also known as alopecia or baldness, refers to a loss of hair from part of the head or body.
Typically at least the head is involved.
The severity of hair loss can vary from a small area to the entire body.
Typically inflammation or scarring is not present.
Hair loss in some people causes psychological distress.
Common types include: male-pattern hair loss, female-pattern hair loss, alopecia areata, and a thinning of hair known as telogen effluvium.
The cause of male-pattern hair loss is a combination of genetics and male hormones, the cause of female pattern hair loss is unclear,
the cause of alopecia areata is autoimmune, and the cause of telogen effluvium is typically a physically or psychologically stressful event.
Telogen effluvium is very common following pregnancy.
Less common causes of hair loss without inflammation or scarring include the pulling out of hair, certain medications including chemotherapy, HIV/AIDS, hypothyroidism, and malnutrition including iron deficiency.
Causes of hair loss that occurs with scarring or inflammation include fungal infection, lupus erythematosus, radiation therapy, and sarcoidosis.
Diagnosis of hair loss is partly based on the areas affected.
True. Hair loss can be hereditary.
Hereditary hair loss is called androgenetic alopecia, or for males, male pattern baldness, and for females, female pattern baldness.
Androgenetic alopecia occurs when a hair follicle sheds, and the hair that replaces it is thinner and finer than what was there previously.
The hair follicles continue to shrink and eventually hair stops growing altogether.
However, contrary to popular belief, hereditary hair loss is not only inherited from the maternal side –
it can be passed down from either the mother’s or father’s genes – but is more likely to occur if both parents have this issue.
False. Many people tend to think that over-shampooing can cause hair loss because a lot of the time our hair falls out naturally in the shower, and it may seem like more hair falling out than normal.
Somewhat true. If you have hereditary hair loss, what you inherit are hair follicles that have a higher sensitivity to DHT, which is a hormone composed of one type of testosterone.
If testosterone were the only cause of hair loss though, all hair on your body would be expected to fall out.
False. Hats, beanies, and the like do not cause hair loss.
Mostly False. UV radiation cannot interrupt hair follicle creation, but overexposure can weaken hair follicles by causing dullness and breakage.
Hair grows in three different cycles: anagen, catagen, and telogen. About 90% of the hair on the head is in the anagen, or growth phase, which lasts anywhere from two to eight years.
The catagen, or transition phase, typically lasts 2-3 weeks, during which the hair follicle shrinks.
During the telogen cycle, which lasts around two to four months, the hair rests.
Most people lose anywhere from 50 to 100 strands of hair each day, according to the American Academy of Dermatology.
On the days when hair is washed, people can lose up to 250 strands, Roberts said.
But don’t avoid washing in an attempt to keep the hair, as it will fall out eventually, anyway.
For those who don’t plan on counting their hair every day, there are ways to know when hair is thinning or being lost at a higher rate.
Roberts tells WebMD that women will see a difference. When waking up in the morning, there may be an usually large amount on your pillow.
When you comb your hair (especially without tugging, which can pull the hair out), more than normal will be left in the comb.
One other way to thin hair is self-inflicted – hairstyles like cornrows or too-tight braids can cause hair loss called traction alopecia.
dyes, chemical treatments, bad brushes, blow dryers, and flat irons — can result in damage and breakage, Roberts says.
This includes brushing too much and towel drying aggressively when the hair is wet.
Luckily, for most of these issues,
the hair grows back or the loss can be reversed with medical treatments. But it is important to see a dermatologist if there seems to be something wrong,
because the sooner treatment is started,
the better the chances are for improving your growing season.
vitamin d deficiency can lead to hair loss
Vitamin D stimulates hair follicles, so a deficiency may lead to hair loss.
There is some evidence that having a vitamin D deficiency does cause hair loss and other hair problems. Vitamin D stimulates hair follicles to grow,
and so when the body does not have enough, the hair may be affected.
A vitamin D deficiency may also be linked to alopecia areata, an autoimmune condition that causes patchy hair loss.
Research shows that people with alopecia areata have much lower levels of vitamin D than people who do not have alopecia.
Vitamin D deficiency can also play a role in hair loss in people without alopecia.
Other research shows that women who have other forms of hair loss also had lower levels of vitamin D.
Vitamin D affects the health of many parts of the body, including the skin and hair.
Vitamin D plays a role in the creation of new hair follicles.
Hair follicles are the tiny pores from which new hairs grow.
New follicles may help hair maintain thickness and prevent existing hair from falling out prematurely.
Because of this link, getting adequate amounts of vitamin D can support hair growth and regrowth.
A person’s first defense against hair loss caused by a vitamin D deficiency is spending 15 to 20 minutes outside per day and eating foods that are rich in vitamin D.
A person may also want to add a vitamin D supplement to their routine to support their vitamin D intake goals.
Brittle or sparse hair requires gentle treatment, so anyone experiencing hair loss can prevent further breakage by:
not pulling the hair when brushing
avoiding ponytails and other tight hairstyles
using a gentle and natural conditioner
putting long hair in a loose braid before bed to prevent tangling
Hair transplantation is usually carried out under local anaesthetic.
A surgeon will move healthy hair from the back and sides of the head to areas of thinning.
The procedure can take between four and eight hours,
and additional sessions can be carried out to make hair even thicker.
Transplanted hair falls out within a few weeks, but regrows permanently within months.
Hair transplants, takes tiny plugs of skin, each which contains a few hairs, and implants the plugs into bald sections.
The plugs are generally taken from the back or sides of the scalp. Several transplant sessions may be necessary.
Surgical options, such as follicle transplants, scalp flaps, and hair loss reduction, are available.
These procedures are generally chosen by those who are self-conscious about their hair loss, but they are expensive and painful, with a risk of infection and scarring.
Once surgery has occurred, six to eight months are needed before the quality of new hair can be assessed.
Scalp reduction is the process is the decreasing of the area of bald skin on the head.
In time, the skin on the head becomes flexible
and stretched enough that some of it can be surgically removed.
After the hairless scalp is removed, the space is closed with hair-covered scalp.
Scalp reduction is generally done in combination with hair transplantation to provide a natural-looking hairline, especially those with extensive hair loss.
Hairline lowering can sometimes be used to lower a high hairline secondary to hair loss,
although there may be a visible scar after further hair loss.
Wigs are an alternative to medical and surgical treatment; some patients wear a wig or hairpiece.
They can be used permanently or temporarily to cover the hair loss.
High-quality, natural-looking wigs and hairpieces are available.
I hope that this post can be help u to have better hair 🙂
