If you've got a doll who needs her hair replaced or even just one or two plugs, ad you are unsure how to re-root the hair yourself, check out my Squidoo Lens Tutorial.
In it I let you know about the different types of hair that are available and show explain how to attach it to your doll's head and includes links to websites where I buy my favourite types of hair to use.
One day, I may get around to copying the entire thing here, (if I can remember where I put all the images I used that is!) but for now, you can just click on the link below the picture, and it will take you straight to the Lens page.
Above all, have fun!
