Yes, although it’s expensive and hasn’t had the life changing effect on my hair that some claim (possibly because it’s best on damage from chemical treatment - my hair isn’t chemically treated so most of the damage is from brushing). It does make my hair feel smoother and maybe stronger for at least a week. I tend to leave it on for a few hours and follow up with a hair mask or strong conditioner as it can have a slightly sort of drying effect in the short term
I know some other disers have used it and may be able to comment, @dingaling has said good things about it and @tilty tried it when she was worried about her hair being damaged by dye i think
I’m not convinced by “natural” stuff personally, as natural doesn’t mean better, or even safer or more environmentally friendly, and if an ingredient works well then it’ll get used in non-“natural” products as well.
