Based on your description there could be multiple causes for black lines on the hands. Cigarette smoking , splinter haemorrhages on the nails , local trauma should be looked for and occupational history should be taken before any work up is advised.

It's possible that you may have something called acanthosis nigricans. Acanthosis nigricans (AN) is when the skin on some parts of the body is darker and thicker than other skin. AN has nothing to do with being dirty, and won't go away with bathing or scrubbing.

Lots of people who get AN don't have any other health issues. But it can be a sign that someone may be at risk for other medical conditions (like diabetes). Or it can show up because of medicine someone is taking. So it's a good idea to get checked out by a doctor.
