What ingredients in shampoo can cause hair loss?

Silicone oil and lauryl alcohol, shampoo and antiseptic shampoo can all cause hair loss. It is taboo to add these ingredients to shampoo. Their addition will not only aggravate scalp irritation, but also aggravate hair loss.

Hair loss is a very confusing thing for many people now, so there are many reasons. What ingredients of shampoo can cause hair loss? Next, let Bian Xiao of her time give you a detailed answer. Interested friends come and learn about the situation.

What ingredients in shampoo can cause hair loss?

1. Sulfate surfactants There are three most common surfactants in care products: soap base, sulfate (SLS/SLES) and amino acids. Little fairies who love skin care know that soap-based cleansing is strong and easy to dry and tighten after washing. Amino acids are mild and non-irritating on the surface, and everyone prefers amino acid cleansing. In terms of shampoo, SLS/SLES is the mainstream surfactant of daily chemical products on the market at present, and sulfate can be seen in old shampoos such as Head & Shoulders Rejoice. Sulfate has strong surface activity and abundant foam. Although it has certain irritation, it can reduce irritation and side effects through the combination of ingredients. In order to ensure the cleanliness of shampoo, some high-end brands often add common amino acid surfactants and mild amphoteric surfactants such as coconut betaine while retaining SLS/SLES.

2. Silicone oil silicone oil, an inconspicuous softener added to shampoo, suddenly became the chief culprit of hair loss. There are many reasons for hair loss, so you can't simply and rudely throw the pot of hair loss to it. In fact, the content of silicone oil in shampoo is very small. Silicone oil is a macromolecular substance and will not be absorbed by hair follicles. As a softener with stable properties, it can also effectively solve the problem of dry and knotted hair. Recently, I saw many girls with dry and forked hair wearing silicone-free shampoo crazily. The more they washed, the drier they dried, and their hair was combed to the ground. It really hurts!

3. dioxane says that when everyone shouts dioxane, they have to mention SLES just mentioned. Dioxane is not a deliberately added ingredient in shampoo, but a by-product that will remain in SLES raw materials. Wang Ba shampoo, which once dominated the hair loss market, became cancer-causing shampoo because dioxane was hacked. Regardless of dosage, talking about ingredients is hooliganism! According to the research results of relevant institutions under the Australian National Occupational Health and Safety Committee, the ideal limit of dioxane in daily consumer goods is 30ppm, and the upper limit of toxicology is 100ppm.

4. Methyl isothiazolinone Methyl isothiazolinone (MIT) is an efficient bactericide and a heat-resistant aqueous preservative, which has a good effect on inhibiting the growth of microorganisms, and is often used in cosmetics, personal care products, shampoos and shower gels. At present, there is sufficient evidence to prove that the use of stay cosmetics containing MIT (including cosmetic wipes) is related to contact allergy and allergic contact dermatitis. At present, the EU has banned the use of MIT in stay products, and recently reduced the use concentration of MIT in rinse products. Long-term use of products containing MIT may cause itching, redness and urticaria. It may also induce contact dermatitis. Scalp health is the key to anti-shedding, and everyone should try to avoid this ingredient when choosing shampoo.

How to choose healthy and safe shampoo

1. Shampoos containing nonionic surfactants, nonionic surfactants and natural detergents extracted from coconut have better effects than amino acid shampoos, S-type shampoos and soap-based shampoos. It is the most respected and recognized detergent in this century. Often this shampoo is more expensive than the shampoo on the market, because nonionic surfactants are more expensive. At present, it mainly consumes abroad, or middle and high-end consumer groups.

2, choose organic natural plant shampoo, this kind of shampoo is more powerful, and the organic products certified by strict organic certification bodies are very authoritative! Strictly add more than 95% organic certified plant ingredients, and the rest can be natural. Preservatives and surfactants are both components in organic products, but the requirements of organic cosmetics are more stringent. They are from plants, not chemically synthesized.

What should I do to prevent hair loss?

1, moderate drinking. Liquor, especially hot liquor, can cause scalp fever and moisture, leading to hair loss. Even beer and wine should be drunk in moderation, at least two days a week, so that the liver can rest. 2, eat more protein food, the human body must have enough protein to ensure the healthy growth of hair, if the lack of protein in the body will lead to hair loss. So I suggest you eat more beef and eggs, but Polygonum multiflorum Thunb, animal liver, black sesame seeds, black beans and so on. Some traditional Chinese medicines also have a good effect of tonifying kidney and preventing hair loss.

2. Supplement vitamin C and iron. Iron deficiency will lower the level of red blood cells and cause hair loss. Red blood cells play a vital role in the health of hair follicles. Taking some iron dietary supplements and vitamin C (vitamin C helps iron absorption) can prevent hair from falling off, which is also a cheap and practical method.

3. Cleaning and repairing. When shampooing, use a shampoo with mild cleaning and soothing effects to achieve the cleaning effect. Use scalp essence to promote capillary activation of hair follicles after shampooing.

4. Pay attention to adequate sleep. Because of the high temperature in summer, people's rest at night is not as good as that in other seasons, and they can't ensure adequate sleep, which will lead to low immunity and resistance of human body throughout summer. Long-term lack of sleep can easily lead to negative emotions such as nervousness, depression, fear, etc., so that autonomic nerves are disordered, capillaries continue to contract, and hair follicles cannot get enough blood supply, which leads to a large number of hair loss. Therefore, we should try to have a good rest in summer. Even if we can't sleep in hot weather, we should stay in bed to maintain our mental state and prevent autonomic nervous disorder caused by physical fatigue and low immunity.

The above suggestions on what ingredients of shampoo can cause hair loss and prevent hair loss, I hope to help you. For the choice of shampoo, avoid the above ingredients and buy shampoo.
