You may have a skin condition known as impetigo. It is usually first seen as a red point and develops into an ulcer thereafter ten days or so, and is finally healed. It may also spread to other skin areas on the body. This is the result of bacteria entering the body through small cuts or sores. In a clean environment, and with the help of antibiotic ointment, the skin can be healed. 

Dandruff is a COMMON scalp condition causing itching and flaking. Hair loss can be caused by GENETICS, stress, or illness. Maintaining good scalp hygiene can help reduce dandruff.

Eat a balanced diet rich in PROTEIN and VITAMINS for healthy hair..

This infection occurs when the skin is invaded by bacteria or fungus. Itching, redness, and pain are some symptoms that may be experienced. Keeping the area clean and dry could be helpful.

Your face might seem burnt from too much exposure to the sun, and this can be very uncomfortable. This occurs when the skin gets too much sun without protection.
