A form of seborrhea, like dandruff, commonly found in infants, cradle cap is an inflammatory scaling disease of the scalp. Scales and/or flakes can appear in the eyebrows, around the nose and behind the ear.
Dandruff, is the surplus shedding of dead skin cells from the scalp. It most often occurs in the winter months and is exacerbated by excessive hair spray or gel use, dry indoor air, and infrequent shampooing. Dandruff is a natural process so it can be controlled but not removed.
Changes in the weather, dry air and medication can affect the moisture of your scalp.
This genetic predisposition to baldness can start with thinning hair between the ages of 25 and 35. New hair growth becomes thinner and finer, especially around the part on the top of the head.
Folliculitis is an infection and inflammation of the hair follicle. It can occur almost anywhere on the skin and is usually caused by the bacteria staphylococcus. Folliculitis first appears as scattered pimples and pustules that dry out and form crusts around the follicles.
Age, changing hormones and heredity can cause some people to lose more hair than others. The average head contains about 100,000 hairs, which are lost at a rate of 70 to 100 hairs per day. On most heads the hairs are replaced but as we grow older hair this process slows down.
Head lice are tiny parasitic insects that are 2 to 3 millimeters long–about the size of a sesame seed, which live by biting and sucking blood from the scalp. Once lice attach their eggs, called nits, to the hair, the eggs hatch in 8 to 10 days, producing more lice.
This skin condition most often appears on the scalp, elbows and knees. It occurs when areas of the skin grow at an increased rate causing the area to form red, scaly patches.
Seborrheic Dermatitis (Severe Dandruff)
This condition is very common and characterized by inflammation of the skin on the nose, scalp, eyelids and behind the ears because those are the areas with the highest concentration of oil glands. Often the skin will be covered in yellow, greasy scales that might cause mild itching. It is thought by some to be caused by yeast growing on the skin and it is believed those who have it are genetically predisposed to the condition.
