I don't want to start a debate. So this is the last I will say on this.
I did say in my original post or maybe the post after it, or another thread, that Type 4 hair gets straight with either relaxers or by intense heat, like a pressing comb. The blow-dryer on true type 4 hair would not be enough heat to get the hair straight or bone-straight. As far as the pressing comb, yes it can get hair straight but after awhile the hair goes back to it's original state. But 3 Type can get straight with just blow-drying or flat-iron alone, hair that's in the 3 Group and above.
As far as the relaxers and Black women. Regardless of who started it, if our hair was naturally straight then we would not continue to get them, overall I mean. Yes, some women go natural but for the most part, AA women still get relaxers, which makes their hair straight. If you have a Type 3 hair texture, your wouldn't need that chemical to straighten your hair, you could just blow dry it out.
Again, again, again. That's why I said that there needs to be more categories in both the 3 Group and 4 Group. If you have 4 hair, then you do. Looking at your hair, in the pic, I wouldn't say your hair is Type 4. I would say your in the 3 Group but maybe a 3d or 3e if there was such a category, but since there isn't, then the closest I would say would be 3c/4a? I don't know, that's just with working with the choices I have.
Again, I don't want a debate. I was just merely saying there needs to be more categories.
