Thanks @
CodeRed. I purchased it to use in this recipe that claims to give you growth boost, but again, I haven't used it yet. I might try incorporating it into my DC like you. Anyway, here's the recipe FYI:
Mustard Hair Mask
Apply for 1 month 1 time per week. Mix 2 tablespoons dry mustard powder (ground mustard) add 2 tablespoons of hot water, 1 egg yolk, 2 tablespoons olive (peach, burdock, and any other cosmetic oil) 2 teaspoons of sugar. Apply to scalp only. Cover with plastic cap and wool cap and leave on no less than 15 minutes or up to 1 hour before rinsing out. Be sure to coat your hair with oil (coconut, etc.) before applying as the mask can be drying to your hair
