Lice: increasingly resistant to chemical insecticides

In recent years lice have developed resistance to chemical insecticides, which are often neurotoxic and very irritant to the scalp. A lice killer based on organic and natural ingredients combined with the lice comb, are the key complements to be able to remove head lice and nits.

How to eliminate lice and nits?

Very likely you’ve ever wondered how to effectively remove lice from your hair, but what are head lice? Why do lice and nits adhere to your hair? What is the life cycle of lice? We tell you everything about head lice infestation (pediculosis) affecting the scalp.

Head lice (Pediculus humanus capitis) are blood-feeding parasites in humans.

Head lice and nits have been present since ancient times and are a public health problem worldwide. The majority of people affected by head lice are children between 3 and 13 years of age from all socioeconomic levels.

Head lice are small insects, visible to the naked eye, that live in people’s hair and feed on blood. At the end of their 6 legs they have claws used to adhere to hair. Female lice start laying three to ten eggs (nits) daily and have got a life cycle of about 1 month.

Why does my head itch?

Nits are attached to hair by a cementitious-like substance placed by the female louse and are incubated by the individual’s body warmth. After approximately seven days, a very fragile larva is born, which immediately must ingest blood in order to live. Nine days later, this reaches adulthood. When head lice feed on blood they inject saliva into the scalp giving rise to an irritation characterised by itching and stinging pain.

How do head lice spread?

The most frequent way of transmission is direct, from head to head, although it can occur through: combs, brushes, caps, scarves, headphones, headrests, mattresses, plushes, etc.

What are prebiotics, oligosaccharides and how do they benefit the scalp?

Human skin and its components (hair) provide a variety of microorganisms an environment fit to live in. The skin flora has got a beneficial and protective role, but any disturbance in its structure leads to a variation that can be “exploited” by pathogenic organisms to colonise. Fortunately, prebiotics such as oligosaccharides are “food” for the beneficial flora, as though they were ingredients that positively affect the individual’s skin. Oligosaccharides are beneficial to the scalp because they selectively stimulate the growth of a limited number of organisms which have got the potential to improve skin structure, so they benefit the scalp flora.

Long chain polyunsaturated fatty acids are important in regulating the functions of the brain, heart, membrane, retina, liver, kidneys, skin and mucous membranes, among others. In other words, they are essential for the maintenance of health.

Hyaluronic Acid to rejuvenate your skin and joints

Hyaluronic Acid is increasingly popular in beauty and wellness treatments. It is a component naturally present in our body, essential to maintain hydration in organs such as the skin and lubrication in joints, bones and cartilages. However, the passage of time and external factors like Ultraviolet radiation and environmental pollutants reduce the percentage of Hyaluronic Acid in our organism.

Iron, essential mineral for our body

Iron is an essential mineral that performs very important functions in the body. Iron allows the formation of haemoglobin, protein in red blood cells, which transports oxygen to the body’s tissues. Furthermore, it improves blood quality and increases resistance to stress and illness, prevents fatigue, and stimulates healthy skin.
