Does Vitamin D3 Deficiency Cause Hair Loss?

In about 1 in 5 women with breast cancer, the cancer cells have too much of a growth-promoting protein known as HER2 on their surface. These cancers, known as HER2-positive breastcancers, tend to grow and spread more aggressively. Different types of drugs have been developed that target the HER2 protein.

Anastrozole And Side Effectshair Loss/thinning And Hair Regrowth

I started taking anastrozole in May 2018. The worst side effect I had was hot flashes, but I was undergoing radiation and it was a particularly hot summer here. My Dr took me off it for two weeks and I restarted it in September. I have had very few problems. The first time I had BC, I took tamoxifen and I think that bothered me more. I was anticipating problems this time. The hot flashes are goneI never had them before in my life! I have random aches and pains. One joint in my foot seems to be tender, but it is something I can easily live with. One thing I did notice was the hair thinning. I had it with the tamoxifen and now with this. It really bothered me, but has anyone else had their hair start to grow back? I had searched the internet for a natural substance to help hair growth and found castor oil. Needless to say, I was skeptical. I put it on a cotton ball and dab it lightly on the areas by my temples and my natural hair part and my hairline by my forehead. It is an easy fix if it is a fix. Recently I have noticed new hair growth in the temple areas and in my hair part. It is about an inch + long. It is not as if my hair has suddenly thickened up a lot, but there is a difference. I am not sure if I am just getting used to the medicine or if the castor oil has any effect, but there is a difference. For me, there is an improvement, so I just wanted to let you know that there may be hope for improvement for other people.

How Hormonal Imbalance Causes Hair Loss

Thyroid disease is a common culprit among many medical conditions that cause hair loss.

Healthy hair growth depends on the proper functioning of the thyroid gland. Unusual levels of thyroid hormone produced by this gland can result in hair loss and other side effects if left untreated. Too much thyroid hormone can cause hair thinning. The deficiency of this hormone, known as hypothyroidism in medical terms, can lead to hair loss.

Stress can influence your hormone balance. Cortisol, known as the stress hormone helps your body deal with stress in a long term. Adrenaline, commonly known as the fight or flight hormone, is produced by the adrenal glands after receiving a message from the brain that a stressful situation has presented. In primitive days, these hormones were provoked in survival mode as responses to threats from predators. Nowadays, they are triggered when people are overwhelmed by the fast-paced lifestyle, resulting in an increase in hormonal imbalances.

Tamoxifen is the most commonly used anti-estrogen drug. It is used in post-menopausal and premenopausal women. Tamoxifen is given by mouth as a pill.

Tamoxifen is the hormonal therapy drug used most often to lower the risk that DCIS or LCIS will lead to an invasive breast cancer.

Tamoxifen very slightly increases the risk for uterine cancer, deep vein thrombosis and stroke. Doctors will carefully weigh these risks against the benefits of giving this drug before they offer it to women who have a personal or a strong family history of these conditions. Usually the benefits of taking tamoxifen outweigh these risks.


Fulvestrant is an anti-estrogen drug that reduces the number of estrogen receptors on breast cancer cells. It is given as an injection into the muscles of the buttocks.

Fulvestrant is used in post-menopausal women if the breast cancer has grown after they were treated with tamoxifen. It is also used in postmenopausal women with locally advanced or metastatic breast cancer that have never been treated with hormonal therapy.

Aching Or Pain In The Joints And Muscles

Aching or pain in the joints and muscles is often mild and temporary, although for some people its more severe and longer lasting.

It can usually be relieved with mild pain relief like paracetamol or an anti-inflammatory drug such as ibuprofen. Before using anti-inflammatory pain relief, ask your doctor about the correct dose, how long you should use it for and any possible side effects, especially if you have a stomach ulcer or asthma.

Exercise that gently stretches your joints or strengthens your muscles to better support your joints, such as yoga or pilates, may help improve your symptoms. A physiotherapist may also be able to suggest exercises to help. If you have secondary breast cancer, check with your specialist before starting any new type of exercise.

If the pain is severe, your specialist may refer you to a rheumatologist . It may also be helpful to see a pain management specialist at a pain clinic.

Some people benefit from switching to a different hormone therapy. For example, it may be possible to switch to another aromatase inhibitor to see if your pain improves, or some people might be offered the drug tamoxifen as an alternative.

