You can only see my thinning in bright light too. Try this:
Eat 3 Granny smith or Red Delious apples a day and a few handful of Pumpkin seeds. These 2 apples have a large amount of procyanidin, even more than wine and tests have shown it to be more effective for hair growth than minoxidil. Just google procyanidin and hair loss. Google the same for Pumpkin seeds, they have been shown to reduce DHT in the body (not sure of the scalp)
These two things MAY help but I doubt it. Anyways, I am going to add the above to things in my life and see if it helps. Also there is a person here claiming that his friend used shampoo containing keto and Aloe Vera to regrow his hair. Not sure if thats true but try that also. I am going to use Aloe Vera in my regimen.
By the way, you will likely see people here soon saying the above information is rubbish and will not work. Just do the research and make your own mind up.
