**Химик про волосы — 96% женщин точно об этом НЕ знают! — Transcript & Summary | SozAI** Source: https://sozai.app/transcript/chemist-hair-facts-women-ignorant/ Expert explains why expensive shampoos don't guarantee healthy hair and how to properly care for scalp and hair shaft. ## Key Takeaways - Expensive shampoo alone cannot improve hair health due to the dual nature of scalp and hair shaft. - Effective cleansing depends on surfactant formulation, not foam quantity or sulfate presence alone. - Shampoo should be applied primarily to the scalp with gentle massage for best results. - Daily washing is fine if it suits your hair type and scalp condition; no evidence supports 'training' sebaceous glands. - Damaged hair cannot be fully repaired cosmetically; trimming split ends is necessary. ## What the video covers - Hair consists of a living scalp and a non-living hair shaft, requiring different care approaches. - Shampoo cleans the scalp without irritation, while conditioner protects the hair shaft from damage. - Lather amount does not indicate shampoo quality; surfactants clean by surrounding grease and dirt. - Sulfates like SLS and SLES differ; sulfate-free shampoos are not always gentler. - Proper shampoo application focuses on the scalp with gentle massage, not just hair length. - Diluting shampoo is unnecessary and can harm product preservatives. - Daily hair washing is acceptable and depends on hair type, scalp condition, and personal comfort. - Cosmetic products can temporarily improve hair appearance but cannot fully repair damage or split ends. - Itching or redness after washing may indicate sensitivity to shampoo or other factors, requiring evaluation. - Hair shedding during washing is normal and not necessarily caused by shampoo. ## Chapters 1. 00:00 Why Expensive Shampoo Won't Save Your Hair 2. 01:13 How Shampoos Work and Lather Misconceptions 3. 02:30 Proper Shampoo Application and When to Wash Hair Length 4. 03:42 Understanding Sulfates and Shampoo Ingredients 5. 06:15 Daily Hair Washing and Sebum Production Myths 6. 07:43 Dealing with Scalp Irritation and Hair Shedding 7. 08:51 Hair Masks, Water Temperature, and Final Hair Care Tips 8. 11:14 Normal Hair Shedding and When to See a Doctor Answers ## Questions about this video Does the amount of foam indicate shampoo quality? No, the amount of foam is not an indicator of shampoo quality. Foam consists of air bubbles stabilized by surfactants, and some effective shampoos foam moderately while others foam abundantly without cleaning better. Should I be afraid of sulfates in shampoos? Not necessarily. Sulfates like SLS and SLES differ in mildness, and the overall shampoo effect depends on concentration, combination of ingredients, pH, and usage. Sulfate-free shampoos are not always gentler. Is it harmful to wash hair every day? Washing hair daily is not harmful if it suits your hair type and scalp condition. There is no scientific evidence that frequent washing causes the scalp to produce more sebum. ## Full Transcript — Download SRT & Markdown 00:00 Speaker A Why won't an expensive shampoo save your hair? You can buy the most expensive shampoo, study its ingredients perfectly, and still end up making your hair worse right while washing it. Because in the shower, you are cleaning two completely different things at the same time. The first is the living scalp. It contains sebaceous glands, nerve endings, immune cells, and hair follicles. The second is the hair shaft, which we see, observe, and touch, and it is not alive. Hair does not breathe, does not feed, and is not truly capable of healing or regenerating itself. It creates a paradox. With shampoo, we must clean the living scalp without irritating it, and with conditioner, protect the dead protein fiber from further destruction. 00:13 Speaker A Now let's figure out how to do that. Why does a large amount of foam say almost nothing about the quality of the shampoo itself? Do we need to fear sulfates? Can you wash your hair every day? And why might a person see a whole bunch, a whole clump of hair in the drain, even though the shampoo didn't cause any hair loss before? 00:29 Speaker A So, what is hair made of? If you look at a hair under a microscope, its surface resembles a roof, a tiled roof. The outer layer is called the cuticle. Beneath it lies the cortex—this is the main mass of the hair, which determines its strength, elasticity, and also its color. The more the cuticle is damaged, the more the hair snags on neighboring hairs, tangles, breaks, and light reflects off it less evenly, so it looks dull. The cuticle is damaged not only by shampoo: it can be affected much more by bleaching, perms, constant straightening, high heat, UV rays, and, by the way, mechanical friction or damage. Remember, in the summer, you were sent to your grandmother's for 3 months as a dark-haired brunette. 00:44 Speaker A Like this video if you were sent away and came back a little bit lighter, maybe even bleached, sun-faded. Did that happen to you? 00:58 Speaker A Anyway, leave a like and a comment to let me know if that happened or not. It is important to understand here that cosmetics cannot turn damaged hair back into new, whole hair. It can fill in gaps, reduce friction, create a protective film, and temporarily make the hair smoother. This is useful, but it is cosmetic repair, not resuscitation. Split ends also cannot be permanently sealed. A product can glue them together for a while, but the damaged area remains damaged. And the only way to completely get rid of split ends is to cut them off. 01:13 Speaker A Now, how do shampoos work? Sebum, sweat, dust, particles, styling products, and dead cells accumulate on the skin and hair. Water does a poor job of removing grease, so surfactants—those very detergents—are added to shampoo. And surfactant molecules have one part that interacts with water and a second that is attracted to grease. And during washing, these molecules surround the dirt, after which the water carries these micelles down the drain. But the amount of lather almost never indicates the quality of cleansing. Lather is air bubbles with walls stabilized by surfactants. Some effective cleansing systems foam moderately, and a product with abundant lather does not necessarily mean it cleans better. 