What hormone could be affecting hair growth and thinning of hair shafts, and dry skin ?

Hi, I’m a 41 year old F, normal weight for my height. Around 5 months ago I went through a horrible trauma and developed severe DPDR where I mostly loose sensation in my body and my nervous system has taken a huge hit. It it like it is barely there any more it is so sensitized. I think it is secere CNS sensitization…Prior to the traumatic event I had pmdd and ptsd and GAD. I am also peri menopausal. I have done blood tests around 8 weeks ago and they were ok. But my skin, hair have drastically thinned, Ive lost elasticity in my skin and I feel awful. Very depressed and sad about the state of my nervous system. The dry dry scalp and incredibly thin, brittle hair are really bothering me. I used to have an oily scalp and thick hair only 6 months ago so it is a drastic change. I would like to undertand what could be the cause of this, what hormone imbalance could cause this or vitamin deficiency? Of course it is related to the trauma and the breakdown of my nervous system but I’d like to undertand whats going on hormonally and what tests I could do and what may help. Then I can figure out with a doctor. Im due to start HRT, an estrogen patch and combined soon. And considering an antidepressant because my brain must not be producing enough of something.
