About Hair and Hair Care
The information provided is a intended to provide general information about hair growth, loss, and care. We recommend you seek the advice of a licensed stylist to address any special concerns you may have about your hair.
Hair Growth
Hair is composed of dead skin cells, dehydrated and filled with insoluble proteins (keratin), held together by strong attachments between the cells. Hair grows from a follicle root below the scalp at a rate averaging 10-15 mm per month. Hair grows in stages. 90% of scalp hair is in a continuous growth stage known as Anagen lasting 2-6 years. The other 10% is in the dormant or rest stage known as Telogen lasting 2-3 months. Because skin cells are constantly renewing themselves, flaking (dandruff ) occurs. Excessive dandruff may signal a medical condition such as psoriasis or eczema, or may be caused by improper cleaning, fungus or bacteria.
How Hair Becomes Damaged
Chemicals used to alter hair such as perms, relaxers as well as hair coloring agents are the most common causes of hair damage. These chemicals produce abnormalities to the hair and can interfere with hair production. Prolonged exposure to the elements and certain chemicals found in water can also damage hair. Mechanical forces such as combing, brushing, heat drying and styling and improper braiding and weaving can also damage the hair and scalp. Hair damage is not always limited to the existing hair; changes may occur in new growth. When the scalp is irritated or injured a condition known as Telogen Effluvium may result; the hair sheds abruptly and does not regrow for many months. In severe cases, hair growth may be permanently impaired.
Hair Loss
Some degree of hair loss will occur with hair that has been weakened by chemicals and/or mechanical forces. Other causes of hair loss include:
Perms and Relaxers
Chemical agents are widely used to add curl to straight hair and to loosen curls in curly hair. These products defat the scalp and permanently alter the structure of the hair. These compounds can also cause severe hair loss from over processing. Never use perms or relaxers on damaged hair. If possible, allow the hair to regrow before introducing new chemical processes.
