also packed with vitamins, minerals and anti-oxidants, therefore being very nourishing. Even if shampoos are not leave-on products, your need of a conditioner might reduce with this shampoo and this is the reason why.  

– Argan oil: is a very conditioning oil with a fat profile very similar to human sebum, making it an almost-perfect moisturizer for skin and hair scalp. As your scalp already has a tendency to over-produce sebum, this oil will help it to reach a good balance, with minimum sebum production. Not to count with a rich content in vitamins, especially vitamin E (an antioxidant), and several minerals that will nourish your scalp and hair. Jojoba oil is a great replacement for argan oil, if you already have it.

Rosemary essential oil, as stated before, helps with hair growth. It’s also a good hair conditioner, and helps reducing acne, inhibiting acne bacteria. It helps with oily hair in the sense that will keep your scalp clear of bacteria and your hair hydrated, reducing the need to produce sebum.

Peppermint essential oil is best known for the menthol content, and its unique mint scent. It has antibacterial properties, and is also very refreshing, due to menthol content. This will help keep your scalp calm and clear of bacteria. It is also known to stimulate hair growth, but it’s not scientifically proven.

Recipe Variants

Making natural cosmetics has the advantage of creating tailored-made products to your unique needs. You are in full control of the ingredients and you know yourself better than anyone. You just need to use both to your advantage. 

To adjust a recipe to be perfect may take time and patience, but in the end you will have a high-end product relatively cheap. As this is NOT a lye recipe, by keeping the oil weight relatively the same, you can change the oils and see what works best for you – check Natural Oils For Skin to know in detail the great cosmetic properties of the 12 most common oils.

You can also change the essential oils. I’ve used rosemary and peppermint as both are very good for hair treatment, but mostly because I love this blend. But you can use others, like lavender, rose geranium, or even a “citrusy” essential oil, like lemongrass.

Liquid Phase

Cooling Phase


Preparations and Good Practices

  • Disinfect all your equipment before starting. You can boil some of your equipment (like the double boiler, glass cups, spoons), and use a solution of 1 liter of water with 1/2 cup of bleach, for items that are not heat-resistant (like the milk frother, plastic cups or the lotion containers)
  • Check out the post What Is a Syndet Bar or the tutorial videos above. They don't have a recipe but explain in general the steps and ingredients to produce a syndet bar.
  • Measure all ingredients and prepare your workstation. Wear a mask as the SCI releases an irritant dust cloud

Liquid Phase

  • Put a pan with water into the stove (any water as this is for bagne-marie)
  • Add the oils and water into the double boiler or a metal jug. Let it heat in low heat, up to 50ºC or until a little bit before the solid oils melt completely

Solid Phase

  • Add the solid phase ingredients and mix well with a spoon. I prefer to use a fork as it works as half spoon, half whisker. Preferably, add the solid ingredients 1/3 at a time, and mix gently but thoroughly before pouring more solid ingredients. Let them incorporate well in the mixture.
  • Mix and heat the mixture in low heat until it has the consistency of homogeneous mush or porridge.
  • Remove the double boiler or jug from heat. Mix a bit to cool down the mixture.

Make Your Bars

  • At around 50ºC or lower, add the cooling phase ingredients: essential oils and the preservative. Mix well.
  • Take 1/4 tsp of the mixture and dilute it in 1 tsp of warm water. Dissolve it well and use a pH strap to measure pH. Should be 5-6.
  • If pH is too high add a bit of lemon juice or citric acid, or baking soda if it's too low. Mix very well and measure the pH again.
  • Pour the mixture into a soap mold. After unmolding let it dry for 2 or 3 days.
  • Your shampoo bar is ready to use!

    • Hello Bonnie,

      I have to be honest, I didn’t try it and I have no idea if it works. But in theory it should be no problem. Goat’s milk is good for hair providing hydration and proteins.
      It won’t be the same as cold process with goat’s milk because the milk will chemically change in cold process, while in this syndet bar there’s no true chemical reaction.

      If you feel like trying, make only one bar with goat’s milk and see how it goes. And let me know 🙂

      Best Regards,

  1. I always liked naturopathic and alternative medicines compared to the danger stricken Big Pharma products. Seeing that you can create a natural shampoo and soap for your body will do more than give you better hair and skin; it will probably save yo life! There are thangs in these products that are creating problems long term in people. thanks for the informative post; you definitely got a productive site going on here! 

    • Hello Nicholas, thanks for your comment.

      I wouldn’t go as far as “saving your lfe”, but I do believe that the cosmetics industry is going a bit too far using artificial chemicals. Why not investigate better/cheaper ways to use more natural ingredients?  

      Still, I have nothing against them, they have to follow regulations, which are actually strick in Europe, and they do need to prove that their products are safe – natural products can be dangerous as well, if you don’t follow proper procedures!

      Having said that, I do love DIY natural beauty products, where I can fully control all ingredients. I like to know that the lotion or shampoo with jojoba oil actually HAS a good percentage of jojoba oil, something I don’t trust with over-the-counter products. Ok, they do have jojoba oil if it’s advertized, as they are forced to make true claims – the problem is the quantity, no one says that the amount in it is effective.

      I don’t want to extend further myself, I would just like to say that I am not against commercial products. I simply like to know and let everyone know that there are alternatives: it’s like food, you can buy microwave food, you can go to a restaurant and you can make your own food with fresh, natural ingredients. With my website, you also have the option to do your own beauty and hygiene products at home 🙂



  2. This is a great recipe! I love using natural alternatives when it comes to anything really. Often I research and study herbalism as I prefer this way compared to chemically based medicine. I also use natural body wash and soap and have made a few DIY ones. This shampoo is something I have never done before and love that I now have a really good recipe to try. Thank you!

    • Hello Alyssa, thanks for your comment and interest in this post 🙂

      I have been using a similar recipe that I plan to post soon, for my oily hair and I can tell you that, after 3 days, my hair looks just a bit oily on the roots. Unlike before, I couldn’t stand 2 days without washing my hair, as it looked like I was licked by a cow…. 

      It’s not something that happen overnight, I have been using these syndet shampoo bars for months now. And SCI is a bit expensive 🙂 but it’s very worth it, especially compared with $20 pharmacy shampoos, as this is actually effective long term. 

      The wonderful thing about making your own shampoo bar is that you can costumize it: 

      – you can use herbs you grow at home and infuse the other ingredients (water, oils) for enhanced properties, 

      – you can use your favorite essential oil whether is tea tree, peppermint, rosemary or even lavender, 

      – you can use some aloe vera gel if you also have a dandruff issue or itchy scalp,

      –  you are only using one detergent and a very mild one for your shampoo (SCI, coco betaine, or coco glucoside are the kind of detergents you find in baby shampoos), not three or four of the harsher ones like many over-the-counter shampoos. 

      – you are not using soap, and this way you are avoiding hair chemical cut due to high pH (natural soap is also a great product to wash your hair, and people that uses short hair or has a strong shaft will probably have no issues with it. But it’s not advised long term due to pH of 7-9 which damages the hair shaft over time) 

      Am I against over-the-counter shampoos? Not really. Probably some people will feel good and clean only with shampoos with a strong clansing action. But in general they are too agressive to your hair and scalp. I am starting to believe that many people have oily hair/roots because the shampoo is too drying and your scalp overproduces sebum. It’s a vicious cycle you can break with this mild shampoo bar recipe 🙂
