For someone like me who struggles with dry scalp and dry frizzy hair I am always searching for a better solution. The Rootist BioBrew Fermented Strengthening Serum caught my attention with its stunning packaging and drew me in with unique superfood ingredients. I have very thick shoulder length hair that I color and straighten regularly. I used 3 pumps and massaged into my scalp, I love the idea of nourishing my scalp with a multivitamin of sorts and saw a noticeable difference after one use. I also applied a total of 5 pumps to the rest of my hair and found this to be a decent coverage after brushing it through. My hair feels soft and I liked that it would protect my hair from heat damage. This product definitely worked better than my regular heat protectant spray and is something I could see myself adding to my regular routine. **This review was collected as part of a promotion.
