Finding a hair stylist you actually trust is a lot like dating. You go through a few "meh" experiences, maybe a catastrophic heartbreak involving bangs, and eventually, you just want someone who gets you. If you live in the San Gabriel Valley or Inland Empire, the name Kim Sun Young Beauty Salon Diamond Bar usually comes up the second you mention wanting a digital perm or that specific, glass-smooth "Magic Straight" look.
It isn't just another strip mall salon.
Actually, the history here is kind of wild. The brand started way back in 1956 in Myeong-dong, Seoul. Back then, they were literally using heated coal briquettes to warm up curling irons. Fast forward to today, and that same heritage is tucked into a clean, modern space at 20627 Golden Springs Drive.
The Magic Straight Obsession at Kim Sun Young Beauty Salon Diamond Bar
Let’s be real: most people head to Kim Sun Young Beauty Salon Diamond Bar for one thing—the permanent straightening. They basically pioneered the "panel straight" method. If you’ve ever struggled with frizz that laughs at a flat iron, you know the struggle.
The technicians here don’t just slap chemicals on your head. They look at your hair health first. It's a process. You’re going to be sitting in that chair for a while—anywhere from three to five hours depending on how much hair you’re rocking. But the result? It’s that effortless, "I woke up like this" silkiness that lasts for months.

Why the Digital Perm is different here
If you want curls but don't want to look like a 1980s prom photo, the Digital Perm is the go-to. Unlike a cold perm, this uses temperature-controlled rods connected to a machine that looks like it belongs in a sci-fi movie.
- The Volume: It creates big, bouncy waves that look better as they dry.
- The Maintenance: Honestly, you just twirl it with your finger while blow-drying.
- The Longevity: It survives the California humidity better than almost any other treatment.
What it’s actually like inside
The vibe is sophisticated but not snobby. You walk in and it’s sleek—lots of clean lines and soft lighting. It’s the kind of place where you can actually relax. Stylists like Mijeong have built a massive following because they pay attention to the tiny details that other places skip.
Some people think the prices are a bit steep. A haircut might start around $65 for women, and those specialty perms can easily clear $300 or $400. But when you’re dealing with permanent chemical changes to your hair, "cheap" is usually a recipe for disaster. You're paying for the fact that they won't fry your ends.
Beyond the Hair: Lashes and Makeup
It’s called a beauty salon for a reason, not just a barbershop. They do a lot of "Yumilash" lifts and even semi-permanent makeup.

If you have a wedding or a big gala coming up, they offer full bridal packages. We’re talking the works—hair and makeup that stays put even if you’re sweating under reception lights. Their microblading services are also a huge draw, though you usually need to book those way in advance because the specialist stays busy.
The Logistics: Hours and Appointments
Located right off the 60 and 57 interchange, it's pretty easy to get to, but parking in that Golden Springs plaza can be a nightmare during lunch hours.
- Monday through Saturday: They usually open at 10:00 AM and wrap up by 6:00 PM.
- Sunday: They have shorter hours, typically 12:00 PM to 5:00 PM.
- Walk-ins: They technically accept them, but don't count on it. This place stays booked.
Is it worth the drive?
If you’re looking for a $20 quick trim, this isn't your spot. But if you want a stylist who understands Asian hair textures or someone who can execute a complex Korean trend you saw on Instagram, Kim Sun Young Beauty Salon Diamond Bar is hard to beat.
The staff is friendly, the environment is safe, and they’ve been in the game longer than most of their competitors have been alive. There's a reason people drive from places like Irvine or even further just to see their specific stylist here.

Real Talk on Results
No salon is perfect. Some reviews mention that the language barrier can be a thing sometimes, or that the upcharges for "long hair" can surprise you at the register. Always, always have a consultation first. Ask for the "all-in" price before they start mixing the bowls.
Most of the time, you get exactly what you pay for: high-end technique and hair that feels healthier leaving than it did coming in.
If you're ready to change your look, your best move is to call (909) 594-9498. Ask for a consultation regarding their thermal straightening or digital perms. If you have a specific "Inspo" photo, bring it, but be open to the stylist’s advice on what will actually work with your hair’s current condition.
