Before I send you a quote please try this: Get a pair of really strong leather gloves (biker gloves, welder groves, even latex coated gardening gloves will do) and try to braid hair. Reason for me asking is that you don't have haptic feedback from the hand. If you need haptic feedback it's a different story.
It's easy
Braiding hair even with gloves is simple
As long as it can hold a comb
I never manged to do that (braiding, so that it looks nice, even without gloves).
So no feedback, thumb with 2 DOF, all others with 1 DOF (simillar to the video)? Forefinger and middlefinger are sometimes realised as 2 DOF - in case you need more precision (the formost section is never implemented as a seperate DOF).
Huh?
If you can make the arms.
Braiding is simple
There is a reason why technology is able to progress so fast when it comes to mathematical calculations, Writing, drawing with advent of Gen AI.
Yet it took years & billions of dollars for them to get a 2 legged robot walking like humans.
Walking & handling things are much more complex problems than we anticipate.
The video you have shown is one of the most basic example of Robotic handling of objects.
But the problem you state requires much more work than that.
It is quite obvious you have an end goal in mind without proper understanding of the task and hence the underestimation & oversimplification.
But the task would entail:
a) Basic physical modelling of the hand.
b) Inverse kinematics to workout the mechanism.
c) CAD to visualize the complete 3D model of the hand
d) Electrical & Electronic subsystem design.
e) Planning & control of the motion.
That should maybe lead you to a level of working prototype from where you can improve upon.
Now the question is, do you acknowledge these steps are required here?
I agree it is challenging but it is possible
And since it's worth so much it's well worth the effort
I sent you a quote, but brace yourself.
Anything you can imagine. Simpsons already did it.
Woe
I need to think about that
I miss the robotic hands 
Hi, @jameskennymatheson
Welcome to the forum.
Please answer this question;
Can you please tell us your electronics, programming, arduino, hardware experience?
Are you aware that human eyes and sense of touch are needed to do hair braiding, a relatively complicated process for a machine.
What is the advantage of having a mechanical hand copying a real hand?
If you want to braid remotely, you can still only braid one head at a time.
Do you see the missed logic in what you want to do?
If you want an AUTOMATIC braider, then this forum is out of that league.
Tom.. 
I have minor experience
Nothing of a school level
I agree this will take research so I will have to digress from this until I am have more knowledge in this area
Thank you for letting me ask this question
You mean like the YouTube
