i was a bit as well, but my mum has been henna'ing her hair since.... for ever, and i felt like doing something new. i am really glad i did it, its such a natural colour, most people dont really notice that i died my hair, but that tells me that its a really natural colour that suits me.
looking into it is a good idea, what colour are you thinking about going?

my hair: 3b, high porosity, high density and coarse hair (i think i finally figured that all out)
my hair loves conditioner only styling!
Oils and my own procuts are my hairs best friend
my hair goal length is bra strap length when curly.
