6 months post op hair transplant-It’s look so much dandruff on hair and dry skin. Hair Still keep falling. (photos)

I have got hair transplants 6 months ago.now I start to see my hairs falling again and start to getting thinner. Where I was got new hairs that part is also start looking thinner. How long should I wait is also start looking thinner. How long should I wait more to see results? After 1 month of hair transplants I start to use a baby oil on my hairs see lots of hairs falling but then grow back again but now it’s fall again.
