DIY Conditioning Shampoo Bars

In my continued quest for the best easy DIY shampoo bar, I wanted to try my hand at adding some additional conditioning agents to the Stephenson Syndopour base. This base is the best and easiest way I have found to make shampoo bars at home but even though I loved the last batch of bars I made, I wanted to try and amp them up just a little more:)


What makes DIY shampoo bars so great that I keep tinkering with this recipe? They are super easy to travel with, no need to worry about spills or TSA compliance, you can customize them to fit your own taste and as you can get so many bars out of one container of base, you are cutting down on plastic usage as well as just your overall environmental foot print so they are a really sustainable product option.


For this recipe I added in both colloidal oats for it's scalp soothing abilities as well as argan oil for it's conditioning properties and ability to help with overall hair health and I LOVE how they turned out. I scented this batch with eucalyptus and peppermint so the bars not only have a clean fresh scent but they also help with cleansing your hair.


To make this recipe you will need:

1 TSP Colloidal Oats (premade or grind your own)

Soap Colorant(optional)



To make:

  1. Melt your Syndopour Base and Soap Colorant down in the microwave in 30 second intervals until completely melted. You could also do this in a double boiler if you prefer to.

  2. Next add in your colloidal oats, argan oil and essential oils and stir well to combine. I ended up using a mini whisk to help incorporate the colloidal oats but what I would suggest instead(and what I plan to do next time) is to hydrate the oats in a tsp of isopropyl alcohol and add that to your shampoo base. This will help with clumping as well as you won't make air bubbles in your base with the whisk. The isopropyl alcohol will evaporate out of the finished product.

  3. Once everything is well combined, pour your base into your silicone mold and allow to set up for 2-4 hours.

  4. Next remove them from the mold and store in a cool dry location until you are ready to use them. I typically store mine in a wax paper bag but you could also shrink wrap them.

These bars work great. The base in general lathers really well and the addition of the colloidal oats and argan oil definitely helped with the overall conditioning I could get out of the bar. I have found that I don't have to use a seperate conditioner, just the shampoo bar though I still do a deep conditioning treatment once a week. If you make these shampoo bars, let me know how you like them in the comments of this post:)
