TRICOLOGY - Questions and answers
Some questions to the Rebitalia trichology expert.
How much hair falls out daily?

The hair has three phases: anagen (growth), catagen (stasis), telogen (rest), phase in which the hair papilla comes off and creates a new hair. For the replacement, daily, fall from 60 to 75 hairs that can reach 150 in periods of spring and autumn. Under normal conditions this does not worry, because the hair papilla will generate a new hair.

When should we worry?

When we begin to notice a receding or a major thinning.

What are the reasons for classical alopecia (hair loss)?

Hair can suffer a fall going into the phase of death ahead of time due to various reasons: stress, heredity, diets, medicines, post-partum, iron or vitamin deficiency, little circulation, excess fat, excess peeling, infectious diseases, washing or wrong chemical treatments, excess toxins, etc. The primary cause remains testosterone which reacts differently on the follicles on the cranial vault.

Is it possible to intervene?

Certainly. In some cases excellent results are obtained, in others a little less, in cases of hereditary fall there is a slowdown. Treatments should be carried out well, for a long time and recommended by experts or hairdressers trichologists.

Where do the treatments work?

The treatments valid for cases of early fall, must act on the hair papilla that is located in the skin, together with the anagen bulb, the only living part of the hair, and is responsible for the birth, growth and death of the hair.

How should it be a good treatment for the fall?

Meanwhile, a good treatment is never for the fall, but must act on the new growing bulbs, the old hair is now dead. Valid cosmetic treatment must act in 5 ways:
1) wash the head in a eudermic manner;
2) stimulate the blood supply of the skin for oxygenation and nourishment of the hair papillae;
3) nourish the scalp;
4) restore the normal hydrolipidic coat of the scalp pH 5.5;
5) give a better appearance to the hair, also operating with components that mask aesthetic degradation.

Is the massage really useful?

For a good treatment, I mean, good products and their good application with stimulating, draining, relaxing massage that will greatly develop the effectiveness of the products.

So, rapture or use refreshing or keratin lotions is not needed?

Kidnapping is useless, because we must act below, in the papilla. The lotions for the fall that are only cold, are just a joke, because the cold is astringent, we would keep up, for a few more days, an already dead hair suffocating the new hair growing underneath. Testosterone inhibitory phytosterols such as saw palmetto are needed. We must open, heat, inhibit testosterone not close and cool or give keratin. The hot-cold action helps because it exerts a pumping on the microcirculation. However, there are no miracle preparations.

Are essential oils useful?

Of course, they have a detoxifying, calming, purifying, hormone-regulating, antifungal, disinfectant action. They penetrate the skin and remain in circulation for 72 hours.

Why do we have oily hair?

Excessive sebum secretion is a problem that especially affects men, because androgen hormones are involved in the filling of the sebaceous glands. But there are several cases also among women, because they have a higher number of androgen hormones or hormonal imbalances. Excessive sebum is often of inferior quality, it oxidizes and degrades, becoming rancid and poisonous to the skin and hair with consequences that lead to seborrheic dermatitis and premature hair loss.

Can you get rid of grease from hair?

It is ridiculous to believe that you are fighting greasiness, but it must be re-educated and the aforementioned consequences must be absolutely avoided. We need to use shampoos that can be called anti-grease, but which actually have delicate surfactants (amphoteric) and calming components. Better still would be to use washing oil. The result will be slight as a decrease in greasiness, excellent in avoiding the consequences over time. Anionic and degreasing shampoos have an immediate effect, but will worsen the situation over time. Do not use shampoos - conditioners and creams because they contain fatty substances, therefore very harmful in the event of the aforementioned anomaly.

What about dryness?

The sebaceous glands, as they can produce a lot, can produce even less than necessary, the skin and hair will therefore appear dry. We will have to intervene with shampoos, conditioners, moisturizing lotions, emollients and especially with protective agents that avoid external attacks, but which are largely vegetable, otherwise, depositing on the skin they will create problems.

Why do we have dandruff?

The skin, to renew itself, flakes continuously. In fact, the outermost layer, the corneum, is made up of many flakes of keratin which are continuously renewed and together with the acid hydrolipidic mantle they protect us from external aggressions and bacteria. When for various reasons this renewal is too fast we will notice a large amount of flakes. The real name of dandruff is "pityriasis" which derives from the name of a beating that is present on the skin, in large quantities, in the presence of dandruff. Dandruff is therefore very harmful to the scalp and hair.

