I love that this product helps with environmental pollution. Since I live in a big city I usually use face masks that combat the effects but I never thought to give my hair the same attention. Smells amazing and really works to help hair.
Doesnt make my hair greasy or weigh it down! Has a nice light scent and made a huge difference in the health of my hair even after only one use and my hair is bleached blonde!
I love these kinds of products and my trip was a great way of putting it to test. It’s a leave in serum (a little thicker than milk) that protects against heat damage. I used to leave it in my hair for a while and then style them if needed. Great if you’re using styling products or even when you’re just out in the sun. My hair felt great and less damaged. #gotitfree
