I wanted to know about my skin and more pigmentation and dark circles and sports and pimples small bumps

In the last few days it has increased and it seems that this pain is in the hair roots because it gives relief in moving them. It happens a lot at night and never in one place, like today on the left side, yesterday on the right side, in different places like this. Normally my hair fall is under 50 but the day the pain started increasing, I count almost 400 hairs in a day. This was after I used a good shampoo and when I applied oil. This pain is a mixture of itchiness. I get red pimples but very rare.

It's been 10 days I have 2 spits in my face and there are minor spots in legs ... Can it be cured? Is there anything to worry? Will it be spread on whole body? Kindly tell

Is hydrafacial good instead of going for regular parlour facials. Does the serums,medicines  etc used in it cause any side effects to the body.

I was diagnosed with genital herpes for the first time 3 years ago. Can I ever have sex with my uninfected partner without a condom? If not , how do I get pregnant ? I had only that initial outbreak and took treatment for a week. After that no outbreaks till date. Is it necessary that I'll infect my partner the moment we have unprotected sex? Also, please answer this. I was infected by my previous partner only after multiple acts , and not the first time we had unprotected sex. What's the explanation to this? Is it necessary that people will get infected the first time they have unprotected intercourse?
