Dermatologist recommendations? Hair thinning, need to examine scalp + need advice.

TLDR: Searching for dermatologist to find cause of hair thinning, and for scalp examination. Not someone dismissive, i need to talk to someone professional please. 🙏

Hello everyone. 19M, noticed thinning around my temples and overall quantity of hair reduced this year. I don't wanna lose it all young, and while stress and poor nutrition may be a part of it, I want an actual diagnosis of the exact problems.

My friend went to one and got surface level advice, has anyone got experience with a dermatologist who actually listens whom you would recommend? Preferably in the North, otherwise it's still okay.

I want to find the exact issues and tackle them asap with promising results. I want someone who is not dismissive and instead thoroughly examines my scalp, finds the exact cause(s) and doesn't tell me to just shave it off.

This is quite vulnerable and I'd greatly appreciate your help. Thank you.
