Welcome to Healthcaremagic.
Thanks for your query.
I have gone through your query and understand your concern.Vitiligo
is a depigmentation
patches in the skin and mucosa.
It is associated usually associated with grey hair.
Vitiligo can be treated by application of steroid
But there is no cure for Vitiligo.
Because there is the complete absence of melanocytes( Melanin
producing cells) in the areas of vitiligo.
You have do investigation for autoimmune diseases like vitamin b 12 deficency or thyroid
Recent treatment that can cure both gray hair and vitiligo is "--a proprietary treatment developed by the researchers described as a topical, ultraviolet B-activated -- sunlight -- compound PC-KUS, a modified pseudocatalase."
Try to find the PC- KUS. but still it is under research.
Hope this helps.
Please reply for further queries.
Wishing you good health.
