What is the normal cycle of hair growth and loss?
Hair growth lasts for 2 to 3 years. Each hair grows approximately 1 centimetre per month during this phase. About 90 percent of the hair on your scalp is growing at any one time. About 10 percent of the hair on your scalp, at any one time, is in a resting phase. After 3 to 4 months, the resting hair falls out and new hair starts to grow in its place.
It is normal to shed some hair each day as part of this cycle. However, some people may experience excessive (more than normal) hair loss. Hair loss of this type can affect men, women and children.
What causes excessive hair loss?
A number of things can cause excessive hair loss. For example, about 3 or 4 months after an illness or a major surgery, you may suddenly lose a large amount of hair. This hair loss is related to the stress of the illness and is temporary.
Hormonal problems may cause hair loss. If your thyroid gland is overactive or underactive, your hair may fall out. This hair loss usually can be helped by treatment of thyroid disease. Hair loss may occur if male or female hormones, known as androgens and estrogens, are out of balance. Correcting the hormone imbalance may stop your hair loss.
Many women notice hair loss about 3 months after they've had a baby. This loss is also related to hormones. During pregnancy, high levels of certain hormones cause the body to keep hair that would normally fall out. When the hormones return to pre-pregnancy levels, that hair falls out and the normal cycle of growth and loss starts again.
Some medicines can cause hair loss. This type of hair loss improves when you stop taking the medicine. Medicines that can cause hair loss include blood thinners (also called anticoagulants), medicines used for gout, high blood pressure or heart problems, vitamin A (if too much is taken), birth control pills and antidepressants.
Certain infections can cause hair loss. Fungal infections of the scalp can cause hair loss in children. The infection is easily treated with antifungal medicines.
Finally, hair loss may occur as part of an underlying disease, such as lupus or diabetes. Since hair loss may be an early sign of a disease, it is important to find the cause so that it can be treated.
Can certain hairstyles or treatments cause hair loss?
Yes. If you wear pigtails or cornrows or use tight hair rollers, the pull on your hair can cause a type of hair loss called traction alopecia (say: al-oh-pee-sha). If the pulling is stopped before scarring of the scalp develops, your hair will grow back normally. However, scarring can cause permanent hair loss. Hot oil hair treatments or chemicals used in permanents (also called "perms") may cause inflammation (swelling) of the hair follicle, which can result in scarring and hair loss.
What is common baldness?
"Common baldness" usually means male-pattern baldness, or permanent-pattern baldness. It is also called androgenetic alopecia. Male-pattern baldness is the most common cause of hair loss in men. Men who have this type of hair loss usually have inherited the trait. Men who start losing their hair at an early age tend to develop more extensive baldness. In male-pattern baldness, hair loss typically results in a receding hair line and baldness on the top of the head.
Women may develop female-pattern baldness. In this form of hair loss, the hair can become thin over the entire scalp.
Can my doctor do something to stop hair loss?
Perhaps. Your doctor will probably ask you some questions about your diet, any medicines you're taking, whether you've had a recent illness and how you take care of your hair. If you're a woman, your doctor may ask questions about your menstrual cycle, pregnancies and menopause. Your doctor may want to do a physical exam to look for other causes of hair loss. Finally, blood tests or a biopsy (taking a small sample of cells to examine under a microscope) of your scalp may be needed.
Is there any treatment for hair loss?
Depending on your type of hair loss, treatments are available. If a medicine is causing your hair loss, your doctor may be able to prescribe a different medicine. Recognising and treating an infection may help stop the hair loss. Correcting a hormone imbalance may prevent further hair loss.
Medicines may also help slow or prevent the development of common baldness. One medicine, minoxidil (brand name: Rogaine), is available without a prescription. It is applied to the scalp. Both men and women can use it. Another medicine, finasteride, is available with a prescription. It comes in pills and is only for men. It may take up to 6 months before you can tell if one of these medicines is working.
If adequate treatment is not available for your type of hair loss, you may consider trying different hairstyles or wigs, hairpieces, hair weaves or artificial hair replacement.

Many men and women use chemical treatments on their hair, including dyes, tints, bleaches, straighteners, and permanent waves. These treatments rarely damage hair if they are done correctly. However, the hair can become weak and break if any of these chemicals are used too often. If hair becomes brittle from chemical treatments, it is best to stop until the hair grows out.

Thank you sir for your valuable information about hair lass.

Hair is made of a protein called keratin plus amino acids, and each strand is like a power cord: It has an outer sheath, or cuticle, that encases the inner cortex. The cuticle can withstand abuse such as heat and brushing — to a point. Even durable strands can use a jolt of support.
Ruffles may be a big fashion trend, but hair looks best when its cuticles — which are composed of cells that overlap like shingles on a roof — remain flat. If they’re on an even plane, light bounces off, creating a high sheen. These tricks will keep hair in prime-shine condition.

