Alcohol lotions
For To panic about the availability of alcohol in cosmetics is not worth it. And especially do not think that it is a necessary cause of dry skin. The fact that alcohols can act in several roles. For example, as stabilizers, emulsifiers or carriers of active substances. However, they can be good moisturizers. For example, today in cosmetics is often used propylene glycol, which is struggling with dry skin. However, a large number even it may cause irritation.
As part lotions alcohol in small quantities will give a good antiseptic, degreasing and drying effects. It evaporates quickly, so after using such drugs on the skin leaves no marks or sticky feeling. By the way, many wet wipes, purify, contain exactly the alcohol. However, the minimum concentration is about 3-8%.
Vs. Not all spirits are the same. Adversely affect the skin of ethyl, methyl, benzyl and isopropyl. In its pure form they are especially aggressive. Can dilate blood vessels, to start the process of premature aging and cause the formation of wrinkles. Therefore, it is advisable not to use the means, which is composed of similar components.
It is especially important to avoid such cosmetics for Allergy sufferers and people with sensitive skin. The fact that these alcohols literally "stripped" the skin, making it very vulnerable. As a result, it becomes more susceptible to the effects of excessive solar radiation and low temperatures, faster inflamed. On the background of the application of funds from the "bad" alcohols not even the aggravation of acne.
Solution
: the use of alcohol-containing lotions justified only when we dried the individual pimples. Therefore, cosmetic products "tipsy" is needed only for oily and problematic skin.
Parabens in creams
For: very long parabens considered ideal components, devoid of any flaws. But not so long ago around them was a ferocious debate. It was rumored that they can cause allergies and even cancer of the breast. I have to say: it's a contrived hype. Actually parabens in cosmetic composition is required.
They are preservatives, so they allow to increase the shelf life of products. "To deliver" cosmetics from them is impossible. You can only choose the funds in which they are contained in a minimal amount.
In addition, parabens provide protection cream broad spectrum of bacteria and fungi. They are especially necessary in cosmetic products containing large amounts of organic components. The fact that the latter are the perfect breeding ground for germs.
Parabens are safe in concentrations up to 25%. And in cosmetics, there are fewer - not more than 0, 3%. Therefore, the use of cosmetics that contain this preservative, can not lead to health problems.
Vs.
: it is believed that parabens, along with surfactants and fragrances are one of the main causes of irritation and allergic reactions in people with sensitive skin. Of course, some truth in this. But it should be noted that adverse reactions in sensitive individuals may cause any component of cosmetic products.
Solution
: If you are afraid of parabens, try to use cosmetics with floral preservatives. For example, vitamins E and C, propolis, as well as extracts of leaves of birch, cherry, pine bark or seaweed. These ingredients retain the valuable properties of cosmetics, allowing you to make the cream more safe for the skin.
Another example is the tea tree oil and eucalyptus. They also serve as natural preservatives and protects the cream from the harmful effects of bacteria.
However, this kind of cosmetics cannot be used more than two or three weeks. Keep it always in the fridge. In addition, vegetable preservatives have not such a broad spectrum of action, as artificial. Therefore, and can be applied not all cosmetic products.
The silicone in shampoos
For: now many hair tools type silicon, on which there are many rumors. However, this component is not only not dangerous, but even harmless. Allergic reactions to it are much less common than any other substance.
In fact, the silicones are essential components of modern means of hair care products. They can be of several types. In shampoos, generally add a water-soluble liquid form of these substances. Indicated they in most cases as Dimethicone. They create persistent dense foam. Easily washed off with water, do not pollute the hair and leave it feeling smooth.
In the heat-resistant tools, use of volatile silicones, such as cyclomethicone. Often they can be found in tools for styling and sprays of instant Shine. Their goal is to protect the damaged paint, perming hair. Such silicones as if served curls invisible hard film, like "cement" them. They significantly reduce the drying time, make hair more voluminous, soft, silky.
Water-insoluble silicone oil is most commonly used in the manufacture of composite products - for example, conditioners or shampoos "2 in 1". Accumulate, they envelop strands with a protective film, smooth, facilitate combing. And even silicone glue split the hair cuticles, making the surface more smooth and thereby give the hair a beautiful Shine.
Vs.: the constant use of funds from silicones may worsen the condition of the hair. The fact that the expressed therapeutic effect silicones do not have - rather, serve to "cosmetic repair". Hair just covered with a silicone layer and reflects light better due to cuts scales.
However, silicones "lock in hair moisture and nutrients. If used frequently, this leads to the fact that the curls are literally "plugged". First, we see that the hair becomes smooth and shiny - they seem to come alive. But over time, we notice that the curls worse fit, lose volume and healthy look to become weak.
Large quantities of silicones can give the effect of weighting hairstyles. And this, in turn, leads to loss of flexibility of the hair, causing it starts to split and break down the entire length.
So they often use tools, which include silicones, undesirable. The problem lies in the fact that wash silicone oil is not so simple. Finally this can only be done using special shampoos.
Solution:
use silicone products can from time to time. Such funds will be indispensable when you need to quickly give your hair well-groomed and healthy looking. But for safe problem solution it is better to address to the doctor, trichologist.
The ammonia in the paint
Fortoday many women are afraid to buy hair dye, which is ammonia. Supposedly it is very harmful to the hair. However, for many years he, along with hydrogen peroxide, was the main component of the ink. Without these two substances would have been simply impossible to achieve a stable result. Not in vain because ammonia paints are considered the most "long-playing".
The mechanism is quite simple. The first step is exposure to hydrogen peroxide. It cleans the hair, remove the natural pigment, leaving only an empty core.
The second step is the maximum deep penetration and fixation of the artificial pigment, which is due to the ammonia. This is why hair dyed ammonium colors, long does not need refreshing color.
Also, ammonia can be used as a conduit for nutrients - such as protein and vitamins that strengthen hair. Harmless ammonia in the paint - no more than 1, 5%.
Vs.
: naturally, to ensure a lasting effect pigment must penetrate deep enough into the hair. Only then he will not be washed out with shampoo. But this exposure to ammonia inevitably damages the hair, and the peroxide dries them.
Solution: If you are afraid of the negative effects of ammonia, it is better to choose the dyes in which it is contained. However, in this case it is not necessary to count on long-lasting colour.
