Is a flat iron safe on Brazilian blow out treated hair?!

Omg google literally won’t answer this question. Can I take a flat iron to my hair after its been brazilian blow out treated? I showered once with Maria Nilla which is supposedly sulfate and phosphate free but now my hair is frizzy again 💀 so I think I messed up. I have Brazilian blow out shampoo and conditioner to use from now on obviously

regardless can I use a flat iron on it with a heat protectant or will it completely undo the treatment
