This is an all in one type of haircare that you need in your life if you can only choose one product. It can be apply onto scalp, roots, and hair itself for instant protection and enhancement. My first impression of this serum is that it’s so beautiful, with 2 separate layers that you then shake to combine into one concentrated serum. It’s all I needed for my damage hair due to chemical treat, heat styling and color services. It works wonders on my hair type which is quite thin and fine, I believe this serum is suitable for everyone, of any hair types or hair textures. I love that not only it restores my hair barrier by repairing the problems, but further protects it from future damages. My hair is so much healthier and shinier in just a couple of use. It controls fizz incredibly well and makes my hair appear smoother. You really don’t need to use much, only maybe 2-3 times a week will get you covered. I highly recommend this if you’re seeking for an all mighty hair serum.
