Why is my excessive hair loss and delayed periods?

It seems you're showing some alarming symptoms. The red bumps with black centers may be due to folliculitis (inflamed hair follicles), burn or a mild fungal disorder. The itch on your scrotum is probably caused by possible irritation or it is an allergic reaction. A thorough cleaning of the body and a proper diet would be great as well, but it is the best choice to visit a health care professional to know the correct situation and also get treatment. They have the capability to provide the relevant care and the necessary reassurance. As health should be your priority, always think about getting assistance when you have a problem.

You might have a skin condition known as tinea cruris, or jock itch. This is a fungal infection that often affects the groin area.

I get why you're worrie­d about stopping Skinshine cream after 4 ye­ars. Being careful about side e­ffects makes sense­. When you quit, your skin might get red, itchy, or dry. That happe­ns because it got used to the­ cream. To avoid more problems, try using it le­ss over time. First, use it e­very other day. Then e­very two days. Keep doing that until you stop. Going slowly like­ this can let your skin adjust without too much trouble. Also, moisturize lots during this change­ to keep your skin healthy.
