Well our hair root is richly supplied with blood vessels but once the hair is formed and reaches the surface no nutrition reaches there in other words the hair once formed is not having life and it can not repair it self after injuries by any external agent of chemical, physical or thermal nature.
Although one must know that hair needs Protein ( Keratin) which is formed from Amino acids ( esp. L -Lysine), certain Vitamines ( Vit. A, Vit B6 B12, Biotin, Vit D and Vit E) and Minerals ( esp. Iron and Zink).
Dieting, Starving, Bariatric surgery ( for weight reduction) etc. can cause deficiency of one of these nutrients for the hair and can cause hair loss or growth problem. Although this is not common and esp. not in those who take regular balanced diet.
Deficiency should be diagnosed and can be treated by appropriate nutritional supplements. In females Iron deficiency is not uncommon due to monthly blood loss.
It takes 3-6 months before any change can be perceptible on regular treatment for deficiency correction. The miracle cures should be looked at with suspicion. There is no overnight cure.
The kind of picture that you have should be investigated for miniaturization studies and other tests to rule out Pattern Loss or other causes instead of simply taking vitamins. In fact excess of Vit A can cause other problems besides increasing your hair loss.
Hair Loss in womencan be Localized or
Generalized Hair Loss:
Localized (patchy) Hair Loss (Alopecia)
The following are the more common causes of local alopecia.
A dermatologist should be consulted if any of these conditions are suspected.
Note: the term alopecia is synonymous
with hair loss. Localized hair loss in women may be sub-divided into scarring and non-scarring types. Alopecia
areata is recognized by the sudden appearance of
discrete, round patches that are completely devoid of hair. Occasionally, the
entire scalp may be involved (alopecia totalis)
and even the entire body hair including the eyebrows and eyelashes (alopecia universalis). When localized, the
lesions respond well to injections of cortisone. Generalized alopecia is more
difficult to treat. The prognosis is better the older the age of onset.
Alopecia areata can occasionally be associated with other conditions such as
thyroid disease. (more at: http://goodbyehairloss.blogspot.com/2010/03/alopecia-areata.html) Hairstylesthat exert constant pull on the hair, such as
Dread lock; . “corn rows” or tightly woven braids produce a characteristic
pattern called “Traction
Alopecia” that can be identified by a rim of thinning or baldness
along the frontal hairline and at the temples. This is easily prevented by
changing one’s daily hair-care habits, but once the hair loss occurs, it may be
permanent. Fortunately, this condition is easily amenable to surgery ( usually
by Hair Transplant) if the cause can be eliminated. Trichotillomania
is a condition seen more commonly in young
females, where the person twists, tugs or pulls out her hair. This can be scalp
hair, eyebrows or eyelashes. The diagnosis is made by observing short, broken
hairs in the area of hair loss. The patient may deny having this habit.
Face-lift
and brow-liftprocedures can result in local hair loss in
the vicinity of the incision. This may present as hair loss along the frontal
hairline, in the temples, or adjacent to a surgical scar. If female patients do
not have genetic hair loss, and have a good donor supply, they may make
excellent candidates for a hair transplant. Tinea
Capitis
is a fungal infection of the scalp. It
presents as irregular, red and scaly patches and/or small bald patches with
broken hairs. The diagnosis is made by scraping a small piece of scale from the
scalp and obtaining a bit of hair for testing. The specimens are sent for
special fungal stains and cultures. Pseudopaladeis a non-specific scarring alopecia that
generally starts on the top of the scalp and extends into the surrounding hair
bearing areas with finger-like extensions. The areas look smooth and white due
to the scarring and loss of hair follicles. Lichen
Plano-pilaris is an
inflammatory condition of the scalp that presents with redness, scale and
localized areas of hair loss. There is a characteristic scaling at the edge of
each balding patch. Discoid
Lupus Erythematosus(DLE) is the localized form of Systemic Lupus
Erythematosus (SLE), a potentially serious autoimmune disease. The localized
form presents with red, scaly, pigmented patches of scarred skin. The localized
form of the disease is mostly a cosmetic problem, but patients must be
evaluated for the systemic disease as well with specific blood tests such as an
ANA. SLE can cause diffuse (generalized) hair loss and both the local and
systemic forms of the disease may cause sensitivity to the sun.
Triangular Alopecia, Triangular alopecia refers to a thinning or
complete patch of hair loss at the temples. The medical community does not know
the cause of triangular alopecia, but it can be treated successfully with
surgery. Triangular alopecia is permanent without treatment.
