How I Use Castile Soap to Wash My Hair

If you’ve been following this blog for any length of time you’ve probably seen my post series called “Why I don’t Shampoo My Hair”. In it I explain  why I refuse to use sulfates in my hair. I also avoid dimethicone, parabens and paraffinum liquidilum (petreoleum jelly).  I do co-wash, but not all the time because I feel that it doesn’t get my scalp as clean as I would like. I also REFUSE to pay $27 for a bottle of shampoo.

So what’s a frugal curly girl to do?

Well, I decided to try washing my hair with castille soap a little while ago and I love it! I’m a fan of the peppermint myself, cuz it makes my scalp all tingly. It’s also crazy convenient, because I always have tons of the stuff around, because I clean half of my house with it! (For more ideas on how to use Castile soap all over your house, check out My Dr. Bronner’s 30 Day Challenge Post.)

So here’s my formula :

Liquid Castile Soap Shampoo

  • 3 parts water
  • 1 part castille soap

This usually works out pretty well. I just use an old conditioner bottle to keep it in and a 10oz bottle lasts me about 6 weeks of weekly washings. (Unless Sexy decides to use it as body wash, and then, well….yeah).

You can find the same kind of castille soap I use on my hair right here in the Savvy Shop.

    I use castille soap but I also use Earth Mama Angel Baby Shampoo which is basically castille soap, they use shea butter as an added conditioning ingredient instead of stuff like jojoba oil which actually builds up much faster and is not as easily washed out.

    I do use mineral oil exclusively on my hair, the fragrance free laxative form. My hair has never been healthier and free of tangles. Mineral oil is both safe and natural and great for those who have relentlessly dry hair.

    I have loose fine curls but my hair has been really long most of my life. It is quite dry without mineral oil and very fragile. Until I started using it I could not even braid my hair anymore. Now I wear it however I want so long as it is nothing apparently damage which I do not do anyway.

    Hi ! I started using Castile about 2 weeks ago and so far I hate it :( I use a 2 tbsp rose Castile and 1 tbsp coconut milk mixture and my hair is so greasy, flat and dull. I honestly don’t know what to do. Should I try it with water? I really feel like giving up.

    @Laurie I’m so sorry that it isn’t working for you. I think that all of that oil might be too much for your hair.First, I would rinse your hair with a 1/4cup of apple cider vinegar mixed with 2 cups of water to get all of the residue out. If you want to try using it again, I would try 1 tbsp with 10-12 ounces of water. Mix or shake it well and put it in an applicator bottle so that you can target your scalp. You hair will get washed as you rinse it out. Not every product works for everyone. If you don’t think this is method, I recommend trying this product or a shampoo bar like this one as a healthy alternative.
