Below are some common hair loss myths.
Myth: Losing an average of a hundred hairs per day is normal. Don’t worry about it.
Fact: It’s true only if you don’t have MPB (male pattern baldness). Everyone loses some hair each day. Some hair loss is a normal part of human hair growth.When a hair is released from a hair follicle, new hair growth should replace the lost hair. If you are experiencing male hair loss, the follicles which produce hair are in the process of shrinking. At this stage the hairs being produced are thinner and shorter. As time progresses these follicles die and no new hair are produced to replace the lost hair, and extensive hair loss begins.
Myth: You can increase the number of hair follicles by using drugs or other methods such as hair loss products.
Fact: No. The number and diameter of your hair follicles is completely out of your control. It is hereditary.
Myth: Cutting or shaving hair can cause faster hair growth, with more thickness.
Fact: No. Hair grows at an average rate of one centimeter a month. Because each hair shaft is slightly thicker at its base compared to its tip, hair can temporarily appear thicker for about a week after it has been cut.
Myth: Wearing hats can cause hair loss.
Fact: Unless the hat is worn so tight as to cut off circulation to the hair follicles, wearing a hat does not cause hair to fall out. Instead, hats can contribute positively by blocking the sun and preventing sunburn. Wearing a hat for too long especially in hot and humid climate, however, can contribute to the excretion and accumulation of sebum and oil on your hair.
Sebum is a waxy substance that is secreted by the sebaceous glands in your skin onto hair follicles. Over time, sebum can react with cholesterol to create a hardened sebum plug that cuts off oxygen circulation to the hair follicles and cause it to fall out. Sebum plug can also accumulate dirt and become a breeding ground for bacteria thereby contributing to hair loss.
Myth: Blow drying and frequent washing causes hair loss.
Fact: Unless they are done excessively, blow drying and washing your hair frequently will not cause hair loss.
However, heat damaged hair is often brittle and prone to shedding. Too much heat can also permanently damage hair follicles, leading to hair loss. Similarly, physical damage to hair due to overaggressive shampooing or toweling can lead to a hair loss condition called traction alopecia. Similarly, coloring hair, perming, and styling – when done properly – do not lead to hair loss.
Myth: There is nothing you can do to prevent or treat hair loss.
Fact: This last myth is probably the most misunderstood thing about hair loss. In the past, this was true – there was nothing that could be done about hair loss. But now, with advances in science and hair loss product research has increased understanding about the nutritional needs of hair, men and women no longer have to live with hair loss treatment.

People often have the mistaken notion that only males can lose hair and that alopecia is a physiological defect the gentle sex is exempt from. As a matter of fact, almost 20% of females in the world are in dire need of protection from the frightful menace of losing their beautiful hair. Most of them have never imagined that there is such a possibility in a woman’s life. First of all, there is the female pattern alopecia, which is somewhat similar to the male pattern baldness, though much less severe. Women seem now to be increasingly threatened by what is called diffuse idiopathic alopecia, the cause of which has not yet been definitely ascertained. It is an insidious disease which may not be apparent until about 80% of the hair is lost, and is then manifest as a diffuse thinning of the hair over the entire scalp.
Testosterone excretion has been shown to be elevated, and some theories have been put forward on this basis to explain this type of female alopecia. It is said that this type of alopecia is associated with seborrhea. Anyhow seborrhea should be controlled, no matter whether or not it is really the cause of the hair fall. It has also been suggested that estrogens should be taken internally. How effective this therapy is has not yet been determined. Another suggested treatment is low-dose interrupted courses of corticosteroids. It’s now not so wonderful as it once seemed to be.
In fact, the female who has lost part of her hair does not need to be a vegetarian in her diet. She should only be a vegetarian in medication.
It is noteworthy that Chinese angelica, is widely used in traditional Chinese gynecology as a medicine for curing diseases and a tonic for improving health. Its extract has the additional advantage of being able to penetrate easily through the skin and, for this reason, is employed very often as a transdermal passage promoter. In our case, the extract of Chinese angelica carries with it the extracts of the other ingredients to pass through the skin smoothly so as to reach the hair follicles that need regeneration and to pervade together with the other ingredients the environment of hair follicles inside the scalp and provide them with added nutrients. Of these other ingredients, special mention must be made of the tuber of multiflower knotweed, which is reputed to possess a wonderful power of enabling hair to regrow. It has the popular nickname of Blackhead. This nickname came from a folk story, which runs as follows:
Many years ago an old man was stranded on a desolate island as a result of shipwreck. He had to live in a cave and depend on the tuber of multiflower knotweed as his staple food for more than ten years. Fortunately, a ship sailed by and noticed his signal for help. He was saved and carried back to his native village. His fellow villagers were surprised to find that his white hair had turned black. He attributed this change to the tuber of that herb on which he had subsisted.
As no one ever made any experiment to test the truth of the story by subsisting on the tuber for ten years, what the old man related to the villagers remains a folkstory. However, the nickname that has been given to the herb shows that Chinese people believe that the herb has the ability of rehabilitating hair.
