Androgenetic Alopecia. This is the Hair Envy Review grandmother of all women's hair loss. Also known as female pattern baldness, this type of hair loss involves the nasty hormone dihydrotestosterone, more commonly referred to as DHT. This wicked little monster binds itself to your hair follicles and prevents them from absorbing nutrients from your bloodstream. In essence, it chokes your hair to death.
Nutrient Deficiencies. B-vitamins, magnesium, protein, iron, and zinc must all be in ample supply within your body for your hair to thrive. If you're not getting enough of any of these, your hair follicles will weaken and eventually die.
Hormonal Imbalance. Events such as pregnancy, childbirth, menopause, surgery, emotional trauma, bodily injury, drug abuse, and thyroid dysfunction can directly contribute to your hormones getting out of whack, which can in turn rob you of your beautiful locks.
Poor Alkaline to Acid Ratio. The pH balance of your blood determines a lot of things. First of all, if you become far too acidic, you die, plain and simple. Less extreme amounts of acidity will cause other things to die. Your hair is no exception. Look into the works of Dr. Robert O. Young to gain a clear understanding of this extremely important scientific principle.
