Is there a scalp care method to soothe the itching caused by gray hair growing in?

Ah... I was trying to take a picture of my gray hair... but I can see the hair loss.

Anyway, regarding scalp care methods, what I'm curious about is...

I'm fifty now and I can't go without root touch-ups.

It feels like it hasn't even been a month and a half... but it's time to go do it again.

I'm trying my best to take good care of my scalp, but...

I'm not sure if it's like that whenever the gray hairs commonly mentioned start growing in...

There are times when my head gets really itchy.

Am I the only one?

Can gray hair be that itchy as it grows in?

If that is the case... how should I care for my scalp?

I haven't bought a scalp scrub yet...

Would that also help with the itching caused by gray hair growing in, like it did for me?
