As a specialist in the field of entomology, particularly with a focus on parasitic insects that affect humans, I can provide a detailed explanation regarding the life cycle of head lice and their eggs, commonly referred to as nits.
Head lice, scientifically known as *Pediculus humanus capitis*, are small, wingless insects that live on the human scalp and feed on human blood. They are highly adapted to this environment and are unable to survive for more than a day or two away from the human host.
The life cycle of head lice begins with the female louse laying eggs, which are firmly attached to the base of the hair shafts, near the scalp. These eggs, or nits, are tiny, oval-shaped, and yellowish-white in color. They are often found in clusters and are firmly cemented to the hair, making them difficult to remove without the use of special tools or treatments.
Once the eggs hatch, the nymphs, which are the immature form of the lice, emerge. These nymphs are very small and can be easily overlooked by the naked eye. They must feed on blood to grow and develop into adult lice. The process from egg to adult can take about 10 to 17 days, depending on environmental conditions.
Now, addressing the specific question: Can nits be dead and still attached to hair? The answer is yes. Once the eggs hatch, the empty shells, or nits, remain attached to the hair shaft. These shells are essentially the remnants of the eggshells after the nymphs have emerged. They are no longer living entities but are simply the empty cases that once contained the developing lice. As the hair grows, these nits move further away from the scalp, but they remain attached to the hair shaft.
It is important to note that the presence of nits alone does not necessarily indicate an active infestation. They could be empty shells from a previous infestation that has been treated. However, the presence of live lice or nymphs, along with nits, is a clear indication of an ongoing infestation.
Proper diagnosis and treatment are essential to eradicate head lice. This includes the use of medicated shampoos, fine-toothed combs, and other methods to remove both the lice and their eggs. It is also crucial to clean personal items and bedding to prevent reinfestation.
In conclusion, nits can indeed be dead and still attached to hair. They are the remnants of the lice eggshells after the nymphs have hatched. The presence of nits can be a sign of a past or current infestation, and appropriate measures should be taken to ensure a thorough treatment and prevention of future infestations.

Once the egg hatches, the spent shell (the nit) remains attached to the hair shaft, but it is white. As the hair grows, the nit grows with it and is farther from the scalp. Without the aid of a microscope or magnifying glass, it is hard to tell if the nit is alive, dead or hatched.
