Thanulee,
The parameters to get the Object as the hair are:
The Thickness of the Hair Material will determine the size of the object, except for the length.
The length is given by the Hair length.
The subdivision of the Object should align with the Segments of the hair, or greater than the Hair.
The Hair Material needs to be Transparent.
In the example I stored the Dynamic and switched on Rigit in the Hair Dynamics
