Water affects humans in many ways. The most significant way is through direct consumption. Just like direct consumption, there are various ways to affect humans through indirect consumption. 

Hair washing is such as a crucial indirect consumption that could bring healthy or unhealthy impacts to humans. Although there are several ways to measure the impact that could happen to hair through washing, the TDS of water is the most trusted way.

In this article, we will inform you about choosing the TDS of water for hair wash and more things you should know.

What does it mean by TDS of water for hair wash?

The TDS level of water is considered as the amount of magnesium, silica, and calcium-like minerals in the water. Lead is also accountable, which is not usually available in drinking or bathing water.

If the TDS of water is high, then that will not be good for humans.

What is the optimum TDS of water for hair wash?

The recommended TDS of water for hair washing is 350 TDS – 500 TDS. That can be as low as 300 TDS, as there will not be any outcome related to hair loss.

That can be as high as 1000 TDS if you use shampoos or softening soaps to soften water.

TDS Value (mg/L)Side Effects
Below 150Hair can become excessively dry and brittle
150 – 250Suitable for those with dry hair
350 – 500Suitable for those with normal hair
250 – 350Suitable for those with oily hair
Above 750Hair can become greasy and heavy

Note: But, it is not advised.

What happens if you choose high TDS of water for hair wash?

There are several outcomes you may get due to taking high TDS of water for hair wash.

Hair Fall

The most significant outcome is hair fall. Research has proven that the high TDS of water may cause hair fall. If the TDS of water is high in water, it means more minerals may damage hair follicles.

Hair Skin Diseases

The high amount of miners in water may also cause skin itching and create wounds in the end. Research has found that even eczema is a possibility due to the use of high TDS water for hair washing.

Hair Discoloration and whitening

Hair discolouration is also an outcome due to washing hair with high TDS of water. Minerals in water would cause oxidation, and hair is one of the most susceptible parts of the human body. As a result of this, hair browning, whitening, and multi-colouration would happen.

Pipe Clogging

When you use high TDS of water for bathing, there can be clogging as well since the minerals in the water may deposit in the pipes and small pipelines. You will not be able to get a bath on time due to this.

What happens due to low TDS of hair for hair wash?

You will not have to face any effect on hair due to having low TDS of water for bathing. But, it is advised to stay in the 500 TDS. The reason is that the low TDS of water may be more soluble than the recommended TDS of water.

How often should I replace the battery in my Zero Water TDS Meter?

The frequency of zero water tds meter battery replacement depends on your usage and the type of batteries you use. However, it is recommended to replace the battery once every 6-12 months. Regularly changing the zero water TDS meter battery ensures accurate readings and uninterrupted use of the device.

Does direct consumption (drinking) of low TDS of water cause hair fall?

Yes. It has been found that there can be hair loss as an outcome due to direct consumption (drinking) of high TDS of water.

The WHO recommends drinking 250< TDS <350mg/L water to have a healthy body. Undoubtedly, that will bring healthy hair.

Since the solvent quality of low TDS of water is higher than the recommended level, there can be side effects in the body. Hair loss is one of them.


Having various TDS of water for hair washing is not the thing you should do, but stick to the optimum TDS level of water, 500 TDS. Although you may lower the TDS value, you must not exceed that at all.
