Hi Bhanu prakash,
is an antihypertensive medicine and in early medicine days it's hair growing potential got detected when the women taking this medicine grew excessive facial hair
. It a arteriolar dilator and when applied locally will increase blood circulation to local area- it can grow hair on your tips so beware while applying. Some part of topical medicine gets absorbed by skin and causes excessive body hair growth.
Unfortunately till date no cuch medicine is available which grows hair only on face and without side effects.
Rather get adjusted to shiny scalp
I reminds me of one of my doctor friend started having inevitable hair loss, he shave off the remaining hair, got scalp massaged and took attire with shirt/T-shirts and Tough Jeans. He became a hit in campus and young men with good hair shaved off like him.
