its very affective. I have used it personally and my hair of chin and sides have decreased than before. Its second sessions.
It indeed is a good investment for all those hair issues. IV been using it and I see a visible difference just wished I came across this product a few years ago.
Recently have started using this serum and I must say im really satisfied with the results, I got visible results in the first two sessions. For sure going to be ordering my second bottle soon!
