I’ve gone down the rabbit hole of scarring alopecia. It’s very unlikely. Like 1% that your hair loss is from that especially as you already have a receded hairline indicating androgen sensitive hairs. If you want to rule out scarring alopecia for your peace of mind, go to a dermatologist specializing in hair loss and push for a scalp biopsy in the affected area.
But even then, it’s not definitive. I got a lichen Planopilaris diagnosis from a scalp biopsy but a major specialist in scarring alopecia examined me closely and said that it’s unlikely I have it. He felt with his hands and used microscopes too. I think he mentioned you can choose a random full head from the streets, do a scalp biopsy, and one hair can have lichen Planopilaris show up in the biopsy. That’s because male pattern baldness and LPP have similar inflammation and fibrosis.
so even scalp biopsies can lead you astray. What you need to look for is: inflammation, burning pain, rough skin, hair can easily be pulled out, and hair loss continually happening in that area. And if your biopsy shows lichen planopilaris, that’s what it is. Better yet two biopsies would be definitive.
