866: The Future of Hair: Stem Cells, Hair Cloning, and Regenerative Restoration with Dr. Richard Chaffoo Sep 15, 2026

Show notes

Hair loss is more than cosmetic—it can dramatically affect confidence, identity, and how we perceive aging. In this episode of Beauty Bytes with Dr. Kay: Secrets of a Plastic Surgeon, I am joined by Dr. Richard Chaffoo, a nationally recognized triple board-certified plastic surgeon with more than 30 years of clinical experience and a special focus on hair restoration and regenerative medicine.

We break down what is actually happening inside the hair follicle as hair begins to thin and why early intervention matters before chronic inflammation, miniaturization, and fibrosis permanently compromise the follicle. Dr. Chaffoo walks us through today’s treatment spectrum, from oral minoxidil and finasteride to dutasteride, PRP, microneedling, red-light therapy, and his approach to combined regenerative therapy. We also discuss why hair restoration should go beyond simply prescribing a pill or performing a transplant—and why evaluating scalp health, nutritional deficiencies, hormones, and the biological environment surrounding the follicle is so important.

Then we dive into the future of hair science. Dr. Chaffoo shares his experience working with researchers at Stemson Therapeutics to create human hair follicles from pluripotent stem cells and successfully grow human hair in preclinical models. We discuss the possibility of hair cloning, follicle banking, regenerating the entire multicellular hair-follicle niche, and a future where patients may be able to preserve their own follicles or generate new ones rather than relying solely on a limited donor supply.

Could hair transplantation eventually become obsolete? From stem-cell-derived follicles to regenerative treatments designed to rescue thinning hair before it is permanently lost, this conversation explores how rapidly the science of hair restoration is evolving—and what may be possible in the decade ahead.

865: Summer Skin Recovery: Repairing Your Barrier for Fall Sep 11, 2026

Show notes

Summer heat takes a toll on your skin. In this week’s podcast, we’re talking dryness, irritation, and the breakdown of your lipid barrier. This natural barrier is your shield against environmental stressors, and when it’s disrupted, inflammation follows. As the season shifts, it’s the perfect time to repair and restore. We’ll cover why ceramide-rich moisturizers matter, how hydrating soaks help replenish, and why it’s smart to ease up on exfoliation. Plus, we share tips on diet, recovery treatments, and why end-of-summer peels set you up for glowing, resilient skin heading into fall.

864: The Mitochondrial Masterclass: Hyperbaric Oxygen, Methylene Blue, and GABA with Dr. Scott Sherr Sep 09, 2026

Show notes

Are you feeling constantly "wired and tired" or struggling to recover from chronic stress and inflammation? In this episode of Beauty Bytes, I am joined by Dr. Scott Sherr, a board-certified internal medicine physician and a leading specialist in hyperbaric medical oxygen therapy (HBOT). Dr. Sherr is the Chief Medical Officer of Transcriptions and a pioneer in Health Optimization Medicine, a foundational framework that utilizes metabolomics to assess and heal your cellular machinery rather than simply band-aiding disease. We dive deep into the science of hyperbaric therapy, breaking down why varying atmospheric pressures are required depending on whether you are targeting the central nervous system or systemic wounds. Dr. Sherr explains that flooding the body with oxygen creates reactive oxygen species, meaning your mitochondria must be fully optimized with the right antioxidants to actually leverage the benefits of HBOT. We also challenge everything you thought you knew about depression and anxiety, exploring why a deficiency in GABA—your brain's primary inhibitory neurotransmitter—is far more likely to cause your 120,000 racing thoughts a day than a lack of serotonin. Finally, we discuss the incredible benefits of low-dose methylene blue for instantly boosting mitochondrial capacity, and why this compound is particularly transformative for women navigating the steep estrogen and progesterone drops of perimenopause.

862: Reversing Cellular Senescence: GPX4, Ferroptosis, and Adaptive Senotherapeutics with Dr. Frederick Beddingfield Sep 02, 2026

Show notes

Are you fascinated by the molecular science of aging and senescence? In this episode of Beauty Bytes, I am joined by Dr. Frederick Beddingfield III, the CEO of Rubedo Life Sciences, a physician-scientist, and a former senior leader at Allergan. We focus on the cutting edge of longevity and how Rubedo is developing adaptive senotherapeutics to reverse cellular aging and extend healthspan. Dr. Beddingfield explains the science behind their lead drug, RLS 1496, which targets the enzyme glutathione peroxidase 4 (GPX4) to regulate ferroptosis, an iron-dependent cell death pathway. We discuss how this drug not only eliminates toxic senescent cells but also acts as a "redox reset" for aged cells, reducing their biological age by improving mitochondrial function and autophagy. We also explore their groundbreaking human clinical trials, which demonstrated a 50% reduction in precancerous actinic keratoses in just four weeks without causing skin irritation. Plus, Dr. Beddingfield shares his personal biohacking stack, including low-dose rapamycin, fisetin, and quercetin.

860: Dr. Koji Tanabe on Reprogramming Aging: iPSCs, Longevity, and Cellular Rejuvenation Aug 25, 2026

Show notes

In this episode of Beauty Bytes with Dr. Kay: Secrets of a Plastic Surgeon, I am joined by Dr. Koji Tanabe, a leading stem cell scientist, founder and CEO of iPeace, and one of the researchers behind the landmark development of human induced pluripotent stem cells, or iPSCs. Dr. Tanabe breaks down the science of Yamanaka factors and explains how mature cells can be reprogrammed into a younger, pluripotent state with the ability to develop into many different cell types. We explore how iPSC technology differs from traditional stem cells, PRP, exosomes, and other regenerative treatments, as well as why creating and quality-checking these cells outside the body may offer important advantages over attempting cellular reprogramming directly inside the body. Dr. Tanabe also shares how iPSC-derived cells are being explored in regenerative applications involving heart failure, Parkinson’s disease, spinal cord injury, and other areas of medicine. We dive into the future of personalized cell banking, why he believes it may be beneficial to preserve cells while you are healthy, and how iPSC-derived factors, or iPSF, are being explored for skin rejuvenation, hair restoration, and systemic longevity treatments. The iPSF treatments discussed in this episode are currently available only in Japan and are not available in the United States at this time due to differences in regulatory standards. From cellular aging and DNA mutations to epigenetic clocks, regenerative medicine, and the difference between lifespan and healthspan, this conversation offers a fascinating look at how cellular reprogramming could change the way we approach aging, disease, and the future of personalized medicine.

Clarification: During the discussion of iPSC-derived therapies for heart failure, the conversation referenced the possibility of creating patient-specific, autologous iPSC-derived cells. The currently approved application discussed in this episode is allogeneic, not autologous. Dr. Tanabe was referring to the potential for iPSC technology to be developed for personalized autologous applications.

Guest Information: Dr. Koji Tanabe is a stem cell scientist and the founder and CEO of iPeace. He spent eight years conducting research at Kyoto University in Nobel laureate Dr. Shinya Yamanaka’s laboratory and was the second author on the landmark 2007 paper describing the generation of human induced pluripotent stem cells.
