Key topics
Dr. Adriana Nicole Rosales describes her path from family medicine and Navy service to private practice, wellness care, aesthetics, and hair restoration.
Hair loss is not just cosmetic—it can cause anxiety, distress, and concerns about self-image.
Androgenetic alopecia is discussed as a common cause: testosterone can be converted into DHT, which damages hair follicles over time.
Other causes include autoimmune conditions, telogen effluvium, thyroid dysfunction, and postpartum shedding.
GLP-1-related hair loss may be associated with rapid weight loss, insufficient protein intake, and the body’s stress response.
Lifestyle and environmental stressors, including smoking, alcohol, and some chemical exposures, may contribute to cellular and follicle stress.
Identifying the underlying cause may involve a physical exam, lab work, a scalp biopsy, or referral to a specialist.
Hair-health basics include adequate protein, a nutrient-rich diet, and addressing factors that may put stress on the body.
Dr. Rosales discusses the limits of supplements such as biotin and collagen as standalone hair-regrowth solutions.
She explains exosomes as cellular communication packets and discusses their use in hair-restoration protocols.
Aim for adequate protein, especially when losing weight or using a GLP-1 medication.
Avoid rapid weight loss without medical supervision.
If hair shedding is sudden or diffuse, discuss possible underlying causes with a qualified clinician.
Ask your clinician whether thyroid function or nutritional deficiencies should be evaluated.
Protect your scalp from sun exposure, especially if you have thinning hair or a visible part.
Seek support if stress is affecting your well-being or contributing to distress about hair loss.

Dr. Adriana Nicole Rosales shared pacificclinic.com and Pacific Clinic Bellevue’s Instagram and Facebook accounts as ways to connect.- Did you close your rings, hit your protein macros, do your 30-minute sauna… and still feel worse than ever?
This week it's just you and me. I recently overheard two young guys in a sauna insisting that 30 minutes was the rule — no less, no more. And it got me thinking about how many of us are living someone else's health protocol.
Influencers are selling attention. Studies describe populations, not you. Neither one knows your DNA, your values or what actually feels good in your body. So we end up ticking boxes, chasing numbers, being "good" all week and then swinging to the other extreme — the binge, the booze, the 22K punishment run. I call it the licensing effect, and it's the reason health starts to feel like a chore.
In this episode I share:
- Why influencer routines and research protocols were never designed for you
- How numbers on your watch and food labels create a disconnect from how health should feel
- The binge-restrict pendulum and how to find your middle ground
- What a pregnant client's KFC cravings were really telling her
- Why 5 minutes in the sauna might serve you better than 30
- How to become your own "N of 1" and build health you actually look forward to
This picks up where last week's Pleasure Principle episode left off. If you missed it, it's the perfect companion.
