The seven major nourishment and hair native common sense

Hair is what people who love beauty often pay attention to. Having a head of black and beautiful hair is a reflection of a person's health. All of us should pay attention to hair care and hair care in peacetime.

Let's take a look at what common sense is wrong in daily hair care? Everyone should pay attention in daily life!

1. Hair cannot be washed every day

Shampoo itself will cause a certain amount of hair loss, and the smoothness of the hair during the washing process is poor, which will pull the hair and cause mechanical damage. The scalp skin itself has a physiological regulation function. If the environment is dry, it will secrete more oil. If the environment is humid and hot, the oil secretion will be reduced. Excessive and frequent removal of oil is originally intended to keep the scalp dry, but washing it every day will make it Produce more oil.

Generally, in summer, it is enough to wash your hair every other day. If it is in winter, it is enough to wash your hair once or twice a week.

2. Adults lose 30-100 hairs per day, which is normal

Clinical hair loss is also standard. Under normal circumstances, it is normal for adults to lose 30 to 100 hairs per day. If you find that you are losing more hair than usual, and it lasts for more than 1 to 2 months, or your hair falls out in pieces, you need to pay attention.

3. White hair will not "pull out one and grow ten"

Hair grows from hair follicles, which are formed in the embryo. Generally speaking, pulling out hair will not have much impact on the hair follicles, so it is unscientific to say "Pull out one hair and grow ten hairs".

4. Silicone-free shampoo is just a hype concept

"No silicone oil, no irritation" has become a popular slogan. Are silicone-free shampoos really better than silicone-containing shampoos?

Yogi In fact, the merchants selling this type of shampoo first created a "misunderstanding", claiming that silicone oil will clog the hair follicles, causing dry and damaged hair, and even hair loss. Then call on consumers to choose "no silicone oil" shampoo. It is a bit wronged to push these responsibilities to silicone oil.

In fact, the so-called "silicone oil" is actually a chemical ingredient added to traditional shampoos that can make hair smooth-polydimethylsiloxane. Silicone oil is insoluble in water, and if it is not cleaned for a long time, it may cause blockage of scalp hair follicles. However, as long as you pay attention to clean your scalp every time you wash your hair, and try not to use the same shampoo for a long time, you can avoid this defect of silicone oil.

In fact, there are very few shampoos that can truly be free of silicone oil. Almost every shampoo has the ingredient "polydimethylsiloxane" in its ingredient list.

5 Shampoo with 2-in-1 wash and care, use less!

There are also shampoos on the market that claim to be all-in-one, but they are generally not recommended.

The pH value around the human hair is about 5.5. The shampoo and conditioner used in daily life adopt different pH formulas according to the pH value of the hair to maintain the acid-base balance of the hair.

Yogi shampoo is generally neutral or weakly alkaline, which is greater than the normal PH value around the hair. When the PH value rises, the cuticles will open, which is convenient for cleaning the dust and oil on the surface of the hair and in the gaps of the cuticles. The hair conditioner is generally weakly acidic, with a pH value between 4.5 and 5.0, so that the raised pH value of the hair will be restored to balance, and the cuticles will be tightened and closed.

The 2-in-1 product of cleansing and care has already neutralized the acidity and alkalinity, but in fact it can only play one role, usually to clean the hair.

6 anti-dandruff shampoo, can only wash away dandruff, can not prevent

Excessive dandruff is mainly related to the abnormal reproduction of fungi. Most of these fungi are distributed in areas rich in sebaceous glands. When the body's resistance decreases, it will lose its resistance to this fungus. Excessive increase in the number of fungi will lead to dandruff.

Now, the reason why most shampoos on the market can't really remove dandruff is because they are cosmetics in nature, and their basic function is only to clean and decontaminate, and they can't completely kill the microorganisms on the skin surface.

There are many reasons for Yogi's dandruff, some are the obvious manifestations of the metabolism of adolescents, and some are the manifestations of diseases, such as scalp pityriasis, psoriasis, seborrheic dermatitis and so on. Drugs must be used for specific diseases.

7 hair loss does not necessarily mean kidney deficiency

Kidney deficiency can indeed cause hair loss. But hair loss does not necessarily mean kidney deficiency. In addition to kidney deficiency, damp heat, blood deficiency, and liver depression can all lead to hair loss. From the perspective of Western medicine, mental factors, fungal infections, genetics, endocrine, etc. can all cause hair loss, and even shampoos and conditioners can also cause hair loss. The treatment for each type of hair loss is different. It is very irrational to invigorate the kidney for hair loss.
