| Hair Thinning and Loss: Causes, Prevention, and Treatments |
Understanding Hair Thinning and Loss
The Hair Growth Cycle
Hair follicle growth occurs in cycles. Periods of
quiescence and regression caused by apoptotic signals alternate with stages of
the hair shaft's fast development and extension. Three phases make up this
cycle: telogen (rest), catagen (transition), and anagen (growth).
Anagen growth
is the active stage, when the hair follicle starts to
resemble an onion and begins producing hair fiber. The duration of the anagen
phase might span multiple years.
The catagen phase
starts at the conclusion of the anagen phase and is
distinguished by the entry into quiescence. This phase, which can extend to
several weeks, is characterized by regression of the hair follicle caused by
apoptosis and a loss of approximately one-sixth of its normal diameter.
The telogen or resting phase
wherein the hair shaft does not develop and the hair follicle is inert. At any given time, between 10 and 15 percent of all body hairs are in this resting phase, and they can stay there for a variety of lengths of time.
Common Causes of Hair Thinning and Loss
Genetic Factors, hormonal, nutritional, and
life style are the most causes for hair thinning and loss, as follow:
1-Genetic Factors
The role of genetics in pattern baldness (androgenetic
alopecia)
Androgenetic alopecia
A prevalent cause of hair loss in both men and women
is androgenetic alopecia. It is sometimes referred to as female pattern hair
loss in women and male pattern baldness in men.
Women experience hair loss in a different pattern than
males do. Women's hair spreads in the middle and gets thinner at the top of the
head. Usually, the hairline does not recede.
Complete baldness is an uncommon outcome of androgenetic alopecia in
women.
Researchers have found that androgens, primarily the
hormone dihydrotestosterone (DHT), are linked to this type of hair loss,
especially in men. Female pattern hair loss is partially caused by androgens,
but there may be additional, as-yet-unidentified variables at play.
2-Hormonal Imbalances
Changes in hormones and their effects on hair
health.Disorders such as thyroid issues and polycystic ovarian syndrome (PCOS)
Hormones have a close association with hair growth;
thus, they have a big impact on the hair cycle and hair follicle structure.
Androgens
Di-hydro
testosterone and testosterone, they influencing the activity and maturity of hair
follicle keratinocytes, which results in male patterned hair loss. As a result,
scalp hairs get increasingly thinner.
Estrogen
Estrogens, on the other hand, have long been known to
have a significant impact on hair follicle changes affecting the growth of hair
follicles.
Insulin and Insulin-Like Growth Factor (IGF)
These hormones function in concert with androgens to
stimulate hair formation. By increasing 5α reeducates activity, hyperinsulinemia
may increase the production of dihydro testosterone and cause male-pattern hair
loss.
Prolactin
Promotes the hair shaft lengthening, Prolactin excess is linked to hirsutism in clinical
studies, most likely due to the stimulation of hyperandrogenism.
Melatonin
Has a significant impact on the protection of hair
follicles from oxidative stress and thus to inhibit hair growth suppression.
Cortisol
High levels of cortisol are linked to a decrease in the formation a hair follicle modulators, which are essential for hair follicle activity.
thyroid hormones
The thyroid hormone is believed to be responsible for regulating the
hair cycle's frequency [26]. Hypothyroidism causes a decrease in anagen
frequency, whereas hyperthyroidism causes thin hairs.
Pregnancy
While a decrease in oestrogen circulation during the
postpartum period is believed to be a contributing factor to telogen
gravidarum, or postpartum hair loss, high oestrogen circulation levels may help
prolong anagen.
Polycystic ovary syndrome (PCOS)
Because PCOS is linked to higher-than-normal
testosterone levels, which have an impact on hair growth, PCOS may be a
contributing factor in hair loss. This condition is referred to as androgenic
alopecia, and women frequently report hair loss in the frontal areas of their
scalp and around their temples.
3-Nutritional Deficiencies
The importance of a balanced diet for healthy hair
Key nutrients for hair growth and their food sources
Hair follicle cells are among the most rapidly
dividing cells in your body, so it’s no surprise that nutrient deficiencies can
negatively affect hair growth .
Iron
The most prevalent vitamin shortage in the world, iron
deficiency, can result in hair loss.
According to certain research, those who experience
hair loss typically have lower blood and hair iron levels than those who do not.
Vitamin D
Studies have indicated that individuals with
autoimmune skin diseases such as alopecia areata and female pattern hair loss
have reduced vitamin D levels.
Zinc
Zinc is a mineral that is essential for cellular division,
protein synthesis, immune system function, and other processes.
It helps prevent hair follicle shrinking and slower
growth and is essential for the health of hair follicles.
Zinc levels in several hair loss diseases are
typically lower than in healthy individuals. Those prerequisites consist of:
Alopecia areata
Male-pattern hair loss
hair loss in women
Copper, biotin, vitamin B12, folate, and riboflavin
are additional minerals that may have an impact on hair loss.
