I have a lot of hair so every hair dresser tells me, its dry and curly and yes thick.I have Venus conjunct mars in leo in the 10th..
I wouldn't say my hair is abnormally warm nor does it feel heavy but I often cut it in layers to decrease how much hair I have and it's volume.
I never have the patience to let it grow out too much so it's usually by my shoulders..
I have never had very long hair, it would be too much of a pain to manage and I am not up for that..
Jupiter conjunct Uranus in the first is probably why I don't let it grow out too much..it starts feeling like too much trouble when it gets too long.
