Hair loss issues

Hi ladies!

I’m hoping someone has had the same issue I am having now. After having my baby in July 2018, a few months after I was having severe itchy scalp and my head was getting red. In April 2019, I went to a dermatologist who said it was seb. dermatitis. After many topical ointments and shampoos, she then suggested that it could be hair loss as she now sees many red bumps on my scalp. She gave me an antibiotic but I’m still breastfeeding (16 months pp) and it didn’t seem to work well either. I just don’t know what to do. Did anyone at all have this issue? Is this even linked to postpartum anymore? I am so self conscious about it as right at my hairline you can see so many red bumps. It takes forever to get into a dermatologist to seek a second opinion but maybe I should schedule something...thoughts? Advice?

I am still taking my prenatal and have started biotin gummies to see if that would help.

Thanks in advance! ❤️
