You may be on to something, belladionne. Apparently L'Oréal patented a hair growth aid for men that contains grapeseed and red wine extract.
The main focus of that article was the impact of taurine (a non-essential amino acid) on patients suffering from hair loss, specifically androgenic alopecia (and that taurine in combination with other polyphenols like resveratrol [which is found in grapes and wine] significantly helped impede hair loss).
In addition to that, this little article agrees that resveratrol can aid in hair loss prevention:
http://www.buzzle.com/articles/hairloss-prevention/
"Certain hair oils and tonics containing Resveratrol can also be beneficial to some patients suffering from hair loss."
The article below briefly mentions resveratrol when studying another anti-androgenic compound to aid in hair loss prevention:
http://www.freepatentsonline.com/20040014732.html
"Popular traditional Chinese medicine utilized topical treatment of androgenic effluvium and alopecia with an extract from Polygonum cuspidatum, an asian cane which contains resveratrol. Phytoestrogens and other substances are known to interfere with androgenic receptors. (Mitchell, et al. Cancer Res. (1999) 58:5892-5."
"Various plant extracts which are useful in treating alopecia and decoctions such as birch extract, nettle extract, green tea extract, or the like, as may be conventionally employed and as may be moderated for use in conjunction with the subject compounds. The treatments may be performed concurrently, consecutively or in accordance with a predetermined regimen of particular interest is the use of resveratrol, a plant extract which can be obtained by extraction from plants such as Asian cane. Synthetic resveratrol is available from Aldrich. The plant extracts may be used in accordance with conventional applications, preferably at reduced dosage or frequency of administration."
And one more article found here:
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=15800385&query_hl=3&itool=pubmed_docsum
Parts from abstract: "Angiogenesis, the formation of new blood vessels from preexisting vascular network is a driving force of organ development in ontogeny, is necessary for ovulation and hair growth, and is prerequisite for proper wound healing...Numerous bioactive plant compounds, often referred to as nutraceuticals are recently tested for the potential clinical applications. Among the most frequently studied are resveratrol, a polyphenol present in red-wine and grape-seed, epigallocatechin-3-gallate (EGCG) from green tea and curcumin from Curcuma longa."
So even though I found one article that said it didn't work, I'm gonna have to say that there is a
possibility that this could work, although I have yet to come across articles implicating wine or resveratrol alone in aiding hair growth. Since resveratrol is found in grapes (and most wine is made from grapes), I think eating grapes or drinking grape juice would also be a good alternative to people wanting to test this out.
