Piedra is a superficial fungal infection of hair shafts, which presents with small nodules stuck-on to the shaft. Black piedra, caused by Piedraia hortae, is characterized by black-colored nodules and is common in the tropics, especially in individuals with long hair and poor scalp hygiene.
Lice eggs (nits) on hair shafts.
Nits stick to hair shafts and may be hard to see because they're very tiny. They're easiest to spot around the ears and the hairline of the neck.
Black dots correspond to remnants of hair shafts in the follicular ostia and cannot be removed mechanically. They are usually associated with other forms of broken hairs. The second trichoscopic finding is hair dye; if hair is improperly washed, dye can deposit on the scalp and may even penetrate the follicular ostia.
Also look for lice feces, that look like tiny black specks on your child's scalp. If you see black specks, care- fully examine the rest of the head for live lice. Eggs: Female lice typically attach eggs 1/2-inch from the scalp. There can be from a few to several hundred nits in a child's hair.
Hair follicles are part of your skin that are responsible for growing your hair. If you accidentally pull out a strand of your hair and it has a ball (bulb) on the end of it, you didn't pull out the follicle, and instead, you removed your hair root.

Nits (eggs) will be white or yellowish-brown. Nits are often more easily seen than lice, especially when the person has dark hair. Also look behind both ears and near the back of the neck. You may see lice or nits.
Head lice usually look grayish-white or tan in color, though they can camouflage. Adult lice are around the same size as a sesame seed. Lice eggs may look like tiny ovals on the hair shaft. Head lice are tiny parasites that live on the human head and feed on blood from the scalp.
Head lice should be considered in anyone who has an itchy scalp, or who has repeated skin infections on or around their scalp. There are many other causes of scalp itching that can be mistaken for head lice. These include folliculitis, psoriasis, eczema and dandruff, but they do not have the features mentioned above.
A common skin condition, folliculitis happens when a hair follicle becomes infected or inflamed. This condition may look like acne, often starting out as small red bumps. You can have folliculitis on your face, arms, back and legs. Mild cases can be cared for at home, while other cases are treated by a dermatologist.
Black dots, also called comedo-like cadaver hairs, can be found in almost 50% of alopecia areata patients and indicate disease activity. Trichostasis spinulosa is a follicular disorder resulting from the retention of numerous hairs surrounded by a keratinous sheath in dilated follicles.
Nematomorpha (sometimes called Gordiacea, and commonly known as horsehair worms, hairsnakes, or Gordian worms) are a phylum of parasitoid animals superficially similar to nematode worms in morphology, hence the name.
This is a tactile hallucination known as formication. People with this condition are convinced the bugs are real, even with reassurance from others they are a hallucination. This makes formication difficult to treat for the person and their medical provider.
Mites are extremely tiny round black bugs with no wings and eight legs. While they are rarely harmful to humans other than mild irritation to the skin or allergies, black mites in the house could signal elevated moisture levels or a more significant water issue. One of the most common types of mites is the Clover Mite.
Demodex is a type of mite that lives in human hair follicles, usually on your face. Almost everyone has these mites, but they usually don't cause any problems. But Demodex can multiply too quickly in people who are immunocompromised or have other skin conditions.
It can be tough to find a nymph or adult louse. Usually, there aren't many of them and they move fast. Look for nits attached to the hair near the scalp. They can look like dandruff or dirt.
Flea eggs are almost microscopic—typically about 0.5 millimeters in length and about half as wide. That's about the size of a grain of salt. Flea eggs have a soft shell called a chorion that has an off-white color, similar to a grain of salt, though they are more oval in shape.
Lice are about the size of a poppy seed, so they're usually too small to feel with your fingers.
Bacterial folliculitis.
This common type is a rash of itchy, pus-filled bumps. It occurs when hair follicles become infected with bacteria, usually Staphylococcus aureus (staph). Staph bacteria live on the skin all the time. And they can cause problems when they enter the body through a cut or other wound.
Feces — Look for lice feces on the scalp, which are tiny black specks. If you see them, examine the rest of the head for live lice. Eggs — Female lice typically attach eggs 1/4-inch from the scalp. There can be from a few to several hun- dred nits in a child's hair.
Black piedra is treated by using oral terbinafine. White piedra can be treated by using topical antifungals, including imidazoles, ciclopirox olamine, 2% selenium sulfide, 6% precipitated sulfur in petroleum, chlorhexidine solution, Castellani paint, zinc pyrithione, and amphotericin B lotion.
