Skip ahead a couple years after high school. My twin sister finished cosmetology school and became a successful hair stylist. So..... my hair has been short (and blonde!) ever since! I really like it short but it is sooooo much work to style. I have to style it immediately after the shower while it's still soaking wet, apply mousse and volumizing spray, blow dry, round brush, gel at the roots, flat iron, and tons of hairspray. And after all that work, it's nothing special!!!
So last week I decided I would splurge and purchase clip-in hair extensions.
I purchased them from Sally's Beauty Supply for around $90. I can't find the exact ones online, but these are close to the same ones. They are real human hair, so they can be flat ironed, curled, washed, etc. My plan was mostly to use them in ponytails since I haven't been able to wear my hair back in 20 years! But I'm on vacation this week, so I have been wearing them down. I'm considering having my sister cut them a couple inches.
I used the clasp-less curling iron to curl them in this pic:
