Professional Education in Hair & Scalp Health
Evidence-informed education for professionals committed to advancing the understanding of hair biology, scalp health, and trichological care.
The Faculty of Trichology was built on the belief that no single profession has all the answers.
Hair and scalp health are influenced by many disciplines, which is why we bring together hairstylists, trichologists, dermatologists, nutrition professionals, medical and wellness practitioners, researchers, educators, and industry leaders in one collaborative community.
Through evidence-informed education, roundtable discussions, and open professional dialogue, we're helping bridge the gaps between professions to advance knowledge, strengthen collaboration, and raise the standard of trichological care.
Because the future of trichology is built together.

Sergio Cardona brings generational expertise to The Hair Wire as a second-generation Trichologist trained under the uncompromising standards of his father, a pioneer in Puerto Rican barbering and trichology education. His path started early—he began studying trichology in high school, working side-by-side with his father, and eventually earned his certificate only after completing a Biology degree and proving he was ready to carry the family legacy forward.
Rooted in both scientific training and lived tradition, Sergio blends textbook knowledge with hands-on mastery. He’s taught hundreds of professionals across Latin America and beyond, building a reputation for his practical, no-fluff teaching style and sharp clinical eye.
He also runs a successful private practice, where his work spans everything from complex diagnostic cases to mentorship for emerging trichologists. Over the years, he’s built an extensive training library filled with real-world, case-based insights—always centred on what actually works in practice.
At The Hair Wire, Sergio leads the charge in technical education, protocol development, and practitioner case reviews. His role in the Faculty of Trichology anchors the curriculum in tradition, clinical rigour, and clarity.
His gift? Teaching trichologists how to see—not just with their eyes, but with discernment sharpened by decades of experience. He honours the roots of this work while boldly evolving it for the next generation.

Bissan is a Certified Trichologist with over 10 years of experience in the hair loss industry. She also holds a certification as a Functional Medicine Health Coach and has earned a Master’s in Biotechnology and a Bachelor’s in Biochemistry. Passionate about health and wellness, she integrates her scientific expertise with holistic approaches to address the root causes of hair and scalp disorders, rather than simply masking the symptoms. Her philosophy centers on achieving healthy hair by treating underlying imbalances within the body, creating long-lasting results.
Bissan has worked in Dubai, California, and now Florida, and she serves clients worldwide through virtual consultations. As an educator and the Director of Education at the Holistic Practitioners of Trichology, she teaches and mentors future trichologists, providing advanced training to elevate industry standards. Her career highlights include contributing to innovative research at Stanford University and pioneering Scalp Micropigmentation (SMP) with over 500 successful cases, including high-profile clients.

Her gift? Bridging science and soul. Helping professionals see the bigger picture beneath the follicle. And reminding us that healing the scalp often begins with rebalancing the system behind it.

Kerri Jarrett is a Certified Trichologist with over two decades of experience in clinical hair and scalp care, advanced cosmetology, and education. She’s trained extensively in trichological diagnostics, scalp neurology, and hair loss treatment—while also diving deep into the psychosomatic and behavioural patterns that show up through the hair.
Her approach is equal parts science, strategy, and self-awareness. Kerri doesn’t treat hair loss at the surface—she reads the patterns, the person, and the body behind it. With a background that bridges trichology, somatic practices, and cognitive therapies, she’s known for her ability to connect hair symptoms to deeper root causes, both physical and emotional.
Kerri is also a serial entrepreneur and creative director, known for building brands and educational tools that are both clinically credible and deeply human. She’s the founder of multiple businesses, including her intention-driven jewelry line, Sentimental Gems, and now serves as the strategic and creative lead at The Hair Wire.
At The Hair Wire, she oversees curriculum design, practitioner development, and brand positioning for the Faculty of Trichology—offering grounded, real-world training for trichologists ready to go deeper and grow bigger.
Her gift? Translating complexity into clarity. Helping trichologists understand the “why” beneath the symptom. And reminding everyone that hair never lies—it’s always telling a story, if you know how to listen.
