During the shedding stage, the hair follicle rests completely for about 100 days. In average, up to 100 telogen hairs are shed everyday. Often, it is not the number of hair fall that causes thinning hair. Most of the times, it is the prolonged resting stage that causes the hair on the scalp to thin.
A study published in the Phytotherapy Research showed that Rosemary extract inhibited the activity of 5-alpha-reductase by up to 94.6%. By inhibiting the action of enzyme 5-alpha-reductase in hair follicles, rosemary extract reduces dihydrotestosterone (DHT) in hair follicles that helps prevent androgenetic hair loss.
A comparison study between the hair-growth-boosting properties of Rosemary Oil and Minoxidil showed that rosemary is equally as effective as Minoxidil in promoting hair growth in people with androgenetic alopecia. Rosemary contains phytochemicals that help prevent the conversion of testosterone to dihydrotestosterone.
As an anti-ageing scientist who studied at The Institute of Traditional Herbal Medicine and Aromatherapy (ITHMA), London; I am very fond of essential oils. For the past 15 years, I have been developing and perfecting haircare formulas to slow down my own hereditary hair loss.
According to Reuters (29-September-2019), U.S. Food and Drug Administration have received 5,000 complaints about the adverse sexual effects of finasteride from 2009 to 2018. 350 out of 5,000 men who reported these side effects were also suffering with suicidal thoughts. It was said that 50 of them committed suicide.
High Blood Sugar Levels trigger inflammation. Chronic inflammation is an autoimmune condition, the same type of condition that triggers alopecia areata. People who suffer from type 1 diabetes are at higher risk of suffering from alopecia areata, a hair loss condition characterised by smooth bald patches on the scalp.
Numerous studies with a total participant of 36,990 men showed that men with severe vertex baldness have a 48% higher risk of heart disease. A moderate vertex baldness was associated with a 36% increased risk of heart disease, while men with mild vertex baldness have a 18% higher risk of heart disease.
A study published in Toxicology Research suggested that peppermint oil is more effective than minoxidil in promoting hair growth. Peppermint oil has been shown to increase the number and the depth of hair follicles. After 4 weeks, Peppermint Oil improved the hair growth by 92% compared to 55% of Minoxidil.
In hair follicles, testosterone gets converted to dihydrotestosterone by the enzyme 5-alpha-reductase (5-AR). A study published in the International Journal of Trichology suggested that Caffeine may reduce the activity of 5-alpha-reductase. Hence, caffeine seems to help prevent the hair follicles from shrinking.
Dihydrotestosterone causes hair follicles to shrink gradually. Over the times, hair appears visibly weaker, shorter and thinner. The term of androgenetic alopecia is used for a hair loss condition caused by androgen hormones, particularly dihydrotestosterone. Left untreated, this hair loss condition may cause baldness.
