My hair is thinning on top but very thick and curly elsewhere. I am loath to cut it off so I can wear a wig but had become quite distressed about my appearance particularly in view of home working video calls where everything looks even more obvious. (I had lost my hair following chemotherapy but that experience is different as you expect it to come back.) I confess I was a bit sceptical about this product but can truly say it has made a vast difference to how I look and feel. It is very easy to use and well worth the money. I just sprinkle and go. I will definitely be buying more.
