How to Stop And Reduce Hair Fall – 21 Things That Worked For Me

All of us dream of having healthy, shiny and beautiful locks – hair that would be our crowning glory but unfortunately hair fall seems to have become a constant problem. Hair loss is a common issue that affects millions around the world at some point in their lives. Though hair fall is painless, it can be a distressing experience to lose hair on a daily basis considering that women associate hair with beauty. No one wants to go bald (something many men accept as the natural result of ageing) or look old prematurely.

How many times have you seen your comb or brush covered with hair and felt worried?
Not only while combing but even when oiling or shampooing, hair fall can occur. According to the beauty experts, it is normal to lose about 100 strands of hair in a day. Beyond this may be considered as severe hair fall.

A. What causes Hair Fall?

The common reasons behind hair fall can be perceived as a lack of essential nutrients in the body, excessive use of chemicals through hair coloring and hair styling treatments, improper and unhealthy dietary habits, hormonal imbalance, certain medications, dandruff, alopecia and other scalp disorders.

Even stress and tension can lead to hair fall. Hence try not to let these become a part of your life or if you are stressed out due to some reasons, consider meditation, Yoga or deep breathing exercises to reduce and counter it. Also, make it a point to get adequate sleep every night.
Any medical issues should be taken care of to avoid severe hair fall that can lead to baldness. Thyroid is a common problem affecting thousands of women over the country and this condition may lead to rapid hair fall. So consider getting yourself tested for this after consulting your doctor.

Here is a detailed post on what causes hair loss in women
1. A wide-toothed comb should ideally be used for the hair to gently detangle it and then the regular fine-toothed comb may be used to style the hair as per one’s need. This will reduce the risk of the hair breakage and hair fall while combing.

2. It is best not to comb the hair while it is wet as this leads to greater chances of hair breakage and fall. Let it be dry or semi-dry before combing.

3. Do not rub your hair vigorously with your towel. This will only lead to unwanted hair breakage. Use the towel instead to gently soak out excess moisture.

4. Clean your combs every week. If you look minutely, you will see that combs become unclean and dirty over time; so they need to be cleaned with a brush, soap and water as using that dirty comb continuously can lead to hair fall as well. You can do this easily when taking a bath or shampooing each week. This is a necessary precaution to take for hair fall control.

5. Hot oil treatments is one of the most frequent answers to the question of how to reduce hair fall!

The tradition of oiling the hair to enhance and retain its natural beauty hails from ancient India.
Instead of opting for an expensive parlor treatment, it is best to use natural products that are safe, produce no side effects and are also effective.
Natural oils such as coconut, olive, canola, jojoba, sesame etc. can be used to massage the scalp for countering hair fall and encouraging new hair growth. You have to warm the oil of your choice by heating it; ensure that it’s not too hot but bearable, gently massage your scalp with this using your fingers or even a cotton ball may be used. Next, wear a shower cap, leaving it on for about 1 hour and rinse off using a mild shampoo.

Here is a detailed post on how hot oil massage prevents hair loss.

As we know, hair fall problems can be related to the scalp – issues such as dandruff, dryness and flakiness etc. With a natural hot oil treatment twice every week, the blood circulation in the scalp area can be stimulated causing the hair follicles to stay active and hair loss can be countered through deep conditioning and eliminating these scalp issues, and at the same time your hair receives the much-needed nourishment and care which will help in strengthening and making it beautiful.

6. Try to switch to shampoos that are sulfate, silicone and paraben-free to avoid loading the scalp and hair with harsh chemicals that damage hair, making it brittle and more prone to breakage. Controlling chemical damage is certainly a sure shot way to ensure hair loss prevention.

Some such options are available from brands like The Body Shop, Soul Tree, Rustic Art, Organic Surge; The Nature’s Co. etc

7. Wash your hair at least every 3 days with a gentle hair cleanser or shampoo to remove all accumulated dust, dirt, oil and bacterial build up. Keep it clean at all times to avoid hair fall due to unclean scalp and scalp infections. This is a necessary step to follow as an answer to how to cure hair fall.

Care for Your Hair:

if you have been wondering what more you can do in your quest on how to control hair fall, here are few more suggestions.

8. Do not subject your hair to frequent chemical treatments, excessive blow drying, ironing and coloring as these can lead to hair loss.

