Any nice undercut hairstyle or a hairstyle with short sides? 

Hey guys,

Not sure if it's the right place to ask..
But, those with/used to have slick back or undercut hairstyle who uses pomade.
Do you experience higher degree of hair fall/loss ? Advice needed - Could it be due to product ? Should i stop completely?

My story:
I used to have pretty dense but thin and straight hair.. then i started the slickback thing (comb ur hair back and all)
Somehow i felt that my hair is getting lesser and lesser. Scary shit.. now worry i will go bald.
(Then again it could be due to me started swimming on a regular basis or just merely aging)

Hair cut history: slickback (pomade, hairspray)-> undercut(pomade or gel, hairspray) -> Current: School boy (pomade or wax, hairspray)
