How bad would it damage my hair if I semi-dye it twice within a 48 hour period?

Semi-dye dosent have any of those bleaching type chemicals though so i’m not sure if the whole wait a week period still counts

Im just going on personal experience.. But i would wait at least 48 hours..

It will damage your hair. Absolutely.

It depends how healthy your hair is though, before i dyed my hair blonde i had really healthy hair, and my hairdresser dyed it 8 times in one day to try and get it blonde(which she didnt even do properly) but none of my hair fell out. so i think it depends on weather you have strong hair or not, i supose, and also what colour your dying it? but maybe just to be safe you should play by the rules and wait a week? :/

well i have really healthy thick curly hair that i straighten buut do like deep conditoning at least once a week

I would say you should be fine, but I mean it’s up to you your hair may feel and be in bad condition after. But that’s a decision you will have to make.

i diffently agree with Georgia! You hair should be healthy. I would reccomend you dye it once for an hour, and then wait 30 minutes, and then dye it again. That is just so it will dye right. If you have any questions of what i just said, or just hair in general, please funmail me! :)
