How do you remove hair extension that are glued into your hair?

You can Shampoo it out, while shampooing your hair used warm to hot water as the shampoo and water mixes, use that to pry the glue up as it should get softer with water and shampoo in your hair.

Before shampooing add some oil or grease to the area where the glue is, that will make it easier to come up out of your scalp.

You may have to shampoo several times and gently lift up where the glue is.

In the beauty Supplies today they also have some bond glue remover.

Also they have some items that can be applied on the hair so when you glue some weave in the glue won't get directly on your hair and scalp which makes it much easier to remove.
