Here are some ways to wash your hair extensions so as to make it last for a long time.

Gently brush the extensions before you wash them to make sure there are no tangles.

Wash your extensions with a small amount of gentle shampoo, but only after a few days' wear. (NOT baby shampoo, which isn't actually gentle at all.) Make sure to rinse them well so you don't leave a residue of shampoo on the extensions.

Use a small amount of good conditioner, and again, make sure to rinse well afterwards.

Comb them through GENTLY with a wide-tooth comb. (Hair is weaker and more prone to breaking when it's wet).

Brush and comb your clip in human hair extensions carefully - no tugging! Use your fingers and your patience if you come across a small knot.

Never use a rubber band to secure the braid or pony tail. Easy to put on, but difficult to remove, rubber bands will break hair, whether it's yours or on an extension.

Follow the above ways, your hair extensions can last for a long time.
