GTE (Green Tea Extract) and GSE (Grape Extract) are effective antioxidants, and may have some hairloss benefits too. Topical GTE is excellent for reducing scalp irritation and inflammation.
Here are a couple of interesting extracts to give you a heads-up
(Green Tea) - Mechanisms of cancer and hairloss prevention by tea polyphenols based on inhibition of TNF-alpha expression. Suganuma M, Sueoka E, Sueoka N, Okabe S, Fujiki H. - Saitama Cancer Center Research Institute, Japan.
Of greatest interest to those with androgenetic alopecia is evidence that green tea can influence serum concentrations of hormones and inhibit TNF-a. Research in this area is primarily with reference to hormonal effects on the development of cancer and how green tea and other caffeine containing products might mediate changes in hormone levels.
For example, high intake of green tea has been associated with higher levels of sex hormone binding globulin (SBHG) and lowered levels of serum estradiol (estrogen) concentration in women (Nagata 1998). Increased SBHG may be of help in reducing the effects of androgenetic alopecia. SBHG is a molecule that binds with high affinity to testosterone. Testosterone bound to SBHG is not bioactive and cannot bind to androgen receptors or be converted into dihydrotestosterone.
An increase in SBHG concentration effectively reduces free testosterone. green tea may also have an affect on the type I 5 alpha reductase enzyme that converts testosterone to dihydrotestosterone. These two distinct, but complementary, effects of green tea may influence androgenetic alopecia.
One cup of green tea roughly equals 50 mg of tea catechins. Typically research investigations have involved individuals drinking six cups of green tea, or utilizing green Tea Extracts (300mg or more catechins) each day. green tea is well tolerated by most individuals with no significant side effects reported.

(Grape Seed) - Procyanidin oligomers selectively and intensively promote proliferation of mouse hair epithelial cells in vitro and activate hair follicle growth in vivo. J Invest Dermatol 1999 Mar;112(3):310-6 Takahashi T, Kamiya T, Hasegawa A, Yokoo Y. (Tsukuba Research Laboratories, Kyowa Hakko Kogyo, Ibaraki, Japan.)
We have previously reported that proanthocyanidins extracted from grape seeds possess growth-promoting activity toward murine hair epithelial cells in vitro and stimulate anagen induction in hair cycle progression in vivo. This report constitutes a comparison of the growth-promoting activity of procyanidin oligomers and the target cells of procyanidins in the skin.
Results show that procyanidin dimer and trimer exhibit higher growth-promoting activity than the monomer. The maximum growth-promoting activity for hair epithelial cells with procyanidin B-2, an epicatechin dimer, reached about 300% (30 microM) relative to controls (= 100%) in a 5 d culture. Optimum concentration of procyanidin C-1, an epicatechin trimer, was lower than that of procyanidin B-2; the maximum growth-promoting activity of procyanidin C-1 was about 220% (3 microM). No other flavonoid compounds examined exhibit higher proliferative activities than the procyanidins.
In skin constituent cells, only epithelial cells such as hair keratinocytes or epidermal keratinocytes respond to procyanidin oligomers. Topical application of 1% procyanidin oligomers on shaven C3H mice in the telogen phase led to significant hair regeneration [procyanidin B-2, 69.6% +/- 21.8% (mean +/- SD); procyanidin B-3, 80.9% +/- 13.0%; procyanidin C-1, 78.3% +/- 7.6%] on the basis of the shaven area; application of vehicle only led to regeneration of 41.7% (SD = 16.3%).
In this paper, we demonstrate the hair-growing activity of procyanidin oligomers both in vitro and in vivo, and their potential for use as agents to induce hair growth.

Great green tea info, thanks. When my hair stopped falling out, I was drinking around 10 cups of green tea a day. I am sure it had something to do with it after reading that information.
Also, only buy green tea from a health food store. Supermarket, or cheap green teas offer no benefit. The best can be found in chinese grocery stores though.

Your body does not know the difference between tea that you drink and tea taken in a pill form. Same with any supplement, example-the body can not tell the difference betwen vit. C from a fresh orange or vit. C from a pill, a vitamin is a vitamin no matter what form you consume it in.

NG, thanks for the reply. You may be right, but I often hear people say that the body does not absorb vitamins from a pill as well as if it came from real food. They would say that it is better to get your vitamin C from eating oranges than from taking a pill, as your body would assimilate the vitamin C better. Similarly, it may be better to drink the tea rather than pop a pill. Moreover, some people say that herbs, minerals, etc. are better assimilated by the body if taken in a liquid form rather than from a pill (i.e gingko biloba is supposed to better as liquid than as a pill, at least according to some accupuncturists I used to know).

Some people say lots of things. If you want a real answer, use your GOOGLE and look for research. For example, find out where someone has real data that male pattern baldness will respond to green tea in any form and if so, how much? A gram, 50 grams etc.
Hint-Tons of male pattern baldness in Asia, the area where Green Tea is used more than anywhere in world. Then again, no data to suport that observation either.

That's good advice Bruce Lee. My curiosity about green tea actually has more to do with it's anti-oxident power for overall health benefits rather than hair loss specifically, although of course I'm curious about how good it is for the hair as well. I drink it more for the anti-oxidents, and wonder if a pill is as good as drinking it in that respect. Maybe this a question that can be addressed on some health or vitamin related message board.
By the way Bruce Lee, I just got my Revivogen in the mail today. I know you are not too high on it, at least compared to the proven cocktail of the big 3, but I have a good feeling about it. Maybe attitude is part of the equation? Anyway, I'll keep people updated peridodically for those interested.

I used to do the herb capsules for the same reason and for various reasons. think the caps are the way to go. Best of luck on that and the Revivigen.

Re: Derek
I'm sure you are right but I think that attitude in general might be a little confusing to people. Over and over the medical community has found that they have been unsuccessful in isolating the beneficial compounds in food. Usually a particular compound or extract is attributed a health benefit but once isolated the benefit is lost, either because there was synergy with other components of the food or the benefit came from a minority isomer of the compound rather than the majority isomer which was isolated.
Case and point is Vitamin E,
http://www.gnc.com/health_notes/Supp/Vitamin_E.htm
The dl-alpha tocopherol in synthetic Vitamin E supplements has failed to exhibit any health benefit at all in scientific testing and is at the least most probably worthless. Emerging reseach seems to suggest that alpha tocopherol may even undo the benefits of the other natural isomers.
Almost every nutritionist or doctor will tell you that it is better to get nutrients from food than from a supplement because we just don't understand the relationships as well as some would lead us to beleive. Supplements are always the 2nd choice.
Not that this has anything to do with green tea or grape seed, if the extracts work then they work, no arguing with success.
