Now that the weather is getting nicer, every time I looked in the mirror my dry, frazzled hair bugged me T_T My roots had grown out a lot and the overall tone had gone patchy, so this weekend I finally made up my mind and went for a makeover at Demon Hair Sinchon Branch!
I was so happy with everything from the consultation to the details of the cut that I'd highly recommend it to anyone hunting for the best layered cut in Sinchon~~~

Inside Demon Hair Sinchon Branch
The salon is on the 2nd floor, so it's flooded with natural light and feels really bright~


The space is pleasant, so even with lots of customers it never felt crowded and I could relax through the treatment~~ The interior is stylish too, so I felt properly pampered the whole time. ✨
The shampoo chair is really comfortable, and they even draped a blanket over me during the shampoo. Such a thoughtful touch 🙌
How does the consultation for a layered cut and all-over dye work?
At Demon Hair Sinchon Branch, I talked with the head stylist first, then had the layered cut and all-over dye done in the same visit. The stylist looked carefully at my style and face shape, and was the one to suggest blending ash into the dye to cover my gray hair.


It was so hot out that they thoughtfully set out drinks and snacks for me~~ Today's treatment started after a consultation with the stylist! They're super kind.

My hair felt heavy, so I did the layered cut and the all-over dye together~ The stylist really took a careful look at my style and face shape!


They were the first to suggest blending ash into the dye to cover the white hairs, which was so reassuring... They read exactly what I needed and nailed the consultation, so it was super comfortable!

The layered cut and all-over dye, step by step
They lightened the ends of my overgrown C-curl with a layered cut, then did an all-over dye in a matte tone with no reddish cast. They also took care of the details: aroma oil before the cut, ear covers during the dye, and a Rapunzel cream finish.

I kept growing my hair to keep a C-curl at the ends, but it got way too long ;;
I decided to cut the heavy, stuffy-looking ends into light layers. I asked for layers that look refined without being too wispy~
Aroma oil before the cut
Before the cut, they apply aroma oil. The options were, in order, stress / blood circulation / puffiness care, so I picked stress!! The aroma really calmed me down. Work stress has been pretty heavy lately, but for this moment: inner peace...

Matte-tone all-over dye with ash blended in for gray
After the careful layered cut, they firmly put covers over my ears so the dye wouldn't get on them,

and while applying the dye I could feel how carefully they handled my scalp, with no stinging at all! I hate the reddish tint that shows up as dye fades, so I chose a matte, classy tone~~

The shampoo was so refreshing that my mood shot up!! They also applied Rapunzel cream, which is used in repair care, as a free service, thank you so much T_T
Before and after: how did the layered cut and ash dye turn out?
With the all-over dye at Demon Hair Sinchon Branch, my patchy tone evened out, and the layered cut gained volume with just a light blow-dry. My hair feels lighter, so washing and drying are much easier.


When I finally saw the finished look, it was exactly what I'd wanted!

With the patchy spots evened out, my overall look seems much neater~~

The layers are a work of art!!! Just a light blow-dry and the volume came back, and my face even looks smaller! 😆

With lighter hair, washing and drying are so much easier!! When I went to work the next day, everyone said the dye and the cut both looked great, which made me so proud!!
