No Serum Can Repair Split Ends
Some beauty brands sell serums and oils that “repair” split ends. But these products only provide temporary relief, if anything. According to SELF, these products glue the hair strands together to “repair” them. But the glue only lasts until your next shampoo session.
Save your money. The only way to relieve split ends is to cut them off, says hairstylist Jordan Garret. If you pull apart split ends, you could damage the rest of your hair.
