Soy Isoflavones and Green tea TOGETHER severely reduce DHT

[RK85]

Wrong, which is why I asked for source. Green tea by itself is long known in the context of hair loss prevention, as it increases SHBG levels. Increased SHBG levels lead to less unbound T in your body, and thus to decreased DHT levels. The problem is that the SHBG increase from drinking green tea is not even remotely enough to halt hair loss, but green tea may be a component of your regimen to further slow it down. Little effect is better than no effect.

benjt, "T" means testosterone? I ask because on this website I have read that raising testosterone is good for hair:

Saw Palmetto Phytosterols in combination with Astaxanthin:Research conducted by Triarco, an American Biotech company, found that this combination not only lowers serum DHT, but Estrogen as well. In addition it was found to raise Testosterone, giving a multi-hormonal benefit for both hair growth, libido, and overall health.

So high testosterone is really good for hair?

Soy isoflavones, due to their phytoestrogen components, also have an effect of their own. High intake has indeed been linked to fertility problems (as a result of T and DHT decrease), as is to be expected when consuming high amounts of phytoestrogens. In fact, a soy based diet can significantly slow down hair loss (again to be expected if soy isoflavone effects are strong enough to even cause fertility problems).

Unfortunately the fertility problems aren't the only side effect of the soy.

The main point, however, is: Your statement that green tea only works in conjunction with soy isoflavones (or vice versa) is wrong. Please validate your statements before you make them, or provide source. You are making a lot of oversimplified statements which are simply not true.

Do you think the green tea extract and black tea extract are better than green and black tea? Is it true that one pill of extract from tea contains much more concentration of some ingredients (for example theaflavins, catechins - including EGCG) than one cup of tea?

This EGCG is something good for hair:

Green tea is a popular worldwide beverage, and its potential beneficial effects such as anti-cancer and anti-oxidant properties are believed to be mediated by epigallocatechin-3-gallate (EGCG), a major constituent of polyphenols. Recently, it was reported that EGCG might be useful in the prevention or treatment of androgenetic alopecia by selectively inhibiting 5alpha-reductase activity. However, no report has been issued to date on the effect of EGCG on human hair growth. This study was undertaken to measure the effect of EGCG on hair growth in vitro and to investigate its effect on human dermal papilla cells (DPCs) in vivo and in vitro. EGCG promoted hair growth in hair follicles ex vivo culture and the proliferation of cultured DPCs.

400mg Green tea extract (containing 200mg EGCG)

Theaflavins in black tea are also good for hair:

Black Tea (Theaflavin) Extract:Studies in both humans and animals have documented the ability of Theaflavins to reduce serum/plasma DHT, reduce Estrogen and raise Testosterone, with a noted increases in libido and male function. Its ability to lower DHT levels by 72% are almost identical to that of Proscar,( a higher dose of finasteride of 5mg, vs 1 mg finasteride for Propecia) and superior to that of Propecia, which lowers serum DHT by 65%. Unlike either Proscar or Propecia, both Theaflavins and Green Tea Extract also provide additional anti-inflammation effects that are beneficial for hair.

So the more theaflavins and catechins in the the tea/tea extract the better?
