This size is more affordable than the bigger bottles so I decided to go with this as my first time ordering it. It is true about the smell not being very good, but after a while you get used to it. I bought this product for my hair. After some research, I decided to use this once a week. I start off spraying my roots, down to the ends, and then massage my scalp for about 15 minutes. I then place a plastic bag over my hair for 3 hours and shower normally afterwards.
After just TWO weeks my hair is growing faster than usual (I dyed my hair a few weeks before starting to use this, so it's easier to tell by the roots how much my hair has grown). My hair doesn't frizz as much when I don't use leave in conditioner and it feels so much healthier already. Will DEFINITELY be purchasing again.
