Skinside Out

Hair loss can happen for many reasons, and finding the right treatment starts with understanding the cause. Dr. Zain Husain, Heather Murray, and Courtney Carroll break down the most common types of non scarring alopecia, including pattern hair loss, alopecia areata, telogen effluvium, anagen effluvium, traction alopecia, and trichotillomania. The team discusses how genetics, hormones, stress, illness, medications, and hairstyles can contribute to hair loss. They also explain common diagnostic approaches and explore treatment options such as minoxidil, finasteride, growth factor serums, PRP, red light therapy, steroid injections, and hair transplantation. The conversation covers important medication considerations, why hair loss treatments can take months to show results, and why identifying the correct type of alopecia matters. They also highlight the importance of recognizing potential triggers, protecting hair follicles from repeated tension, and seeking guidance from a board certified dermatologist. 00:00 Understanding non scarring alopecia 00:30 Androgenic alopecia and pattern hair loss 01:30 Diagnosing pattern hair loss 03:00 Minoxidil and treatment options 04:30 Minoxidil safety around pets 05:00 Finasteride risks and considerations 07:30 Growth factors, exosomes, and PRP 09:00 Red light therapy for hair growth 10:30 Hair transplantation 11:00 Why early treatment matters 12:00 Alopecia areata explained 12:45 Steroid injections and treatment options 14:00 Treatments for more severe alopecia 15:00 Diagnosing alopecia areata 16:00 Telogen effluvium and stress related shedding 17:00 Hair loss after illness and weight loss 18:00 Understanding temporary hair loss 20:00 Anagen effluvium and chemotherapy 21:30 Traction alopecia and tight hairstyles 23:00 Trichotillomania and repetitive hair pulling 25:30 Vitamin deficiencies and thyroid disorders 27:00 Why the right diagnosis matters

Dr. Zain Hussain and the Noor Dermatology team unveil the structured Noor Longevity Program, a personalized, year-long partnership focused on improving healthspan—living well longer—by optimizing internal health and outward skin confidence. Joined by PA Heather Murray, esthetician Courtney Carroll, and consultant Dr. Fatima Syed (Duke internist with endocrinology training), they discuss evidence-based longevity, lifestyle foundations (nutrition, sleep, stress, exercise), and individualized use of labs and biomarkers beyond routine primary care, including CRP, insulin resistance measures, lipoproteins, and hormones. They emphasize safety and supervision amid social media misinformation, addressing risks of poorly managed HRT and unregulated peptides, while noting potential benefits of GLP-1s and metformin when monitored. The program includes a pre-consult with advanced labs, a one-hour physician consult and blueprint, quarterly check-ins, monthly aesthetic treatments, repeat labs, and direct access to the care team. 00:00 Noor Program Teaser 00:44 Meet Dr Zain 01:52 Meet The Team 04:01 What Longevity Means 05:50 Personalized Goals 08:06 Hormones And Women 09:52 Evidence Over Hype 11:26 Lifestyle Foundations 12:12 Skin As Health Mirror 15:53 Biomarkers Deep Dive 18:36 Beyond Routine Labs 20:30 Hormones GLP1 Peptides 26:53 Optimization Personas 29:14 Choosing Safe Providers 30:34 Program Walkthrough Setup 30:50 Program Overview 31:55 Consultation Blueprint 32:47 Check Ins And Treatments 34:19 Advanced Lab Testing 35:02 Who The Program Helps 36:20 Primary Care Partnership 38:15 Access And Accountability 40:16 Customization And Team Care 42:19 Men And Aesthetics Shift 46:20 Safe Supervised Longevity 48:11 Rapid Fire Q And A 48:56 Philosophy And Wrap Up 51:00 Podcast Outro And Links

Peptides are everywhere, but how much do we actually know about the oral and injectable versions? Dr. Zain and Courtney continue their peptide conversation by exploring collagen supplements, GHK Copper, BPC 157, ipamorelin, and CJC 1295. They discuss what the current evidence shows, where research is still limited, and why the way a peptide is sourced and delivered matters. The conversation also covers hormone related peptides, potential risks, FDA approval, compounded products, online pharmacies, and the importance of working with a physician instead of self medicating. Dr. Zain and Courtney also break down the difference between established, emerging, and investigational treatments and explain how they evaluate peptides based on their intended goal, supporting evidence, method of administration, and known and unknown risks. They finish by discussing marketing claims surrounding aging and longevity and why improving healthspan may be more meaningful than simply extending lifespan. 00:00 Introduction to oral and injectable peptides 01:00 Collagen peptides and the evidence 03:00 GHK Copper 05:00 BPC 157 and tissue repair 06:00 Ipamorelin and CJC 1295 07:00 Hormones and potential health risks 09:00 FDA approval and experimental peptides 11:00 Understanding the evidence ladder 13:00 Evaluating peptide marketing claims 15:00 Healthspan versus lifespan 16:00 Questions clinicians should ask about peptides 18:00 Where peptides could fit into future healthcare 20:00 Balancing innovation with patient safety 22:00 Taking a closer look before using peptides

