Hair issues

So I have always had nice thick hair (a curse and a blessing)

But the past month I’ve lost an insane amount of hair and my hair has been way more oily. I used to wash my hair once a week but now my hair feels oily after a day or two after washing it. Anyone else gone through this?😩 I just switched within the past week my shampoo from treseme to hairitage by Mindy daily shampoo.

And I’ve been using the Shea moisture conditioner for a little bit.

So I don’t think it’s been because of me switching shampoos cause that just happened more recently and I’ve had this problem for about a month now.

If anyone has suggestions on what to do/use a girl could use some help! These are the exact products I use
