Hi,
Let's break up the images to find a solution for each case. For complex grooms you may need to create several hair objects for different parts of the hair. For example, the curls on the Asion woman can be done in two ways: Using a curl modifier or using the twist parameters in the Clump modifier. in general I think your project is going to need lots of experimentation and be pretty familiar with Ox.
Let's start with the first image from left to right. Please find a highger resolution reference and break the reference into sections so we can approach each part of the hair individually with different techniques.
