Resumen:
Pediculus humanus
capitis attach eggs (nits) to the hair by a sort of
?cement?. The physical removal of nits has become an important part of the treatment
of louse infestations. The development of
new products to loosen the nits is necessary to avoid mistaken diagnosis or
reinfestations. However, there are a lot of over-the-counter products with no
nit remover effect due to the use of wrong active ingredients or formulations.
This work aims to compare different kinds of
pediculicide formulations in order to see if their presentations produce
differences in the nit remover effect. Hairs with head louse nits were
collected from infested children from 6 to 12 years old in schools of Buenos
Aires, Argentina. Our device consists in a kind of weighting scale that let us
measure the weight required to cause nits to slide along hair shafts. The
set-up includes a small metal plate; an aluminium container, little scales, a
stand and a holder. We tested three different formulations of Argentinian over-the-counter
commercial products: gel, cream and a hydro-alcoholic presentations. Besides,
we use an international silicone- based pediculicide and every day-use-products
such as the well-known vinegar and hair conditioner. We found that those
products with creamy presentations showed better nit remover effect than the
rest. We also found that vinegar is a good nit remover as well as a product
containing dimethicone.
