it looks great.
If you do want to wash, some wavy people do find they prefer to, you can get sulphate free curly girl friendly shampoos.
"Please explain your method smile I've tried the curly girl method a few times but can't always find clear instructions so I just half make it up, with mixed results "
The basics of it are, wash everything that's in your hair out with a shampoo with no silicones but that does have sulphates, then use a conditioner without silicones or drying alcohols, and wash with that from then on, if you use styling products you want water soluble ones.
Don't brush it, only finger comb or use a wide tooth comb while it's covered in conditioner and don't towel dry it, use cotton and don't rub - brushing and towelling cause damage.
Oh and no heat, no straighteners, curling irons and blow dry o cool with a diffuser.
The complicated bits are styling methods, but, they're only as complicated as you want to make them tbh.
I work from home today, so it's a wash day, lol.
I've washed, put in leave in conditioner, mousse and gel (because I like them) I've plopped in a t shirt for about 40 minutes and then just left it to air dry while I got on with stuff.
Tomorrow I've not got all day for it to dry, so I'll put in the leave in conditioner, a tiny bit of water and mousse and it'll be completely dry half an hour later.
Other people have other routines though.
