the white half moons on fingernails. I never had any, however since using jojoba oil on my nails everyday, I have started to get them. Are they a sign of healthy nails? Just wondering. Thanks!

You are 'feeding' the nail plate with much needed oils and moisture, so it would stand to reason that the health of your nails is improving. When the nails are healthy, you will see the lunula on most of the nails; the most on the thumbnail and the least (if any) on the pinky.
