Meet Our Consultants

Gene Gaspar, Transplant Image Consultant

Gene began losing his hair at 23 years of age. Even though he felt young, the aging process was on a fast track because he was balding at a young age. He researched his options and made the decision to try a non-surgical hair system. As the surgical procedures advanced in technology, he decided to go with natural growing hair and did away with the hair system. Gene started researching hair transplant companies, and in 1998 had his first hair transplant procedure. He was so impressed with his result, that he became a consultant for the company and physician.

Gene had a second procedure in 2007 to add more density to his existing transplanted areas. “It’s by far the best thing I’ve ever done and I would recommend it to anyone trying to maintain a more youthful appearance,” says Gene. “It’s been an amazing journey, and it’s a wonderful feeling to help people meet their expectations.” Gene has been a hair restoration consultant for the past 20 years and is working with National Hair Centers as one of three image consultants, financing specialist, and laser therapy expert. Gene’s knowledge on all aspects of the hair transplant industry including FUT, FUE, Non-prescription medications, Prescription Medications and Low-Level Laser Therapy (LLLT) is unsurpassed. If you need help with your hair loss, please call Gene at (425) 633-5458.

I was experiencing hair loss because of illness and surgery. I met with consultant Gene who was very professional and knowledgable. He explained the options I had to help with my hair loss. I choose the low light laser therapy cap and it has done wonders. My hair is healthier and looks and feels fuller. What a difference. A big thanks to Gene G.

Allison M., Scottsdale AZ

I have been going to NHC for ten years, and there are basically three things that keep me coming back. First of all, they listen to me, giving me their undivided attention as I explain what I want. Secondly, Sean is especially helpful and knowledgeable, always following through when he says he will do something that I have requested. Finally, all of the employees are courteous and make me feel like a valued customer. I will continue to avail myself of the excellent products and services at NHC.
