Diesel Barbershop Highway K, O'Fallon MO

Got us in same day. Had to ask for the hair line to be evened up after the cut was complete. Would give them another try. But ask for a different barber.

First experience was awful, second experience was worse. Daniel cut me when I got my beard shaved. Not worth the time

Michelle rubi was awesome my first time getting a cut here and everything about the atmosphere / customer service / services will have me coming back

Michelle is awesome.always goes above and beyond.the treatment is amazing.never had a bad cut from her.thank you Michelle.

I rarely write reviews. Geno cut my hair today and it is hands down the best haircut I have ever had!

I had my first visit this morning. I had a busy day ahead of me so I got there before the doors opened. I was very impressed by this place. I was greeted kindly and offered a beverage before my haircut. (Beer included!) The owner was present and was very kind. I had the pleasure of being cut by Kayla. She keeps a good conversation going and is naturally a people person. She sat me in one chair for the cut, shampoo, and style. Kayla recommended a great pomade to use for the day and I purchased some to take home. On top of all the great things they were able to notch me for an opening on the calendar that worked best for my schedule. I am very happy with this experience. Thank you for coming to O'fallon, MO!

I'll be back!

Perfect barbershop. Staff is very friendly. My son and I had a great time. Arcade games and drinks were free too

They knew what hairstyle worked best for us which made it a very easy experience

My boyfriend has been here a few times and liked it but today he went and had a new girl in training. The picture says it all! I can’t believe they let him walk out of here like this. In training or not I don’t know how you mess a line up like this. Wasn’t going to post this until we called another local barber shop and told them what happened and they said Let me guess it was at Diesels. Apparently they have had to fix 5 cuts from here over the past 2 weeks.

The lady who cut my hair did even better than what I told her, I usually would get my haircut at great clips but not anymore, this is my new place.

Michelle was a fanstatic, perfect technique with a side of happiness. She brings a calmness to a chaotic world. Allowing me personally to reset for month. She is exactly what this world needs and im happy I could be apart of the experience.

Haircut took nearly an hour cutting 1 hair at a time, and still has an odd look on the back somehow. Told me afterwards “did they let you know it was $10 extra for the skin fade? ” They didn’t, and I didn’t ask for a skin fade, they just gave me one. Also didn’t get the shoulder massage. $50 is outrageous for the service

This has been the greatest Barber service that I’ve ever had. Lorna with the cut and Rania with the straight razor shave! Can’t ask for better service.

I have been looking for a “trendy“ place to get a haircut and wanted a disconnected undercut. These guys were able to oblige and they were very easy to work with. They offered me a drink right when I walked in the door and they made me feel like a regular customer even though it was my first time being there.

Eric was great! Did a great job on a beard trim and very personable. Will definitely be back

This place is spectacular. Michelle did great today and I've never had a bad haircut at this place. They pay attention to detail and take their time because each stylist cares about their craft. I couldn't recommend more.

I had a pretty bad experience with another local barber shop so I tried Diesel out even though it has a considerably higher price tag. I don't regret anything, and I will continue to see Michelle every few weeks!

Michelle always does an amazing job with my boyfriends hair! She's the best and tolerates our nonsense.

Great place to get a haircut. Rania listens to what you want and the haircut comes out perfect.

Eric and Gino were great! Gave me one of the best customer services I’ve had during a cut and also a great haircut!

Big thanks to Michelle for fixing my fiances hair after he had received a bad hair cut! You did a fantastic job and we are incredibly happy with the results!
