It has really helped me with Seborrhea, which I believe anyone who knows what it is finds very tiring. I had tried corticosteroids, various medications, creams, ointments, and even different formulations for psoriasis; everything helped, but the results lasted for a week, while with the lotion, I have been using it for over a year and haven't had any outbreaks since. However, in the beginning, I used it every day for at least the first three months to see significant results, and after that, I used it once a week and then took a long break of four months without any outbreaks. Now I am in the fifth month and have started to show very slight signs again, so I will use it again. In combination with the shampoo, I haven't stopped using the shampoo at all. The only downside is that it is quite expensive, but it's worth it for the results it has provided me. Another downside is that the bottle is glass, and the third bottle I bought broke as soon as I got it. Also, the nozzle is not very convenient; I used another pharmacy bottle with a tip to help me apply it correctly and prevent all the liquid from spilling onto my hair
