AGA GuidelinesThere is a large void when it comes to guidelines for the treatment of androgenetic alopecia, specifically FPHL. In this final lesson, we bring it all together, with recently published 2025 guidelines that help to fill that void and provide worldwide guidance, reflecting common practice in the UK and elsewhere.

Platelet Rich Plasma (PRP)Some clinicians swear by it, others have had a less favourable experience with it. So, what’s the low-down on PRP for FPHL?

Low Level Laser Light Therapy (LLLT)Everyone’s talking about it. But should we be recommending it? And if so, which devices? How often? Let’s review the recent evidence.

Low Dose Oral Minoxidil (LDOM)There is a lot of hype around LDOM and it is increasingly used for all types of alopecia. But, what doses should we use? Do we need to monitor it? And what are the side effects? We summarise the evidence here.

When should we do blood tests? Which tests? And how?This lesson summarises consensus views on blood tests for FPHL and how to do testing when required. Based on dermatology as well as endocrinological guidelines and papers, we bring summarise the salient points.

Today on Dermatology Snapshots, we are looking at the New England Journal of Medicine 2025 Clinical Practice review on Female-Pattern Hair Loss by Dr. Elise Olsen. It’s a condition that affects up to 12% of women in their thirties, and over half of women over seventy.
