Beginning with the featured Pro Football Hall of Fame game in early August, five weekends of exhibition games are currently played in the NFL. The start of the preseason is intrinsically tied to the last week of training camp.
Nits are head lice eggs, they are very small, about the size of a knot in thread, hard to see, and are often confused for dandruff or hair spray droplets. Nits are laid by the adult female at the base of the hair shaft nearest the scalp and are firmly attached to the hair shaft. They are oval and usually yellow to white. Nits take about one week to hatch. Eggs that are likely to hatch are usually located within Â¼ inch of the scalp.
Use nit combs or cat flea combs to remove the lice and eggs. Because eggs can hatch for up to 10 days after they are laid, comb hair daily for two weeks after you find the last live head lice, to remove any young that have emerged.dult head lice are about 1/8 inch long, grayish, flattened, and wingless. Their legs are claw-like, designed to hold onto hair. These lice excrete partially digested blood which can appear as 'black dandruff'. Lice eggs, commonly referred to as nits, are whitish, oval and the size of a pinhead (1/30 inch long).
