Hi Curly_Wurly!

My hair is 3c/4a.

For at-home coloring, there are products without ammonia. I believe Clairol Natural Instincts is one of them. I have used Garnier Nutrisse in the past and it came out really nice. If you do go to a salon, ask them about the products that they use. I'm sure that you can find a salon that has safe products. I wish you the best with whatever you decide. I'm sure it will be beautiful.
