Thinning Hair and Hair Loss
Types and Causes
This page will help identify what is causing your thinning hair. Understanding what's at the root of your individual case of hair loss is paramount to stopping, perhaps even reversing it.
Types and Causes
of Thinning Hair
- hair loss due to sensitivity to male hormones (testosterone), present in both men and women. Heredity plays a role here, so if you're pre-disposed to hair loss, take action as early as possible to preserve what you have.
Male Pattern Baldness (MPB) is caused by testosterone coming into contact with the oil in the sebaceous glands on the scalp. When mixed they create dihydrotestosterone (DHT). This nasty little fella shrinks follicles, and restricts blood flow to the scalp. It also creates a coating on the scalp which impedes the few maverick hairs that do
manage to grow from amounting to anything.
Women's hair loss, or Female Pattern Baldness shows up as an over-all thinning, particularly in the top and crown. "The Ludwig Scale" is commonly used to diagnose women's hair loss stages.
- hair goes into a "resting period" and sheds excessively while growth is reduced to a minimum. Usually a result of trauma, acute illness, or post-pregnancy. Hair regrows in most cases within 6-9 months.
- effects a small area where the hair completely falls out due to immunological imbalances where the body's immune system attacks the hair follicles, mistaking them for foreign bodies. Usually remedies itself, although it can escalate into Alopecia Totalis (loss of all scalp hair), or Alopecia Universalis (loss of all scalp hair and all body hair).
