Your Hair Legacy-What Causes Hair Loss?
Your Hair Legacy
All of us, men and women, have a hair legacy which we need to preserve. Hair loss is often misunderstood. Hair is often regarded as a reflection of health. On average we have 100,000 to 150,000 hairs. People are sensitive about the quality of their hair. Very recent research has made it possible for science to understand the secret life of hair, from its birth to death.
Hair Physiology
MELANOCYTES: these cells supply the pigments which give hair its color. DERMAL PAPILLA: play a vital role in supplying the scalp with blood. HAIR FOLLICLE: this is a double sheath which anchors hair in the epidermis and dermis. SEBACEOUS GLAND: this gland helps keep hair permanently lubricated. HORRIPILATE MUSCLE: this muscle makes hair bristle in cases of stress. HAIR STEM: composed entirely of keratin-packed cells. CORTEX: hair color is determined by melanin located in the center of the hair stem in the cuticle (keratin filaments make up the structure of the cuticle). BULB: each hair is implanted in the skin by means of a bulb which is produced by a rich and important area, the matrix. MATRIX: a hair production workshop, the matrix allows germinal cells to divide rapidly so that older, keratinised cells are pushed outwards. The hair stems originate here.
The Hair Cycle
Hair is a living material and is therefore undergoes growth and death cycles.