Loose anagen syndrome
Loose-anagen syndrome is a
condition easily extractable anagen hairs and is an Inherited autosomal
dominant condition seen most often in younger people that is evidenced by
excessive hair caught in hair brushes or in the bathtub drain. The condition is
caused by hair follicles that are not set firmly enough in the scalp. This
condition normally becomes less of a problem as we age.
Diffuse Hair Loss (Alopecia)
1.AGA
(Female Patterned Hair Loss, FPHL)
In case of Pattern Loss (AGA) there is usually a Family
history of Hair loss it can have Female pattern of Ludwig or Christmas Tree
type or occasionally that of Male pattern type. But females rarely have as
sever hair loss as that of males. AGA in women is not usually accompanied by
increased shedding. However, in some instances, an episode of telogen effluvium
following childbirth, major illness or other causes may uncover a latent
predisposition to AGA. Both young women and young men with AGA have higher
levels of 5 reductase and androgen receptor in
frontal hair follicles compared to occipital follicles. At the same time, young
women have much higher levels of cytochrome
p-450 aromatase in frontal follicles than men who have minimal aromatase,
and women have even higher aromatase levels in occipital follicles. The diagnosis of AGA in women is supported by Family
history, early age of onset, the pattern of increased thinning over the
frontal/parietal scalp with greater density over the occipital scalp, retention
of the frontal hairline, and the presence of miniaturized hairs. Most women
with AGA have normal menses and
pregnancies.
Common or “hereditary” baldness in women, also called
female pattern alopecia, is genetic and can come either the mother’s or
father’s side of the family. It is caused by the actions of two enzymes;
aromatase (which is found predominantly in women) and 5-a reductase (which is
found in both women and men). The action of 5-a reductase is the main cause of
androgenetic alopecia in men, as this enzyme converts the hormone testosterone
to DHT. DHT is responsible for the miniaturization (shrinking) and gradual
disappearance of affected hair follicles. Women have half the
amount of 5-a reductase compared to men, but have higher levels of the enzyme
aromatase, especially at their frontal hairline. Aromatase is responsible for
the formation of the female hormones estrone and estradiol. It also decreases
the formation of DHT. Therefore female AGA is less severe and Estrogen is a
protection against this type of loss in females* Its presence in
women may help to explain why the presentation of female hair loss is so
different than in males, particularly with respect to the preservation of the
frontal hairline. It may also explain
why women have a poor response to the drug finasteride a medication widely
used to treat hair loss in men that works by blocking the formation of DHT.
The Ludwig Classification uses three stages to describe
female pattern genetic hair loss:
Type I (mild)
Type II (moderate)
Type III (extensive)
In all three Ludwig stages, there is hair loss on the front
and top of the scalp with relative preservation of the frontal hairline. The
back and sides may or may not be involved. Regardless of the extent of hair
loss, only women with stable hair on the back and sides of the scalp are
candidates for hair transplant surgery.
Type I: Early thinning that can be easily
camouflaged with proper grooming. Type I patients have too little hair loss
to consider surgical hair restoration
Type II: Significant widening of the
midline part and noticeably decreased volume. Hair transplantation may
be indicated
if the donor area in the back and sides of the scalp is stable.
Type III: A thin, see-through look on the
top of the scalp. This is often associated with generalized thinning.
2. CTE (Chronic Telogen
Effluvium),
Women’s hair seems to be particularly sensitive to
underlying medical conditions. Since “systemic” problems often cause a diffuse
type of hair loss pattern that can be confused with genetic balding, it is
important that women with undiagnosed hair loss, be properly evaluated. Medical
conditions that produce a diffuse pattern include:
Medical conditions that can cause diffuse hair loss
in women:
Obstetric and gynecologic
conditions such as post-partum and post-menopausal states or ovarian
tumors
Iron deficiency- rather than Anemia
Thyroid disease ( both Hyper and Hypo Thyroid State can cause hair
loss and dry thin hairs-However, your head is not the only place you might lose hair due
to thyroid disease. A symptom unique to hypothroidism is
hair loss
on the outer edge of the eyebrows and a thinning or loss
of body
hair is also possible.) even the medications to treat both states can
also cause Hair loss.
