Clip on hair extension questions?

I have I&K human hair clip in extensions. You can sleep with them in but they might be uncomfortable or get pulled out and you might have to put them back in the morning. The point of clip ins is that you can take them in and out very quickly and easily. You can swim with them but wash them well after. I would take them out for swimming if they are lighter than dark brown because they might have been bleached to the colour required. Take extensions out to wash your hair because the hair and yours will get tangled in the clip and if you blow dry your hair the clip could get hot. It depends how often you wear them as to how often you wash them. If you wear them everyday then once or twice a week or if you curl them you might want to wash the curl out. I wash mine with my normal shampoo and conditioner under the tap, hot, warm, or cold it doesn't make much difference. Straighten them separately and then put them in because if not really secure the straighteners will pull them out. Curl them already in your hair so they match the curl and the curling iron doesn't pull. Very easy to put in, mine take a few seconds for each one.
