Your hair hasn't been bleached light enough to be able to turn the pale peach colour in your inspo pic.
Your hair would need to be a level 10 blonde - the colour of a peeled banana, you might possibly get away with a level 9, if it gets toned to a silver blond and then the peach toner is then put on top of it.
Red hair can be hard to lift (meaning lighten with bleach) as red tones are what keeps it looking brassy.
I am.assuming your hairdresser bleached your hair and it turned a bright yellow/orange colour and then she tried to tone it with a blue/purple toner.
Using the colour wheel orange and blue make greeny/brown which is where your hair is now.
She is correct in saying come back in a month.
Your hair would be very compromised if she were to bleach it again before then (break off or fall out)
She probably covered the bright orange yellow hair last appointment so your hair looked better than walking about with really brassy hair.
You need another round of bleach to get light enough to be able to tone to the pale apricot peach colour you want to be. The bleach will get rid of the khaki colour and shoukd take you to a level 9/10 and enable you to have the hair of your dreams.
In the meantime hide it in a bun, or do heatless curls....curls hide a weird colour better than straight hair and wait for your next appointment.
