I used it once per day and that is when things got worse. Twice per day, my hair looked better. If you are going to start, you need to use it twice per day for maximum results and then you can go to once per day for maintaining. The foam is not too expensive and it goes on nicely. It even thickens the hair cosmetically like hair mousse products. The smell can be quite strong but you get used to it. However, with your hair length its sort of a challenge to apply the foam but I just spread my hair apart and apply it on the scalp the best I can. However using the liquid minoxidil like Lee's is easier with the dropper. Most of the success stories are with minoxidil twice daily not once per day. Harry(H/B), I remember, would always recommend it twice per day and to stick with your treatments like a good soldier. From your picture, your hairline looks diffuse with those baby hairs. Is that true? My hairline is diffuse with all these baby hairs that are starting to grow out. It looks like I had a hair transplant in a sense.