Alopecia areata and hair thining and loss
American academy of dermatology
Hair loss can take many different forms. Alopecia
areata is among the more prevalent varieties.Though it as autoimmune disorder
and can occur at any age, this kind of hair loss typically starts in children
and young people. Alopecia areata affects people of all genders and skin tones.
"Areata" translates to "patchy." This condition is typically referred to as alopecia areata since it frequently results in patchy hair loss. "Alopecia" refers to baldness.
4-Life style and hair thining and loss
1- Stress and hair thining and loss
Stress and hair loss have a well-established
correlation. Numerous factors, including hereditary and environmental ones,
contribute to hair loss.
Acute stress strengthens the immune system; chronic
stress, on the other hand, inhibits and overactivates the immune system, which
results in inflammation.
Chronic, long-term stress can lead to inflammation
within or surrounding the follicle, which can interfere with its functions by
way of neuroimmune and endocrine mediators such as hormones that release
cortisol and corticotropin.
2-Sleep and hair thining and loss
Not getting enough sleep might damage hair follicles
and have an impact on hormone release. Hair may seem thin, dry, and dull as a
result. It's important to remember that while inadequate sleep does not
necessarily result in alopecia, it can cause hair density to decrease.
3-The effects of smoking, excessive alcohol and hair thing and loss
Yes, you can slow down hair loss by cutting back on or
giving up alcohol and smoking. Smoking and binge drinking can also be harmful
to the health of your hair. because drinking alcohol and smoking restrict blood
and oxygen flow to the hair.
Prevention and treatment and Lifestyle modifications for hair thinig and loss
A. Maintain a Healthy Diet
Consuming a well-balanced diet high in essential
vitamins and minerals might help stimulate hair growth, particularly if you are
losing hair as a result of malnutrition.Make sure you're receiving enough of
these foods high in micronutrients even if more research is needed to fully
understand the relationship between micronutrients and hair loss. Add meals
high in iron, zinc, and selenium, as well as vitamins A, C, D, and E, which
promote hair development.
B. Adopt a Hair Care Routine
Selecting the appropriate shampoo and conditioner for
your type of hair
Starting with a pre-wash treatment and steering clear
of harsh chemical treatments and extreme heat styling
Select an anti-hair loss shampoo that is specifically designed for your needs; proceed with an extremely nourishing conditioner; and stimulate hair growth with a scalp treatment.
C. Stress Management Techniques
Including mindfulness or meditation in your daily routine
can assist quiet and soothe a stressed-out mind. These relaxation practices can
also help restore peace. It has been shown that even a short daily meditation
session can significantly reduce stress and help break the vicious cycle of
stress that leads to hair loss. Additionally, schedule time for your favorite
pastimes and other enjoyable pursuits that can help you unwind after a
stressful day.
D. Effective Medications and other treatments options for Hair Thinning and Loss
Medications
are available to treat pattern
(hereditary) baldness. The most common options include:
Minoxidil (Rogaine).
Minoxidil is available over-the-counter (without a
prescription) as a liquid, foam, and shampoo. Apply the cream to the scalp skin
once a day for ladies and twice a day for men for optimal results. The foam
applied while the hair is still damp is preferred by many.
Many individuals find that using minoxidil-containing
products helps either stop or delay the rate of hair loss. Treatment must be
administered for at least six months in order to stop more hair loss and
initiate hair regrowth.
Finasteride (Propecia)
This prescription medication treats a specific type of
alopecia (male baladness) by blocking the body's entire testosterone synthesis.
Pregnant or potentially pregnant women should not
handle broken or crushed medications.
Other medications.
Additional oral treatments include of oral dutasteride
(Avodart) and spironolactone (Carospir, Aldactone).
OTHER TREATMENT OPTIONS
A. Platelet-Rich Plasma (PRP) Therapy
The three-step medical procedure known as PRP
(platelet-rich plasma) therapy for hair loss involves drawing, processing, and
injecting the patient's blood into the scalp.
Certain members of the medical community believe that
PRP injections thicken the hair shaft and increase blood flow to the hair
follicle, which in turn promotes and sustains natural hair growth. This method
is occasionally used in conjunction with other hair loss treatments or drugs.
B. Hair Transplantation
The most frequent reason for hair transplant surgery is pattern hair loss, which includes both male pattern hair loss (MPHL), also known as androgenic alopecia (AGA), and female pattern hair loss (FPHL). Not every one of these patients, nevertheless, qualifies for hair transplantation. Patients who don't qualify as suitable candidates have eight conditions. These include patients with cicatricle alopecia (CA), diffuse unpatented alopecia (DUPA), patients with unstable or insufficient hair loss, very young patients, and patients with irrational expectations, patients with psychological disorders like trichotillomania and body dimorphic disorder (BDD), and patients who are medically unfit.
Conclusion
Numerous causes can contribute to hair thinning and loss, thus treating it holistically is necessary. You can take charge of your hair health by comprehending the causes, putting preventative measures into place, and investigating efficient therapies. Remember that the best results depend on prompt action and skilled assistance. Accept the path to getting shiny hair and self-assurance again.
