THE INTEGUMENTARY SYSTEM
Dr Mahmoud Said Habib
The integument as an organ,
and is an alternative name for skin.
The integumentary system includes
the skinand the skin derivatives
hair, nails, and glands.

STRUCTURE OF SKIN
Understanding how the skin can function in these many
ways starts with understanding the structure of the 3
layers of skin
TheEpidermis
Epithelial tissue
Dermis
Dense connective tissue proper –irregular
Hypodermis
Subcutaneous tissue-loose connective tissue proper and
adipose tissue

subcutaneouslayer
04-Jul-23 Dr Mahmoud Said Habib 8

•The outermostlayer is called the epidermis. It is built of multiple
cellular layers. The lower parts of the epidermis contain
keratinocytes (the principal cells that build the epidermis) and
pigment cells, melanocyte, whichare responsible for the production
of the brownpigmentknown as melanin.
04-Jul-23 Dr Mahmoud Said Habib 9

The Epidermis
STRATUM CORNEUM
STRATUM LUCIDIUM
GRANULAR LAYER
SPINEY LAYER
BASAL LAYER
•14 layers (depth of a human hair)
•Corneocytes and Lipids
•Forms Barrier
•3-5 layers
•Callusing (palms/soles)
•4-5 layers
•Lipid granules & Langerhans cells
•Several layers
•Lipid granules & Langerhans cells
•Has “spines” for cellular adhesion
•Early keratin production site
•1 layer
•Produces keratinocytes
•Melanocytes
04-Jul-23 Dr Mahmoud Said Habib 10

•The outer cell layers of the epidermis
undergo a constantturn-over. As the
cellsmoveto the upper layers, they die
and fill up with a protein called keratin.
The spaces between the dead cells are
filled up with a special lipid "cement".
•In a skin that is not prone to any
problems, these outer layers are
protected with a special water-lipid
coating,and dead, keratinized cells
peel off in a regular manner to make
space for the next generations of cells.

•Underthe epidermislies the secondlayer called the dermis. This is
the layer containing bloodvesselsand nerveendings. It is in the
dermis that special cells called fibroblastsproduce collagen–a
protein responsible for skin elasticity.
Skin Structure:
Dermis
04-Jul-23 Dr Mahmoud Said Habib 16

PAPILLARY
RECTICULAR
•Composed of collagen Type 1 (80% in skin) and elastin
•High tensile strength “snap back”
•Locale for sagging
•Composed of thinner, more elastic, more densely
packed Collagen Type III
•Gives skin shape
•Locale for wrinkles
COLLAGENS are fibrous, structural proteins produced by FIBROBLASTS and made
up of amino acids proline and lysine.
There are over 14 types of COLLAGEN in the human body.

Statistics
•Statistics show that 40 to 50% of men and
womenworldwide will suffer from hair
lossby the time they reach 60, and
regional experts emphasize the need to
take both preventive and remedial
measuresto combat this problem among
millions of people in the Middle East.

HAIR
•Fastest growing tissue in the body,
secondonly to bonemarrow.
•The average scalphas 100,000hairs.
•100hairsper day are lost normally from
the scalp.
04-Jul-23 Dr Mahmoud Said Habib 34

HAIR
•Hair, like epidermal horns, is derived from skin cells and is nourishedby
the capillariesof the hair follicle.
•Arteries and veins circulate into the dermis and branch into smaller
capillaries at the hair follicles, the hair papillae, and glands Transports

•Growth
•Reproduction
•Tissue repair

HAIR
•Found alloverbodyexceptpalms of hands and soles of feet
•Most is invisible to naked eye
•Denseron head and limbs, after puberty in groin area and axillae
(armpits)
•Hairgrowthinfluencedby hormonesand geneticinheritance
Dr Mahmoud Said Habib 04-Jul-23 36

HAIR
•Hair is made up of a mixture of a proteincalled keratin andwater.
•The thicknessof the hair varies according to the place and is thicker in
the mustache.
•The growthrateis about 0.2-0.4 mm per day, 6-12 mm per month, or 7-
14 cm per year
•Growth rate varies according to race
Dr Mahmoud Said Habib 04-Jul-23 37

HAIR
•Hair type
•Normal hair: It is the middle between oily hair and dry hair, so it does
not show a lot of fat and it does not appear dryness clearly, that is, it is
neither dry nor greasy.
•Greasy hair: it is the hair in which oil appears or it loses its style quickly.
•Dry hair: it is hair that is exposed to dryness after washing and that it
loses its luster at the same time.
•Mixed hair: It is hair characterized by excess fat in the scalp and less fat
on the ends, meaning greasy from the top and dry from the bottom,
and this is the most difficult type of hair and needs great care.

