    Hair types and morphology

    Some parameters and characteristics should be taken into consideration when assessing hair types and morphologies: shape, density and appearance. The appearance of hair, in the form of lanugo, occurs during the fourth month of pregnancy.     Hair types and morphology

    Structure and chemical composition of the scalp

    The scalp is an ultra-specialized area of the skin, where hair is anchored. Like other hair, also the hair on the scalp originates from a hair follicle, called a bulb.     Structure and chemical composition of the scalp
  • Hair loss

    Hair loss (telogen effluvium)

    With the term Telogen Defluvium we mean a modest, not excessive, loss of hair in the telogen phase, but which tends to often be irreversible, with the precise characteristics of hair in decay or involution. The hair that falls out is usually short and fine, with bulbs that are undeveloped and reduced in size.     Hair loss (telogen effluvium)

    Hyperhidrosis

    Excess sweat production on the entire surface of the body or just in some areas (especially the scalp, palms of the hands, soles of the feet) is called hyperhidrosis.Some of the causes that may lead to temporary hyperhidrosis are physical hyperactivity, fevers, saunas, vomiting and dysentery. Causes that may instead lead to a repeated state of hyperhidrosis are hyperthyroidism, hypoglycemia and alcoholism.     Hyperhidrosis

    Sebaceous glands

    The sebaceous glands are glands that secrete sebum, an oily, acidic substance with a pH of 3.5. They are connected laterally to the hair follicle. Sebaceous glands are found with a density of approximately 100/cm2 throughout all areas of the skin. In the human body, they are located across the entire surface of the skin, except for the palms of the hands and the soles of the feet. Sebaceous glands are also found in the external auditory meatus (ear canal) and on the eyelids, where they are long and flat. Here they are called tarsal or Meibomian glands.       Sebaceous glands

    Dandruff or pityriasis

    Dandruff is a scalp condition that usually arises between the ages of 10 and 25. It may improve between the ages of 45 and 55 or may continue during old age.Its cause is a result of an accelerated turnover of epidermal cells, which following an increase in migration speed, are unable to reach complete maturity before detaching. Whitish-yellow flakes (masses of corneum cells) form and detach, gathering in patches or often spreading evenly across the scalp.     Dandruff or pityriasis

    Dry hair

    Both men and women of any age may have dry hair. This situation is endured not only as an aesthetic problem, but in time may represent a problem concerning hair health. Dry hair often appears weak, fragile and tends to become brittle and to break.Dry hair often has split ends and other forms of damage to the shaft.     Dry hair

    Greasy hair

    Some parameters and characteristics should be taken into consideration when assessing hair types and morphologies: shape, density and appearance. The appearance of hair, in the form of lanugo, occurs during the fourth month of pregnancy.     Greasy hair

    Thin hair

    Genetic factors influence and determine hair diameter. Their volume varies from person to person. That’s why some people are born with fine hair, while others have thick hair right from birth. Hair diameter is a really important factor. Not only does it define their look, but it also gives us info about their health. Fine hair tends to be less attractive, less lively, weaker and more vulnerable than thick hair, so it’s more affected by external and internal factors.     Thin hair
