Is shedding like this normal?

[Ziggyz123]

Hey, so I've been on fin for a year 3 months and never had the shed at the start of the treatment, but at one year had a huge shed. Now my hairline and behind it on the left side is like 40% thinner.. When I started it was just to keep what I have. Now my hairline is thinning and receding fast and it itches at times. The hairs are so weak and just fall out easily now..

My hair was CONSIDERABLY better before this treatment and I though positive replays were supposed to be seen at 1 year? I never thought my hair would ever look like this. I have like a strip of hair missing behind my hairline..
