Change of shampoo needed?

so trueeee... try some hair products like molding gels or puddy for hair. goodluck.

Hello all, I am new here (just joined) and needed some help on this topic for sometime. I have been thinking about switching shampoo, for I'm currently using Garnier (2-1 anti-dandruff shampoo +conditioner). Is there a shampoo that gives a hair the kind of dried texture of but healthy look? Nothing that makes it bouncy but just lays flat. Or does it depend on one's hair? Probably it isn't a shampoo, or is it a product/treatment?

I am aiming for this kind of texture (not cut):


Where it should be possible since his hair used to be like this:

(waaay more dryer)


Any help would be appreciated
Thankyou!
