hair coating

Drying can be done at 30℃.
Meanwhile, drying at 40℃ can makes better coating effect and longer time of effect lasting.
If you can, please keep hair dried at higher temperature than 40℃, 50℃, or 80℃ (in case of human hair) for better coating effect and longer time of effect lasting.

WHILE HAIR (HUMAN HAIR, SYNTHETIC FIBER) IS BEING DRIED IN AIR OR BY HEAT AFTER TREATED WITH SOLUTION (MIXURE)
OF JK-HAIRCOAT & WATER , PLEASE DO NOT HAND-RUB (FINGER, MASSAGE) THE HAIR.
OTHERWISE, THE FILM OF HAIRCOAT CAN NOT BE FORMED FIRMLY & EVENLY ON THE SURFACE OF HAIR.

FOR DRYING HUMAN HAIR(-PIECES) OR SYNTHETIC FIBER (-PIECES), YOU CAN USE "NATURAL DRYING (AIR-DRYING)" BY KEEPING HAIR (HAIR EXTENSIONS, WIGS, WEFTS) HANGING ON A STRING OR A CLOTHSLINE, OR PLACED ON A MEtal MESH, A (ALUMINUM PANEL(TRAY) WITH MANY SMALL HOLES.

Hole size ?
Distace between holes ?

- No use of a spin dryer or a drying machine (oven)

Reviews of an individua user (blonde wigs, USA):" I did the dip method with three wig units(light blonde), in warm water mixture. I let them air dry. All three showed an improvement in texture after drying. I curled one with a curling iron and hot comb and that one showed a further improvement in texture and shine. JAN 31, 2024"

(cold) Air Drying

Reviews of a hair extension manufacturer in Europe: "Hello John, I can tell you that I am very very satisfied, I am very satisfied with your JK HairCoat, we do not dry it in the stove, I wash it hot and even dry it cold now it is especially now that it is cold here in Europe and I dry it cold and when I iron it like that good hair something fantastic I am very grateful to you

A Hair Blow Dryer can be used for drying.
Meanwhile, for maximum coating effect, a hair blow dryer is not recommendable because wind makes hair strands sway, shake, flutter, the coating layer can not be formed(solidified) firmly, strongly, densificately on the cuticle or surface of shaking hair strand.

An electric Dish Dryer (temperature range: 55 ~ 60℃) can be used as a drying oven.

A clasic baking oven can be used.

Reviews of an individual user (blonde toppers, Europe) of JK haircoat JK7825:
"John, I already found the answer to my questions when i searshed more in deeply on your website. So the only think i want to ask is, if i can use a baking oven for drying the hair and apply heat?
Clasic oven for baking. I would set the temperature to 65 degrees and let the door of the oven half open"
@@ John Korea - "half open is too much, just 1 or 2 cm open".

"Only squeezed it with hands. I was afraid that if i use a towel to dry it i might take of a lot of the coating. Maybe it took less than six hours to dry. Maybe it was four hours. I did not watch the time. I was only checking the hair if its dry"

"I already tried your hair coat on my toppers. (Drying it in the oven workes perfectly). Oh my god !!!! I can't believe the amazing result ??!!!! The hair on my old topers is completely restored !!!!! Amazing!! Im so happy

!!"

Steps for oven-drying

Have hair treated with JK-HairCoat solution spin-dried for about 6 minutes with a washing machine (CW466-H) to remove 80% of water (or solution) from the hair - wet-feeling but nothing dropping,
Spin-drying can remove build ups (pileup, residue) of JK-HairCoat remaining between the hair strands.

place the hair on a tray with holes (5 mm in diameter) indistance of 5 mm far from each other,

set the temperature to 75℃ ~ 80℃ and set the time to 2 hours or more depending on the amount of hair.

have the dried hair cooled down in the oven for a few hours or more (overnight).
Please do not touch (pull, stretch, rub, hackle) the hair when the hair is (feels) warm after drying using an oven.

If you wash the hair which is still wet (not dried) after JK-HairCoat treatment, the effect will be a little bit less and may not last long time.

@@/ If you have the haircoat-treated hair not spin-dried before putting into an oven, you can have better or worse coating effect because more haircoat will remain on the cuticle (surface) of the hair.

	In case the hair is not spin-dried, the drying time should be over 4 hours in case of a few kgs of hair, or more than 7 hours in case dozens of hair is to be dried in an oven (drying machine).
	You can use a room in your house (for example) as a drying room. and prepare(use) something just like A MOSQUITO NET in metal and a stove (heater). In that case, you should have the window a little bit open, 1 cm (?) so that moisture or water on the hair can vaporize away through the opening. Otherwise, the hair will be not dried, or will be steamed.

	In case you do not have any spin-dryer or a washing machine used in your house, just take hair from HairCoat-solution (mixture) squeezing out the solution from the hair, and place the hair on a mosquito net or on a metal tray with holes or hang the hair clothesline to dry in the shade in well ventilated place.
	@@: I would suggest you do spin drying using a spin dryer (CW466-H) in case you treat 1 bundle of hair (100 gr / dozens or hundreds of hair strands) tied with a rubber and, please do SPIN DRYING 2 times , having(keeping) the location of the rubber band changed (moved) each time. Otherwise, the HairCoat solution (water & HairCoat) of the hair strands under the rubber band will not be removed enough, and there can be residue (HairCoat deposit, scum) remaining between hairs, specially around the place tied by a rubber band. Of course, there can be the case you can have better effect or result without spin drying. Just have tests 2 ways, with and without spin drying.

WHEN YOU USE AN OVEN FOR DRYING WITH HEAT, THERE MUST BE AN OPENING WHICH VAPOR OR MOISTURE FROM HAIR CAN VAPORIZE AWAY THROUGH WHILE BEING DRIED WITH HEAT OR HOT AIR IN THE CHAMBER ( IN THE OVEN). OTHERWISE, HAIR WILL BE STEAMED OR BOILED, NOT DRIED.
[[ WARNING IN HEAT- DRYING OF SYNTHETIC FIBER ]] MEANWHILE, WHEN YOU DRY SYNTHETIC FIBER-PIECES AFTER APPLYING THE HAIRCOAT CW7892-FR-GN(General fiber) or JK7899-FR-HR(Heat Resistant fiber), PLEASE USE HEAT ( if you can use an oven, or heat for drying) AT AROUND 40 ~ 50℃. SOME OF SYNTHETIC FIBERS CAN BE CHANGED IN QUALITY AT 70, 80, OR 90℃.YOU SHOULD HAVE TESTS ON THE FIBER OF YOUR WIGS OR HAIR EXTENSIONS BEFORE YOU USE HIGH TEMPERATURE OF HEAT FOR DRYING. OF COURSE, IF YOU CAN BE SURE THE FIBER OF YOUR WIGS OR HAIR EXTENSIONS ARE MADE OF HEAT RESISTANT FIBER, YOU CAN USE 80℃ OF HOT AIR OR HEAT.
If you would treat hair by dozens of kgs and dry the hir, please email us so that we can guide you with the drynbg method for large quantity-drying with a big size of a drying machine.
