Firefighters, police officers, employees from the legal department, even the San Marcos mayor said "bye, bye" to their hair on Friday.
"It feels different! That's for sure, but I'm enjoying it, it'll be fine," said Mayor Daniel Guerrero
On a big TV screen, 5-year-old Waylon Malone and his mom Stacy, a former city employee, watched via Skype.
They're at St. Jude Children's Research Hospital in Memphis, Tennessee.
Waylon is being treated for Neuroblastoma, a cancer he's had since he was 3.
His dad Chris stays in San Marcos to take care of Waylon's twin sister Morgan and throughout it all his wife's former co-workers have been helping as much as they can.
"For the last 2 years, even though she hasn't worked here, they've supported our family," Malone said.
Chris says this is the third time his son has lost his hair during treatment. Since he's a little older, it's bothering him this time.
"My wife Stacy said that he's kind of upset about losing his hair. So next thing you know we've got a fundraiser where everybody's cutting their hair off so it's great," he said.
Mayor Daniel Guerrero was the first to go under the clippers.
And he knows all too well what Waylon is going through.
Guerrero also had cancer when he was just 5 years old.
"I can certainly relate to what Waylon feels like, knowing that he's lost his hair but we're determined that...it's just hair. It's what's inside of you...and the heart of the community that really matters," Guerrero said.
And it wasn't just the men getting shaved. Renate Yanity works for the city legal department. She's a cancer survivor as well. She says the part where you lose your hair feels like you're losing control.
"I can't even imagine what it must feel like for a young child to just feel that happening and not having any control and to know there's more coming," Yanity said.
The city tells us the total number of shaved heads today ended up being 65 employees.
And for Waylon's family, the good people of San Marcos raised $11,000.
