Does Showering at Night Cause Hair Loss?

Does Showering at Night Cause Hair Loss?

I have heard that showering at night can cause common cold, sore throat, fever and surprisingly hair loss too.

Therefore I wanted to find out whether there is any truth to this or whether it’s a big fat myth. I went on seeking information regarding this but could not find any solid research studies to support this theory. 

Does showering at night cause hair loss? Showering at night DOES NOT cause hair loss. But going to bed with wet hair can cause dandruff and hair tangling which could lead to hair damages and hair breakages.

In this article I will discuss the information that I have gathered on how showering at night could cause hair loss and what you can do about it.

Why is showering at night bad?

There is no clear evidence and research studies done to prove that showering at night could lead to hair loss. However the expert opinion is that showering at night is not the real culprit, but going to the bed with wet hair is.

So how can going to bed with wet hair cause hair breakage and damage? There are two possible scenarios.

1. Wet hair could get tangled in the sleep

As much as the dry hair, the wet hair can also be very weak. This is the reason why you should not wipe the hair hard or comb the hair hard if your hair is wet, especially if you have long hair.

When you sleep, you twist and turn every way that you feel comfortable. This makes the hair rub against the pillow, which increases the friction between the pillow and the hair. Due to the weak nature of the wet hair, this friction could cause hair breakage.

Further when the hair is wet it becomes smooth. However when you rub the wet hair on the pillow case, the hair will be twisted and also the pillow case would absorb the water from the hair. 

Therefore the hair will be dried off but still keeping the hair twisted. So when you wake up the next morning, the hair will be tangled. When you try to comb the tangled hair, it could cause hair damages and hair breakages.

2. Wet hair is ideal for dandruff

The researchers have been trying to find the reason which causes dandruff, but it still remains an unsolved mystery. However there is a common belief that dandruff is caused due to a nutritional deficiency, a bacterial function or a fungal influence.

The studies indicate that dandruff itself is not a fungus but it is caused by a fungus called Malassezia [1]. Fungus grow and are highly active in moist warm places.

So when you go to bed with wet hair the pillow case will also become damp. This moisture and the warmth between the hair and the pillow case could be an ideal breeding space for fungus.

When the dandruff spreads due to the activity of the fungus, the hair will be itchy and it can even cause scalp infections. Constant scratching to get rid of itchiness could damage the hair strands and follicles.

Further scalp infections can affect the health of the scalp which can affect the health of the hair.

The studies further states that Malassezia feeds on the sebum in our scalp. Sebum is an oil produced by the sebaceous gland in order to moisturize the hair and to protect the scalp.

The fungus feeds on sebum, and the flakes of this oil falls off as dandruff. The body keeps on producing this sebum, but it could take a couple of days. Until such time the hair could become dry due to the lack of oil.

Therefore the hair will be dry and weak which could break off easily.

What to consider before showering at night

Before taking the next shower at night please do consider these factors and make your decision.

1. Do you have enough time to dry off naturally

This is highly important for a person with long hair. It takes time to dry off the hair naturally if the hair is too long. On average it could take about 2 hours to dry out a long hair.

Therefore if you are planning to take a shower at night, make sure that you have enough time to allow the hair to dry up naturally.

2. Is it absolutely necessary to shower at night

As per my opinion, showering in the morning is the best. It would be refreshing and healthier than showering at night.

If you are showering at night, just because it is convenient and saves time then you have to think once again. How much time do you take to shower? Maximum 20 minutes? Just try to manage your time in the morning to include your shower routine also.

If you work a blue collar job or an athlete who sweats during the day time or at least wearing hair gel, then having a shower at night would be ok. 

3. Are you showering hot water

It’s the night and the water is cold. You might be tempted to shower hot water even if you are living in a tropical country. Hot water can be bad and damage your hair.

If you are showering hot water, then make sure that you are not showering every single day. And keep your showers for a maximum of 10 minutes. Check out the above link which leads to a previous article of mine, so that you can have an in-depth understanding about how hot water showers could damage your hair.

4. Did you shower in the morning or planning to shower next morning

The dermatologists suggest that showering once a day is absolutely enough for an average person. Therefore if you have already showered in the morning, showering at night also can be too much. Too much showering can wash away the natural oils in your hair.

If you know that you are going to take a shower at night make sure to skip showering in the morning. 

If you are planning to shower next morning, then think whether you could hold the night shower until the next morning. 

What if there is no time to dry the hair before hitting bed?

Due to the busy schedules that we go through every day, there might be situations where you would have to shower at night without having enough to allow the hair to dry off naturally. In such situations, follow these instructions to keep your hair healthy.

1. After the shower run your fingers down the hair and gently squeeze any extra water in the hair. Then gently pat your hair with a clean dry towel. If it still feels wet, then follow the next step or point the hair to a fan which is on low speed and gently comb the hair so that it does not get tangled. 

2. You can use a hair dryer to dry your hair off before going to bed. I’m not a fan of hair dryers. They could dry up your scalp. Therefore it is important to keep the hair dryer at medium heat and not too close to the scalp. Do not keep the dryer focused on a particular single spot. Instead move the dryer up and down along the hair strands

3. If you have long hair, make sure to comb the hair properly and get it to a ponytail before hitting the bed. Make sure the ponytail is not too tight, making it difficult for air to get inside to dry the hair out overnight. Getting the hair to a ponytail would also minimize hair tangling.

4. Make sure to sleep on your back, to avoid any tangling of the hair. Sleeping on the side can cause the hair to tangle, which leads to hair breakage.

5. Make sure to change the pillow cases often, and put the pillow to dry out in the sun on the next day after going to bed with wet hair. This will avoid any fungus and bacteria growing on your moist pillow case, which can lead to dandruff and other infections.

Conclusion

Showering at night does not cause hair loss, but going to bed with wet hair could damage your hair which could lead to hair breakage.

This is a problem faced by the men and women with long hair due to the time that it takes to dry out their hair completely. If you have short hair, then this would not be much of a problem. However, do not shower for more than once a day, unless it is absolutely necessary.

If you know that you are going to take a shower later that day, then make a plan to have the shower at a convenient time which gives enough time to dry the hair completely.
