Your scalp problem could be a medical issue that requires medical treatment. I recommend you should pay a visit to a dermatologist, who is a skin expert. They can detect the condition and recommend the medications or treatment option that should be taken. Avoid using any harsh chemicals on your scalp until you have been to a doctor.
 

Usually, cold sores appear as red, swollen bumps on or around your lips. They can hurt a little and may have clear fluid inside them. The virus responsible for cold sores is known as herpes simplex. You could try using over-the-counter creams or ointments to make them heal quicker. Always wash your hands and avoid touching the sore so it doesn't spread. 

Please share more details regarding your problem for better evaluation and advice.

Genital warts are caused by a virus known as HPV. It is impossible to be infected with HPV through the sharing of clothes, towels, or objects of personal hygiene. The most common way for HPV to spread is through skin-to-skin contact, usually during sexual activity. The general symptoms of genital warts are the presence of small, flesh-colored bumps in the genital area. In case you happen to be concerned about HPV then the best thing to do is to talk to a healthcare provider about preventing and treating it.

Creamy cleanser( low level of PH)  will be good for skin that is dry  and for part of your skin that is oily(nose) foaming cleanser will be good. But use moisturizer later. I hope this proved helpful.
