Professional knowledge of beauty care

There are many beauty secrets that are very effective, but not many people know them. Including hair care, requires a lot of professional knowledge. Let me introduce you to the professional knowledge of hair care. Come and have a look!

Professional knowledge of hairdressing and nursing 1: Basic knowledge about hair

1. Introduction to hair: Hair belongs to a part of skin appendages (skin appendages include sebaceous glands, sweat glands, hair, nails and hair follicles).

2, hair classification: fetal hair: fetal hair is soft and light.

Hair pushing: thin, unmyelinated, distributed all over the body. Commonly known as "hair"

Terminal hair: thick, long and black, containing medulla. Like hair and eyebrows. Eyelashes, beards, armpit hair, etc.

3, the composition of hair: the part of hair exposed to the skin is called hair shaft.

The part inside the skin is called the hair root.

The part that wraps the hair root is called the hair follicle.

The part where the hair root and hair follicle fuse and swell is called hair bulb.

Hair structure: hair medulla, hair cortex and hair cuticle (commonly known as hair scales)

4. The main component of hair: it is composed of dead keratinocytes. That is, keratin is mainly composed of protein and 18 amino acids. Protein and amino acids provide nutrients for hair growth.

5. Hair growth cycle

Hair growth is periodic: growth period: hair is in growth period.

Degeneration: Hair stops growing.

Stagnation: Hair begins to fall off.

The length of hair in different parts is different because of different growth periods. For example, hair grows 0.27-0.4mm every day. The average is about 0.37 mm. The growth period is 3-6 years, the fading period is 3-4 weeks, and the dormancy period is 3-4 months. So the hair can grow to 50-60cm, and then fall off to regenerate new hair. The growth period of eyebrows is 6 months.

Hair loss is a normal physiological phenomenon. It is normal to lose 20- 100 hairs every day, and there will be an equal amount of new hair growth, so that people's hair will always maintain a certain amount.

Supplement: the color of hair is related to the melanin content in cortex and medulla (hair follicles are located at the basal layer of epidermis, and there are melanocytes in the basal layer, which secrete melanin particles, so we can see that different people have different hair colors)

Professional knowledge of beauty care II: Types and characteristics of hair quality

The type of hair is determined by the amount of sebum produced by the body. Sebaceous glands attach to the root of hair follicles and secrete sebum (sebum secreted by sebaceous glands can moisturize skin and hair).

1, oily hair: greasy hair. The second day after washing your hair, oil stains have appeared on the hair roots, and the scalp is piled up on the hair roots like thick scales, which is easy to itch. More common in people with fine hair. (Hair follicles are densely distributed per unit area, and there are more sebaceous glands, so there is more oil. )

2, dry hair: less oil. Hair is dry, dull and tangled. The scalp is easy to knot, loose and dry, and dandruff is easy to occur, and the hair tips are easy to split, so it is difficult to comb after soaking. The hair is stiff and has low elasticity (the hair with good elasticity can be extended by 20%-30% to restore its original length), and the elastic elongation is less than 25%. Causes of dry hair: insufficient sebum secretion or water shortage of hair keratin, frequent bleaching and dyeing, or overheated shampoo water temperature.

3, neutral hair: no oil, soft, smooth and shiny. The most ideal hair quality, Green Cicada is committed to making everyone neutral!

4, mixed hair quality: scalp oily but dry hair, relying on scalp hair oil within 1cm, dry hair tips or even split, more common in menstrual women and adolescents.

Hair Care Professional Knowledge 3: Hair Care

1, the correct shampoo time: once a week for dry hair, 3-5 days for oily hair and 5-7 days for neutral hair. Shampoo time varies from season to season.

2. Choice of shampoo: The scalp and hair of normal people are weakly acidic (ph4.5-5.5). If the shampoo with too strong alkalinity is used, it will destroy the acid-base balance between the head pi and the hair, which is conducive to the growth and reproduction of some harmful microorganisms, and will also lead to hair quality damage, and will also lead to excessive keratinization of scalp cells, resulting in scalp dryness, dandruff and hair embrittlement and bifurcation.

3. Correct shampoo method

Step 1: The temperature of shampoo is between 30 and 40 degrees Celsius. Before shampooing, wet your hair, then pour a proper amount of shampoo into your palm and rub it out with water. The dosage should not be too much, which is easy to stimulate the scalp to produce dandruff.

Step 2: Rub the hair and scalp evenly and gently with your fingertips for 3-5 minutes. Don't scratch your hair and scalp with your nails, which will easily damage your scalp and stimulate it to produce more oil.

Step 3: rinse must be clean!

Step 4: Dry the water drops on the hair slightly, then apply the conditioner evenly to the hair (scalp is forbidden), stay for about 15 minutes, and then rinse it off! Step 5: comb your hair. The choice of comb is very important. It is best to use boxwood comb or buffalo horn comb. Plastic dense tooth comb is easy to generate static electricity and pull hair, which is not suitable.

Additional: It is best to air dry your hair naturally after washing. If you need to use a hair dryer, please note that the maximum heat emitted by the hair dryer can reach 100 degrees Celsius, which is enough to destroy the hair quality and cause harm to the hair and scalp. Attention should be paid when blowing: the blowing mouth should be at a certain distance from the hair and scalp, and the heat should not be too high, and the residence time should not exceed 3 seconds (because the most basic component of hair is protein, and when the temperature exceeds 60 degrees, the protein of hair will be denatured).

Professional knowledge of hair care 4: common problems and analysis of hair

Hair is a part of the body, and hair problems are often not only reflected in appearance, but also related to the internal organs of the body. Traditional Chinese medicine believes that the kidney is the innate foundation, the source of qi and blood biochemistry, and the kidney dominates the bone and produces marrow, and the essence is vigorous. So there is a saying that hair is blood, so the quality of hair is closely related to qi and blood. In daily hair care, you can eat more black food, such as black beans, black sesame seeds, black fungus and black rice. It has the effect of tonifying kidney, solidifying hair and blackening hair!

1, alopecia

-alopecia areata: commonly known as "ghost shaving"

Etiology: autoimmune factors, mental factors (closely related) and genetic factors.
