Does anyone know how real hair extentions are applied and also taken out.?

There are 2 ways.

The 1st is weave-on:the hair is woven into tiny ridges and the extensions are sewed on.Removal is by taking out the stitches.

The 2nd is stick-on:the extensions are applied with an oil-soluble glue. Removal is by applying a lot of oil to the area of attachment and gentle tugging.

Go to a salon that has a good stylist, (preferably black) and they know how to work it out, other methods of attaching them are by glueing but that is really gross, especially the removal part.
