Rogaine 5% causes hair colour to change?

[kumardarshan]

I notice some hairs to change to grey / white after applying rogaine 5% on beard hairs. The whole hair is black but  is white from the root. Is this normal or common?

I think I read something about this and that it is temporary. But I would consult with others and perhaps a physician if this is normal or if it is due to some alternative cause.

...are you sure your hair isn't turning grey from normal aging?

Rogaine is an incredibly popular and well-researched medication, used by tens of millions of men throughout the world. If greyness was a side-effect I'm pretty sure it would be really well known.

It could be due to shock loss. I jus had beard transplant and I am post shedding phase. It is not part of aging as my whole beard is black.

I’ve been using topical minoxidil again for the past three months. I have beard and scalp grafts and I haven’t noticed the beard hair (or scalp) changing color from its use. Perhaps speak with your dermatologist. All the best.
