I've been coming to these forums on and off forever-- I'm 68 and have been successfully keeping most of my hair for 50 years. The key for me as the old-timers here may recognize, is to absolutely wash your hair every single day of your life and for young people twice a day. Removing that sebum is ONE key factor. "Shinny bald head" is not just a saying...it's true. Dry scalps without grease or sebum are healthy scalps. Women in general have nice dry scalps, men that are balding have greasy, sebum laden scalps. This sebum is detrimental for people WHOSE FOLLICLES ARE GENETICALLY PREDISPOSED TO REACT TO SEBUM, which mean that not everyone with a greasy scalp with lose hair, but most will. Ok, so now we get to the meat of the title of this thread. Something is very fishy in Allergan's discontinuing the clinical trials using bimatorpost to prevent or grow hair. My take is that bimatoprost can be purchased generically and lots of people are already using it off-label so it would not have made any sense for Allergan to blow 500 million in research to conclude the obvious. And the obvious in my opinion, is that it works, and it works great. I have thinning eyebrows and asked my MD to prescribe me bimatoprost as I had heard it worked for eyebrows also. Ok after three months of using it, the eyebrows have not show a great deal of improvement. A bit maybe. But get a hold of this...about 2 months ago I started also rubbing it into my scalp and the results are truly outstanding, both in terms of filling in and a lot of hair growth along the forehead hairline and temples. This is something unheard of, and without any side effects. I read about an MD here that has also used it and modest results. Well, for me it has been amazing. Maybe the washing of the sebum religiously helps, I don't know. I got mine in Canada as a generic, as I'm in Canada. I use it once in the evening and the concentration is the standard 0.003. Will it work for someone else, I don't know, but this stuff works. I won't be replying to any messages as there is nothing more to post. The cost is about $100 for a bottle (CAD$) but I make the bottle last at least 2 months. Maybe a smaller concentration is more effective than smearing a lot, who knows. Please try and come back. Regards to everyone.
