Is it ok to put conditioner in you hair as a deep conditioner?

Ok so I put my normal Pantene Pro-V Relaxed and Natural Conditioner i my hair every Wednesday as a deep conditioner then i let it soak in over night and rinse in the morning. it works really well for my hair since its damaged and permanently straightened. so my question is... is ok for what im doing? by the way please don't say just go buy a deep conditioner or a leave in conditioner just answer my question. thanks!
