Transplanted hair losing density after HT done 7 years ago

[Addendum]

Hi, I’ve just joined here.

I was a Norwood 6 and had a hair transplant 7 years ago.

I was pleased with the result, and though I didn’t have enough hairs transplanted to cover the crown of my head, the front part of my head was fairly well covered. I would have had another HT later to add more density but couldn’t afford it.

In the past few weeks, I’ve noticed that the density of the transplanted hair has diminished, and I can see through to my scalp. I’m hoping that this is due to the telogen phase of the hair cycle rather than the transplanted hairs beginning to fall out permanently. I read that the telogen phase comes every 6 or 7 years so one is due for me around now.

In the past 5 months (until I discovered the hair loss) I had been using dry shampoo and also volumizing mouse on my hair, and maybe this has something to do with the hair loss.

Also I have been drinking whey protein shakes each day for about 8 months, and maybe this is also is connected to the hair loss. I read that whey protein can have negative affects on hair growth.

I don’t think the hair loss is due to seasonal shedding, as I haven’t noticed any such shedding to a great extent—just a few stray hairs now and then in the sink.

The current lack of density problem looks as if it could be more serious. I hope not.

I’d be grateful for any advice.
