@Hephaistos1002 just seen this post, good for you man. WTF is going on here, this thread is 6 pages long and barely anyone points out that this person who is just 19 years old doesn’t even appear to have hairloss!!!!!
@MrSnow Your hair looks perfect, it is dense and healthy. You have dark coloured, naturally fine hair and a light scalp which highlights the contrast between the two. This is perfectly normal. The light scalp against the dark hair will look more dramatic when hair is wet, or greasy and under certain lights it is really pronounced. Even more so when photographed through a phone. I am much older than you at 42 but have very similar characteristics - I thought I was going bald in my 20s because my hair looked like yours, guess what, it didn’t change! I do not see anything that suggests you are losing hair. Check your family history and if balding is common, see a dermatologist. PM me if you want.
PS. You definitely need help to stop catastrophic thinking, trust me I have been there.
All the best.
