About Us
Built by Trichologists. Backed by Experience.
Designed to Raise the Bar.
Three perspectives. One shared mission: to bring clarity, connection, and credibility to hair and scalp health—one practitioner, one client, one case at a time.
Why We Started The Hair Wire
For the Public (Clients/General Audience)
We created The Hair Wire to bring clarity, connection, and trusted answers to people struggling with hair and scalp issues.
Hair loss isn’t just cosmetic—it’s deeply emotional, often misunderstood, and rarely treated at the root. We saw firsthand how many people were dismissed, misdiagnosed, or stuck in a loop of trial-and-error. The three of us came together because we were tired of seeing people fall through the cracks. Each of us brings a unique lens—clinical, holistic, and generational—but we all believe in the same thing: real results come from understanding the full picture, not just the symptom.
The Hair Wire is where that understanding begins. We built this platform to help you access real education, real experts, and real care—so you don’t have to keep figuring it out on your own.
Raising the Standard in Trichology
For Professionals (Trichologists & Industry Practitioners)
The Hair Wire was born from three trichologists, three perspectives, and one shared mission—to raise the standard and support the people behind the practice.
What We’re Doing Here: If you’re in this work, you’ve probably felt it—disconnected training, outdated frameworks, and a total lack of mentorship. We’ve felt it too.
Between the three of us, we’ve studied, practiced, and taught trichology around the world. But even with all that experience, we kept hitting the same wall: a broken system that left professionals unsupported, overwhelmed, and often isolated. That’s why we created The Hair Wire. A hub for connection, credibility, and collaboration. Through our Faculty of Trichology, resource library, and practical tools, we’re here to help you deepen your practice and elevate your impact—without the burnout.
Whether you’re just starting out or decades into the work, this is your space to grow with integrity, support, and a clear path forward.
Meet the CoFounders
Three trichologists. Three unique paths. One shared mission—to raise the standard in hair and scalp health.
Together, we created The Hair Wire / Factually of Trichology to bring clarity, connection, and credible support to professionals and clients worldwide.
Sergio Cardona
Sector: Technical Foundations+
Niche: Business & Innovation
Learn More About Sergio
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.

Myth vs. Fact
Myth: Cutting your hair makes it grow faster.
Fact: Cutting doesn’t affect growth from the root — but it does reduce breakage, helping it look fuller, healthier, and preventing more breakage.
Myth: Dandruff means your scalp is dry.
Fact: Most dandruff is actually due to an overgrowth of yeast on an oily scalp — not dryness! Always get a proper diagnosis.
Myth: You can “train” your scalp to produce less oil.
Fact: Your scalp’s oil production is determined by hormones, hydration, not washing habits. Overwashing can make it worse.
Myth: Natural oils can fully replace conditioner.
Fact: Oils sit on the hair; conditioners penetrate into it. Oils are great, but they’re not a one-for-one substitute.
Myth: Stress makes your hair fall out immediately.
Fact: Telogen effluvium (stress-related shedding) usually kicks in about 8–12 weeks after a stressful event — so it’s often delayed and unexpected.
