I have used this, which is better than many things I have used before, and I have been using it all the time, so don't worry about any side effects. I was extremely cautious when I used this at that time. There are too many liars now, and the ingredients in this one are quite healthy. I have seborrheic alopecia for a year or two. I felt very hot and warm when I first started using this. I feel refreshed and relaxed after using it, and I don't feel as oily as before. I haven't lost much hair, but my hair is sparse and I want to keep it. I have used this for about three months. My wife said I touched a little hair, which is true. You can see it when you want to grow your hair. Wouldn't it be easier not to use this? You can have a look. It seems that I stopped using it for almost half a year, and my hair is much more than before.
