Dark to blonde

Hello everyone 🙂

I have waist-length dark brown hair (not quite virgin, I have some barely visible highlights from last year) and I'm absolutely bored with it. I never let my hair down anyway so the length doesn't do much for me as I always keep all of my hair in a ponytail.

I have an appointment at my local hairdresser's on Friday since I have to get about 4 inches cut off anyway, and now I've been thinking about finally fulfilling my life-long dream of going blonde *lovestars*

I'm really afraid my hair is going to snap off though. I assume I'll have to go there 2 or 3 times anyway and my hairdresser is very professional and has tons of experience... But it would be such a shame since my hair is so long and thick and healthy ???

Has anyone of you bleached long dark hair to blonde? Or had it done at a salon? Did you get chewing gum hair? My only experience with bleach is virtually invisible balayage (had it done 3 times, hair feels super healthy) with 6% bleach at a salon. And, well, one box dye experiment 😀 I bleached my ends twice in a row to dip dye them green. They were light brown and felt like straw but they didn't fall off or anything so that's good news, right?

Awful picture attatched, edited because weird facial expression. But that's my hair right now. Darker in natural light and maybe 2 inches longer.