9. Hair styles such as wearing tight ponytails, pigtails or braids on a daily basis, using elastics and rubber bands to pull back hair tightly can cause hair fall.

10. Natural Juices to counter hair fall:
An ingredient from our kitchen can effectively help to tackle hair fall problems – it is the good old onion.
It is an amazing natural remedy to fight hair fall and also effectively increases the growth of your hair. Some simple and easy ways to use onion in treating hair fall and promote new hair growth
11. Eat Healthy to Minimize and Prevent Hair Fall:

Give importance to a balanced diet to counter hair loss as this one of the most important answers to your question of how to prevent hair fall. Nutritional deficiencies in the body are a major cause of hair loss.

Classification of Hair Loss in Men

The Norwood classification, published in 1975 by Dr. O’tar Norwood, is the most widely used classification for hair loss in men. It defines two major patterns and several less common types (see the chart below). In the regular Norwood pattern, two areas of hair loss–a bitemporal recession and thinning crown–gradually enlarge and coalesce until the entire front, top and crown (vertex) of the scalp are bald.

Class I represents an adolescent or juvenile hairline and is not actually balding. The adolescent hairline generally rests on the upper brow crease.

Class II indicates a progression to the adult or mature hairline that sits a finger’s breath (1.5cm) above the upper brow crease, with some temporal recession. This also does not represent balding.

Class III is the earliest stage of male hair loss. It is characterized by a deepening temporal recession.

Class III Vertex represents early hair loss in the crown (vertex).

Class IV is characterized by further frontal hair loss and enlargement of vertex, but there is still a solid band of hair across top separating front and vertex.

Class V the bald areas in the front and crown continue to enlarge and the bridge of hair separating the two areas begins to break down.

Class VI occurs when the connecting bridge of hair disappears leaving a single large bald area on the front and top of the scalp. The hair on the sides of the scalp remains relatively high.

Class VII patients have extensive hair loss with only a wreath of hair remaining in the back and sides of the scalp.

Norwood Class A
The Norwood Class A patterns are characterized by a front to back progression of hair loss. Norwood Class A’s lack the connecting bridge across the top of the scalp and generally have more limited hair loss in the crown, even when advanced.


The Norwood Class A patterns are less common than the regular pattern (<10%), but are significant because of the fact that, since the hair loss is most dramatic in the front, the patients look very bald even when the hair loss is minimal. Men with Class A hair loss often seek surgical hair restoration early, as the frontal bald area is not generally responsive to medication and the dense donor area contrasts and accentuates the baldness on top. Fortunately, Class A patients are excellent candidates for hair transplantation.
Diffuse Patterned and Unpatterned Alopecia
Two other types of genetic hair loss in men not often considered by doctors, “Diffuse Patterned Alopecia” and “Diffuse Unpatterned Alopecia,” pose a significant challenge both in diagnosis and in patient management. Understanding these conditions is crucial to the evaluation of hair loss in both men and women, particularly those that are young when the diagnoses may be easily missed, as they may indicate that a patient is not a candidate for surgery. (Bernstein and Rassman “Follicular Transplantation: Patient Evaluation and Surgical Planning”)

Diffuse Patterned Alopecia (DPA) is an androgenetic alopecia manifested as diffuse thinning in the front, top and crown, with a stable permanent zone. In DPA, the entire top of the scalp gradually miniaturizes (thins) without passing through the typical Norwood stages. Diffuse Unpatterned Alopecia (DUPA) is also androgenetic, but lacks a stable permanent zone and affects men much less often than DPA. DUPA tends to advance faster than DPA and end up in a horseshoe pattern resembling the Norwood class VII. However, unlike the Norwood VII, the DUPA horseshoe can look almost transparent due to the low density of the back and sides. Differentiating between DPA and DUPA is very important because DPA patients often make good transplant candidates, whereas DUPA patients almost never do, as they eventually have extensive hair loss without a stable zone for harvesting.

Causes of Hair Loss in Men

By far the most common cause of hair loss in men is androgenetic alopecia, also referred to as “male pattern hair loss” or “common” baldness. It is due to the male hormone dihydrotestosterone (DHT) acting on genetically-susceptible scalp hair follicles that causes them to become progressively smaller and eventually disappear. This process is called “miniaturization.”

