I used the hard conditioner bar recipe from DIY Bath and Body on Etsy. I love it! The recipes are $10 each, or 3 for $25. Every recipe I have tried so far is wonderful. I believe
@Misschief and
@violets2217 also have good success with these recipes.
ETA:
@Gaisy59 I also have curly, coarse, and colored hair. Mine is also low-porosity, which does make a difference as to what type of conditioner you want. For instance, too much protein doesn't work well for low-porosity hair.
Fortunately, the recipe listed above is easily customizable with different ingredients as needed.
