Sometimes this: Is a normal variant, sometimes it could be blood that is dried, melanoma at times needs to be ruled out.

Various things: In people with skin of color it may be a normal variation. Skin growths may also cause them, both of the benign and malignant kind. See your dermatologist.

Different causes: Black stripes down 1 nail may be subungual hematoma. Red or brown streaks may be splinter hemorrhages. Brown/black lines from nail plate to tip are often seen in people with dark skin & are normal. Subungual Melanoma can cause nail ridges & dark colors of cuticle. It most often effects the thumbs or big toes. Dark lines may be due to other illnesses. Get checked out when in doubt.

Black lines: This could be caused by your skin color with melanin within the nail root. If there is one line or so and your light skinned i would have it looked at.

Nail lines: Changes in nails can result from trauma, fungus, and systemic conditions such as psoriasis. I would recommend evaluation by a podiatrist or dermatologist if you are concerned.