Is dandruff always fought in the same way?

NO. Dandruff can be oily (steatoid pityriasis) in case of skin with excessive sebum; large flakes. Mixed (pityriasis) in case of excessive sebum and sweating, this is the most frequent; medium and resistant flakes. Dry (dry desquamation) in case of little sebaceous secretion and excessive sweating; very fine flakes. It is therefore clear that it should be treated differently. Dry skin cleansing oils are excellent for detaching the scales well, without attacking the acid mantle of the skin. We will then use sulfur shampoos for oily dandruff or pyrithione zinc-based shampoos and emollient vegetable substances because these substances dry out the skin, then we will add essential oils and dermo-purifying extracts. The lotions are excellent, used as disinfectants, also recommended for applications between one wash and another.

Why does hair get damaged, break and have split ends?

This anomaly can occur due to chemical, alkaline, aggressive, too frequent and careless treatments. Or in hair that is weak and prone to atmospheric aggressions and aggressive and poor quality shampoos.

How can you intervene?

The problem cannot be solved because the outer part of the hair is a dead keratin fiber. It is necessary to intervene to reinforce the bulb and momentary aesthetics. First of all, it is necessary to intervene on the bulb with treatments that help the growth of healthy hair. The deep packs of the new generation have a longer duration than balms, but not definitive. Emollient shampoos, good conditioners and acid and film-forming restructuring products should always be used. The acid product closes the scales of the hair.

Is washing your hair often harmful?

NO, sometimes (too much grease, dandruff, dust) it is even indispensable, it is harmful to wash them badly and with bad detergents. The skin is also oxygenated from the outside. If we leave too much fat on the skin, it oxidizes and creates skin problems, the follicle closes and the bulb suffers. Dandruff creates redness on the skin and an increase in bacteria. Good surfactants do not attack the scalp and hair.

What are surfactants?

Water alone does not wash. So we use surfactants which are substances that have the property of decreasing the surface tension of a liquid: these agents dissolved in water are arranged on the surface of each molecule forming an envelope which lowers the cohesion force. When they meet dirt, the part of the surfactant similar to grease (which has a positive charge) binds to it, the other part is related to water and remains in it. The dirt breaks down into droplets which form an emulsion which is removed by rinsing. Surfactants are divided into: anionic with the negatively charged hydrophilic end and the uncharged lipophilic end. They are a little aggressive on the scalp and hair, but they are used to some extent for all shampoos because they wash better since the dirt is positive. Cationic, have a positive head and a negative lipophilic part, they are used added as polishers or disinfectants in small percentages, they irritate the eyes. Amphoteric, they are the best for a good

Can hair problems be solved with a shampoo?

NO, the right shampoo can help solve the problem and keep away, over time, hair loss, dandruff and split ends when the cause is limited to previous unsuitable shampoos.

Can shampoos damage your hair?

Of course, bad quality or unsuitable shampoo can create serious problems for the scalp and hair, especially if used frequently; the same a shampoo - conditioner on an oily scalp or an alkaline shampoo. Baby shampoos are often alkaline so they don't sting the eyes, but they will do damage over time.

Are all shampoos the same?

No, there are shampoos on the market formulated with poor quality surfactants and others with balanced surfactants. My advice is to avoid cheap products because they could cause serious damage. However, there are no natural shampoos, but less aggressive and with the addition of some natural ingredients.

If the shampoo is thicker, is it more concentrated?

No, thicker shampoo is often made less fluid with common table salt or other thickeners. The washing raw materials of the shampoo are fluid.

Does the greater foam determine the quality of the shampoo?

No, the foam is only psychologically important. Unfortunately, the advertising was based on the belief that the more foam a shampoo is, the more effective it is.

Does neutral shampoo mean delicate?

No, the adjective neutral refers exclusively to the degree of acidity and has no reference to the quality and washing characteristics. It should be remembered that the hydrolipidic mantle is slightly acidic, therefore the shampoo is recommended to be slightly acidic to avoid useless work of the scalp's buffer factor. The shampoo must be produced with delicate surfactants.