All the germinate activity here.
•The matrixor the papilla:
•the vital zone at the base of the bulb.
•rich in blood vessels that bring oxygen and nourishment
to the bulb, reproduces the germinal cells
•The sebaceous gland:
•it produces sebum that nourishes and lubricates the
scales to give shine and elasticity to hair..
•The pilo-erector muscle:
•At the side of the sebaceous gland, it has the function of
emptying it, by means of compression.

hair shaft (stem)
Dr Mahmoud Said Habib
olong, thin cylinder shape formed by
overlapping cells
omade up of three layers:
oCuticle
oCortex
oMedulla
04-Jul-23 43

1-Cuticle
Dr Mahmoud Said Habib
Cuticle
•The cuticle is the outsideof the hair shaft.
•It is made up of overlapping, transparent scaleswhich protect the
cortex.
•It is made of HardKeratin& is usually 7 -10 layers thick.
•The cuticle determines porosityof hair
•creates shine, smooth silky feel
04-Jul-23 44

1-Cuticle
Dr Mahmoud Said Habib
•hair’s primary defense against damage
•The hair has only one cuticle layer
•Swelling the hair: raises the cuticle layer opens the space
between the scales allows liquids to penetrate
•Hair color, permanent waving solutions, and chemical hair
relaxers must have an alkaline(base) pH to penetrate the
cuticle layer
04-Jul-23 45

2.The Cortex
•The Cortexis the largestand most
importantlayer and is made of hard
keratin
•Approximately 80%of hairstotal mass
•Determines the textureand elasticity
of the hair and natural color
04-Jul-23 Dr Mahmoud Said Habib 46

2.The Cortex
•Peptide, sulphur, hydrogenand ionic
bonds found here –these bonds allow
us to temporarilyor permanently
changethe shapeof the hair.
•Cortex-is the middle layer of the hair
consists of fibrous protein, melanin
pigment
04-Jul-23 Dr Mahmoud Said Habib 47

3. Medulla
•The medulla is found in the centerof the hair shaft.
•Notevery hair has a medulla, it may be continuousor broken
along the length of the hair shaft.
•The medulla is made of Soft Keratin and sometimes it may
contain melanin.
04-Jul-23 Dr Mahmoud Said Habib 48

HAIR TYPES
Vellusor lanugo hair:
•Short
•fine
•Not pigmented
•Almost never has a medulla
•Found on infants On adults:
•Forehead ,eyelids ,bald scalp
•Nearly all other areas Except:

What causes hair shaft defects?
Hair shaft defects may be due to external injury or genetic abnormality.
•External injury to hair shaft.
•Repeated physical injury is the commonest cause of increased hair
fragility. This may be due to:
•Excessive grooming
•Tractionfrom braiding or tight pony tail
•Heatfrom a hair dryer
•Chemicalinjury may be caused by:
•Perminglotions
•Straighteners
•Dyes
•Weathering: Sun, Wind, Swimming,
Washing, Friction, Excessive hair

Split ends
04-Jul-23 Dr Mahmoud Said Habib 62

Heat is a great enemy to hair .
•Hair dryers applied the dryer must always be used with great care and at a
moderate setting
•Bubble hair is characterized by hair shafts with large “bubbles” within them. These thin
the hair cortex and breakthe hair shaft.
There may be a geneticpredisposition to bubble hair. However presentation is often
precipitated by externalinjurysuch as use of a hairdryer, physicalor chemicalhair
straighteningor curlingirons. –
treatment: trimming the affected hair
•on wet hair at high temperatures may also
provoke the well known phenomenon of
Bubble hair
04-Jul-23 Dr Mahmoud Said Habib 63

How to Prevent Split Ends
not wash the hair with shampoomore than 2-3 times
a week, as shampoo dries your hair out.
Use conditionersand moisturizers
Do not brush wet hair.
Hair is more vulnerable to splitting when it is wet.
Instead of a round brush, use a flat paddle brush with
wide tooth for everyday styling.
04-Jul-23 Dr Mahmoud Said Habib 64

How to Prevent Split Ends
apply a leave-in conditioner for dry hair .
Use film forming products
Use products with sun protector to protect
against sun and heat
Use nutritional products with amino acids , fatty
acids, minerals , sebum like action ,
04-Jul-23 Dr Mahmoud Said Habib 65

Modern conditioners are designed to provide one or more of the following functions:
• provide ease of wet and dry combing
• smooth, seal and realign damaged areas of the hair shaft
• minimize porosity
• impart sheen and a silken feel to the hair
• provide someprotectionagainst thermaland mechanicaldamage
• moisturize
• addvolumeand body

•The fallen hair is in telogenphase
•TelogenEffluvium
Sudden stress relate hairs loss which appears as thinning throughout the
whole scalp can be caused by:
•Child Birth
•Pregnancy Termination’s
•Birth Control Pills
•Dieting Drug

•Severe Emotional Stress
•Thyroid Gland Malfunction
•Hypothyroidism ---
•Hyperthyroidism
•Diabetes
•SLE
04-Jul-23 Dr Mahmoud Said Habib 70

