I've been cutting my hair for a while so I'm very aware of my hairline and 1 month ago I noticed that it was receding, 2 weeks ago it started receding faster and now it's like this. But I had an accident 2 months ago and ended up in the hospital , and due to that I had stress after that period/ high bp. Could that be a contributing factor ? My father started losing his hair when he was 35.
