Try Mane 'n Tail shampoo. It was originally developed for horses and animals. But it turned out to be good for human use as well. I use it. Friends I recommended it to were pleased as well. The shampoo helps to reduce hair loss, gives hair a nice sheen and makes it more manageable. This American product can be found at Walmart. You got to look hard to find it. It's not a high volume product and it gets tucked into a lower shelf. It cost about US$8.00 for a 355 ml bottle. If you pick it up in the pet section, yes, PET section, it costs under $10.00 for a one-litre (1000 ml) bottle. The product sold at the regular shampoo section has more scent to make it more marketable. Otherwise, it is exactly the same product as the one you find in the pet section.

I'm sure it will point you to other distributors.
You'll find lots of positive consumer feedback on the internet too.
I'm not sure if everyone who uses it will be a millionhaire. But there should be positive results for most users.
