Why Homemade Castile Bar Soap?

I stopped using consumer-packaged shampoo products around 2015 when I kick-started my healthier better lifestyle. Instead, I tried natural ways including using baking soda rinse, but found out it dries out hair too much. After a while, I settled on castile bar soap. I would buy Castile bar soap made from organic cold-pressed oils. Needless to say, they are expensive, around $7 for a bar which lasts maybe 3 weeks since I wash my long hair every day. In addition, I do not get to choose what kinds of oil to include in the bar soap.

Then one day my husband encouraged me to make DIY bar soap and said it didn’t seem that difficult when he watched several videos.

The truth is I have been making my lotion, toothpaste, exfoliating scrub, serum, hair oil, facial, lip balm, and all kinds of DIY personal care products for a while, but making soap rarely crossed my mind.

How to make Castile Bar Soap at home?

But it turns out that making castile bar soap is easier than I thought. At a high level, all you need to do is dissolve the lye in water and combine it with the boil. Then blend them and pour the mixture into soap molds.

However, because the process of dissolving lye in the water creates a huge amount of heat, you do need to be careful about the steps.

  • Step One – Dissolve lye (Sodium Hydroxide) in water. This process generates loads of heat, therefore always add a small amount of Sodium Hydroxide (about 1 tsp) at a time to the distilled water, and stir to blend before adding the next batch.
  • Step Two – Heat the oil in a glass measuring cup. I found this Pyrex 4-cup glass measuring cup extremely handy.
  • Step Three – Slowly pour the lye solution into the oil.
  • Step Four – Use an immersion hand blender to blend the combination until it shows consistency. But remember not to over-blend. It needs to be pourable.
  • Step Five – Pour the mixture into soap molds and let it solidify. Once it is solidified, in about 2 days, remove the soap from the molds and let it cure.

What oils to use when making Castile bar soap for Shampoo?

I use sweet almond oil as the base carrier oil, as well as coconut oil and castor oil. Castor oil is especially good for hair as it contains special fatty acid concentrations that prevent hair loss and boost hair growth.

For body soap, I still use sweet almond oil as the base carrier oil and add coconut oil and jojoba oil. Jojoba oil is extremely powerful for hydrating and nourishing the skin.
