Episode notes

Hair loss is a topic I’ve written about many times in the past few years, having experienced hormonal thinning myself. So I was keen to sit down with leading dermatologist Dr. Nicole Chiang to understand why our hair changes as we hit our 40s and 50s, and to discover the surprising impact that stress, weight loss, and hormones have on our hair health.

Expect lots of chat about:

Midlife Hair Loss: We explore the "perfect storm" of the 40s and 50s. As estrogen drops, the androgen influence becomes stronger, which can shrink hair follicles. Dr. Nicole explains why that "shrinking ponytail" happens and the medical-grade ways to fight back.

LED Therapy for Hair: Gimmick or game-changer? We get into the science of red light therapy for hair, why consistency is the only way to see results, and why a "comb" device might actually beat a "helmet" when it comes to reaching the scalp.

The Truth About "Ozempic Hair": We address the rise of GLP-1 medications and the hair shedding that often follows. Spoiler: It’s not the drug itself, but the rapid weight loss and nutrient prioritization that’s to blame.

Products & Ingredients Mentioned

Minoxidil: The gold standard for prolonging the growth (anagen) phase.
Eucerin DermoCapillaire Calming Urea Shampoo: Recommended for dry, itchy scalps.
Urea-based Serums: For locking moisture into the scalp skin.
Hairmax: Mentioned for their clinical studies on red light devices.
Protein & Iron: The non-negotiable "building blocks" (aiming for 1g of protein per kg of body weight).
