Hair can be washed every day? How to choose shampoo? After washing hair must be blow-dried? Let the doctor help you answer these questions about hair washing in daily life.
Myth 1. Don’t dare to wash your hair every day
I believe many people have heard the saying “you can’t wash your hair every day”, for example, washing your hair every day is easy to lose hair, or washing your hair every day will make your scalp more and more oily. In fact, these views are wrong.
The normal amount of hair fall per person per day is between 50 and 100, and it is easier to lose hair when washing or combing hair. If you wash your hair every day, the amount of hair loss in a single session must be less than the amount of hair loss in a single session if you wash your hair once every three days. No matter how many days you wash your hair, as long as the ratio is in line with the normal daily hair fall, it is fine.
On the other hand, your scalp will not get greasier because you wash it every day, unless you over-apply hair oil, or have a poor lifestyle and diet.
The need to wash your hair every day is not only related to your personal habits, but also to the amount of oil on your scalp and how dirty your hair is that day.
People who are prone to oil on the scalp can wash their hair once every 1 to 2 days to avoid too much oil, making the hair flat and affecting the appearance of styling, and also to avoid blocking the pores due to oil that can easily lead to folliculitis.
People who do not have a lot of oil on their scalp, such as elders or young children, do not necessarily need to wash their hair every day if they are not going to a dirty or dusty environment that day, or if they are not sweating a lot.
A reminder: If you find abnormal hair loss, it is recommended that you keep a hair loss diary to record the daily hair loss for your dermatologist’s reference. The physician will take a medical history with hair pulling test, dermatoscopy or blood sampling, and in some cases, even further biopsy to determine if there is abnormal hair fall and further prescribe the right medication.
If the scalp or hair condition is caused by daily shampooing, it is recommended that you first go to a dermatologist and check if you have the following conditions：
● Scratch your scalp hard with your nails instead of massaging it with your fingers when washing your hair.
● Shampoo is not suitable for you, such as too strong.
● Using a moisturizer or conditioner without avoiding the scalp, or not rinsing well after use.
● When rinsing hair, the water temperature is too high; when blow-drying hair, the hair dryer temperature is too high.
● Excessive application of hair oil and hair styling products.
● Recently staying up late, sleeping late or being stressed. Eating spicy and stimulating or fried food often.
Myth 2. Shampoo to change often
The general direction of choosing shampoo is based on mildness, simple ingredients, and no excessive additives.
There is a saying that the brand of shampoo should be changed often. In fact, if you feel comfortable after using the selected shampoo, you can continue to use it and do not necessarily need to change it. Unless it is a special medicinal shampoo, it needs to be used according to the physician’s instructions, and long-term washing is not recommended.
There are different shampoos for different scalp types.
Healthy scalp: Just choose a mild product and cleanse moderately.
Oily scalp: For people with oily scalp, it is recommended to pick a shampoo with a clear texture and not to use a hair conditioner with oil ingredients or a wash and rinse product. Otherwise, it may cause the accumulation of oil, after washing, the hair as flat collapse. In addition, if you shampoo your hair too many times or use a shampoo with too much washing power in order to wash out the grease, it may cause dryness and easy breakage.
Dry scalp: Shampoo is mainly mild, avoid using shampoo products with too strong decontamination or oil removal power.
Diseased scalp: For example, if you have seborrheic dermatitis. When the scalp is often repeatedly inflamed, it is best to choose a simple and mild shampoo, and under the direction of a physician, a shampoo with medicinal properties or with anti-allergy and soothing ingredients.
It is important to note that using special drug-containing shampoos too often can lead to resistance problems. Steroid-containing shampoos are also not suitable for long-term use, otherwise they may become sensitive scalp or produce steroid-related side effects. It is recommended to consult a dermatologist before using such medicated shampoos.
Myth 3. After washing hair without a hair dryer blow dry, worried about hurting hair
Some people wash their hair and then just use a towel to wipe it off, or go straight to bed without blow-drying. Although more convenient, but there are health concerns.
Chinese medicine practitioner Li Ailing pointed out that whether blow-drying or drying, “we must avoid dampness to stay in the scalp for a long time, in order to maintain health”. She explained that if dampness stays in the skin for a long time, it is easy to cause heavy head sleep, headaches, stiffness and soreness of the shoulders and neck and other “dampness and muscular surface” of the disease, which leads to low sleep quality, repeated pillow conditions.
Especially patients with nose allergies and cold body, more blow-dry hair. Because “the head is the meeting of all the yang”, the body’s twelve meridians, six Yang meridians are circulating head, head dampness is easy to circulate along the meridians, affecting other parts of the body. Therefore, if you do not blow dry the scalp for a long time, it is easy to aggravate the symptoms of nasal allergies, but also make the physique into a more complex cold damp physique. These patients use hair dryer to dry their hair, can remove dampness and dispel cold, two birds with one stone.
In addition, some people feel that blowing hair with a hair dryer is easy to hurt hair, as long as you pay attention to 4 points, you can avoid：
1.dry the hair first before blowing, because wet hair needs to blow longer, easy to make the hair injury due to heat accumulation.
2.Do not set the temperature of the hair dryer too high, so as not to hurt the hair and stimulate the scalp.
3.Avoid hair dryer too close to the scalp, the hair dryer should be 15cm away from the hair.
4.when blowing hair, should be evenly blowing back and forth in all areas of the head, avoiding a fixed point blowing.
An experiment found that the hair dryer if fixed blowing the same place for about 10 seconds, it will heat up more than 70 ℃, causing significant damage to the scalp. Therefore, a safe distance of 15 centimeters should be maintained, and always move the blowing part. Because, when the scalp overheating injury, may be oily, itchy, hair quality will also be damaged.
