Can I safely lighten my hair at home with developer?

Question

Hi, I have fairly long naturally black hair. For years now I have been getting it lightened professionally by my hairdresser. It is not unusual for me to pay $100-$120 to get my hair colored. Well, I had to switch hair stylists bc my stylist was booked and I needed my hair done. The new colorist didn't use anything but a 30 developer on my hair. It brought the color down to match my outgrowth perfectly without color. So...I saw some 30 developer in the beauty store the other day. What do you think? How long should I leave it in? I believe she left it in for only 10 minutes.

Do what she did for the best results
