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~~~

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.

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.

Before the cut

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...

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.