This sensitivity to DHT is characteristic of hair follicles that reside in the front, top, and crown of the scalp — rather than the back and sides — producing a characteristic and easily identifiable pattern. This pattern, described by Norwood in his widely used Norwood Classification, typically begins with recession of the hairline at the temples and thinning of the crown. It may progress to total baldness, leaving just a wreath of hair around the back and sides of the scalp.

The Miniaturization of Hair Follicles
DHT is formed by the action of the enzyme 5-alpha reductase on testosterone, the hormone that causes sex characteristics in men. DHT causes male hair loss by shortening the growth, or anagen, phase of the hair cycle, causing miniaturization (decreased size) of the follicles, and producing progressively shorter, finer hairs. Eventually these hairs totally disappear (see image below).
Example 1 – Permanent Zone
In the following patient, we see a close-up of the side of his scalp where the hair is not affected by DHT. We see mostly groups of full thickness hairs (called terminal hairs) and a few scattered fine, vellus hairs, normally seen in a donor area. The pointer (left) indicates the location on the scalp in the close-up view.

Looking at the image above, you can see that the back and sides of the patient’s scalp have not succumbed to the effects of DHT due to follicles’ genetically-inherited resistance to DHT in that area of the scalp. For this reason, the area that covers the back and sides of the scalp is called the permanent zone. Another name is the donor area, because, in a hair transplant, hairs extracted from this part of the scalp are re-implanted into a balding area of the scalp. The follicles retain the DHT-resistance, and so they continue to grow as if they were still in their original location.

Example 2 – Moderate Miniaturization

In the area of thinning (see circle below), we see that most of the hair has been miniaturized, although all of the hair is still present.


The hairs, while still present on the scalp, are so much finer in diameter than the patient’s original hair that they give the visual appearance of thinning.

Example 3 – Extensive Miniaturization

In the region that is balding below (circle in the center of the scalp), there is extensive miniaturization and only very little loss of actual hairs. However, due to the dramatic thinning of the hair diameter, there is an appearance of almost complete balding in the area despite the presence of fine hair.
What these examples show is that, particularly in the early stages, the appearance of balding is due to the progressive decrease in hair shaft size caused by the miniaturizing effects of DHT, rather than the actual loss of hair.

This is the reason why hair loss medications, such as finasteride (Propecia) or minoxidil (Rogaine), which can reverse the miniaturization process, work well in early hair loss and why, with early hair loss, a surgical procedure is usually not necessary. If medications fail to restore enough hair, or if a patient chooses not to use medical therapy, then a hair transplant may be considered. Certainly, if an area is completely bald, medications will not re-grow hair and surgery can be considered as a first option.

Androgenetic Hair Loss: Genes, Hormones, Age
The expression of Androgenetic hair loss is affected by three interdependent factors: genes, hormones, and age:

Genes

It is frequently stated that “hair loss comes from the mother’s side of the family.” The truth is that baldness can be inherited from either parent. However, factors on the x-chromosome have been shown to influence hair loss, making the inheritance from the maternal side of the family slightly more important than the paternal one.

Recent research suggests that the genetics in male pattern hair loss is more complex than originally thought. The identification of an androgen receptor gene (AR) on the x-chromosome helps to explain why the hair loss pattern of a man resembles his maternal grandfather more often than his father. However, this is clearly not the whole story since a direct inheritance of baldness from the father is observed as well. An autosomal (non-sex) linked gene would explain this type of transmission – but this gene has not yet been found.

By the way of background, a gene is a single bit of chemically encoded hereditary instruction that is located on a chromosome and actually represents a tiny segment of DNA. Chromosomes occur in pairs (humans have 23 pairs), and every individual gets one set of chromosomes from each parent. Hair loss in men is now felt to involve more than one gene. When several genes govern a trait, it is called polygenic.

Genes that are located on the X or Y-chromosomes are call sex-linked. Genes on the other 22 pairs of chromosomes are called autosomal. It is felt that the genes governing common baldness are both sex-linked and also autosomal (not sex linked). This means that the baldness trait can be inherited from the mother’s side of the family or the father’s side, but not necessarily with equal frequency.

The term, “dominant” means that only one gene of a pair is needed for the trait to show up in the individual. A “recessive” gene means that both genes need to be present in order for the trait to be expressed. The most important genes involved in balding from androgenetic alopecia are felt to be dominant.

