Building fierce cultures of Connection.
H.E.L.L.O. is the smallest word with the biggest superpower:
Connection. Conversations. Purpose. Belonging. Performance.

Infectious Behaviour is a bold movement ignited by Mel - electrifying motivational speaker, magnetic MC, and unapologetic truth teller.
Connection. Conversations. Purpose. Belonging. Performance.
Connection. Conversations. Purpose. Belonging. Performance.
What’s the real secret to Connection?
Mel teaches leaders what hairdressers have always known: connection is a behaviour, not a buzzword.
What’s the real driver of high-performing cultures?
It isn’t another initiative, engagement platform, or leadership buzzword. It’s human connection.
For over 18 years, Mel has studied thousands of real conversations in workplaces, community settings, and high-pressure environments where trust matters most. The insight is consistent: when people feel seen, heard, and valued, communication improves, collaboration strengthens, and performance follows.
Today’s organisations are facing disengagement, burnout, and fractured culture. These aren’t operational problems they’re relational ones.
Through Mel’s Magic of H.E.L.L.O. keynote, Mel equips leaders and teams with practical, evidence-informed behaviours that build trust, elevate wellbeing, and create cultures of belonging immediately and sustainably.
If your ready to reconnect your people, Mel’s ready…
“From the streets to the stage Mel brings raw stories and radical frameworks that shatter disconnection, ignites belonging and demands cultural change”
“We were delighted to have Mel Alsemgeest as MC for our It's a Hairy World book launch party. From planning to the final thank-you, Mel was prepared, energetic and engaging. She connected beautifully with the crowd, kept the event running smoothly and used her hair industry insight to make every moment relevant. We’d happily recommend her for future MC roles!”

Electrifying Motivational Speaker
Have you noticed that when you’re having one of those days, and someone simply says hello, how did that make you feel?
Mel has built her life around that truth. From the salon chair to the streets, from prisons to boardrooms, she’s discovered that the smallest word can carry the biggest punch.
As a kid, she was convinced she was Wonder Woman saving the world one imaginary adventure at a time. Turns out, she wasn’t wrong. Today she brings that same superpower to real life, showing us how one simple hello can shift culture, spark belonging, and change everything.
Magnetic MC
Mel Alsemgeest is the MC who electrifies events. She doesn’t just keep things moving she plugs the whole room into a current of energy and connection. With her Wonder Woman presence, razor-sharp humour, and radically human touch, she bridges audience and stage so that every moment feels alive.
She knows when to lift the voltage and when to ground the room, giving events rhythm, flow, and spark. Speakers shine brighter, audiences buzz longer, and organisers relax knowing the power is in safe hands. Mel doesn’t just host events - she energises them.
Street Level Humanity
For over 18 years, Mel has provided thousands of street-level haircuts in parks, shelters, drop-in centres, and community spaces. Not to “fix” people but to see them. A haircut is the doorway, connection is the work.
That same human-first approach now lives inside women’s prisons, where dignity, trust, and belonging are often stripped away long before freedom. These conversations don’t end in the chair. They continue through The Hair Therapist Podcast and onto stages, where lived experience becomes learning. The message is simple and fierce: real change begins with connection, deepens through conversation, and restores purpose and belonging one H.E.L.L.O. at a time.
