Helps with frizz
[This review was collected as part of a promotion.] I've been using the L'Oréal Professionnel Keratin Alpha Sleek Anti-Frizz Hair Serum, and it does a great job controlling frizz and adding a nice, healthy shine. My hair feels softer, smoother, and much easier to style without feeling greasy. The only downside for me is the scent—I personally didn't like it and found it a bit unpleasant. Even so, the results on my hair were good enough that I'd still consider using it.

Just a Scoch
[This review was collected as part of a promotion.] I received the Keratin Hair Serum for Shine to test out and overall I really like it! It definitely adds shine and helps smooth down my flyaways without making my hair feel crunchy or stiff. That said, a little goes a LONG way with this stuff. The first time I used it I was a little heavy handed and my hair ended up looking way more greasy than shiny 😂. After figuring out the right amount, though, I loved the results. Just a small pump worked great on my hair and left it looking smooth, healthy, and glossy. If you use it sparingly, it’s a great finishing product and makes your hair look like you just left the salon.
