I've had a few bad haircuts in my lifetime, and it sucks having to wait for my hair to grow. I started taking a teaspoon of blackstrap molasses daily because I heard it was good for preventing anemia (my iron is often low). The first thing I noticed was my finger nails got hard and long within a couple weeks.
Next, I noticed my hair getting super long rather quickly. I went from shoulder length hair to hair down to my lower back in only 6 months. My hair had never grown that quickly previously. To this day I still take the molasses 3x a week but I am going back to taking it daily because I recently got another bad haircut. lol
