Can Latisse be used for hair growth on the head?

Latisse (bimatoprost) is not very effective for scalp hair growth at the current concentration of 0.03 %. Allergan (the company which makes Latisse) is currently studying higher doses (1 and 3%). Stay tuned - these higher doses may prove beneficial for a range of indications.

Hey abbie009, Thank you for this question I am surprised not many have asked that on this platform. let me answer it for you, first a quick refresher, we use latisse for eyelashes, this is what the FDA approves it for, so if you begin to use it elsewhere, you are using off label. 
In 2011, Allergan (the company that owns latisse) did a trial where they set out to see if latisse could be used with hairloss patients. Even though some patients had thicker hair, the results were not that promising in the majority of patients. They found that the results were not better compared to other drugs on the market (ie rogaine) There are many theories as to why this doesnt help, one is that latisse helps active hair follicles that are making hair, in hair loss the follicle sort of shrinks and doesnt make hair as well or any more. 
The other issue is cost, assuming you will be using latisse on your scalp that would mean an overly expensive bill ( 150 dollars for 12 months for 5 or 10 years is a lot of money) so its best you seek a hairspecialist with an interest in hair transplantation as they can help better guide you to your best option. 
hope this helps a bit
