Hair Tinsel;
Can I wash and style my hair?
Sure! Just don't shampoo too vigorously, that may shake them loose and tend to make them fall out faster. And you can flat iron, curl, blow dry, just as you would your own hair.
How are they put into my hair?
Hair tinsels are tied into the hair and kept in with a knot.
Can I remove them?
It's best to leave them in until they are ready to come out on they're own, other wise you could risk ripping out the hairs its tied to, but if you need them out, you could just undo the knot, no guarantee you won't loose hairs.
Can I color my hair?
Not unless you want to damage them.
