Recover the shine and suppleness of your hair with this keratin oil for hair. It is a nourishing and revitalizing treatment that will restructure your hair fiber.
17,30 £ on AmazonMiracle. This adjective was not chosen at random, because if we believe the many positive feedbacks on this keratin oil for hair, the result is visible as soon as we apply a few drops on the hair. Tone, shine, softness: this is what you gain in the short term while the keratin contained in this formula acts in depth to revitalize the hair, weld the scales, repair breakage and split ends.
The other main argument of this keratin oil for hair lies in its anti-aging action. Indeed, it forms a protective barrier against the various aggressions that accelerate this process, such as UV rays, climatic hazards, the salty atmosphere of the air by the sea, etc. To do this, this miracle oil quickly releases keratin to compensate for what is lost daily. Nevertheless, because it is very nourishing, it should not be applied to the scalp.

First of all, you must evaluate the condition of your hair fiber and scalp, as this will determine your hair keratin needs.
Do you have dry, damaged hair with split ends? This means that your hair fiber is seriously lacking in keratin. You can then allow yourself anything: detangler, serum or oil based on this protein that will allow you to have a healthier hair.
Do you have fine, sensitive hair? Beware, at the slightest drop in keratin levels, your hair will be damaged. So remember to use keratin-based serum or conditioner regularly. If your hair is greasy, avoid oil or take care not to put any on your scalp.
Do you have normal, well-toned, voluptuous hair? Keep it that way by including a keratin-containing hair product in your ritual: a shampoo, mask, serum or cream. There's no need to invest in a full line so you don't overload your hair.
Certainly, there's only one keratin for hair, but hair care experts have managed to mold them to achieve specific results. So, before browsing the various products on the market, ask yourself the question: hair keratin for what?
Do you want to perfect your straightening? Do you want to repair your damaged hair and close the scales? Do you want to make up for the harmful effects of coloring, bleaching or perming? Do you want a product to better discipline your hair or to protect it from the heat of a blow-dry or a straightening/curling iron? Are you looking for a product that will help you keep your hair voluptuous? Keep the answers in mind: it will help you find the right care with keratin for hair.
As in all cosmetic and hair products, you have the choice between organic keratin for hair or industrial keratin. Both schools hold strong arguments: those of the organic rely on its healthy, ecological and environmentally safe aspect, while the industrial version defends itself with research and visible results at first use. It is then up to you to choose according to your personal convictions.
Today, keratin for hair comes in several forms. When it is not the main component of a shampoo or a hair mask, you can have pure keratin in the form of liquid, oil or serum to be applied on dry or wet hair; and this, without rinsing.
Each form is associated with a specific virtue: liquid keratin for hair softens and strengthens hair while making styling easier, the serum version nourishes and keeps scales tightly closed, and keratin oil for hair gives shine, tone and discipline while protecting against heat.
How can we not think about the capacity of the bottle or flask containing keratin for hair? Although basic, this criterion allows us to evaluate the quality-price ratio of the product. It would be a shame to pay several dozen euros for keratin that will be used up in a week! It would be better to invest in a 100 ml container or more to be sure to last at least a month.
We talk about it without really knowing about it, keratin for hair is much more than a name highlighted on a hair care label. It is a protein naturally secreted by the body and makes up 95% of hair. However, the stock of this protein does not renew itself while keratin gradually dissipates due to aggressions such as prolonged exposure to the sun's rays and heating devices (blow-drying, hair iron), coloring, bleaching, etc.
However, hair keratin plays a major role.
When the stock of keratin decreases, it will be necessary to provide some in order to keep the hair healthy and able to grow naturally. Hence the value of keratin hair care products for hair!
Know that you can very well combine keratin for hair with other nourishing, moisturizing and protective elements. Of course, we are talking about natural ingredients with indisputable virtues.
When it takes on the texture of a gel to become a serum, keratin for hair can be mixed with other essential ingredients, such as argan and coconut extract. Usually applied to dry hair, it provides softness and shine to your hair. In addition, keratin serum is suitable for all hair types, even oily ones.
If you blow-dry your hair or give it movement with a curling iron, consider applying a few drops of keratin hair serum beforehand. Indeed, this product has a thermoprotective virtue to preserve the hair fiber against heat. In addition, it will help reduce frizz that spoils the final look.
Keratin for hair, when presented in a liquid form, is used as a detangling, moisturizing and protective lotion for hair, whether it is normal, oily, damaged or weakened. It is a liquid to be sprayed directly onto the hair before styling or blow-drying, as it helps to discipline your hair.
Note that regardless of the nature of your hair fiber, nothing prevents you from using the liquid form of keratin for hair. However, remember not to overuse it to avoid dripping it everywhere. For a better application, spray the lotion on each strand that you can then shape as you wish. Rest assured, even if the liquid keratin wets the hair, it dries very quickly and you will have an excellent result.
Keratin oil for hair seduces by the fact that it is suitable for all hair types, except for those that are oily. This is because the oil always has a greasy and very nourishing aspect. Besides, even if you have dry or normal hair, it is not recommended to put it on the scalp and roots, but only on the hair shaft, especially the ends.
Keratin hair oil is the best solution to compensate for the daily loss of keratin. It is also recommended if you live by the sea, in a very sunny location or in a very cold area. Indeed, keratin oil protects your hair against various aggressions and delays the aging of the hair fiber.
