My Pet Labrador is having hair loss 2-3 times in a year. He is only 1 year old. Could you suggest any way to prevent this.
It's called shedding or blowing coat. It's normal and actually good for the coat to get rid of the old so the new can grow in.

You can't prevent it. Only thing that helps a little is to brush them. Sometimes when they blow their coat you can see the tufts drop off as they walk.
You get used to dog hair as accessory and condiment.
but its shedding heavily. Some parts of him have no hair.
Yes, they can get down to bare skin at times when they blow coat. Labs shed heaviest in the spring and fall, blowing out their coat for new coat growth. My yellows have just started blowing their winter coats. They're blowing out their soft, downy undercoat which has kept them warm during the winter. They won't need it during the summer, so they blow it out.
All I can add is, if you are concerned and think the shedding is abnormal, then you should have the dog checked by your vet. Maybe have a thyroid test done to make sure the shedding you're seeing is not caused by a low thyroid.
We can't see your dog and see how/what it's shedding. Labs are notorious shedders as the cartoon I added previously showed.

Does blood comes when they shed their hairs?
To get better answers on here you could post some pictures, it is hard to tell what kind of hair loss you are describing without seeing the dog.
