does IAS show more than actual speed or less?for headwind and tailwind

Nothing. As an aircraft changes direction in a right handed 360 degree turn, for example, with a wind out of the north, the IAS will stay constant. However, the ground speed will change to more than IAS when there is a tailwind and less when there is a headwind.

Airspeed means the speed of motion through the air. A headwind will make the ground speed slower than the airspeed, while a tailwind will make ground speed faster than the airspeed.

Steady wind won't affect the indication of airspeed in flight. The plane is just moving through a moving air mass.
A change of wind speed or direction can, if it is abrupt enough, affect the IAS.
Windspeed can affect the IAS when the plane is on the ground. That is one reason for making the takeoff and afterlanding rollout into the wind.

Indicated airspeed is the speed of an aircraft relative to the air mass in which it flies indicated by the ASI regardless of wind direction and speed and aircraft heading.
Although indicated airspeed may not be actual or true airspeed. True air speed is indicated airspeed corrected for altitude, air temperature and barometric pressure (density altitude)

wind dosnt effect airspeed. it affects ground speed.

It's AIRspeed.
Your groundspeed changes,
airspeed doesn't.
