Since taking CBD, the hair which had not grown on my arms for 7 years started growing again. It's too early to say what the full benefits will be (I am actually taking it for chronic fatigue syndrome), but this is a remarkable initial response. I will mention that the label dosage was too high for me (5ml per day), and caused me to feel lousy to begin with. If this happens to you, reduce the dosage down to half or less, as I did.
