Yes.Great results! I used this recipe' yesterday but forgot to include the mustard. It works even without the mustard. Next time I'll add the mustard yet knowing it works beautifully without it, I can compare the difference. I am amazed and delighted at the results! . It covers regrowth and gives a lovely light flaxen-colour blonde results on my lighter hair with my dark streaks seeming darker. I'm happy with it. Thanks for posting.
