I have golden hair and I want to tone them down somehow to get the perfect blonde hair color. I am 19 years old, and I donât mean to look older than my age. However, people think I am in my 20âs and I believe it is just because of my hair color. Therefore, I intend to undertone my golden hair, without really coloring them up completely, as I wonât like it either! I would like to seek an expertâs guidance to neutralize the golden color of my hair, but without turning it into a messy yellow color, unlike one of my friendâs, who ended up with brassy yellow color while camouflaging her gold undertones. Please assist me suitably. Thanks.
