Weigh out and mix together the water, aloe juice, and glycerin in a heat-resistant container.
In another heat-resistant container, weigh out the oils and BTMS. (You can also use a double boiler insert.)
Heat the oils and water mixture in a pot of water. Heat until the BTMS melts, stirring until the BTMS is fully incorporated into the oils. Once the BTMS has melted and the temperature of all of the ingredients is around 70º-75ºC/160º-170ºF, remove them from the heat.
Mix together the hot, water-soluble ingredients and the hot oil mixture. Ideally, both should be around 70º-75ºC/160º-170ºF. Stir constantly until all of the ingredients come together well and are emulsified.
During the cooling process, continue to whisk together the ingredients periodically. The mixture will continue to get thicker as is cools.
Once you've allowed the mixture to cool down to around 30ºC/85ºF, you can add in the more heat-sensitive ingredients like the preservative, the wheat protein, the d-panthenol, and the essential oil(s).
Check the pH of the conditioner and adjust it if needed. (You can use a few drops of lactic acid to lower the pH if necessary.)
Bottle your DIY hair conditioner.
Don't place the cap on the container until the mixture reaches room temperature. This prevents water from condensing on top of the conditioner. Once cool, you can seal the container and use or store the conditioner.
Ideally, use the conditioner within 3 months.
