A key aspect of hair loss with age is the aging of the hair follicle. Ordinarily, hair follicle renewal is maintained by the stem cells associated with each follicle. Aging of the hair follicle appears to be primed by a sustained cellular response to the DNA damage that accumulates in renewing stem cells during aging. This damage response involves the proteolysis of type XVII collagen by neutrophil elastase in response to the DNA damage in the hair follicle stem cells. Proteolysis of collagen leads to elimination of the damaged cells and then to terminal hair follicle miniaturization.
A hair growth cycle consists of three phases. During the anagen phase, hair grows actively. This phase may last for years. During the catagen phase, hair stops growing and separates from its follicle, which is the structure beneath the skin that holds the hair in place. The catagen phase lasts about 10 days. During the telogen phase, the follicle rests for two or three months, and then the hair falls out. The next anagen phase begins as a new hair grows in the same follicle. Most people lose 50 to 100 hairs per day as part of this natural cycle.
Stress: It’s no secret that stress can cause hair loss and an increase in the stress hormone cortisol may make you more likely to suffer from conditions like telogen effluvium, which causes more hairs than normal to fall out, or trichotillomania, a psychological condition in which a person pulls out their hair, like as a nervous (or stress-induced) habit.
Genetics is the most common reason for baldness, yes, but, according to this study in PLOS Genetics, it’s a more complicated process than we initially thought, and involves more than 280 genes. From this genetic map, researchers were able to determine which participants were in danger of losing their hair, and from those in the danger zone, about 20 percent could blame their mothers for such a predicament—not their father. Though, it is important to note that men and women lose their hair in very different ways. For men, the hair slowly begins receding at the temples, before eventually forming an M-shaped hairline, while women may notice a gradual widening of the scalp and thinning texture of their hair.
A medical event or condition, such as a thyroid imbalance, childbirth, surgery, or a fever, typically triggers this type of hair loss. Telogen effluvium may also occur as a result of a vitamin or mineral deficiency—iron deficiency is a common cause of hair loss in women—or the use of certain medications, such as isotretinoin, prescribed for acne, or warfarin, a blood thinner. Starting or stopping oral contraceptives (birth control pills) may also cause this type of hair loss.
2.Omega-3 Fatty acids -Omega-3 is an essential fatty acid that plays an important role in the maintenance of the cardiovascular system and tissue maintenance. Omega-3 can be found in fish oil supplements. Fish oil supplements are extracted from food sources high in omega-3, and deliver two potent fatty acids for the body. These are docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).Clinical studies have found that these omega-3 fatty acids can boost mental health, improving mental skills such as concentration, focus and memory. EPA and DHA can also help lower inflammation and reduce bad cholesterol, therefore reducing the risk of stroke and heart diseaseomega-3 fatty acids are extremely helpful for promoting healthy hair. Researchers publishing in Advances in Therapy analysed data collected from 30 women aged 38 to 67 years who had experienced hair loss. It was found that omega-3 significantly reduced hair loss in women.Other clinical studies found that lack of omega-3 can lead to opaque and dry looking hair which in turn can end in dandruff or an itchy scalp. Omega-3 contributes to lubricating hair follicles and so add elasticity and brightness to your hair.The best thing is that you’ll hardly struggle to eat an adequate amount of omega-3 in order to take advantage of its health-enhancing benefits. Two units of fatty fish alone provide the weekly recommended dose of DHA and EPA. The choice is vast: salmon, halibut, sardines, trout, catfish, cod, tuna and herring.Other dietary sources of omega-3 include nuts, flaxseed, shellfish, canola oil and eggs. An easy way to consume omega-3 is through fish oil supplements
decrease in your blood Prostate Specific Antigen (PSA) levels. Finasteride can affect a blood test called PSA (Prostate-Specific Antigen) for the screening of prostate cancer. If you have a PSA test done you should tell your healthcare provider that you are taking Finasteride because Finasteride decreases PSA levels. Changes in PSA levels will need to be evaluated by your healthcare provider. Any increase in follow-up PSA levels from their lowest point may signal the presence of prostate cancer and should be evaluated, even if the test results are still within the normal range for men not taking Finasteride. You should also tell your healthcare provider if you have not been taking Finasteride as prescribed because this may affect the PSA test results. For more information, talk to your healthcare provider.
Some hair loss is associated with stress although male pattern baldness is a genetic condition found in many men. If you find your hair is falling out in clumps or at unpredictable times, it is most likely to be the symptom of something else. This could be stress related but is unlikely to be caused by sexual frustration. The best thing to do is to see your GP for a check up.
