I'd have to vote no. It's still a rarity. Amongst women my age I do notice more fab hair which I'm happy about. It's in better condition overall, thicker, bouncier, cute styles and this applies to relaxed, natural, short, med length, and long (though much rarer).
Long hair specifically is still fairly uncommon amongst black women at least in my observations. I think it will take much more time before good hair habits permiate our community .We've been practicing the beat and tackle technique for so long that many of us still think our hair is something bad that must be gelled, greased, and hot combed into submission or relaxed every 4 weeks. The word is getting out, but it takes time.
As for weaves
Too many of us think we don't need to come the weave hair. I guess straight hair combs itself.
Weaves rarely look natural to me. No two heads of hair are the same, everyone's hair absorbs products differently, has a different natural sheen, etc. I do think track technology has jumped light years, they are so thin now, almost invisible.
