Before washing your hair extensions, you must ensure that there are no knots and tangles present in the hair simply by using a soft brush.
Do not tug on the hair as you can rip out the hair extensions.
Then, gradually wet your hair, brush it again and then apply mild shampoo.
You should wash in a downward motion to avoid creating additional knots and tangles. Just pat dry the hair instead of rubbing it and then brush only when it is completely dry.
