Sonia is a true master when it comes to hair. She was able to give me a beautiful color that will be able to withstand longer time between cuts. Also she’s the first stylist to not want to chop inches off my hair. Aside from that she’s funny, personable, and has a lot of knowledge. You won’t go wrong in her hands. Already figuring out when to schedule my next appointment.

Clean friendly environment. Zach was so helpful to the stylist doing my hair. The product used felt light and smelled amazing in my hair.

Stacia is amazing! Best haircuts ever. Pricey, but worth it. Free bang trims. Convenient locations, cool vibe, excellent attention to safety protocols.

Exactly what I wanted! Bridgette was precise and listened to what I was looking for! Did not over use any product which made my hair feel clean and fresh!

I've been going to Lo for a couple of years now and have consistently received the best haircuts of my life! I have incredibly thick, wavy hair and she always gives me a cut that looks great out of the salon and grows out beautifully.

Ashley Franco is THE BEST! I've been seeing Ashley for over the past two years. She has a keen eye for current trends, which I don't, that she executes with precision and mastery. But what really keeps me sticking around is her open, friendly, humble personality that feels like a breath of fresh air in this world.

Would give zero stars if I could. I drove over an hour through rush hr traffic from the suburbs as this place was highly recommended. I ended up 5 min beyond my appt grace window (15 min) and they turned me away... And that was with a call in advance giving a notice I was stuck in traffic... Haircuts might be good but the customer service not so much.... They asked me to reschedule... I'd love to just with another salon.

I’ve gone here in the past, and was very happy with the results! However, my most recent experience wasn’t as comparable. I had gone in asking for a balayage with a lighter highlight in the front. As for the haircut, I had asked for longer layers in the back and chin-length curtain bangs. My hairstylist was extremely nice and seemed to understand and grasp the idea of what I wanted. She walked me through everything we did which was really appreciated. We agreed on taking off 2 inches of my hair as my ends were dry, yet I wanted to still keep my length. I was sad to see about 5 inches come off

Emily is such an excellent stylist! She is so easy to talk to and makes the process fly by! She’s also willing to take risks and do fun colors, as you can see! I love coming in for service with Emily!
