Washing your hair early in the morning, especially between 3 and 10 am, can cause some problems. During this time, the pores on the scalp are often dilated, and washing your hair can interrupt the hair growth process and lead to hair loss. In addition, washing your hair early in the morning can also stimulate blood vessels, causing uncomfortable symptoms.
Should you wash your hair early in the morning?
People often avoid washing their hair at night because they believe it will affect their health. But you may not know that suddenly washing your hair early in the morning after waking up also stimulates blood vessels and causes discomfort.
The pores on the scalp usually begin to dilate between 3 am and 10 am. Therefore, washing your hair at this time can interrupt the hair growth process, causing hair loss.
In addition, the temperature in the morning is often quite low, so the risk of stroke while washing your hair is also higher. If you want to wash your hair in the morning, wake up 30 minutes earlier, wash with warm water, and dry your hair thoroughly afterward.
8 Times You Should Not Wash Your Hair
1. Do not wash your hair in the morning
After waking up, the body has not yet recovered its functions and blood circulation. Therefore, washing your hair in the morning can cause discomfort, even nausea and other dangerous conditions. The ideal time to wash your hair in the morning is 1 hour after waking up.
2. Do not wash your hair during menstruation
During their period, women’s bodies are often very sensitive and prone to illness, so taking care of the body at this time is very important. Frequent hair washing during the menstrual cycle can cause water retention. However, if you want to wash your hair, you can use shampoo and warm water to wash quickly. Then quickly dry your body and hair immediately after washing.
3. Do not wash your hair after drinking alcohol
When you have alcohol in your system, you should absolutely not bathe, whether in hot or cold water. Bathing after drinking alcohol will increase the feeling of intoxication, constrict blood vessels, and easily lead to colds, nausea, dizziness, and even ruptured blood vessels. Therefore, no matter how dirty your body is, you should only wipe yourself with a wet towel and go to sleep.
4. Do not wash your hair when you are too hungry or too full
We should also not wash our hair when we are too hungry or too full because doing so can cause digestive problems such as stomach upset, nausea, etc., and can slow down the digestion of food. Especially those with heart disease should absolutely not bathe at these times as it can easily worsen their condition due to localized lack of blood flow.
5. Do not wash your hair immediately after dinner
After dinner, the stomach is still full of food, and washing your hair immediately will affect the digestion and absorption of food. For those with heart problems, washing hair right after dinner can cause illnesses affecting the heart and brain. You need to be aware of this.
6. Do not wash your hair immediately after exercising
People tend to shower immediately after exercising because their bodies will smell. However, during exercise, a lot of sweat is secreted, and the body has just been exposed to sunlight, so washing your hair immediately can cause headaches and dizziness. Rest until your body feels dry, then start showering and washing your hair; it’s not too late.
7. Do not wash your hair late at night
Washing your hair late at night is a cause of headaches. After washing your hair, if you don’t dry it thoroughly and go to sleep with damp hair, it will obstruct blood circulation, leading to prolonged headaches. Therefore, people often tell each other not to wash their hair late at night to avoid chronic headaches that are very difficult to treat.
8. Do not wash your hair when you have a fever
When you have a fever, your body is in its weakest and most sensitive state, and any impact will lead to increased pain. Therefore, it is very dangerous for your body to bathe or wash your hair when you are sick, as it can easily lead to a worse cold and seriously affect your health.
The Ideal Time of Day to Wash Your Hair?
Actually, the ideal time of day to wash our hair is from 10 am to before 4 pm. The temperature is high at this time, which is very suitable for washing hair. However, if you can’t wash your hair during these hours, you can wash it in the evening (before 8 pm).

How Many Times a Week Should You Wash Your Hair?
Oily Hair
People often wash their hair multiple times when it’s oily, but this is not recommended at all; it can even lead to hair becoming stickier and oilier. If you have oily hair, wash it every 2 days and no more than 4 times a week. This is a way to keep your hair cleaner without altering other endocrine activities of the scalp.
Dry Hair
Dry hair is hair that has been damaged by chemicals we have used for styling. Therefore, you should only wash your hair every 4 days to avoid further damage. Washing your hair too often, once a day, will make your hair weaker and your scalp drier. In addition, you should also use conditioner (such as Pantene conditioner) and air dry your hair instead of using a hairdryer so that your hair is not dry, frizzy, and prone to split ends.

Normal Hair
If your hair is normal, neither oily nor dry, you only need to wash it 1-2 times/week. Cleaning the scalp and hair by washing should be done reasonably. Washing your hair too often only makes it sticky and produces more dandruff and itching, and can even lead to hair loss.
How Many Times a Week Should Men Wash Their Hair?
Men should only wash their hair twice a week, which is the most reasonable. In some cases where you have to wash your hair frequently, you can wash it with water and add a little lemon juice. Maintaining this habit regularly will help you have strong and healthy hair.

Things to Keep in Mind When Washing Your Hair
Do not use your fingernails to scrub your scalp when washing
People often have the habit of using their fingernails to scrub their scalp vigorously with the aim of making their hair cleaner. There are a lot of bacteria present in our fingernails, and the scalp is very thin and easily scratched, so rubbing too hard can damage and infect the scalp. When washing, use your fingertips to gently massage your scalp and hair to remove dirt instead of your fingernails.
Avoid pouring shampoo directly onto your scalp
The shampoo we use often contains a lot of chemicals, so when using shampoo, you should immediately stop pouring it directly onto your hair and scalp. This can cause chemicals to concentrate where you pour the shampoo and harm your scalp, and your hair will not be completely clean.
Do not brush your hair when it is wet
When your hair is wet, any strong impact can damage it and lead to breakage and hair loss. Therefore, protect your hair by gently patting it with a dry towel until it is dry, then brush it.
Dry your hair before going to bed
Going to bed with wet hair is completely harmful to both your hair and your health. Hair is weakest when wet, so not drying it before sleeping will make it more prone to breakage and dryness. Besides, sleeping with wet hair also makes us more susceptible to colds, bacteria can quickly develop, and more dandruff will appear on the scalp. Remember not to sleep with wet hair.
Do not wash your hair every day
Washing your hair too often, every day, can make it damaged, brittle, and prone to breakage. When the moisturizing oils are lost due to frequent washing, the scalp becomes dry, flaky, and itchy.
Brush your hair before washing to limit breakage
Brushing and detangling your hair before washing is essential. When hair is wet, it is difficult to untangle knots, which can easily lead to breakage and hair loss. You should divide your hair into sections and brush from the ends first. Also, those with permed or chemically treated hair should use a wide-tooth comb.

Wash your hair with warm water
Washing your hair with warm water around 40-45 degrees Celsius will dilate the pores and epidermal layers, helping you remove dirt on the scalp most effectively.
Choose a shampoo that suits your hair
Everyone’s scalp and hair type are different, and you need to choose the right shampoo to keep your hair shiny and smooth. Choosing the wrong shampoo for a long time can lead to risks such as dandruff, hair loss, or scalp irritation, significantly affecting your appearance and confidence.
Wash your hair twice
Washing your hair twice with shampoo can help thicken hair, make it completely clean, and make it more voluminous. That’s also why at salons, they often wash your hair twice.
Gently towel dry before blow drying
After washing and towel-drying your hair to about 60% dry, use a tissue to absorb moisture in areas such as the hairline, nape, ears, and ends. When your hair is almost completely dry, you will shorten the time it is exposed to heat from the dryer.
