Hello sir/madame! I have a cousin and he is about 20 years old and his facial hair growth is very low. The only visible growth is under chin and that too is very scarce. The sideburns are only upto 1-2 cm below ear. This makes him uncomfortable among others as at this age, his friends have dense haired moustache and beard. Suggest him some hone remedies or any medical attention he needs. Thank you!
