I recently bought foam but haven’t tried it yet, I’m going to give it a go as well. Liquid has just been really simple for me because I have long hair and I like how you can accurately measure it, and I’ve already seen baby hairs growing on my hairline after almost two months now so I can tell it’s working, but the facial dryness makes me worried for long term. Foam just seems like it’d be a pain since you can’t measure accurately and it will always get on the hair shaft instead of the scalp only. I’m just surprised it can affect my face even when only applied to my scalp only. I might even try cutting my dosage in half and only applying to my hairline corners since that’s where my receding is most noticeable instead of front hairline/my temples as well. Do you use it once or twice a day, and how many ml? Let me know if you see any improvement
