19. THE HAIR
• It’s a protein filament grows from hair follicle in
dermis of skin.
• Keratin is the protein found in hair.
• Pigments of hair is responsible for its color.

20. ARRECTOR PILLI
MUSCLE

21. PARTS OF HAIR
IT HAS 3 PARTS
1. ROOT –PART OF HAIR ELOW THE SURFACE OF
SKIN, Widest Part--follicle
2. SHAFT- The body
3. TIP– The End Of Hair , The Narrowest
Part.

22. HAIR BULB
• Part of root
• The hair bulb is the bulb-shaped structure at the base of
the hair follicle
Each hair bulb includes:
• The area of cells that produces new hairs by mitosis is the
GERMINAL MATRIX
• PAPLLA is the area that contains many blood
vessels which supply nutrients to nourish the growing hair

23. ROOT SHEATH
Two layers :- surrounded by an outer sheath of connective tissue.
• External epithelial root sheath :- Consists of several layers of
cuboid epithelial cells visible when stained with H&E stain,
a histology stain
• Internal epithelial root sheath :- consists of three layers:
1. Henle's layer
2. Huxley's layer, and
3. Cuticle of inner sheath.

25. LAYERS OF HAIR
It has 3 layers
1. Cuticle- outer covering with over lapping
scales
2. Cortex – PROTEIN RICHED,
ARROUND THE MEDULLA HAVING
PIGMENTS (melanocytes).
3. Medulla – the central core part

26. GROWING CYCLE OF HAIR
There are cycles of hair growth & loss during which the
follicle presents different appearance
It has 3 growing stages
1. Anagen
2. Catagen
3. Telogen

27. ANAGEN
• It’s the growing phase of the follicle.
• Maximum development of hair takes place
• Mitosis occurs during this stage
• ~90 % hairs are in this stage
• Lasts for 2-6 years
• Growth 1-1.5 cm / month.
• Hair bulb is rounded, full and contains melanin

28. CATAGEN
• It’s the transition stage ~1-2 % of hairs are
at this stage
• Lasts for 1-2 weeks
• Mitosis stops hair =>growth ceases.
• Germinal matrix shrinks away from the
papilla

29. TELOGEN
• The resting stage ~8-9% of hairs
• Lasts for 3-4 weeks
• Follicles has shrunk away from the papilla
• The inferior segment of follicle is absent in this
phase and this is succeeded by the next anagen
phase.
• Hairs fall out ~50-80 hairs / day

31. • The ‘danger area of the scalp’ is the area of loose connective
tissue. As pus and blood spread easily within it, and can pass
into the cranial cavity along the emissary veins. Hence
infection can spread from the scalp to the meninges, which
could lead to meningitis.
• Scalp laceration bleeds profusely as elastic fibres of
underlying glea aponeurotica prevent initial vessel retraction.
• Hence significant blood loss which may lead to clinical
shock

32. • So it is essential to control all bleeding points before
suturing the lacerations.
• Failure to control the bleeding points can leads to
hematomas.
• Repair of scalp require full thickness tension sutures
because the glea aponeurotica will otherwise gape as
the occipital and frontal bellies contract.
• Scalp flaps can be used in craniofacial surgery for
correction of congenital deformity,

33. SCALP AVULSION
• Avulsion - body structure is forcibly detached from its
normal point of insertion
• The inner smooth surface of avulsed scalp is first placed
on a spherical vessel or container. The long hairs is then
clipped and shaving commence from front to back and
side to side .The eye brows are not shaved.

34. • After the completion of shaving the scalp is washed
thoroughly in running tap water. Then the scalp is taken off
from the container. The scalp is prepared without any hairs in
the inner part of it.
• All patients has acceptable recovery of sensation of forehead
and scalp by 6-9 months after replantation.
• There will be satisfactory hair growth

36. SEBASEOUS CYST
• Due To The Presence Of Numerous Sebaceous Gland
The Scalp Is Commonest Site Of Sebaceous Cyst.
• The Sebaceous Gland Produces The Oil Called Sebum
That Coats Our Hair And Skin.
• Cysts Can Develop If The Gland Or Its Duct, The
Passage Where Oil Is Able To Leave, Becomes
Damaged Or Blocked. This Usually Occurs Due To A
Trauma To The Area.
• Treatment:-
Surgical Removal
Of The Cyst.

37. TELOGEN EFFLUVIUM
• Thinning or shedding of hair resulting from the early
entry of hair in the telogen phase.
• Emotional or physiological stress may result in an
alteration of the normal hair cycle and cause the
disorder, with potential causes including eating
disorders, fever, childbirth, chronic illness,
major surgery, anemia, severe emotional disorder, crash
diets, hypothyroidism, and drugs
• Vitamin d ” levels may also play a role in normal hair
cycle

In Color With A Rim Darker Than The
Normal Skin.

40. DISSECTING CELLULITIS OF THE SCALP
• Pus-filled Lumps Develop On The Scalp, Resulting In
Scarring And Permanent Hair Loss Over The Area
Affected.
• Most Likely Due To Blocked And Ruptured Hair Follicles,
Resulting In Significant Inflammation And Secondary
Bacterial Infection.
Management:-
• Avoid Picking And Squeezing The Lumps As This Can
Worsen The Problem
• Avoid Oil-based Hair Products And Use An Antiseptic
Shampoo Regularly

41. • Antiseptic Washes (Eg Chlorhexidine) And
Shampoos Can Be Useful As Well As Topical
Antibiotics Such As Clindamycin Lotion.
• Doxycycline, Erythromycin Or Clindamycin.
• A Combination Of Clindamycin And Rifampicin

Required In Some Cases.
