Hello. Thank you for writing to us at healthcaremagic
Minoxidil is a hair growth promoter.
It is commonly indicated for hair loss conditions like androgenetic
alopecia,
telogen effluvium etc.
The results would vary from individual to individual, though, 10% Minoxidil is stronger as compared to 5% minoxidil.
Minoxidil is a prescription product and therefore I would suggest you to visit a
dermatologist and use it under your doctor's advice, rather than using it on a friend's advice.
Another reason for visiting a dermatologist being that besides Minoxidil, oral treatment like
Finasteride, Biotin etc are specifically indicated for hair loss conditions as well, particularly androgenetic alopecia.
Using just minoxidil may not work as well as compared to both topical and Oral treatment.
These are all prescription drugs and therefore it is important to get a correct diagnosis of your hair loss condition before trying these.