Why Chemo Causes Hair Loss

Hair loss is very common during chemotherapy for breast cancer as well as other cancers, though some drugs and methods of administration are more likely than others to disrupt hair follicles.

Chemotherapy drugs work systemically by interfering with the division and growth of rapidly growing cells.

While these drugs can be effective in eliminating cancer cells, they also damage normal cells that divide rapidly. This includes hair follicles , cells in the digestive tract , and cells in bone marrow .

The keratinocytes in the hair follicle divide faster than many malignant cells, and they have a good blood supply that delivers chemotherapy agents to them efficiently. Their fast metabolism also puts them under oxidative stress, which a chemotherapy drug can enhance to the point that the cell dies.

Whether or not you develop hair loss, and the degree to which you do if so, depends on a number of factors including:

  • The dose of chemotherapy: Higher doses generally have a greater risk for hair loss.
  • How often the chemotherapy is given: More frequent doses carry more risk.
  • The route of administration: Intravenous drugs are more likely to cause hair loss than oral drugs.
  • The drugs or combination of drugs you receive: Some are more likely to cause hair loss than others, and receiving a combination of drugs increases the risk.
  • Your individual makeup: Some people are more likely to lose hair than others, even with the same doses of the same drugs.

Taking Levothyroxine Might Cause Hair Loss

Levothyroxine is a thyroid medicine given to regulate the bodys energy and metabolism by replacing a hormone that thyroid does not produce enough on its own. Each month doctors currently hand out nearly 23 million prescriptions for Levothyroxine, making it the most popular medication to treat thyroid disease.

Most common causes of thyroid malfunction include autoimmune disorder, known as Hashimotos thyroiditis, which is 10 times more common in women than men. Another possible cause of low amounts of circulating thyroid hormones is thyroid cancer.

If you are taking Levothyroxine as your thyroid hormone replacement and suffering prolonged or excessive hair loss, it might be a side effect of these drugs on some people. When the thyroid hormone level is stable, hair grows back in normal rate. It seems to be common within the first month of treatment and more often in children than adults.

Radiation Treatment And Hair Loss

How often does letrozole cause hair loss $3.4 per tablet

Radiation therapy uses a high-energy beam to damage quickly growing cells in your body. The goal is to target cancer cells, but some normal cells get damaged as well.

Radiation only causes hair loss on the particular part of the body treated. If radiation is used to treat the breast, there is no hair loss on your head. But there might be loss of hair around the nipple, if you have hair there.

Radiation to the brain, used to treat breast cancer that has spread to the brain, can cause hair loss on your head. Depending on the dose of radiation, your hair may be patchier when it grows back or it may not grow back.

Possible Treatment Options For Etihl

For the purpose of preventing the ETIHL, reducing the rebound androgenic effects by maintaining the anti-estrogenic effect may theoretically act as a potential beneficial method for the hair follicle. To do so, combining the endocrine therapies with mitotane and ketoconazole which are used to disrupt the ovarian or adrenal androgenic hormones synthesis may provide this effect . However, some suppression therapies of adrenal glands functions, particularly ketoconazole, have various side-effects such as adrenal insufficiency and hepatic enzyme suppression .

In healthy adults, estrogen is known to play a key role in the hair development in tissue levels and also increase the amino acids and trace elements in hair texture . For this reason, trace elements and/or vitamin supplements may prevent the ETIHL. Moreover, one another important example to demonstrate the beneficial role of vitamins on hair health is that vitamin B6 is known to decrease the efficacy of the estrogen in hair texture or other tissues . Today, even though the opinion of that B6 supplements may be used to treat the baldness, this can theoretically reduce the estrogenic effects on the scalp, hence may not be effective in the management of ETIHL.

Folic acid is also reported to have a positive effect on hair health , however, unfortunately, there are some epidemiological studies that suggest folate may increase the tissue levels of estrogen, indicating that high levels of folic acid might lead to BC .

Those Most And Least Likely Drugs To Have This Side Effect Of Cancer Treatment

To many, hair loss is one of the more dreaded side effects of chemotherapy for cancer. An estimated 65% of patients undergoing classic chemotherapy experience what doctors call alopecia. But while some chemotherapy medications almost always result in such hair loss, others typically cause minimal hair loss.

Other factors related to chemo can affect hair loss as well, such as the dose of the drug given. Of course, effectively treating your cancer is the top priority. But knowing about this potential in advance can help you prepare for it. Fortunately, there are options available to help people cope with this symptom.
