    Thank you for such an informational site and tips. Could we use cold process to make this shampoo bar?

    I am recently doing a bigger batch about 2 kilos in a big mould. A formula for olive oil soap that I made perfectly fine before, I just use the same formula increase proportionately, but the mixture went through gel phase and remains sticky. I wonder what went wrong. Could a bigger mould affect my results?

    • Jan says:

      Hi By! Yes, you sure can make this shampoo bar recipe cold process. At trace, add your essential oils, as desired, and then pour into molds. Just skip the cook part and let the bars cure for four to six weeks. Re the other recipe that you resized larger: did you rerun it through a lye calculator? It’s possible too that a larger batch might need some longer time in the mold if it’s thicker/deeper. You could also try decreasing the water next time, to help it firm up faster.

    is it possible to substitute the lye for castile soap?

    • Hi Blake! While castile soap is made using a form of lye, it can’t be substituted for lye directly. (You can kind of think of it in the same way that you can’t use a potato chip to replace the salt in a cake recipe.) In order to make soap (even castile soap or commercial soaps, unless they’re detergent based) you have to have oils + a strong caustic substance. In the olden days, they made their own caustic substance out of wood ashes. The problem was that it wasn’t consistent and nobody really knew how much to use to ensure a gentle soap. Now, we have a standardized product (sodium hydroxide for bars and potassium hydroxide for liquid soaps) that makes sure every batch turns out exactly balanced and gentle.
      During the soap making process, molecules of oil match up with molecules of lye. At the end of the chemical reaction, you don’t have oils or lye anymore – you have a brand new substance – soap and glycerin! It’s pretty amazing! Another way to think of it is how sodium and chloride (two things you wouldn’t want to ingest separately!) come together to form a new substance – salt. So, that was my long-winded way of saying that you can’t make soap without lye or another strong caustic substance. :) The lye is essential to the recipe.

    Hello! I just found your site today and would LOVE to learn how to make shampoo bars. However, when I click to go to the article at “Hobby Farms” the only thing that loads on that page is the ads. Can you give me a direct link to the directions and ingredients for shampoo bars?
    Thanks!

    Hi, I would like to try this recipe, but the link isn’t working. :(

  8. Shelley says:

    I get photos, but print areas are just blue question marks in boxes. Very disappointed.

    • Hi Shelley! Do you see this on my site or the Hobby Farms site? When I look at both, they look okay to me, so I’m not sure what’s going on with it.
      I found out that Hobby Farms is in the process of a major site update, so right now there will be glitches. It should all smooth out soon though.
      If it’s on my site that you see errors – I’d love to know more about it, so I can try to fix it!
      Thanks!

    Hey again! Just wanted to let you know that I checked back in today and when I redirected to Hobby Farms, the entire page (including ingredients and directions) loaded in a timely (as timely as rural internet can be!) manner! So excited to make these once I get all the ingredients together. Thank you so much!

    Quite frankly, the ingredients sound more like hair pulling (like oil pulling for teeth)…:))…ok I guess Lye and Oils make soap and glycerin.
    I was thinking this would be more ‘organic’ a recipe.
    Here’s the traditional herbal way of doing it:
    Equal portions of :
    Soapnut powder
    Acacia Concinna powder
    Phylanthus emblica (indian gooseberry)

    If you do not get your hands on the latter two, just use the first.

    Boil in water and rinse hair.

    You can add Hibiscus petals, lemon juice, yogurt or even do the last rinse with beer (left over).

    Pure herbal shampoo where yogurt is the conditioner.
