Head lice
Head lice symptoms are similar to dandruff; you may experience an itchy scalp that leads to scratching. Eggs, called “nits,” cling to the hair shafts. These resemble small grains of sand that can be mistaken for dandruff flakes.
How to tell the difference between dandruff and nits:
dandruff will fall off the scalp and hair as flakes
nits cling to the hair firmly
nits have a specific teardrop shape
dandruff skin flakes can be found on scalp (where they form) AND hair
nits will be found only on hair fibers
Lice and nits can only be treated with manual combing and removal after washing your hair with anti-lice shampoo.
Sunburnt scalp
A sunburnt scalp shares some symptoms with dandruff including redness, irritation and itchiness. If you continually use hair dryers orother heat stylers, you may experience a burn on your scalp, which can cause these too.
How to tell the difference between dandruff and sunburnt scalp:
Sunburn flaking is concentrated where your scalp was exposed to sun: your part line or places where your hair is thin.
Dandruff flaking can occur anywhere on scalp, but especially in areas less exposed to sun.
A way to check your own hair for dandruff flakes is to part your hair near your temple (just above your ear).
The color of the flakes may also give you a clue; skin that’s peeling from sunburn is white, whereas dandruff flakes may be white or yellowish.
A sunburnt scalp needs to be treated with cooling aloe. You should refrain from using heat stylers until your scalp is completely healed.
Even then, try to limit their use as they can contribute to a dry scalp, damaging your scalp’s natural moisture defenses.
