Best Answer: Yes as to creating shine and it does tame gray curly hair to a point If you have a full head of gray curly hair, I am guessing it will manage the strays without weighing the hair down (as most other hair serums do). I only have some gray hair, the remainder is blonde (but course). This is the only hair serum I use because it doesn't smell like a flowerbomb and because it doesn't give me greasy hair. I have to use more than the recommended amount though. I know my reply doesn't completely answer your question, sorry! Eventually, I will have a full head of gray hair; I'm just not old enough yet. Good luck. .
