I think I answered no to this poll originally but stand corrected (for myself at least). This past week I've noticed quite a bit of fine baby hairs above the temple on my hair line. Never had them before so I was surprised. For the past month I've been using JBCO exclusively to seal my edges and nape; it's alternated with other oils for my ends.
So I'm guessing the JBCO has the nutrients my scalp needed for them to grow. Nothing else has changed in my routine or diet.
