His beard grows on one side and not on the other; can he shave it to make them even?
Question

                What is the ruling on having a beard which grows thickly on the right side but only grows a little on the left, i.e., it is not even? I have been told it is because I am young, and if I shave it, it will grow.
Praise be to Allah.It is not permissible to 
    shave the beard or to remove any hair from it, even if that is to make it 
    grow or to even it out, because no concession to that effect has been 
    narrated, even though it happens a great deal to young men whose beards are 
    just beginning to grow. If there was any reason to make it permissible to 
    shave, there would be a concession concerning it. Allaah says 
    (interpretation of the meaning): “and your Lord is never forgetful” 
    [Maryam 19:64]. 
With regard to the 
    prohibition on shaving the beard, please see the answer to question no.

Is it permissible to take 
    medicine that will make the beard grow more quickly on the left side? That 
    depends: 
Shaykh Ibn ‘Uthaymeen (may 
    Allaah have mercy on him) was asked about taking medicine to make the beard 
    grow and to treat the unevenness that occurs in it. He replied: If there is 
    the hope that it will grow by itself, then do not try, because this is not a 
    fault, since many young men, when their beards first begin to grow, do not 
    grow beards that are even all over, so he should wait and see. 
But if there is a fault, in 
    the sense that we are aware of it and have given up hope that it will grow 
    by itself, then there is nothing wrong with treating it so that the rest 
    will grow, especially if it looks odd. 
But if it does not look 
    odd, then it is better not to treat it with anything, because I am afraid 
    that this may be a kind of hair extensions, and the Prophet  (peace and 
    blessings of Allaah be upon him) cursed the one who does hair extensions and 
    the one who asks for that to be done. End quote from Liqa’ al-Baab il-Maftooh (41/15). 
And Allaah knows best.
