How long does an eyelash perm last?

How many weeks does it usually last if I get it done at a salon?

My daughter did it for me herself at home.

I did it on the 5th.

It's been 12 days and the curls are still alive.

It's fascinating hahaha

It took about 30 minutes, so if the duration is this long...

I think it's something I can do myself.

It's still going up strong ^^
