What is the best hair cut or hairstyle for a limp and short hair, and The best hair color for it?

I understand you and how difficult it can be to find a new hairstyle, complexes and fears can haunt you. But I started looking online for help and information and found a post https://lovehairstyles.com/style-bob-with-bangs/ about bob with bangs. There was a lot of information on how to look after your hair, how to find a haircut and much more. 

 To look fashionable now, you need to constantly follow the trends, and of course you need to have a fashionable modern hairstyle. Can anyone advise what kind of hairstyle will look fresh now?

I recommend disconnected Short hairs and giving Highlights with looking stripe.

So it is able to show its active image .

A cut that will give more of breath and volume like fringes,layered bob,adding thick licious  curls with minimal layering and having the length fall a few inches past the shoulders makes it look thick and bouncy.

It depends on the shape of the face for hair cut..and for color it depends on skin tone

This all depends on the shape of your face and your skin color
