I feel like this helped strengthen my hair some what. But was surprised it was used up in less then four weeks, I may have used a bit too much in the beginning as I had trouble applying directly to my scalp, and I need to use it on my whole scalp.
As a suggestion, instead of a dropper maybe a long thin tip where you can apply directly to the scalp or something like it as I found it hard trying to apply to my whole scalp without using too much.
Considering in purchasing a second bottle to see if it'll help grow new hair and thicken, strengthen and lengthen my hair as they are my hair goals.
