You can download accessories bang for the hair, because as I see, the two hairs you listed are already pretty close to your need, bang is often categorized as Hat, for example:
As for the female hair, in TS4, you can easily select the Feminine tag when browsing hair to select female hair for male and vice versa, if you want the hair to permanently stay in the male section, use Sims 4 Studio, open the package and tick the Male box - apply to all swatches -save
Yep, Sims 4 Studio is a life saver if you frequently use CC, you should check out the Batch Fix; Update CAS CC for all gender too, because lots of old CC are restricted to only one gender so you just have to run S4S once and everything are fixed.
I enabled the female hair for dudes and it looks okay-ish but it has a graphics issue around the forehead. Its not there on the original Romantic Garden hair so it must be from the creator editing the mesh.
Easily covered by a hat or baby hair (if you use those)
