When washed my hair extensions, can i dry it with a hair dryer or just naturally?

I would seriously ask you that all types of extensions need different types of care and require specialist shampoos/conditioners. I'm a qualified stylist with many years experience and have seen some major extension disasters when they have not been properly cared for. e.g. a knot the size of a tennis ball that took over 4 hours to remove and untangle. Be careful and get professional advice from the person who fitted the extensions, they can be beautiful providing they get the care they need.

If you have already washed your hair, comb through the hair thoroughly till they dry, using a hot dryer as it may singe or tangle them.
