Excessive hair loss is usually brought on by issues with hormones that happen post-partum and in the course of perimenopause and menopause and also by heredity. Vitamin deficiencies, certain illnesses and medications can also result in falling hair or hair thinning.

A person has somewhere around 110,000 hair strands if he or she has brown colored hair, 140,000 hair strands if blond, 108,000 hair strands if black and 90,000 hair strands if the color is red. For that reason, thinking about these quantities, shedding 50 to 100 hairs every day in the course of random hair rotation on the scalp is not a big deal.

Our Hair Experiences Cycles

At any moment, approximately 90% of our hair keeps on growing. This period of growing will last from 2 to 6 years. The remaining period is the resting phase of our hair. The resting phase will last about 2 to 3 months. Whenever the resting phase ends, the hair drops and fresh hair grows.

If a noticeable and significant amount of hair is shedding off each day, it could only mean that you are developing a telogen reaction. Telogen also means resting phase. Telogen effluvium happens when the hair loss is stimulated by physical or psychological stress that really affects the person that it boosts the quantity hairs that enter into the resting phase simultaneously. Occasionally after surgery, an individual's hair will fall out because of anesthesia or due to losing a significant amount of weight too fast. This loss of hair should be short-lived. Telogen responses can also be brought on by crash dieting or medications.

If an individual is not receiving sufficient nutrients or vitamins into his system, this will have an impact on his hair. If a person is lacking iron in the blood or anemic, it can also cause hair to fall our or thin greater than normal. It could also be that you are going through a faster phase of MPB or male pattern baldness.

Women may go through substantial hair loss 3 months after having a baby. This happens because the normal quantity of hair has not dropped out during the course of pregnancy. When the levels of estrogen are elevated while being pregnant, hair becomes abundant and full. The hair may not be growing any faster, however it is not dropping out at the usual rate. When the levels of estrogen in women go back to typical post-partum then she may observe hair loss. This condition is temporary.

If a terrifying quantity of hair is tangled in your comb or hairbrush and goes down the bathroom drain after you take a bath, it may be due to the fact that you possess a dry scalp. Scalp that is dry can trigger hair loss, if not taken care of. Hair coloring can also cause hair loss. If your scalp is allergic to the chemicals used in the process of coloring your hair, this can result in falling hair.

A number of people simply go through more hair fall compared to normal rate simply because of their own genes. Because of heredity, baldness can be handed down to children. The type of hair loss most commonly caused by heredity is MPB or male pattern baldness, and typically becomes obvious about the age of forty. There are a number of medications that can treat this condition.

No one really wants you to calculate the amount of hairs falling out of your head, but if you all of a sudden have been realizing your hair loss to be less than normal, it certainly signifies that it has sped up. Talk about this with the expert or your doctor and find out what hair loss treatment they recommend.
