    Patrick is the man. I keep coming back to him because he knows how I like my hair done. So if you need a haircut he's the man.

    Patrick sucks, over charges and doesn't even style the hair basically just cuts hair off.

Came in with some inspo pics (Hudson Williams, 90s Keanu, Jackie Chan shag vibes). Rich was very patient and knowledgeable, he indulged my questions about everything. We made a game plan on how to trim and layer my hair and what I was going for. I LOVE THE RESULTS. It's literally the kind of style I want to effortlessly have but can rarely achieve bc mi hair soy super Asian (kapow!). I'm so glad I did it (finally) and looking forward to enjoying it. Highly recommend!

    This review is long overdue. Almost 8 years in fact. JJ has been taking care of me for as long as I…read morecan remember. It all started with a cold call to the shop / getting an appointment with JJ back in 2018, in which turned into entrusting him with cutting my hair since. This is THE guy, let me tell you. JJ is the most laid-back, coolest, most sincere barber I have ever had the pleasure of dealing with. I truly look forward to every appointment I have to get freshened up / vent / chat with him. My dude has been with me through thick and thin, life and hair literally. From weekly buzz-cuts to now bi-weekly scissor-cuts, he has always gone above and beyond to make my experience the best it can be. If you are looking for a barber in San Jose, please, look no further and book an appointment with JJ ASAP! You will not be disappointed with the exceptional service you receive. Thank you for everything brother!!!

    I waited about a week before writing this review so I could cool off and see if I'd feel…read moredifferently about the haircut. Unfortunately, I'm still very frustrated with the result. I have medium-long hair and specifically requested a scissor cut. I explained that I only wanted my current style lightly trimmed and layered to remove some bulk and make it easier to style. During the appointment, the barber had his child with him and seemed fairly distracted, taking multiple breaks to tend to them. I tried to be understanding, but it definitely affected the focus of the cut. At one point I asked for just a small amount taken off the back since it was slightly longer near my neck. Unfortunately, too much was cut, and I was told more would need to come off the top to make it look uniform. More was then taken off the sides as well, again much more than expected. The end result is very uneven and honestly looks like a botched mullet. I normally never leave negative reviews, but this experience has been really frustrating. I've been wearing a hat because no amount of styling has helped, and now I'm basically waiting for it to grow back. It's unfortunate because I came in hoping to simply clean up my existing style.

Even better, he is patient and takes the time to explain different methods and all of the fun insights behind different hair looks you can achieve. Also he makes recommendations to point you in the right direction, including other stylists at the salon that specialize in certain things. Highly recommend!

    I had an appointment here the other day for a perm with one of barbers (Kevin/K-Luk) here who had a…read morerespectful portfolio on his social media. I showed him my reference pictures (loose flowy perm for middle part) and style (wolfcut) that I was hoping to achieve. He said we could achieve something similar to the pictures that I showed. I mentioned that I had processed hair on the back of my head and questioned how to proceed from that. He told me initially the perm wouldn't look right if he didn't my entire head so I agreed to proceed given the possibility that the perm may fry the back of my head. He also mentioned to me that I needed a haircut to which I asked him if I could add it on as I assumed I would be able like most of the other salons/barbers that I have been to before. He told me he couldn't as he was booked. He begins to perm my hair and talks to another colleague and mentions he going to avoid my processed hair. We finish the perm and he washes the solution out of my hair and shows me my hair. It's significantly curlier and different than what I expected. But didn't look too bad because it was still wet. I didn't want to say anything because I hoped once my hair dried, the perm would look less curly as it has in the past and I didn't want to say anything since I waited over a month to book this appointment. I had paid previously and tipped 20% during the booking of it. As I drive home, I noticed my hair looking more and more poofy on the sides--almost like those kids who grow out their hair/surfer hair. Once I get home, my hair is a lot more dry now and I noticed that the sides were all sticking out horizontally like a fish hook. I showed my girlfriend who told me that this was the worst thing she's ever seen. The sides were totally messed up and the back looked horrible. I ended up going to another salon that evening because I was in shock of how bad the perm turned out. I asked the stylist there if there was any way to layer and fix it, to which they informed they couldn't as the perm rods were not placed appropriately for a middle part and said the only way to fix it was it cut off. Given how bad the perm turned out, I opted to cut it off. I mentioned all of this to my barber the next day on his social and he didn't even seem to care. He told me I should've had my hair layered before the perm and that my hair looked weird because he didn't perm the processed hair. As a customer who showed him the reference picture, if he didn't believe he could achieve the results without layering my hair/didn't believe he could achieve it then why go through with at all. I would've skipped the perm or only done a haircut if that's what he believed was achievable from the reference picture. Even from the picture of the back I sent him, he could tell that the perm looked bad but let me walk out of the shop without even trying to fix it. I already paid/tipped beforehand so there's no incentive to fix a bad service because you're just an invoice at this point. The customer service at this places isn't good. If you gave someone a really bad perm/service and don't care about your mistake or don't care to offer ways to assist your client, it just shows you that you're just a dollar sign to them.
