Now there are a lot of silicone-free shampoos on the market, so that the silicon-containing shampoo is put into the "cold palace", then the problem is coming. Is the silicone-containing shampoo that we used before really cause hair loss?
Rumors: Silicone oil shampoo can cause hair loss.
Source: Buying care products today, many people will recommend you to use silicone-free oil care products, and said that silicone-free shampoo products do not block hair follicles, can effectively reduce hair loss, and good for anti-dandruff and oil control. To this end, a variety of silicone-free shampoos are full of WeChat friends, although the price is 5 to 10 times the price of ordinary shampoo, but still highly sought after.
Truth: Liu Yong, deputy director of the Department of Dermatology, Shanxi Grand Hospital, said that the silicone oil component contained in the care products is polydimethylsiloxane, which is generally considered to be inert and non-toxic, and silicone oil is a macromolecular substance. It will not be absorbed by the hair follicles, and it can play a moisturizing and smoothing effect. It will not affect the body within the normal range, and will not cause clogging and hair loss of the scalp hair follicles.
According to Liu Yong, the main component of hair is keratin. There are many uneven scales on each hair. After the hair is thoroughly cleaned, the scales are opened. If there are damaged scales, it will increase the friction between the hairs. In the later combing, it will increase the difficulty, thus increasing the damage of the scales. After shampooing with shampoo containing silicone oil, the silicone oil adheres to the gaps in the scales, filling the surface of the hair and making the hair feel supple. There is not much silicone oil in the silicone oil shampoo. Under the cleaning effect of the surfactant, a large amount of water is washed, and it will not remain on the scalp. Now there are new ingredients for the improvement of silicone oil structure, such as ether formation or amino group addition. These new elements have stronger ability to bind hair to silicone oil and are more water soluble. (Popular China)
Xiaobian has something to say:
First of all, the most important thing is that we have to figure out the health of our hair and scalp, to understand the shampoo that our hair needs, and then we choose shampoo. In the supermarket, shampoo inside the hair salon, many shampoos only write some selling points, and many things are not expressed to consumers, so we have been trying one after another shampoo, it is difficult to find the right one. Really find a suitable one, it won't take long, it may not work.
So how do we judge our hair?
Generally divided into four categories of oily, neutral, dry, and mixed. In addition to neutral hair, oily hair always causes discomfort, such as dandruff, itching, greasy feeling; dry hair is mostly sensory problems, such as hair ends, dry, when dry, The hair is dull.
Oily hair: After washing the hair, there are more oil and dandruff. After blowing the hair, it is easy to deform, and the oil is bright, the hair is thinner and more fragile, although more sebum can protect the hair, so that Hair is not easy to crack, but the total area of sebum covered by relatively thin hair is relatively small, so the sebum is oversupply, the water is less than oil, and the hair is oily. The sebaceous glands of the head are very rich, so the oil secreted by the head is also very strong.
Neutral hair: smooth and shiny, not greasy, not dry, easy to shape, this is healthy and normal hair, water and oil are moderate, there may be a small amount of dandruff.
Dry hair: less sebum secretion, hair is thick, stiff and inelastic, dull and dull, hair roots tend to curl, hair splits or tangles into a mass, easy to break, split and interrupt, sun exposure, madness Blowing, air drying, etc., can absorb and damage the oil on the hair and lose moisture, resulting in hair dryness and damage, too little oil and water. Dyed, burned and damaged hair should also belong to the dry hair. In the process of dyeing and ironing, under the condition of strong alkali, opening the hair structure or cutting the hair disulfide bond will cause some structures of the hair to be destroyed and lose the lock. Water capacity.
Mixed hair: scalp oil but dry hair, is a kind of oil that is close to the scalp and has a lot of oil in the hair, and the more the hair is dry or even the mixed state. Women who are in menstruation and adolescents are mostly mixed hair. At this time, the hair is in the best condition, and the hormone level in the body is unstable, so there is a phenomenon of oily and dry coexistence. In addition, excessive perm or hair dyeing, and improper care, can also cause hair dry but scalp still greasy hair.
Supplementary note: There are dandruffs that do not belong to the hair quality category and belong to the scalp category. There are four main reasons: caused by pathological changes in the scalp, due to scalp scalp detachment, due to excessive secretion of scalp oil, due to microbial growth of the scalp.
Choose your own shampoo for different hair types
Oily hair: neutral, slightly alkaline cleansing shampoo. With the addition of anti-dandruff agents (ketoconazole, OCT, etc.) due to dandruff caused by bacterial growth, it is better than ZPT (since ZPT system usually contains oil).
Neutral hair: Neutral, slightly acidic shampoo, with simple care ingredients.
Dry hair: slightly acidic, weakly acidic with care ingredients shampoo, with conditioner, or often oil.
Mixed hair: clean first, then care. First, treat with oily hair, then apply hair conditioner with hair and avoid contact with the scalp.
