Step 3: Boil the Kettle
Now, get the hot water out. The water should be close to boiling, to start with. (If, however, you notice that the hair fibre starts to go into a zik zak sort of form, cool the water down a little. In some rare cases this may occur, but it's reversible with cooler water.) First, pour some hot water on the dolls hair and make sure it's wetted throughout. Don't burn yourself! (Rubber gloves might come handy, or you just be careful.) Comb the hair with the steel comb first, without laying the doll on the plate yet, unless you so prefer, adding hair conditioner here might help you out. When the metal comb goes through, try the flea comb or the eye lash comb, like in the picture here, on a plate.
Now, if the doll has had a ponytail for the last 5 years, she probably has that somewhat hilarious tube hair -look, and you want to sort that out. You will want the neck hair back to where it should be, hanging down instead of pointing horizontally behind her. This is where the plate comes in handy. First, comb the hair on the plate like it's shown with the dark haired doll. Then, little by little start laying the doll onto her hair while combing, like shown with the blond girl. There are other ways of achieving the same result, this is just one of them, so feel free to experiment.
And last, hold the doll up and put her in sitting position while pouring the last of the boiled water on her head. (Holding on her legs will save you from burning your fingers.) Then, comb the hair in the position you want it to stay, towel dry and let her dry up over night. (Don't use the blow dryer even if you're impatient, that will easily ruin the hair!)
Put some clothes on the poor girl.
Once the hair is dry, it may be static. If this is the case, you can tame it down with some light moisturiser. (Spray thing is great to put straight on, but normal will do; apply to hands first and then stroke the hair before the moisturiser is fully absorbed into your hands.)