Peptides, growth factors, and exosomes are becoming some of the biggest buzzwords in skincare, but what do they actually do? Dr. Zain and Courtney break down the differences between these powerful molecules, how they communicate with skin cells, where they come from, and what the current clinical data tells us. The conversation covers collagen supporting peptides, growth factors involved in wound healing and tissue repair, and exosomes as a delivery system for different signaling molecules. They also discuss sourcing, the importance of clinical testing, PDRN, and why the formulation and stability of these ingredients matter. Dr. Zain and Courtney also share some of their favorite products, including SkinMedica TNS, Neocutis, Revision, and Nectifirm. They explain how procedures such as microneedling, RF microneedling, and lasers can enhance the delivery of these ingredients into the skin, and why combining different products may help maximize results. The episode wraps up with a discussion about the importance of looking critically at skincare claims and relying on meaningful clinical data rather than marketing alone. 00:00 Introduction to peptides 01:00 How peptides work with skin cells 02:00 Growth factors and cellular signaling 03:00 What are exosomes? 04:00 What peptides can do 05:00 Where peptides come from 07:00 Clinical data on peptides 08:00 Understanding growth factors 10:00 Clinical evidence for growth factors 11:00 Favorite growth factor products 12:00 Introduction to exosomes 14:00 Why exosomes are so delicate 15:00 Human derived vs plant derived exosomes 17:00 PDRN and emerging skincare ingredients 19:00 Exosomes vs growth factors 20:00 What the clinical evidence says 21:00 Enhancing skincare delivery 22:00 Combining peptides, growth factors, and exosomes 24:00 Why clinical data matters 25:00 Looking ahead in skincare

Skin Side Out Episode 70 explores the connection between skin health, metabolism, aging, and longevity. Dr. Zain, Heather, and Courtney discuss how dermatology is moving toward a more comprehensive approach that considers what is happening inside the body, not just what appears on the skin. The conversation covers regenerative medicine, collagen, GLP 1 medications, muscle loss, metabolic health, inflammation, lab testing, and how changes in the body can show up through the skin. They also discuss the importance of working with a primary care physician, being cautious with emerging treatments such as peptides and exosomes, and understanding the difference between promising treatments and those backed by strong evidence. The episode wraps up with five pillars of healthy aging: sun protection, preserving muscle and bone, optimizing metabolic health, reducing inflammation and environmental damage, and using aesthetic treatments thoughtfully. They also emphasize sleep, mental health, healthy routines, and focusing on becoming the best version of yourself rather than trying to look like someone else. 00:00 Skin, metabolism, and longevity 01:00 Understanding aging and the future of aesthetics 02:00 Taking a whole body approach to dermatology 05:00 Optimizing health before illness 06:00 What regenerative medicine means 07:00 Stimulating collagen and improving skin health 09:00 Regenerative medicine and PRP 10:00 What the skin can reveal about internal health 13:00 A skin finding that revealed severe metabolic problems 15:00 The importance of primary care 16:00 How aging affects collagen, muscle, bone, and volume 18:00 GLP 1 medications and muscle loss 20:00 Metabolic health and longevity 23:00 The importance of tracking health markers over time 25:00 Looking beyond standard lab testing 28:00 Challenges within the healthcare system 29:00 The controversy surrounding regenerative treatments 31:00 Understanding evidence, safety, and experimental treatments 33:00 Researching products and understanding what is actually being used 34:00 The future of dermatology 36:00 Personalized and integrated care 37:00 The five pillars of healthy aging 38:00 Preserving muscle and bone 39:00 Metabolic health, inflammation, and sleep 41:00 Using aesthetic treatments thoughtfully 42:00 Mental health and overall wellbeing 44:00 Small habits that can improve daily life 46:00 The future of longevity care 47:00 Launching a longevity program at Noor Dermatology Aesthetics 48:00 Closing thoughts
