am unsure about the curling part, but you might wanna try the brand rene furterer for dandruff. i accompanied my colleague to collect 3 sets (for hair loss and oily scalp) that she ordered from this seller in sgbrides yesterday morning, there were a few users who bought a few sets for dandruff, hair loss, oily scalp, sensitive scalp, etc and all were singing praise.
my eyes almost dropped when i saw a lady who bought a total of 17 sets as Christmas gifts for family and friends. my sister In law and 2 colleagues tried this brand for their post pregnancy hair loss and were impressed that it helped.
this brand is available @ watsons, guardians, metro, OG (i think), robinsons, etc.. if you can wait, OG, metro, robinsons sometimes have 20% and you can lug some home. according to my colleague, the sgbrides seller is the cheapest she have seen, but her stocks are kinda limited and gotta wait for 1-3 weeks if she doesn't have stocks on hand.
