Stretch mark oil/ cream recommendations?

hi ! I'm currently using a china well known brand for stretch mark oil and the lotion . cheap and good . feels equally as effective as the well known brand . for hair tonic I had very bad hair fall and when I started on this tonic not even half bottle Ald can see huge diff from dropping maybe a whole hand of hair to afew strands only. the hair tonic is by grafen, the green bottle one .
