Hi Mr. lybrate-user,
First we need to assess the cause for your hair thinning. If there is any medical condition causing this thinning, like androgenic alopecia, we need to treat the underlying medical condition. If there is no medical condition and your hair is naturally the way it is, there is nothing much we can do. We could try PRP treatments and mesotherapy
, but the results will be variable. This is my honest opinion. Take care.
