Basically the title. I cut my hair today and noticed this big reddish brownish? spot on my head. My hair has been long for years so I never would've noticed anything. I immediately went into a full blown panic attack when I saw this.

Does anyone know what it is? Or does anyone else have it?

I'm trying to make a dermatology appointment ASAP :(
