Tren made my hairline recede a bit on the corners of my forehead, I know a lot of you know what I'm talking about. What do you guys do to try to prevent and reverse this? I've been reading online that rubbing castor oil and other stuff will help stimulate growth and I know a lot of guys on here use special shampoo for it so I was wondering if someone could point me in the right direction and give me a brand and place you buy it from. Thanks guys