01:27 Speaker A But why is there usually more lather during the second wash? It's not because the shampoo didn't work the first time, it's just that less oil remained on the scalp and hair, which was preventing the formation of that thick, voluminous, stable lather. If your scalp and hair are cleaned after one wash, a second one may well be unnecessary. It may be useful after using a large amount of, for example, dry shampoo, oils, silicone styling products, or if you haven't washed your hair for several days. 01:46 Speaker A Should we be afraid of sulfates? The "Sulfate-Free" label has become almost synonymous with safety. But chemistry works a bit more complexly. SLS and SLES indeed belong to the category of anionic surfactants. However, they are different substances. SLES is generally considered to be milder. And besides, the effect of a shampoo is not determined by a single word like SLS or any one component in the formula. What matters is the concentration of components, their combination, pH, the formula, the contact time with the scalp, and how well the product rinses off afterward. A manufacturer can combine several surfactants to reduce the irritating effect of the entire cleansing system. 01:59 Speaker A And conversely, a sulfate-free shampoo is not automatically guaranteed to be gentle. Some substitutes are also capable of irritating sensitive skin. Therefore, the best test for a shampoo is not a trendy label on the bottle, but the result of regular use by you and your scalp. After washing, the skin should not burn, itch, or develop any red patches, and the hair should not turn into a tangled, stiff clump. And feeling a greasy, heavy residue is not the goal. 02:12 Speaker A Where should you apply shampoo? Such an unusual question. Yes. In most cases, shampoo is primarily needed by the scalp. First, the hair must be completely wetted; not just held under water for a few seconds, but the water must truly penetrate between the hairs. Then a small amount of shampoo is distributed over the scalp using the pads of your fingers without any scratching or excessive pressure. 02:30 Speaker A Gently massage in different directions along the hairline, the crown, temples, and the back of the head. The rinsing lather usually cleans the length sufficiently, but this is not an absolute law. If oils or dense styling products with a lot of film-forming agents were applied to the length, or if hair has been in contact with chlorinated water from a pool, for example, the length may also require thorough cleansing. 02:42 Speaker A And do you need to dilute shampoo with water? Absolutely not. Shampoo is already designed to be applied to wet hair. Diluting in your palm sometimes helps spread a thicker product, but it doesn't turn a harsh shampoo into a gentle one, nor does it guarantee a change in its pH. Moreover, you should never pour water into the bottle in advance and leave it there. This can disrupt the preservatives and create conditions for the growth of pathogenic microorganisms. 02:57 Speaker A Can you wash your hair every day? I state responsibly: "Yes, I do it myself every single day." But there is a popular idea. If you wash your hair often, every day, the scalp gets used to it and starts producing more sebum. The fact is, there is no convincing evidence for such "training" of the sebaceous glands. The amount of sebum depends primarily on hormones, genetics, age, and individual skin condition. If a person has thin, straight hair and active sebaceous glands, they may indeed need such daily or regular hair washing. For instance, I do, because sebum spreads easily along straight, thin hair, which is why greasiness quickly becomes so obvious and noticeable. If the hair is curly or dry and the sebum spreads slowly along the length, then such hair might not need daily washing. The right frequency is whatever is comfortable for your scalp, and cleaning that doesn't make the lengths overly dry or tangled. 03:14 Speaker A But as a shampoo manufacturer, I want everyone to wash their hair every day and use up these wonderful shampoos daily. Just kidding. Use them as intended. And what is their purpose? To make your hair beautiful. In the description of this video, you will find links to marketplaces for my wonderful shampoos, conditioners, masks, and hair sprays, which will help me continue to create content for this channel, and help your hair be as beautiful and luxurious as mine—I wanted to say, but that's not the limit of beauty. Oh, such modesty. 03:28 Speaker A Look, enduring itching and walking around for a week with a greasy scalp for the sake of some mythical retraining of the sebaceous glands is absolutely useless. But if your scalp turns red or itches after washing, you should evaluate not just the cleanliness, but also the shampoo itself, the water temperature, the duration of the wash, and the presence of skin conditions, and what a conditioner actually does.

