Bleaching my hair into two sessions? Bad idea or safe?

Hello

Before I continue, please do not tell me to go to a professional because i just can’t.
This is my first time bleaching my hair by myself and to be safe I wanted to bleach the bottom half of my hair (with a timer of course) and then finish bleaching the top a few days later (with the same timer I recorded previously) Is this a bad idea? I have long and thick hair so I’m just nervous about doing it all in one shot

Most likely a very bad idea unless you have very light hair already and even then, you will also need a lilac toner to remove brassiness. Store bought box kits are not strong enough, you will always be left with orange hair as red is the hardest colour to lift. This is really hard even for professional hairdressers. (I used to be one) Doing it in two stages is also a bad idea. Even with a timer, you will end up with banding, the colour difference where the edges meet. The only time I would ever say you might get away with it, is for pre-bleaching because you want to colour your hair a vibrant red.
