I'm looking for advice/experience from anyone who's used a product applied directly to hair/scalp that promotes growth, that you'd recommend.
I tried hair gummies which did cause thicker growth, but it affected it all over 
I have PCOS so already have issues with hair growing in places where it shouldn't, and am having laser done on my face, so felt I was throwing money away on treatment as the hair was growing back much quicker.
I used to live in the Caribbean and had thick long hair, since moving to the UK my hair has fallen and thinned. I'm aware that's also a side effect of PCOS, but I had PCOS in the Caribbean and much healthier-looking hair.
Any advice would be appreciated! Thanks
