TLDR Many products for hair re-growth exist, but a perfect treatment without side effects has not yet been found.
The document from June 2011 reviews the causes of hair loss and the various agents that promote hair re-growth, noting that over 40% of men over 30 and a significant number of women are affected. It discusses the hair growth cycle, factors contributing to hair loss, and lists both natural ingredients and pharmaceutical agents used as hair growth promoters, such as Swertia extract, vitamin E, Minoxidil, and Finasteride. The review also outlines methods for evaluating hair growth promoters, including tissue culture and studies on animals and human volunteers. It concludes that while many products are available, an ideal hair growth molecule has not been developed, and existing treatments like Minoxidil and Finasteride can have side effects. The document highlights the ongoing research to find new molecules for hair growth without adverse effects, using various study methods, but does not provide specific results or conclusions from these studies.
