Weird pregnancy change

I wanna know who else this has happened to lol. So I am someone who has very oily skin and hair. Like my hair gets so greasy that it’s already greasy the day after I wash it and I have to use dry shampoo and then wash it the next morning. I’ve always had this hair type I just can never control the crazy amount of oils my scalp produces. Well I noticed this past month or so (I’m 29 weeks pregnant) my hair hasnt been greasy and I can go to day 4 before I feel like I need to wash it lol. And that’s not even using dry shampoo. It’s so WEIRD lol. I’m loving it though because I hate having to wash my hair every other day because it’s so greasy 😂