Hair shedding
•Anageneffluvium
•The hair falls in anagenphase
•A diffusehair loss like telogeneffluvium, butit develops much more
quicklyand cancause individuals to losealltheir hair
•Mainly due to anticancermedications
04-Jul-23 Dr Mahmoud Said Habib 71

Hair shedding
•Anageneffluvium
•In AnagenEffluvium the hair does not enter a resting stage as is does
with TelogenEffluvium. The hair loss is usually suddenoccurring 1 to
3 weeks after expose to the chemicalsor radiationhas occurred.
Cancer treatments such as Chemotherapy and Radiation Treatments
are the most common causes of AnagenEffluvium. However exposure
to toxic chemicals such as Thallium and Arsenic may also produce a
sudden loss of hair.
04-Jul-23 Dr Mahmoud Said Habib 73

Hair shedding
•Anageneffluvium
•Chemotherapyis used in the treatment of cancer to destroythe
cancercellswhich divide rapidly within the body. One side effect of
this cancer treatment however is that it can alsostopthe growthof
the hairand may cause the shedding of hair. In some cases up to 90%
of the hair may be affected and often the remaining 10% was already
in the resting phase before the treatment was started. Some hair
follicles do not shed the hair but produce a narrower weaker hair
which breaks off easily.
04-Jul-23 Dr Mahmoud Said Habib 74

Cold therapy involves covering the
scalp with ice packs or using a special
hood filled with cold water while
giving anti-cancer drugs
04-Jul-23 Dr Mahmoud Said Habib 76

Hair thinning
•More visible scalp
•Mainly due to Androgenic
alopecia
•Due to the effect of 5α-DHT
04-Jul-23 Dr Mahmoud Said Habib 77

Effect of DHT
=Dihydrotestosterone
04-Jul-23 Dr Mahmoud Said Habib 78

Androgeneticalopecia
•Hair loss that results from a genetic predisposition that makes follicles
sensitive to the effects of DHT.
•It is the mostcommonformof hairlossand can also affect women.
•In malepatternbalding there is a gradual reduction in the duration of
anagenand a prolongation of the latent period of the hair cycle and hair
follicles also become miniaturized.
•There is some controversy over whether femaleandrogeneticalopecia is
the same entity as male balding. Nevertheless, the follicular changes are
very similar if not identical.
04-Jul-23 Dr Mahmoud Said Habib 79

Hair thinning
•Male pattern baldness is caused by a genetic sensitivity of hair follicles to
DHT, which causes them to shrink when exposed to it. This shortens their
lifespan and prevents them from producing hair normally.[2]
•Menwith androgenicalopecia typically have higher levels of 5-alpha-
reductase, lower levels of total testosterone, higher levels of
unbound/free testosterone, and higher levels of total free androgens
including DHT.[9][10]
04-Jul-23 Dr Mahmoud Said Habib 81

Hair thinning
Treatments include:
•Finasteride, the recommended first-line treatment
•Dutasterideand Ketoconazoleare also 5-alpha reductaseinhibitors, but
as of 2010, have not been FDA-approved as hair loss treatments
•Minoxidil, the recommended second-line treatment[18]
•LLLT, or Low Level Laser Therapy
•Topical Caffeine[19]

Androgenic alopecia
Hamilton scale
04-Jul-23 83

Hamilton scale
•Stage 2
•minimal receding hairline in the front or the side of scalp.
•Stage 3
•Same receding pattern as Stage 2 but it gets deeper to the back.
•Stage 4
•the frontal region almost reaches to the top (vertex) of head.
04-Jul-23 Dr Mahmoud Said Habib 84

Hamilton scale
•Stage 5
•The balding now reaches to the vertex of your scalp and frontal
region is gone.
•Stage 6
•At this point, there won't be any difference from Vertex and
Anterior thinning. Whole frontal and top part of head is a goner
•Stage 7
•Now hair has totally receded all the way back to the base of head
and just slightly above ears.
04-Jul-23 Dr Mahmoud Said Habib 85

Dr Mahmoud Said Habib
Androgenic alopecia
Ludwig scale
04-Jul-23 86

Ludwig scale
•Scale 1
•Stage 1 represents the earlybeginningsof Female Pattern
Baldness where the diffusethinningbegins all over the scalp. In
this stage, it's hard to notice any big difference or signs of
baldness.
•Scale 2
•Female losses over half of her hair. The thinning at parting are
pretty obvious and overall hair appearance might start to look
fragile and thin.
04-Jul-23 Dr Mahmoud Said Habib 87

Ludwig scale
•Scale 3
•Hair loss is pretty obvious and you can easily see through scalp. At
the very moment, at least 60-70% of hair on top of head has
already thinned out and it's very hard to cover the baldness at any
angle.
•Scale 4 (Advanced Stage)
•Getting hair back or making hair loss less obvious is pretty much
useless with medications now. By now, hair loss has reached the
advanced stage where you will see more scalp than hair.
