Are the parabens in cosmetics harmful?February 12, 2015
The follicles in your skin accumulate dirt, oil and other debris from hair products. Failing to stimulate and rinse out your follicles regularly can result in clogging that produces itching, redness, dryness, pimples and, in extreme cases, hair loss. A greasy head of hair can not only be difficult to control, often requiring daily washing, but in the most severe cases can lead to hair loss. The Androgens (male hormones) can genetically and specifically influence the activities of the Sebaceous Glands by over stimulating them to produce greater quantities of degenerated sebum which becomes keratinolytic, that is to say capable of destroying keratin and killing the hair. To control greasy scalps and Seborrhoea is important to reduce the actions of the 5 Alpha Reductase enzyme to normal levels, thereby limiting the levels of testosterone transformed into Dehydrotestosterone (DHT). The sebaceous glands are filled with specialized cells which multiply and produce the sebum. This process is part of the natural scalp function. When these cells are full they burst releasing their contents into the upper part of the hair follicle, near the scalp surface. The sebum, composed of various fats and the residues of the burst cells reaches the scalp and lubricates it. The sebaceous glands are under the control of hormonal processes. Androgen hormones (mainly testosterone) reach the sebaceous glands via the blood stream and on arrival are activated by the enzyme ‘5 Alpha Reductase’ which is found naturally close to the target organ, in this case, the sebaceous gland. On arrival testosterone is relatively inactive. It is only under the influence of the 5 Alpha Reductase that it is transformed into dehydrotestosterone (DHT), a very active form of the androgen hormone. This hyperactive form stimulates lipogenesis (the synthesis of fatty substances and sebum) within the sebaceous glands. This is known as scalp Seborrhea.
