I've had this too I've been threw lots of tests nothing was found so I decided to not use anything in the bath but feminine wash and only a very little from super drugs own make unscented I use it on my body too and I never wash my hair Wen I'm washing my body I use sensitive washing powder and conditioner make sure I rinse really well I still have it occasionally but it's much better I think I was sensitive and because I was becoming dry it was making it much worse sometimes I've gou d certain foods flare me up too so I don't know if it's all connected like me but anything is worth trying because I know it's awfull living eith it