*During pregnancy and in early phase of OC pills/ HRT usage female can have good growth of hairs due
to higher estrogen levels; during post partum and lactation phase, OC pills/HRT
withdrawal and menopause there is
increase loss of hair due to low estrogen levels). Higher free testosterone (PCOD)
Androgens (CAH, Adrenocortical Tumours,
Androgen Secereting tumours of Ovaries) , Progesterone (some OC pills) , Corticosteroids(cushing’s
syndrome/ stress ) and Prolactine (
Hyperprolactenemia) can also cause hair loss.
Connective tissue diseases
such as Lupus
Nutritional – crash diets, bulimia,
protein/calorie deficiency, essential fatty acid or zinc deficiency, malabsorbtion, hypervitaminosis A
Stress – surgical procedures,
general anesthesia, and severe emotional problems
A relatively large number of drugs can cause “telogen
effluvium,” a condition where hair is shifted into a resting stage and then
several months later shed. Fortunately, this shedding is reversible if the
medication is stopped, but the reaction can be confused with genetic female
hair loss if not properly diagnosed. Drugs that can cause diffuse hair
loss in women: Cardiology:
Blood thinners (anti-coagulants), such as warfarin and heparin
Blood pressure medication, particularly the b-blockers (such
as Inderal) or diuretics
Thyroid medications:
for Hypo and Hyper thyroidism
Oral contraceptive
agents, particularly those high in progestins
Orthopedics:
Medication for gout,
colchicines and alopurinol (Xyloprim)
Anti-inflammatory
drugs such as prednisone, Indomethacine, Ibugesic etc
Oncology:
Chemotherapy
Others:
Misc. – diet
pills, high doses of Vitamin A, street drugs (cocaine)
Chronic Telogen Effluvium is a condition whose diagnosis is
often missed, so it is worth mentioning briefly. Chronic TE affects women age
30-60. It starts abruptly with or without an initiating factor. Chronic TE
presents with diffuse thinning with accentuation at the temples – often more
apparent to the patient than to others. It has a long fluctuating course and
patients can lose up to 50-400 hairs/day. There is increased shedding of
telogen (club) hairs with a positive hair pull. Fortunately, the condition does
not lead to complete baldness. Chronic TE can be expected to resolve
spontaneously in 6 months to 6-7 years. When the cause of the hair loss is still uncertain, further
diagnostic information can be obtained from a scraping and culture for fungus
and a scalp biopsy (sent for regular and special tissue stains and examined
under both horizontal and vertical sections
In CTE, women in the fourth to sixth decade, with above
average hair density, describe sudden onset of marked shedding from the entire
scalp. Excess hair fall, diffuse hair loss with < 10% miniaturization, pull
test positive for bulbed hair, reduced Anagen / Telogen ratio on trichogram/
trichoscan or Biopsy. Post pregnancy and post menopausal effluvium is common. Hair pull test may
extract increased numbers of telogen hairs easily, yet scalp hair density
appears normal or minimally decreased even though the shedding may be
prolonged. Miniaturized hairs are not
seen. Horizontal sections of a scalp biopsy distinguish CTE from AGA:
the ratio of terminal hairs to miniaturized hairs in CTE is 9: 1, in AGA is 2:
1, and in a normal scalp is 7: 1.
Others causes of CTE needs special investigations: insulin
resistant diabetes, obesity Exclusion of Adrenal or Ovarian androgen secreting
tumor (increased 17 DHEAS)
There is always a
great diagnostic dilemma and therefore the line of the treatment between
Pattern Loss (AGA) and CTE (Chronic Telogen Effluvium).
