so yeah, the question asks it all.
I want a new haircut and like, i have pretty thin hair.

so if i get layers or something, it's gonna be like i have no hair or something ? idk that's what is in my mind.

yups, so i wanted to know which hair thickening shampoo/conditioner i can use and which ones that won't damage my hair

I have thin, long, straight, and silky hair, i don't want to make it dry and what not .
i also have Gatsby moving rubber.

well yeah it's for guys, but i still use it, it's pretty good, I also have ProStyle
