Normally 6 to 8 weeks is recommended if you are trying to grow your natural hair. The max is 4 months, if you have a full weave, the weave may still look good, but your hair underneath. Hair texture can inhibit your hair to either stay up longer than the recommended time frame or it’ll need to be taken out sooner. Women with thicker hair can go the max of 4 months, where as women with silky/fine hair can go half the amount of time. Matting, tangling, and dreading can occur, this can lead to hair loss in result of leaving your weave in too long.
