Many theories exist as to why people suffer from hair loss. These hypotheses vary in scope. There is, however, one similarity to all the reasonable hypotheses put forth: deprivation, in some form, to the follicle and scalp leads to damaged and dead hair.
In general, as can be seen by the formulation of our products, Kevis subscribes to the idea that the conversion of the hormone testosterone into DHT, and the subsequent binding of this molecule to its receptor sites in the hair follicle as the primary agent of hair loss. Most modern medical research sides with this position. |
Hair follicles go through three phases of hair production as shown in the diagram above. These are Anagen, a growth phase which lasts from 2–6 years; Catagen, a transitional phase which lasts only 1–2 weeks; and finally, Telogen, a resting phase which lasts up to 2 months. The hair is then shed and the follicle begins pushing a new hair to the surface.
DHT causes hair follicles to go into their Telogen resting phase faster and remain dormant longer which causes hairs produced by affected follicles to become thinner and weaker with each growth cycle. Affected hair follicles generally contain a larger number of DHT receptor sites where the molecule can actually plug into and attack the follicle.
In male pattern hair loss, each successive cycle results in the production of weaker hairs being produced by the affected follicles, until the hair never breaks the surface of the skin. Once DHT binds to large numbers of receptors of the hair follicles of the scalp, the follicles are shut down and lie dormant.
The role of DHT receptor sites in hair loss also linked to genetics and hormonal influences since each hair follicle has a predetermined amount of sites that DHT can attach to. In a study comparing the follicles between hair-covered and bald male scalps, it was found that bald scalps had twice as many sites for DHT as their covered counterparts.
Hormones also play a role in hair loss. At birth, each of us has a certain number of hair follicles (roughly 100,000 on the scalp). In the case of male pattern baldness, it appears that those follicles positioned over the crown and front of the head, the infamous balding horseshoe, are usually sensitive to DHT.
Also, in cases of hair loss in women, DHT is also responsible as women produce testosterone just like men, but in smaller amounts. This actually leads to often an overall thinning of the hair as middle age approaches.
Other reasons for hair loss in women are: hormonal imbalances due to puberty or menopause, pregnancy, postmenopausal trauma, birth control. Even nervous tension and various medications and treatments can stimulate hair loss.
Surgeries and certain prescription medications may also bring about hair loss.
Women frequently experience hair loss gradually over time with harsh commercial shampoos, perms, hair color, bleach, and other cosmetic applications.
There is also another reasonable theory having to do with the angle of follicles and natural oil and wax build-up. The angle at which hair protrudes from a female follicle allows for the wax or oil produced by the scalp to "run off" while the angle of eruption from the male scalp can lead to oil blockage creating problems for follicular respiration and hair growth.
Poor circulation and nutrition can also restrict hair growth. A study of young men diagnosed with male pattern baldness showed that the blood flow to their scalp was 2.6 times lower than in the normal control group.
In many individuals the extremities, including the top of the head, are the most difficult places to maintain blood flow. Follicles which are constantly deprived of blood, and therefore nutrients, cannot produce hair properly. Lack of proper nutrients, amino acids, minerals and vitamins can certainly hamper hair growth.
Hair loss is a concern for many men. Some are already experiencing receding hairlines and other signs of impending hair loss and eventual baldness by their late teens or early twenties. Middle-age men almost always have some degree of hair loss or thinning.
By recognizing the importance of hair loss prevention and confronting the problem in its earlier stages men and women alike can use Kevis to keep the hair they have and bring about a rejuvenation and promotion of healthy hair growth and follicular development.
