I have tried many shine serums, and I have to say that Frederic's Shine Spray is the absolute best! No more trying to rub a serum in your already styled hair!! You simply spray and go. The smell is absolutely amazing and the shine is to die for - shiny but not that oily look. The shine really accentuates the very expensive highlights in my hair (hee hee).The only downside is this product isn't as cheap as some of the other hair shine products that are out there, but hey, you get what you pay for, right? The bottle lasts a decent amount of time, and the shine lasts for hours. The best part is the product is made with natural olive oil; so it's actually good for your hair! This stuff is my new necessity!!
