I'm kinda doubtful about this. I mean, the shampoos mentioned may increase hair shaft diameter as much as 2% minoxidil(?), but I don't think any shampoo will regrow hair.
When I started minoxidil last February, I had to use 2% for the first couple months before I got Lee's minoxidil. I was seeing regrowth in front from the 2%. No shampoo gonna be doin' dat yo.
Ooops, I turned Rasta in that last sentence, sorry.