Just because one has the genes for baldness, it doesn’t mean the trait will manifest itself. The ability of a gene to affect one’s characteristics, i.e. be visible in a particular individual, is called “expressivity”. Gene expression is related to a number of factors, the major ones being hormones and age, although stress and other factors can be reasons for hair loss in some individuals.

It is of interest that, although genes for some types of hair loss have been mapped, the genes responsible for male pattern baldness have yet to be fully identified. This suggests that any kind of genetic engineering to prevent common baldness is still many years away.

Hormones

Hormones are biochemical substances that are made in various glands throughout the body. These glands secrete their products directly into the bloodstream so that the chemical they make is spread throughout the body. These chemicals are very powerful so that only minute amounts of them have profound effects upon the body.

The major male sex hormone is called testosterone. Testosterone and other related hormones that have masculinizing effects are made primarily in the testicles; therefore, the hormonal levels that are seen in adults do not reached significant levels until the testicles develop and enlarge during puberty. In fact, these same hormones are the cause of many of the changes that occur in puberty; growth of phallus and scrotum, sperm production, development of a sex drive, change in the voice, Read about the discovery of the relationship between testosterone and hormonally-induced hair lossgrowth of axillary and pubic hair, development of an adult aroma in the sweat, increase in bone and muscle mass, and change in the basic body shape.

These same hormones that cause acne and beard growth can also signal the beginning of baldness. The presence of androgens; testosterone, and its related hormone DHT, cause some follicles to regress and die. In addition to the testicles, the adrenal glands located above each of our kidneys, produce androgenic hormones, and this would be similar in both sexes. In females, the ovaries are an additional source of hormones that can affect hair.

The hormone felt to be directly involved in androgenetic alopecia is actually dihydrotestosterone (DHT) rather than testosterone. DHT acts by binding to special receptor sites on the cells of the hair follicles to cause the specific changes associated with balding. DHT is formed by the action of the enzyme 5-a reductase on testosterone. In men, 5-a reductase activity is higher in the balding area. This helps to explain the reason for the patterned alopecia that males experience. The enzyme 5-a reductase actually comes in two forms, Type 1 and Type 2. The enzyme 5-alpha reductase Type II, the predominant form in hair follicles, is blocked by the hair loss medication finasteride (Propecia).

DHT decreases the length of the anagen (growing) cycle, and increases the telogen (resting) phase, so that with each new cycle the hair shaft becomes progressively smaller. In addition, DHT causes the bi-temporal reshaping of hairline seen as adolescents enter adulthood, as well as patterned baldness (androgenetic alopecia). DHT also causes prostate enlargement in older men and adolescent and adult acne.

It is interesting that testosterone effects axillary and pubic hair, whereas DHT effects beard growth, hair on torso and limbs, patterned baldness and the appearance of hair in the nose and ears (something that older men experience). Scalp hair growth, however, is not androgen dependent, only scalp hair loss depends on androgens.

Age

The presence of the necessary genes and hormones is not alone sufficient to cause baldness. Even after a person has reached puberty, susceptible hair follicles must continually be exposed to the hormone over a period of time for hair loss to occur. The age at which these effects finally manifest themselves varies from one individual to another and is related to a person’s genetic composition and to the levels of testosterone in the bloodstream.

There is another time factor that is poorly understood. Male hair loss does not occur all at once or in a steady, straight-line progression. Hair loss is characteristically cyclical. People who are losing their hair experience alternating periods of slow and rapid hair loss and even stability. Many of the reasons that hair loss rates speed up and speed down are unknown, but we do know that with age, a person’s total hair volume will usually decrease.

Even when there is no predisposition to genetic balding, as a patient ages, some hairs randomly begin to miniaturize (shrink in length and width) in each follicular unit. As a result, each group will contain both of full terminal hairs and miniaturized hairs (similar to the very fine hairs that occur on the rest of the body and are clinically insignificant) making the area look less full. Eventually, the miniaturized hairs are lost, and the actual follicular units are reduced in number. In all adult patients, the entire scalp undergoes this aging process so that even the donor zone is not truly permanent, but will gradually thin, to some degree, over time. Fortunately, in most people, the donor zone retains enough permanent hair that hair transplantation is a viable male hair restoration procedure even for a patient well into his 70s.
