For starters, we shall discuss the non balding Asian/ Caucasian male face (at 30 to 35 years age).

There are 3 points, I would like you to concentrate on

A - the centre lowermost point of the hairline
B - also called the temple angle (the point where the front and sides meet)
C - the temple point (self explanatory term - the pointed tip of hair seen in the profile view).

The middle half of the hairline (in most adult males), runs parallel to the middle half of the eyebrow.

Look at any face/picture. Draw an imaginary line along the middle half of the hairline outwards (line 1).
Now draw another imaginary line over the mid half of the eyebrow and carry it outwards (line 2).

Non balding adult male - Line 1 and line 2 run parallel to each other.

When line 1 and line 2 diverge, that becomes a mature hairline.

Line 1 and 2 converge in feminine or teenage hairlines.

Thus, when you LOOK, you are now looking at the parallel configuration of the mid half of the hairline and the mid half of the eyebrow.

Let us go back to the original 3 points - A, B and C.

Hair may recede from one or all of the 3 points, exposing more scalp skin.

The more skin that becomes visible above the eyebrows, the more bald the look.
Few examples

Important - Each of the 3 points are equally important.
The following is a simplified version to help easy understanding
Person 1 : Point B may recede 3cms with minimal recession of points A and C.
Person 2 : Points A, B and C may all recede 1 cm.

The brain percieves an equal increase of visible scalp skin above the eyebrows. Thus, both the people look equally bald on a first glance.
This is an important concept to understand before you start designing new hairlines.

Now in simple to understand examples below, person 1 looks much more bald then the person 2.

When recreating a non balding hairline, each of the 3 points need to be restored. If, for example, point A and B are restored, but C is not, an element of baldness will still be percieved.

Similarly, restoring the point A, but not B will create the hairline with deep temporal recessions.

In the next step, we will learn how to determine points A, B and C.

Point A - the centre lowermost point of the hairline. Many among you may be aware of this formula, but I will repeat for benefit of others.

Measure the length, in cms, from the lowermost tip of the chin, to the point of intersection of the eyebrows (Glabella - Glabella - Wikipedia ). Let this length be Q.

Divide the length Q by 2.
Now measure from the glabella upwards.
The point A is located above the glabella at Q/2.

This is the lowermost location of the centre of the hairline.

Note : your hairline in teenage maybe lower then this.

» The point C is the “temple point”. Its usually preserved in a rudimentary
» form in most patients suffering hairloss.
»
» Point B - The lowermost point B is located at the intersection of
» 1. A line drawn, through point A, parallel to the mid half of the
» eyebrow, and,
» 2. A vertical line drawn through point C.
»
»
» For a non balding hairline, restoration of point B is as important as the
» other two points.

So Dr. I understand how you calculated A and B, but how to you calculate where C is? I know you said that its lower leg should run almost parallel to the outer eyebrow, but what about how far out it extends?

I am not sure that I agree with the general approach that you are taking. My impression is that the various point for any individual are dictated by the curvature of the forehaed in other words the change in angle from vertical forhead through to horizontal. Where the hairline is at the point that the change begins then this is the usual type I and when the angle is more than 30o from vertical where the hairline begins then the look is of hair loss.A simialr rule can be made for the temple points ???

Dear Marco,
Can you explain your point with a picture or diagram? It will be easier for me to understand.

Are you referring to the different skull shapes e.g.,

Those with vertical forehead merging fast into a very flattish top/vertex

Those where the forehead rounds from just above the eyebrows all the way to the top.
