Caffeine and hair growth
We would need an equivalent of 50-60 cups of coffee in order to produce noticeable hair-growing results – the amount which is unsafe and dangerous for your health, and is NOT what you should do.

Because hair thinning and poor hair growth are sometimes associated with a biotin deficiency, correcting a deficiency can help restore hair growth in some people.
