In short, testosterone converts to DHT with the aid of the enzyme Type II 5-alpha reductase, which is held in a hair follicle's oil glands. Scientists now believe that it's not the amount of circulating testosterone that's the problem but the level of DHT binding to receptors in scalp follicles. DHT shrinks hair follicles, making it impossible for healthy hair to survive. The hormonal process of testosterone converting to DHT, which then harms hair follicles, happens in both men and women. Under normal conditions, women have a minute fraction of the level of testosterone that men have, but even a lower level can cause DHT- triggered hair loss in women.

How does DHT effect hair growth?
- When DHT reaches the hair follicles and dermal papilla, it prevents proteins, vitamins and minerals from providing the needed nourishment to sustain life in the hair of these follicles.
- The hair follicles reproduce at a slower rate and shortens the growing phase of the hair follicles or lengthens its resting stage.
- DHT is responsible for shrinking hair follicle with which the hair follicle gets smaller and finer. This is how DHT is responsible for about 95% of hair loss. The men or women who lose more hair are those who are genetically pre-disposed in producing more DHT than others.
- DHT tends to create a wax like substance around the hair roots; the accumulation of DHT in the hair follicles and roots that gives rise to male and female pattern hair loss.

Natural DHT Blockers
There is Type 1 5-alpha reductase and Type 2 5-alpha reductase. Type 2 is the hair killer. There are two forms of 5a-reductase, and type I is the enzyme in higher amounts around the body, but it is the type II enzyme, which is thought to be responsible for most of the DHT formed in the hair follicle. Some studies show that both type 1 and 2 have negative effects on hair growth.
Green Tea
Green tea is a natural dht blocker that many are using successfully to solve hair growth problems. An infusion that's made from the leaves of the Camellia sinensis bush, which are rushed from the field to the processing plant as soon as they are plucked. There the leaves are steamed or pan-fired immediately to prevent them from fermenting. These unfermented tea leaves contain large amounts of catechins, which are powerful disease fighters and potent antioxidants. And green tea is the only natural source of large amounts of catechins (substances found in green tea which have powerful antioxidant and disease-fighting properties. They belong to the flavonoid family which, in turn, belongs to the larger family of the polyphenols.).
Researchers from Seoul National University College of Medicine in Korea decided to try to find out. For a study published in Phytomedicine in 2006, they measured the effects of green tea’s EGCg on the growth of human hair follicles in a test-tube environment.1 They also looked at what happened when EGCg was applied to dermal papilla cells (DPCs), cells that live in the hair follicle itself and play a key part in hair growth. EGCg not only stimulated the growth of DPCs in both test tube cultures and the human scalp, it also promoted the growth of the hair follicles. The researchers concluded that EGCg stimulates human hair growth by increasing DPC proliferation and slowing the rate of cell-programmed death. In my opinion, Green Tea looks like an effective natural DHT blocker.
