Washing your hair at least once a week is recommended.Some people like to wash their hair every other week, which is fine just try not to use too much product in between washes.
To help maintain hair for as long as possible deep conditioning every 2-3 weeks is recommended especially for curly hair.
This also makes it easier to manage the hair and creates fewer tangles.
The benefit of using 100% human hair is that is very versatile, you can style it like your natural hair. You can brush, comb, blow dry, curl with curling iron, straighten with a flat iron and style it any way you want.
Please be mindful that heat from blow dryers, flat irons, curling iron etc. cause damage if used excessively.
Just like your natural hair this hair also will break off and become damaged if you abuse it with heat and aggressive styling agents.
Detangle your hair with a brush then braid it, wrap it or tie it up in a bun before going to sleep. This will avoid any unwanted tangles.
Do not sleep with your hair wet, as this will create tangles also.
I recommend satin pillowcases or bonnets to sleep with.
