    What is the use level on the cationic guar? It should be a sufficient thickener ~0.8-1.2% on its own depending on how much water is in your formula. At lower levels it will only condition.

    have you tried rosemary oil instead of shampoo to try and thicken your hair? rice water apparently works aswell

      Rosemary oil?
      Shampoos are meant to clean hair. Putting oil on your hair is exactly the opposite of cleaning hair.

        I believe DrWrinkle understood that the shampoo should thicken the hair 😀

        Not that Sara is seeking advise how to thicken the shampoo.

    You could also try Hydroxypropyl Methylcellulose.

    I have successfully thickened a shampoo that had Sodium Cocoyl Isethionate, Cocamidopropyl Betaine, and Decyl Glucoside as the surfactants using Hydroxypropyl Methylcellulose in the past. I think it would be a great choice for you, and it may also function as a foam booster/stabilizer.

    Hai Sara21, I hope I can share a bit frm my experience.

    When formulating a shampoo, usually we need :

    Primary Surfactant

    Secondary Surfactant / Co_Surfactant



    Any active Ingredients (depends on the extra benefit we want)



    From your ingredients,

    Sodium Cocoyl Isethionate acts as a primary surfactant because of its anionic.

    Lauryl Glucoside which is a non-ionic surfactant as the co surfactant.

    Guar as the Moisturizer while it also can provides some thickening properties.

    But, since most of “guar” has a cationic charge, you need to add some “amphoteric surfactant”* like Cocamidopropyl betaine or Lauryl hydroxysultaine or anything else.

    And… you need to know the type of ^guar^ that you use. Generally there was 2 type of Guar. One of it can swell after you add some citric acid or any acid to bring it to its optimum pH.

    If the viscosity still not achieve your goals & you okay with some PEG thickener, you can try to use is as well.

    And do not forget your total surfactant need to be at least around 11 - 13% solid content when you make a shampoo for a good cleansing properties.
