Uijeongbu hair salon: straight-hair partial down perm, Trinity Hair

In short

Trinity Hair Geumo is an appointment-only hair salon next to Woori Bank in Geumo-dong, Uijeongbu. The writer's husband has straight hair that grows out like a mushroom cut, so at Trinity Hair Geumo he got a short cut, a partial down perm on the sides and top, and a protein booster clinic for an extra 20,000 won, all in about 1 hour. He keeps going back for the clean hairline every time, making Trinity Hair Geumo his regular salon for men's cuts and down perms.

Trinity Hair Geumo, the Uijeongbu men's hair salon my husband loves

Trinity Hair Geumo (트리니티헤어 금오점) is a hair salon in Geumo-dong, Uijeongbu that I go to regularly. I get my own hair done there too, but my husband always gets his cut + down perm there, and it comes out so neat and just how he likes it every time that it's now his favorite salon :~)

Let me show you the before & after first. I've recorded the whole process below in detail, so if you're looking for men's hair in Uijeongbu, take a look :~)

Inside and the waiting area

The interior is really clean, and the waiting area is roomy, so anyone who comes along won't get bored waiting! There are lots of chairs too, and since it runs by appointment, treatments don't overlap, which I like even more.

Why a down perm is a must for straight men's hair

My husband has straight hair, so if he skips a cut for just about 3 weeks, it gets super shaggy and messy. The longer it grows, the rounder it gets, like a mushroom cut, so a down perm with the cut is a must!

A partial down perm instead of a full one

At Trinity Hair Geumo, my husband gets a partial down perm that only presses down the sides and top a little. A full down perm makes his face look too soft and round. They do it to suit his face shape and image every time, which I really like!

Add Ayunchae oil if you dye or down perm often

Trinity Hair Geumo has a treatment where "Ayunchae oil" (아윤채 오일) is mixed into the dye and down perm solution to minimize irritation to the hair and scalp and make the result last longer. Women don't get treatments that often, but men do it every 3–4 weeks, so if anything the scalp gets more irritated and damaged.

If you down perm or dye often like my husband, care about hair health, or have a scalp sensitive to irritation, I'd recommend adding this to your treatment. There was definitely almost zero irritation afterward :)

The process: from the cut to the partial down perm

After the consultation, the cut comes first :~)

Short men's cut in progress after the consultation

My husband prefers short hair, so they cut it as short as possible. The hair gets cut and then pressed down with the down perm, so it has to be cut with that in mind!!! They trimmed his eyebrows too.

Cut done! It looks fine from the side, but from behind the straight hair makes the sides grow outward and look weird?! That's why we always press it down with a down perm.

Before applying the down perm solution, they also put on a cream that protects the skin.

Then the down perm solution is applied evenly. I tried a down perm at home once, and it was sooo much harder than I expected. Since then I only let the salon do it..

Protein booster clinic: I added it for ₩20,000

Trinity Hair Geumo's "protein booster" treatment was on sale, so for an extra ₩20,000 I added a clinic treatment for the first time in a while. You go to the shampoo area, they rinse the down perm solution out cleanly, then spread the clinic product evenly over the scalp and finish with steam.

Looking closely, there are little granules in it!

We can't do it with every treatment, but doing it once in a while seems better for scalp and hair health, and after dyeing it feels like it would help clear out leftover dye residue too!

After the steam you get a light, refreshing scalp massage and a rinse, and that's the end of the whole treatment! From cut to down perm to clinic, it took about 1 hour!~

Neat on the sides, front and back! Trinity Hair Geumo also sharpens up the hairline, so I'm always happy with the cut and treatment :-) You can book through Naver booking.
