What Causes Hair Loss?
Hair loss is usually hereditary but can be attributed to other life style factors such as stress levels, diet and exercise among many others. These factors may contribute to an unhealthy scalp that further leads to thinning and loss of hair.
A major cause of hair loss is the mixture of micro pollutants, residue from hair care products, and sebum clogging your follicles. Sebum is an oily substance produced by your skin. Sebum really have an important role in better condition of your hair scalp, but extra production of the sebum is resulted stress.
The sebum reaches on surface of scalp and mixes with dirt and hair care product residue. Because the sebum is now on your hair and scalp and exposed to air, it hardens (oxidizes) and creates a black tar-like substance. This hardened substance clogs your hair follicles.
The bacteria in this substance damage the follicle and are one of the major causes of hair loss. The result is blockage of nutrient absorption to the follicle, which impedes hair
Hormones and DHT
The most damaging process in hair loss occurs next. It happens to everyone. When testosterone mixes with the sebum or dirt substance that is now impacted in your follicle, it creates a powerful substance called
dihydrotestosterone, or DHT.
What makes this worse is that your body’s immune system senses the follicle is dying and as a part of its defense system, tries to further shut it down and get rid of it (as it would a cold or flu). What effect does the dying, clogged follicle have on an actual hair strand? If you pulled out a hair strand from your follicle, and looked at the root end of the hair strand under a microscope, you would see the hardened sebum or dirt substance on the root of the strand (we encourage you to do this so you can see for yourself!). What you are seeing is just a small amount of this material. The rest of it is your hair follicle.
At the root of every strand of your hair is a bulb. On a healthy strand of hair the bulb is nicely rounded. This healthy round shape is like a strong root, the larger the bulb; the more firmly your hair is rooted in your follicle. When sebum builds up in the follicles it deteriorates the bulb of the hair. Slowly, the bulbs get smaller, less round, and because of this, your hair is not rooted as well as it should and the hair strand falls out. Then another hair strand grows from the follicle, but this hair strand is thinner and weaker than the last one because of sebum blockage and the fact that the follicle is dying. This causes the hair strand to be thinner and the bulb smaller. The process repeats itself, with the next getting thinner and the bulb smaller each time the old one falls out.
This is why most men and women experience thinning hair as they are losing it. The unfortunate ending is a hair so damaged from sebum, bacteria, DHT production that the follicle dies.
