I think that's so cute! If it was absolutely pin straight it wouldn't look natural at all.


Don't wear extensions...its fake hair. I don't know how you can do that...
your hair looks pretty like that. but while your starighteening your hair hold the straightner at wherever you need it to be straighter for about 5-7 seconds. it works.... for me at least. hope this helps.
