[Soap Knowledge] How to properly use liquid soap to wash hair

Before getting to the main topic, let's first explain what washing hair means:

Washing hair = washing the scalp, not washing the hair.

First, let's briefly talk about the difference between the scalp and hair~

The scalp is living tissue:
Its main function is to isolate external pollution and prevent excessive evaporation of moisture from the skin outside the body. Like the skin on other parts of our body, there are problems such as oil production, keratin metabolism, and hair follicles getting clogged with oil and dirt. Therefore, you should clean it appropriately every day to keep your scalp healthy.

Hair is dead tissue:
Hair becomes greasy because the scalp produces sebum. The hair strands closer to the scalp have richer oil in the hair cuticles, so they are less likely to feel dry. On the contrary, the longer the hair, the closer to the end of the hair there is less oil. When the hair cuticles are not so moisturized, the hair at the end of the hair will feel dryer.

After distinguishing the scalp and hair, we can make a distinction after washing.

If your hair quality is normal, your hair is not too long, and you do less dyeing and ironing, your hair will basically not have major problems and will have fewer splits and dryness. But if at the same time you have greasy hair, hair loss, scalp problems, psoriasis, seborrheic dermatitis, etc., it is a scalp problem. The main function of liquid soap is to focus on the step of washing the scalp , using the principle of acid-base decontamination, so that the dead skin can naturally metabolize and become healthier.

1. Comb your hair first (if you have short hair, you can simply comb it) to remove surface dust. At the same time, shampooing will reduce dryness and tangles. (In fact, dryness and knotting are all caused by soap scum. Friends who are interested can read the next article)

2. Use plenty of warm water to rinse away most of the oil and dust from your scalp and hair.

3. Use shampoo to clean the scalp while massaging it with your fingertips. Do not use nails to avoid damaging the hair epidermis. *After first use, the foam will disappear quickly because there are still chemical residues on the hair and scalp.

4. After washing your scalp, rinse all the soap with plenty of warm water as quickly as possible. It is best to use a shower head for easy rinsing. Be careful not to use too hot water to avoid creating more soap scum and damaging your scalp.

5. After rinsing, you can spray wet hair with citric acid/white vinegar + water.

6. Use a towel to absorb some of the water/wrap your hair with a scarf and wait for 10 minutes, then blow dry with a hair dryer. After drying slowly, your hair will be easier to comb. The temperature of the hair dryer should not be too high. After drying the scalp, turn the temperature to a slightly cooler temperature and blow the hair to close the hair cuticles, making it less frizzy.
