Hair care I bought with my own money

Hello. My personal hair care item that I bought with my own money is the Mise-en-scène Perfect Styling Serum. I love that applying one or two drops of this serum to my hair before using a hairdryer or curling iron makes the curls last longer. It also seems to help prevent heat damage to some extent when styling. The scent is a subtle rose fragrance, and since it isn't too greasy, it is great to use in the summer.
