I'm on my third bottle, I use this daily, 2 pipettes full as I would like to thoroughly cover the scalp. After a lot of stressful life events, and insomnia, I've had a lot of hair fall and found my hair was a lot thinner. Since using this, I have SO MUCH LESS HAIR FALL it's actually insane. Everyday when I would dry my hair I would have to gather a handful of fallout. I was dropping so many hairs daily. I've just realised this fact when coming to write this review and it's blown me away. Because I haven't haven't had to pick up fall out for two months I actually forgot that it was something I had to do daily, to clean it off the bathroom floor. I've got lots of baby hairs, and as I mentioned, I'm onto my third bottle now. I use a bottle every 4 weeks, but as I said I use this daily. And I'm very happy with the results. I'm excited to see my results after another two bottles. I've already ordered another three pack which is waiting in my bathroom cupboard. It's a light consistency that doesn't weigh hair done, and smells like a delicious sweet sugary cocktail, but the scent disappears quickly. I'm sensitive to fragrance, it gives me headaches, but the smell of this serum doesn't have any adverse effects because it doesn't linger. Wish it came in a larger bottle!