Oh, such modesty. Look, enduring itching and walking around for a week with a greasy scalp for the sake of some mythical retraining of the sebaceous glands is absolutely useless. But if your scalp 07:43 Speaker A turns red or itches after washing, you should evaluate not just the cleanliness, but also the shampoo itself, the water temperature, the duration of the wash, and the presence of skin conditions, and what a conditioner actually does. Damaged hair 07:55 Speaker A usually has a pronounced negative charge. Many conditioning components carry a positive charge and are attracted to such areas. They reduce static electricity and friction between the hairs. Other components, such as fatty alcohols, silicones, and polymers , create a thin surface film that makes 08:14 Speaker A combing easier after washing. Therefore , a conditioner does not feed the hair, nor does it slam the cuticle shut like a window. It makes the surface more slippery and, as it were, reduces mechanical damage. Usually, conditioner is applied to the lengths and, above 08:29 Speaker A all, to the oldest parts of the hair, so to speak, because the older it is, the more damaged it becomes. If you apply a thick conditioner to the roots of thin hair, your hairstyle might lose volume. But the claim that any 08:40 Speaker A conditioner necessarily clogs the skin is also incorrect. Basically, the most important thing is to use the product as intended and rinse it off thoroughly if the instructions say it needs to be rinsed. Do you need a hair mask? As a 08:51 Speaker A manufacturer of hair masks, I maintain that it is absolutely necessary for every application. Of course, as a chemist, I will explain everything to you now—not always, unfortunately, but you use it, I use it, and you use it. A mask is, in essence, a more 09:03 Speaker A concentrated conditioning system. It is convenient to view it as part of your daily or regular routine, rather than as a one-time spa treatment for a special occasion. It is especially beneficial for long, bleached, colored, or frequently heat-styled hair. But 09:18 Speaker A applying it every single time you wash your hair isn't mandatory; or rather, not everyone needs to. There is no universal rule that you must use a separate conditioner after any mask. It depends on the specific formula and the 09:31 Speaker A manufacturer's instructions. You should judge by the results. Has the hair become easier to comb and less tangled, or conversely, has it lost volume and look coated in a thick film? A separate word on water temperature, because that is also an eternal myth. Pores do not 09:46 Speaker A open with hot water and do not close with cold water. That is a nice metaphor, not physiology. Very hot water can indeed dry out the skin more, irritate it, and wash away more lipids from the surface. Therefore, comfortable warm water is usually the 10:01 Speaker A best choice. There is no strict magic number, like 37 or 40 degrees, that exists. The guideline is simple: your skin shouldn't hurt, there shouldn't be any noticeable redness, and a final icy or cool rinse doesn't necessarily make hair shiny on its own. Cold does not 10:20 Speaker A seal the cuticle permanently. If you find it pleasant, rinse with cool water , but you definitely don't need to force yourself to take these ice-cold showers for the sake of your hair. Now let's break down a myth that lives in 10:32 Speaker A many people's heads. If hair squeaks after washing, it means it is perfectly clean. In reality, such a squeak is most often associated with the fact that the cuticle is wide open, the scales are raised and rubbing against each other, rather than the hair being 10:47 Speaker A sterilely clean. This can happen if the shampoo formula is too alkaline for the hair or generally too aggressive. After such a wash, hair is more prone to tangling and breaks more easily. So the squeak is not a cause for pride, but 11:00 Speaker A rather a reason to take a closer look at your shampoo. In general, the best test for a shampoo is not the label or the squeak after rinsing, but what happens to your scalp and hair with regular use. And the most alarming 11:14 Speaker A moment, for which many even watch such videos to the end: you wash your hair and see a whole clump of your hair in the drain. The first thought: the shampoo caused hair loss. In reality, hairs that have completed their growth 11:26 Speaker A cycle and are ready to fall out often stay among the other hairs for some time. And during washing or combing, they are simply released all at once. 11:36 Speaker A If you wash your hair rarely, more hair will come out in a single wash. Simply because they had time to accumulate over several days. So, how do you distinguish normal shedding from breakage? A shed hair is usually long, 11:47 Speaker A roughly the length of your overall hair . Sometimes there is a small light-colored bulb at the end. This is not the entire follicle. You didn't rip it out of your skin, so don't worry. It is just a part of it. Breakage looks 11:59 Speaker A different. Many fragments of different lengths, short broken pieces, and white dots on the tips. Both shampoo and rough handling can indeed affect breakage. But if you notice that your part is really widening, bald spots are appearing, there are painful crusts or 12:14 Speaker A inflammation, or shedding has suddenly increased and won't stop, that is a reason to see a doctor rather than changing your fifth shampoo in a row. 12:23 Speaker A Masks and shampoos do not replace a diagnosis of your follicle condition. Washing your hair properly is not some separate sacred ritual for everyone. 12:30 Speaker A You don't need to fear every sulfate and you don't need to dilute every shampoo. You don't need to endure freezing cold water if it’s uncomfortable for you. It is enough to remember one simple thing. The scalp is alive, its task is to remain clean and 12:44 Speaker A calm, while the hair shaft is dead, and its task is to endure as little friction and heat as possible. As soon as you stop demanding that a single bottle cure your scalp, stop shedding, and resurrect your already dead hair 13:00 Speaker A and split ends, hair care suddenly becomes very understandable. y Topics: hair care shampoo scalp health hair shaft sulfates hair washing hair damage hair conditioner hair science hair loss Study this video - [Flashcards from this video](https://sozai.app/tools/ai-flashcard-generator/?from=transcript&id=81163) - [Quiz on this video](https://sozai.app/tools/quiz-generator/?from=transcript&id=81163) Free, made by AI from this transcript.