You must have clinical and trichoscopic examination and
following tests to rule out common causes of effluvium (CTE) such as
Thyroid problem, Low Iron, or POCS (Poly cystic ovarian Syndrome-symptoms and signs of androgen excess are present
such as hirsutism, severe unresponsive cystic acne, virilization, or
galactorrhea) or use of contraceptive pills. 1. T3, T4, TSH
2. Free Serum Testosterone, LH/FSH ratio 3. Serum Prolactin
4. Serum Ferritin
5. trans vaginal sonography to rule out polycystic ovaries
3. ATE (Acute Telogen
Effluvium),
A reversible type of female hair loss seen with stress,
pregnancy, drug reactions and a variety of other conditions. Telogen effluvium
generally occurs 2-3 months after a stressful event and affects 35-50% of one’s
hair. Over 300 club hairs (telogen hairs that have rounded ends) can be shed
per day shed. Acute telogen effluvium may
occur in a woman with long-standing AGA or unmask latent AGA. A careful history
will usually identify the cause of profuse hair shedding such as high fever,
severe dietary protein deficiency, or chronic blood loss as in women with
prolonged heavy menses. Relevant laboratory tests are noted above. Categories
of drugs that may cause hair loss include anticancer drugs, anticoagulants,
anticonvulsants, antithyroid drugs, beta blockers, tricyclic antidepressants,
and progestins with androgenic effects (
Besides
densitometry, two other common diagnostic tests that can be performed in the
physician’s office are the hair-pull and hair pluck. In the hair pull, the
physician grabs on to 20-30 hairs with his fingers and gently pulls on them. If
five or more come out in the pull then this is suggestive of the increased
shedding associated with telogen effluvium In the hair pluck, 20 to 30 hairs are forcibly plucked from
the scalp with a small clamp. The hair bulbs are then examined under a
microscope to determine the ratio of anagen (growing) hairs to telogen
(resting) hairs. Normally, at least 80% of the follicles should be in the
anagen stage. A lower ratio would suggest telogen effluvium. With the hair
pluck, various abnormalities of the hair shaft may be observed that can contribute
to hair breakage and poor growth. Laboratory Evaluation for Androgen Excess Occasionally, when a woman presents with female pattern
hair loss, increased androgen production may be a contributing factor. The
following signs and symptoms suggest that specific blood tests might be
appropriate to rule out underlying sources of excess androgen:
Irregular periods – for an
extended period of time
Cystic acne – severe acne
which usually leaves scars
Hirsuitism – increased body
hair that doesn’t normally run in your family
Virilization – appearance of
secondary male sex characteristics such as a deepened voice
Infertility – inability to
become pregnant
Galactorrahea – breast
secretions when not pregnant (this is due to prolactin which is not
actually an androgen)
It is important that when any of these symptoms are
present, or these conditions are being considered, that you are under the care
of a physician, to receive a proper evaluations and correct treatment if
needed. Generally a gynecologist is the specialist most helpful for these
problems. Some of the tests that your doctor might order when
considering androgen excess include:
Total and Free Testosterone – the hormone that is mainly
responsible for male secondary sex characteristics
DHEA-Sulfate – a precursor to testosterone
Prolactin – the hormone that enables the breast to secrete
milk
Diagnostic Tests for Other Medical Conditions Other test that are commonly ordered to screen for
underlying medical conditions include:
CBC (complete blood count) –
for anemia, blood loss and certain vitamin deficiencies
Serum iron and iron binding
capacity – for anemia
T3, T4, TSH – for thyroid
disease
ANA – for Lupus
STS – for Syphilis
4. DUPA 5. Anagen Effluvium Anagen effluvium occurs when hair is shed in its growing phase
and is characterized by large numbers of tapered or broken hairs (>80%). It
can be caused by chemotherapy or radiation and can result in extensive hair
loss in women. Chemotherapy causes a
diffuse type of hair loss called “anagen effluvium” that can be very extensive,
but often reversible when the medication is stopped. C.f. Loose Anagen Syndrome. 6. Hereditary Shaft Disease, Rare condition where the hairs since childhood or birth are
in poor quantity and quality. They may not grow in length and are thin and less
in number all over the scalp. Usually there is no medical answer. Concealer, Wig are the usual answer.
Medications:
1. Minoxidil 2 to
5% local application
2. use of 2% Nizoral
shampoo thrice a week
3. Vitamins ,
Minerals, Nutrient, Iron pills as required
4. Low level Laser
therapy (although of unproven value as now)
5. Estrogen Cream is often beneficial in Female Pattern Loss - to be applied on scalp 2-3 times a week.
This will help to prevent further loss and will help thicken
the existing thin hairs. The medications
do not regrow the lost hairs.
Finasteride, Hormone Pills Aldectone etc. are prescribed by
some practitioners but are of inadequate value and can have may possible
serious side effects so are best avoided.
Finasteride is a competitive inhibitor of type II 5-reductase, and is contraindicated
in women who are or may become pregnant, because 5-reductase inhibitors may cause
abnormalities of the external genitalia of a male fetus. Finasteride was not
effective in postmenopausal women in a placebo-controlled study
Cosmetics:
Use of Cosmetic Concealer like Toppik ( visit
www.toppik.com ) is useful to make the hair look thicker or gives a temporary
cosmetic benefit.
Transplant:
Transplant may be useful in Pattern hair loss and not
for CTE; therefore the accurate diagnosis is essential because the transplant
in CTE will do more damage to your hairs then any help.
Females have usually less dense donor site at the back and
side of the head unlike the males and the Post transplant Effluvium is more
common in Females than in male.
