Yes, you can also make it into a paste. Here is an Ayurvedic remedy: Equal amount of grounded black sesame seed and Amla oil (Gooseberry oil), and apply it to scalp for 30 minutes, then wash off. Do this for several months, and then check your hair and see if your normal color starts to grow on the gray hairs. It was so exciting when I found those two hairs. I am pregnant now, so I can't take black sesame seed, so I had to stop. But will start again in a few months, good health to you!
