I have a lot of hair and you cannot see my scalp except for the part. When I wear a ponytail (always without the part), I still have a lot of hair, very bushy. I always find it difficult to get hold of elastics (is this the correct word in English?) that are firm and stretchy enough to make the ponytail.
Just to illustrate: this was August 2012, normal hair day https://fbcdn-sphotos-e-a.akamaihd.n...63809864_n.jpg
Based on how my hair responds to emollients in my conditioner and protein in my styler, I think it is fine (whereas I really thought it was coarse). Coincidentally, I ran into my mum yesterday and she just came back from her hairdresser. She has no curl whatsoever, but she told me her hairdresser says she has fine hair and a lot of it. Her hair is even coarser than mine.
