How to make a hat like this?

You don't want to increase on every stitch or you'll end up with a big ruffly flat thing instead of a hat.  I'd look up a basic crochet hat pattern to get an idea of how to work the increases, then work one row even in between each increase row.

If I remember from the few hats I've made, you increase the same number of stitches in each row evenly spaced until you get to the size you want.  In the example given above, you increase 6 st for each increase row, so the next increase row would be sc, 2 sc in next stitch, repeat to get 18 stitches and so on. 

I'd also recommend staggering the increases so you get a rounder shape.  Putting them in the same spot in each row tends to make more of a hexagon--at least it does for me

Yep, increasing is pretty mathematical.

Let's say you start of with 6 stitches. The next time you increase, the number of stitches will be 12.
That means you increase in every stitch all around.
For the next round, you would sc 1 stitch, then increase in the next stitch, and do that all around.
(The 1 stitch + the 2 sc in the next stitch = 3 stitches, so 6 x 3 = 18)
You'll have 18 stitches in that round.

In each round you'll have exactly 6 increases.

I hope you understood that--this is something I've figured out myself, and I'm not very good at explaining things. :/
I'll make a diagram if you'd like.

I have made hats before so I know you everytime you make a hat, each row is less increases... The first row is always 2 in each stitch, then it's every other stitch, then it's every 3rd stitch, then it's every 4th stitch until you reach between 56 - 60 stitches depending on the pattern, it will usually tell you to stop increasing once you hit that amount of stitches, and from then on out it's just one sc in every stitch...

The only reason why I asked is because I thought maybe to get the tip of the hat pointy, I'd have to increase in every stitch for a few rows and then stop increasing in every stitch...

So, I understand now... Thanks guys!
