ANATOMY OF FEMALE HAIRLINE
1 Part line and Part Peak:
Hair from the whorl from the back of scalp flow to the forehead divert to two portion one to the left and one to the right. Produce partline and part peak.
Hair flow on scalp always have a divertion .A point of divertion see from the front look like a triangle or a radiation or a Part Peak.
An important land mark of hairline. If construction hairline without this Partline and Part Peak hairline will not look natural.
Partline normally position commonly at 1,2,3 pm. Uncommonly at midline or 12.00am
Normally have 1 partline but uncommonly double partline.
Double part line
Part peak shape look like a triangle or a radiation. Very prominent in any female hairline .Compose with only single hair unit or vellus hair.
2 MID frontal:
The 2nd most prominent part of the frontal is the mid frontal region.Mid frontal produce straight, concave,convex,round or,oval shape hairline. Super feminine have concave hairline. Because of mild mid frontal baldness.
Widow’s peak is at mid line of this mid frontal. Widow's peak can be type 1,2, 3 with or without paramedian androgenisation.
Female have more soft and smooth curvature at the temple .Shape of hairline at the temple look like S curve with full estrogen line to L shape to temporal peak .
4 Sideburn :
Compose of 1 hair curve forward or backward in front of the ear.
5 Direction of hair :
Hair flow from back of scalp forward,down ward. Common direction is downward and rightward. uncommon is upward hair.
All UPWARD HAIR
6 Skin crease or minimal tension line:
Skin crease on scalp have two component. Vertical line and horizontal line
Horizontal line across the forehead. Vertical line: Collagen fiber insertion to the midline of forehead as v-shape. So if hair grow follow this line will produce V shape hairline or Widow's peak. Hair on the hairline grow along skin crease at the intersection of this two line.
7 Vellus hair pattern on forehead:
Vellus hair Meridian:
Left side Meridian
Vellus hair is very small hair at the hairline.From the part line vellus hair flow down further.The main stream of vellus hair flow from the Part line to medial side of the same side eye brow.This mainstream of vellus hair is Meridian of vellus hair. Along side of the Meridian vellus hair divert to left and right.
Commonly the Meridian hair direction is downward and originate from left partline to medial side of left eye brow.
Uncommonly The Meridian is at the middle of forehead. Hair can flow upward or downward
Commonly vellus hair will flow down the same direction like the hair from scalp.This is parallel Meridian.
Uncommonly Meridian originate from the middle of the 2 eye brow and flow upward.This is opposite Meridian.
8 Opposite Hair :
Can happen for vellus hair flow(oppsite Meridian) and terminal hair flow. Opposite hair for terminal hair:
Because hair of direction of hair flow of the opposite and the parallel will go against each other where the flow meet will produce diamond shape intersection .
This intersection of opposite hair not only happen on the forehead but also on chest wall,nape,forearm etc.
This diamond shape intersection is the causes of variety of Widow's peak and cow's lick on the forehead.
9 Cow’s Lick:
Right temporal cow’s lick:
If the opposite meridian flow along vertial line on the right temporal region(right Meridian).Vellus hair will meet with the terminal hair at the hairline produce a cow's lick.The diamond interesection is just behind the cow'slick.
Midline cow’s lick:
If the opposite Meridian flow up along midline will produce midline cow’s lick.
10 Widow's peak:
10.1 Widow's Peak Type 1
A common widow's peak in men and women a triangular shape group of hair at the middle of forehead.The tip is round or pointed. Hair direction is downward and rightward.
Common widow's peak or Widow’s peak type 1 is not from the opposite hair but parallel hair. Hair grow on the vertical skin crease line .
10. 2. Widow's peak type 2,
This uncommon widow's peak is a group of triangular shape hair.
Hair direction can be straight upward,or oblique upward, 2 different group of hair.Tip is very point. Hair grow on the vertical skin crease line.
Opposite Meridian occured both side of midline or just on one side.Hair direction in the Widow's peak will be upward and the tip will be very point. Opposite hair can effect only left side of widow's peak. Hair in this border zone will grow upward and rightward(oblique up).
If the opposite hair flow along left Meridian. Diamond intersection will be in front of the part peak.Vellus hair will flow oblique on the hairline(perpendicular to the meridian).
Hairline hair grow on horizontal skin crease line.Opposite hair will become oblique cow's lick.
Widow's peak type 2 can subclassify to.
2.1 Bilateral of the midline
2.2 only one side of the mid line
2.3 Opposite hair on left side of widow'speak only. This is the most common of the type 2
10. 3. Widow's peak type 3:
A complete triangular shape hairline with round tip in both man and woman . Hair grow on the vertical skin crease line.
Widow's peak type 3 still can further subdivide to:
3.1 Commonly hair direction is downward and rightward.Tip is round.
3.2 Uncommonly if compose of opposite hair.Hair direction is upward .Tip is very point.
3.3 Very uncommon if opposite hair effct only the left portion of the peak.The tip can be very point
10.4 Round shape widow's peak:
Half a whorl on hairline.
If the partline and part peak is on the round frontal scalp can produce half of a whorl on hairline.
A whorl on hairline:
If a diamond shapeof opposite hair intersection on a hairline on the round surface. Will look like a circle.A circle of hair with centre from the tip of part peak .Look like a whorl from the front.
Double whorl on the hairline.
If happen in individual with double partline then will be 2 circle of hair on the hairline.
10. 5 Combination widow's peak:
If round shape widow's peak combine with opposite midline hair. The widow's peak will look like a goft ball on the pin.
What cause and modify a widow's peak:
1.Genetic ,Phenotypic frontal hair pattern .
2.Aging and degenerating factors
3. Androgenisation in male or mild androgenisation in female
10.6 Half a Widow’s peak:
A widow’s peak is modify by androgenisation but the effect can be very asymmetry or happen unilaterally produce half a Widow’s peak.
Significant of widow's peak:
1. In construction of female hairline for transgender. Generally these lady do not like to have widow's peak.They think Widow’s peak is male,more strong and aggressive look.She want somethings which is more soft smooth and sweet look.
2. In lady who already have widow's peak. Do not try to completely eliminate it.
make it smaller.
For type 1 widow's peak .It is possible to change the shape of hairline
from widow's peak to round because hair direction is the same in both
in the termainal hair zone and in the peak zone .
Type 2 have to match the hair direction.
3. In construction of hairline for baldness. Widow 's peak can give an illusion of lower hair line.??/But make sure is natural look.
4. Widow's peak is good for camouflage scar from previous surgery on forehead eg. coronal lift,scalp advancement etc.
Widow's peak Type 2 is my first choice to camouflage scar from Juri's Flap because of same hair direction. Widow's peak will make this flap look much more natural.
