I got chemical henna applied, not knowing it sets a layer on skin,i found out about it after some days, i had done ghusl to remove major impurity(menses) in those days, is the ghusl and prayers following it not valid meaning i do ghusl again with tayammum? i hope this can be excused and valid due to ignorance.. note: this layer can be felt and be peeled off on some of the parts, others not

The ghusul is invalid and one must repeat it and perform tayammum for not washing that area covered by this layer.
