Hello and welcome.
Thanks for your query.
I understand your frustration, and although it might be a natural process for men, it is a little early for you to be experiencing this.
The first and most important thing is to avoid using chemicals on your hair, which might even temporarily help you, but will result in accelerating the hair fall
process in the long run, it is not worth it.
In today's world, with all the progress the medical field is making, in my opinion the best option is a hair transplant
This process might take sometime, but is safe and sure. Kindly look it up and discuss the possibility with an expert.
But most importantly, be confident about yourself, its what is inside that matters more than what is outside.
