Please help me with gray hair shampoo recommendations.

I have a blind date scheduled for next week.

It’s my first in three years, so I’m excited, but when I look in the mirror, my hair is a mess.

The area near my part is all white and sticking out, so I feel like I’ll ruin my first impression if I go out with this hair.

So, I’m posting this to ask for gray hair shampoo recommendations.

I really can't use regular hair dye.

After I dyed my hair last time, the red marks on my forehead and next to my ears didn't go away for several days.

I’m worried about what will happen again before my blind date.

I looked up gray hair shampoo recommendations, but there are so many different products that I don't know which one to choose.

Some say it doesn't lather, and others say the color doesn't take.

What criteria should I use to get a gray hair shampoo recommendation?

Both coverage and longevity are important, but it also needs to be gentle on the scalp. My gray hairs are concentrated in my bangs and side hair, so they're all visible when the wind blows.

My blind date is coming up soon, so please let me know if you have any recommendations for a good gray hair shampoo.

I really want to meet a good person this time!
