How often to do you re-touch your pink highlights?

I did mine last night, and they're really cute today, like a raspberry pink. But I just wanted to know how often I can expect to have to re-touch them. I'm dying the pink on bleached hair, if that matters.How often to do you re-touch your pink highlights?
im in beauty school and from what ive learned and saw pink fades really fast into like a carmel blonde color so i would suggest every 3 to 4 weeks but be careful because if your hair is colored to much it can damage it really badHow often to do you re-touch your pink highlights?
Most people have to re-touch there highlights or hair color once a month. like I just got black underneath my hair and I just did it last night to so I will have to expect to re-touch it next month. That will be February. But You can tell when you need to get it touched up!
I suggest re-touching them everytime they start to look faded. Which is about like every few weeks or so, just re-touch them when you think you should.

Well do it when it starts to look faded, about every 3weeks. I had brown hair with the underneath shadow part pink before
retouch them every month, as long as you want to keep them
