Hello
Let me explain you that , what is the reason of white hairs in young age group.
Genetics , anxiety , tension ,
sinusitis , deficiency of
calcium pantothenate ,
zinc oxide , biotin , apra amino benzoic acid , dandruff , fungus infection , certain skin disorder ETC.
However there are so many other diseases which causes whiteness of hairs .
In your case may be anxiety or stress or tension or dandruff.
I usually prescribe a solution for local use containing MINOXIDIL, TRETINOIN, AZELAIC ACID .
For oral use I advise my patient to take a combination of biotin, calcium pantothenate , zinc oxide , para-aminobenzoic acid, niacinamide.
Since these drugs are a prescription medicine , so
consult a dermatologist and get his prescription.
For local use for hair use
KETOCONAZOLE SHAMPOO .
I also advise my patient to use permethrine soap for hairs wash.
Hope these information will be helpful for you.
Good luck.
