Nothing positive.
I haven't noticed a thing positive about this product. I have baby-fine hair and I have noticed that any more than 2 drops makes my hair a bit oily appearing. I used it religiously for an extended period, trying to give it a good trial. I finally threw the remainder away, as it was getting annoying having to re-wash my hair because it looked oily. My hair never showed any improvement. Perhaps it was just not made for my hair type.
