On what site did you see that they will no longer be selling AC spray?
I personally would recommend Tricomin over Folligen. Folligen made my hair feel kind of yucky and gave my scalp and gray hairs a green tint. Tricomin is somewhat more expensive, but you could dilute it with purified water to make it last longer.
Several hundred posts about it . Also from what ive read the folligen is better for stopping and regrowing . but hte other feels better. Im not payhing the money for that. I just dont have it
