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.
Pubic lice eggs are tiny, yellow-white ovals, which are stuck firmly to the base of your hairs. You may also notice the following symptoms: dark brown or black powder on your skin or in your underwear (this is louse droppings)
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.
Some common bugs that can be mistaken for lice are ants, bedbugs, and fleas. A few things all these bugs have in common is they're small in size, can be dark colored, and can give you an itchy head. A few things that can be mistaken for lice nits are dandruff, hair product, or dirt.
A dead lice egg will be white or grey. As they are empty, they will be flat and dry.
After each treatment, checking the hair and combing with a nit comb to remove nits and lice every 2–3 days may decrease the chance of self–reinfestation. Continue to check for 2–3 weeks to be sure all lice and nits are gone.
If a person notices bugs or black or brown spots on the scalp or in the hair, this usually means they have lice, not dandruff.
About head lice and nits
Brown-black nits are eggs that haven't hatched into lice yet. White nits are eggs that have already hatched.
Nits are often confused with other things found in the hair such as dandruff, hair spray droplets, and dirt particles. If no live nymphs or adult lice are seen, and the only nits found are more than ¼-inch from the scalp, the infestation is probably old and no longer active and does not need to be treated.
Dark spots
If you notice them on your scalp, don't be worried. It's time to be overjoyed! These dark spots indicate that your hair follicles are in the active phase of hair regrowth. So, these spots are a sure shot sign of new hair growth.
Body lice are flat wingless insects with six legs, each ending in a claw. They are greyish or brown in colour and range in size from 2mm to 5mm. Body louse eggs (nits) are small, white and oval-shaped.
Untreated head lice may degrade the scalp and affects it health and that of the hair. If the follicles become blocked, then hair loss may occur. It is hard to have well-conditioned hair if it is covered in head lice eggs, lice and bacteria.
Head lice eggs (nits) are brown or white (empty shells) and attached to the hair.
Dandruff, hair casts, globules of hair spray, and scalp conditions such as psoriasis or eczema may easily be mistaken for nits.
The life cycle of the head louse has three stages: egg, nymph, and adult. . They are 0.8 mm by 0.3 mm, oval and usually yellow to white.
Nits (eggs) that are over ½ inch (1 cm) from the scalp are empty egg cases. They are very white in color. Off the scalp, nits (eggs) can't survive over 2 weeks. Adult lice survive 3 weeks on the scalp or 24 hours off the scalp.
New eggs are attached to the hair shaft very close to the scalp. Eggs that still contain a louse embryo are brownish in color, while the empty egg shells are white to grey.
But unfortunately, the nits will not simply fall out your hair. The lice themselves take 7 to 11 days to hatch, so after that what is attached to the hair is the empty eggshell or the dead nit. These will stay attached to the hair and as the hair grows you will find them further and further down the hair shaft.
Although lice and their nits are small, you can see them with the naked eye. They can be white, brown, or dark gray. You're more likely to find them in the hair at the back of your neck or behind your ears. The nits are round or oval specks that are tightly stuck to hairs near the scalp.
Most eye floaters are caused by age-related changes that occur as the jelly-like substance (vitreous) inside your eyes liquifies and contracts. Scattered clumps of collagen fibers form within the vitreous and can cast tiny shadows on your retina. The shadows you see are called floaters.
Black specks occur when heat gradually degrades thermoplastic molecules, breaking them down into carbon residues. This commonly happens during machine shutdowns/startups. This is why most of our customers would call us with blacks dots issues on Mondays!
Detection combing can be carried out on dry or wet hair. Dry combing takes less time, but wet combing is more accurate because washing with conditioner stops head lice from moving.
Many people with head lice have no symptoms at all. It's impossible to diagnose head lice based on symptoms alone since the only symptom that matters is the presence of lice. However, experiencing the following symptoms suggests it is time to check the scalp: frequent unexplained itching of the head or scalp.
Head lice live only on your scalp or behind your ears and at the back of your neck. They can't live for very long anywhere else. But you can have other types of lice on your body, such as body lice or public lice. If you have itchy skin or think you've seen lice on your body, talk to a pharmacist or see your GP.
