Hi Tracy I would really appreciate if you could reply to my thread regarding foam or liquid for hair longer than an inch. I had good success with liquid but encountered dandruff and itching and had to stop the treatment. I did my research and have bought the foam will the foam provide results as I got with liquid? It's been 5 weeks once daily and I sometimes think the thinning has got greater? I am even thinking of going back to the liquid. Any advice would be appreciated!
