PGD2 causes hair loss according to Dr. Cotsarelis

[Thermal]

0.75 mm is a big bastard.
Does it make your scalp bloody or very red?

I use 0.5 and sometimes it hurts when I press it harder.
Anyways, I was looking into eye drops prices, and I don't know how economical it is because 10 ml costs around $10 + shipping. 10 ml wouldn't last very long.

How often and how long should one use it to see some results?
Any guesses?

There are some cheaper eye drops around in the UK which contain Sodium Cromoglicate http://www.pharmplexdirect.com/galph...n&currency=GBP

Can also get it on prescription in capsule format. http://www.pharmplexdirect.com/nalcr...n&currency=GBP
