If the blockage is in the "U bend" [the U shaped bit of pipe just below the sink strainer at the bottom of the basin] then put a shallow bowl or water-catcher beneath the U bend and unscrew the U bend and remove the obstruction. This method works if the obstruction is non-organic.
If you suspect that the obstruction is organic (hair, fat, grease, cabbage etc.) then a chemical approach may be necessary. There are commercial products that contain dangerous caustics [lye and very strong detergents]. These often work but have risks.
Another approach is a "snake".. a flexible but stiff piece of cable or wire that you push gently but repeatedly back and forth while the sink is partly full of warm or even hot water (hot shifts grease).
Of course there is always the "plumbers friend", also called a 'plunger' which is composed of a cup shaped rubber sucker and a handle.
To use it properly partly fill the sink with warm water and exclude all possible air from the cup [this greatly increases the hydrostatic force {look it up}. Then slide the plunger (no air inside) from the side of the plug-hole. Now push down on the plunger and slide it over to directly above the drain hole.
Push and pull vigorously (keeping air out of the cavity inside the cup).
If these techniques don't work.... call a plumber!
