Chemicals In Water Can Cause Hair Loss

Hair loss, or alopecia, can be a side effect of toxic chemicals and metals that are commonly found in the water supply.


Not only chemicals from shampoos and conditioners are harmful for your hair but the water that you use everyday to shower with contains chemicals as well.

There are several water contaminants that can cause hair loss. One is selenium, which is an element found in other ores. Most commonly, this element gets into the water system from run-off from petroleum refineries and from mine discharge. However, this element is also found in compounds that make photocopier equipment. According the Environmental Protection Agency (EPA), the best way to remove this element is by a reverse osmosis water filter.

A good water filtration system installed in your home is the only way to proactively monitor and ensure the quality and safety of your drinking water. Reverse osmosis water purification systems can remove 90-99% of all contaminants from city and well water to deliver healthy drinking water for you and your family.

So, to keep your head of hair thick and healthy, be sure to be washing it with the purest water possible. And in the meantime, you could also be protecting yourself from serious disease!

Common contaminants found in water that can contribute to hair loss are:

1. Copper

Studies show that the amount of copper in your body has a direct relationship to how much hair you have on your head. Too much copper means too little hair.

While balding is genetic in men, the rate of hair loss is controlled by the copper level.

The metal copper controls hair growth and hair loss. Healthy tissue concentrations of copper lie between 1.7 and 3.5 milligrams. Everything else will cause hair loss. You can have too little copper (below 1.7 milligrams) or too much copper (above 3.5 milligrams) and the same thing will happen: your hair will start falling out.

Copper imbalances can affect the liver, nervous system, reproductive system and connective tissue including the hair, skin and nails. Having too much copper in the body can cause hair to fall out. Too much iron or zinc in the body decreases copper absorption and can lead to copper deficiency.

The primary culprit in water is the copper pipes through which you get your drinking water.

If you live in an older home, you might have copper pipes, which means your tap water may contain copper. Switching to bottled water or having a filter on your faucet may have an impact on stopping hair loss.

2. Chlorine

If you live in an area that has a high chlorine content in the water then purchasing a filter for your shower head to block the chlorine is an absolute must.

Many people are not aware that chlorine could affect their hair. Chlorine is very damaging to hair.

Most people think of chlorine as an ingredient that is only found in swimming pools. Chlorine is also found inside the home and is used by municipal water suppliers to purify and disinfect tap water. Individuals that are concerned about chlorine in their home can purchase water filters that can be used on faucets and showerheads.


Chlorine is extremely harmful for the health of your scalp and locks. Regular exposure to chlorine can trigger accumulation of sebum, or natural scalp oil that nourishes and lubricates the hair shafts, inside your hair roots, causing clogging and possible inflammation.

Chlorine bonds to the hair, stripping hair of the oils that are there naturally to protect and nourish our hair. This can cause the hair to become dry, frizzy or brittle. Chlorine in excess has also been shown to cause damage to the hair follicles and increases the risk of hair breakage. The more hair is exposed to chlorine, the more that damage becomes a possibility because of the exposure.

Chlorine in swimming pools

Large amounts of chlorine are used in swimming pools to kill bacteria and fungus, keeping the water sanitary for people using the pool. This prevents viruses, infections and the like from being passed from swimmer to swimmer. As a result, your hair is exposed to chlorine more in a swimming pool than anywhere else. Chlorine exposure to other water sources is so minimal, damage from it is unlikely. This is what gives swimming pools their bad reputation of being hard on a person’s hair.

If you swim every now and then it’s no big deal, but for a daily swimmer it can be an issue. The chlorine dries out your hair which can cause breakage. It’s not a permanent thing though, if you stop swimming in it, any new hair growth will come in healthy.

You can minimize chlorine damage by using shampoos and conditioners that remove chlorine. Regular shampoos are not formulated to release chlorine from the hair, which is why special shampoos are necessary.

If you are continuously exposed to iodine leeching agents like fluoride and chlorine, then your thyroid will not work. Fluoride is in the water supply. Chlorine is found in thousands of chemicals and swimming pools.

Showering with hot water  that contains chlorine causes the chlorine to be sucked into your pores and a gas to be released that is sucked into the lungs and bloodstream faster than you could ever drink it. Chlorine and fluoride are endocrine/metabolic destroyers of our bodies and kill the thyroid and pancreas islet cells slowly but surely.

Fluoride and chlorine displace iodine from the body. The chemicals (called halides) kick out iodine from chemical reactions leaving your body devoid of iodine and without iodine your thyroid gland becomes useless!

3. Fluoride

Today, many people living in fluoridated communities are ingesting doses of fluoride (1.6-6.6 mg/day) that fall within the range of doses (2 to 10 mg/day) once used by doctors to reduce thyroid activity in hyperthyroid patients. This is of particular concern considering the widespread problem of hypothyroidism (under-active thyroid) in the United States.

Both an overactive thyroid and an under-active thyroid can cause hair loss. Hormonal problems may cause hair loss. If your thyroid gland is overactive or underactive, your hair may fall out.

One 2010 study by Zheng-hui Wang and colleagues from the Second Hospital in China shows there may be a correlation between hair follicle damage and fluoride. The exact way the excess fluoride effects the hair follicle is unclear, but damage will result in hair loss. According to Medical News Today, some scientists and interest groups have shown concern about the continued application of fluoride to the water systems, deeming the application unnecessary and less useful than previously thought.

Fluoride poisoning produces hair loss by affecting the thyroid. Fluoride slows down the thyroid function which leads to Hypothyroidism – Underactive Thyroid.

This becomes a real problem if your water supply happens to be fluoridated as well.  Fluoride also interferes with iodine and produces hypothyroidism which can also contribute to hair loss. Hypothyroidism (underactive thyroid) is notoriously high among the British for that very reason; they are heavy tea drinkers. Tea also interferes with the absorption of iron, and low iron levels are an often overlooked cause of hair loss, particularly in young men.


Get off chlorinated and fluoridated water. Start drinking mineral water or de-chlorinated de-fluoridated filtered water (you will need a reverse osmosis filter if your water has fluoride in it.)

A good water filtration system installed in your home is the only way to proactively monitor and ensure the quality and safety of your drinking water. Reverse osmosis water purification systems can remove 90-99% of all contaminants from city and well water to deliver healthy drinking water for you and your family.