Hair grows in cycles. For each hair cycle there are three phases
1. Growth Phase: - When the cells at the scalp start multiply rapidly, a new hair start to growth. Those cells, together with keratin and other proteins form the hair.
2. Transitional Phase: there is a period of 2-3 weeks after the growth of the hair stops.
3. Resting Phase: - usually lasts 2-3 months, when the hair follicle rests. At the end of this phase the older hair is shed, and a new cycle begin.

Sir,
Please tell me can using of shampoo be a reason of hair fall??? which shampoo we all should use or is it safe?????
Thank you.

Thank you Baset Sir for giving more information.

Sodium Lauryl Sulfate (SLS) is the ingredient in shampoo that has been singled out as the offending culprit. If you use shampoo then you’re drenching your head in SLS – it’s found in over 95 percent of commercial shampoos. SLS is a potent de-greaser, acting as a surfactant, binding to the dirt and gunk on your hair and scalp. After rinsing your hair, the grime is dragged down the plug hole by the SLS. SLS takes no prisoners, dirt is zapped away and your hair is left bright and bouncy. Yet even after rinsing SLS residue may have taken up camp in and on your scalp. Exposure itself may be enough to cause problems.

Stress and Hair Loss
You may have heard that stress can cause hair loss, and it’s true. Excessive physical or emotional stress, like that associated with injury, illness or surgery, can cause one of two types of hair loss:
* The more common type is called telogen effluvium. With this less severe type of hair loss, the hair stops growing and lies dormant, only to fall out 2 or 3 months later. Then it grows back within 6 to 9 months.
* The other type of stress-induced hair loss is known as alopecia areata, and involves a white blood cell attack on the hair follicles. With this type of hair loss, the hair also falls out within weeks (usually in patches), but can involve the entire scalp and even body hair. Hair may grow back on its own, but treatment may also be required.

When male-pattern baldness begins, the hair becomes increasingly thinner and thinner until it is eventually altogether gone. The root cause of this is the human hormone known as dihydrotesttosterone otherwise called (DHT). When there is an over abundance of DHT in the scalp, it attaches itself to the hair follicles thus blocking the blood supply and interrupting their growth. As time continues, the follicles, deprived of the necessary nutrients, shrink and the hair shaft width is decreased. The hair gets thinner as a result of this. When a hair shaft has become to small then no new hair may continue to grow from the follicle.

Winter Hair Care Tips
Wear a scarf, hat or cap to protect your hair from the cold and wind. Make sure that it's not so tight where it will restrict circulation in your scalp.
Use a conditioner daily.
Once you have your hair moist, lock in the moisture by running your hair through cold water; this will also give your hair an extra shine.
Don't go outside with your hair wet, you risk breakage. Your hair will freeze if it's cold enough outside and may break.
Limit your use of "hot" items on your hair such as a blow dryers and curling irons.
If you need to use a "hot" item use a leave in conditioner before using the item on your hair.
Avoid taking hot showers or washing your hair in hot water. Use warm or cool water instead, the heat can dry out and/or damage your hair and skin.
Hair products that have the word, "Replenish" on it is made to moistureize your hair.
Try using a dry shampoo if you need to wash out your hair. One dry shampoo you can use is baby powder, simply sprinkle some onto your hair and use a comb to comb it off

Protect hair Loss Easy 6 Ways !!!
1. Drink Water: Drinking pure water is a good therapy to prevent loss hair. Water helps clean harmful toxins from our body which can be often major causes for hair loss. So, it is make sure that you drink at least 8-10 glasses of water daily to prevent hair loss.
2. Protein: Hair is actually made from protein. So, protein is necessary to prevent their loss. Experts say that an average adult should consume about 46 to56 grams protein daily.
3. Diet: You should take always fresh fruits and vegetables including vitamins A (eggs, squash, pumpkin, mangoes, carrots), C (Alma, guava, lemon and citrus fruits), and E (wheat germ, almond, avocado, coconut) for your health and stronger hair.
4. Iron: It’s a widely known fact that iron deficiency can cause hair loss. Iron is needed to raise your hair which is producing oxygen-toting hemoglobin and it is necessary for healthy hair.
5. Hormonal Imbalance: Another reason for hair loss is hormonal imbalance. Most of the women are facing this problem within 3-4 months after childbirth. You have to make sure that you are taking good nutrition food during pregnancy.
6. Smoking: Smoking is always dangerous for health. But it is also bad for hair growth. Smoking prevents good blood supply in our body and this cause to prevent hair growth.
