Just how gullible do some companies think people are?
My e-mails were full of ads this morning re- a shampoo that that restores hair growth, make your hair more healthier and alive after using it.
To that I say Absolute, Unmitigated, Bullshit in extremis because it IS a medical FACT that your hair, just like your finger and toe nails is,

1. made from the exact same stuff, Keratin, and is completely DEAD and lifeless from the moment it emerges from the hair follicle or the nail cuticle,
2. your hair has absolutely NO blood supply, nerves, etc, EXCEPT within the hair follicle itself, otherwise, every time you cut your hair, shave or trim your nails you would be in extreme pain times a thousand or more as every hair on your head/body was sliced by the scissors, etc, etc.
   All these 'wonder' chemicals they put into shampoos do ABSOLUTELY nothing except add a very false shine to your hair, give you the false impression that your very dead hair is now alive and well AND, most of ALL, add to the profits made by these companies who ARE, literally, scamming you out of your money.
   So please think twice BEFORE you fall their scams, save your money, just plain soap and water is just as good as ANY shampoo and costs you far less as well.
