Welcome to Color Theory
Hi! I am Heather Layne and I am a professional hair artist with over 15 years of experience.
I have had a passion for the beauty sciences since I was young, and am privileged to have found a career that feels like a true calling. I am professionally trained and certified in multiple extensions, color, cutting, and product services, and have had the honor of working alongside some of the most talented stylists in the industry.
My one and only goal is your absolute satisfaction. I aim to provide every client with the best possible experience… free of waiting, rushing, double-booking, and complete with the 5-star experience you deserve. When you are in my chair, you and your hair have my complete and undivided attention. I take pride in making people feel comfortable and truly heard, and that is a trait I proudly bring with me into my business.
Please feel free to contact me with any questions you may have. I look forward to meeting you!

Hello! I’m Kasey McCarthy, and have currently been licensed in cosmetology in Las Vegas since October of 2021.
Ever since I was little I have been super passionate with anything hair related, and shortly after I graduated high school I attended Academy Of Hair Design. After becoming licensed, I continued my education and worked with Color Theory.
When I’m not doing hair I’m either playing with my fur babies Hazard & Hassel, binge watching a tv show, or reading a book.
Besides doing color and highlights, my favorite thing about my career is getting to know all of my clients. I would love to see you in my chair!

Hi! I'm Michelle Garrett. With over 8 years of experience, I have a serious love for beautiful hair, and a slight obsession with making your color look effortlessly expensive.
l've done hair everywhere from Oahu Hawaii to San Diego, and now I'm bringing my skills and good vibes to Las Vegas!!
My specialty? Lived-in color + effortless cuts!
Think dimensional, low-maintenance, grow-out-friendly hair that looks gorgeous for months.
I'm all about enhancing what you've got, creating hair that feels like YOU, and making your salon time feel like a little escape. Come sit in my chair, spill the tea, and let's make your hair the best part of your day!!

Hey! I’m Cassandra… I have been a hairstylist for over two decades. My passion for hair has continued through the trends, with training from an array of industry brands. I want to bring you a custom look that you feel confident in and complimented on.
When I am not behind the chair, you can catch me gardening. I love the challenge of growing my own vegetables in this arid climate.
I look forward to having you in my chair!