Argan oil and keratin for hair are both among the ingredients that are found most in hair care. If their virtues are not in doubt, which one would be better for the hair?
Argan oil is one of the most sought after natural active ingredients in hair care. This is undoubtedly due to its components: it contains a large number of unsaturated fatty acids that nourish without weighing down the hair, such as omega 6 and oleic acid. In addition, argan also contains natural antioxidants and sterols; elements that help hair become stronger, more flexible and more radiant.
As for hair keratin, you can find argan oil as is as you can have it in shampoos, masks or other hair care products. However, remember to moderate the dose of argan if you already have oily hair, because the very nourishing aspect of this element may accelerate the secretion of sebum.
The lack of keratin for hair is felt as soon as it becomes brittle and dry, or the ends are split. Keratin is a protein that is naturally present in the hair, but whose stock is not renewed. It must be "reinjected" into the hair fiber in order to strengthen the scales and tone the hair.
In addition to its repairing virtues, keratin for hair is also said to have nourishing, moisturizing and, above all, protective properties. Indeed, it forms a protective barrier against the heat contained in the hot air of blow-drying or the high temperature of curling or straightening irons. If you apply keratin to your hair before styling, it will be disciplined, easy to style and frizz-free!
Argan oil and keratin for hair both work for the good of your hair. Without opposing each other, they are two ingredients that complement each other and will do wonders for your hair fiber. Nevertheless, keep in mind that you must dose the argan oil well, especially if you have oily hair.
If keratin makes up 97% of your hair, it can only do it good. But if you're not sure, here are 5 good reasons to buy keratin for hair.
Those who have long hair probably know the difficulty of detangling it, especially after exposure to wind, snow, pool or sea water. If you apply keratin for hair before taking the brush or the comb, you will see that they will be more docile, conciliatory and especially disciplined. You don't have to straighten a rebellious strand with your straightening iron or blow-dryer anymore, because keratin helps it stay in place!
When your hair becomes brittle, when it feels rough to the touch, when the ends become split and seem brittle, this is a sign of a serious keratin deficiency. In this case, you must help your hair to recover its natural composition by using keratin-based hair care products. Thanks to this protein, the scales will knit together to give a smooth and silky appearance while making the hair fiber stronger.
If many hair care specialists rely on keratin for hair, it is because it is a component that moisturizes and nourishes the hair. Indeed, keratin has an outer layer that traps water inside each hair. In addition, it contains some fatty acids and antioxidants that provide a substantial nutritive contribution to your hair.
Keratin is a protein that is naturally present in the hair and is the major component of the hair. So, if you choose keratin hair care, it means that you are helping your hair to grow and develop in its natural condition. Because the keratin supply diminishes over time, you're keeping it replenished!
The outer layer of hair keratin forms a protective barrier against various aggressions such as the sun's UV rays, excessive heat (hot air from blow-drying, high temperature from straightening or curling irons), chlorine or salt contained in swimming pool and sea water, etc.
In our opinion, the best brands of keratins for hair in 2022 are :
Since its creation in 1996, the Byphasse brand has managed to quickly go beyond the borders of Barcelona to become a reference in cosmetic and hair care in Europe. Its range of keratin-based hair care products is highly appreciated by consumers, and its affordability is certainly a factor.
It is a French brand associated with luxury and high-end. Considered a must-have brand in the beauty world, this brand offers keratin hair care lines that seduce consumers.
Capello Point is an Italian brand that has conquered all of Europe with its uniquely effective hair care products. These keratin-based hair care products are unanimously acclaimed, except perhaps for their price!
In GK, there is Global Keratin, a name that says a lot about the dexterity of this brand in the handling of this protein so dear to the hair. It's easy to understand why professionals are so keen on the brand's keratin-based hair care products.
Redist Professional is the women's branch of RedOne, a company that specializes in hair care and cosmetic products. This brand's keratin hair care products seem to be popular with the general public.
The diagram below will help you to get an idea of the typical prices for each price range (entry-level, mid-range and high-end).
However, more expensive does not necessarily mean better.
We therefore advise you to always consult our ranking before deciding, rather than blindly relying on price ranges.
Space out the use of keratin hair care products.
It is not recommended to overload your hair with keratin. It already contains keratin naturally, so it is up to you to provide the missing dose according to the condition of your hair. If your hair is very dry and damaged, you can use it daily, but be sure to leave one day off a week. If your hair is normal and healthy, you should avoid using keratin for hair every day and use it 2-3 times a week.
Mix keratin hair care with other items.
Keratin for hair can be combined with other ingredients, your hair will be better off. This can be argan oil for its antioxidants, coconut oil for its nourishing side, shea oil for its moisturizing benefits, etc. However, remember to only choose elements that are adapted to the nature of your hair fiber: if you go all out with shea butter, for example, it risks greasing your hair.
Apply keratin hair care before heat exposure.
Before blow-drying, straightening your hair with an iron or curling it, consider first applying a keratin-based hair serum or spray. These elements have anti-thermal properties that will protect your hair from high temperatures. This way, you will also avoid frizz.
Carefully maintain your hair after a Brazilian keratin smoothing.
If you go to a beauty salon, you will discover that they use keratin for hair as an essential ingredient for a Brazilian straightening. But the practices associated with this type of straightening are not without risk to the hair; hence the importance of using sulfate-free shampoo, keratin mask and alma or castor hair oil.
Try homemade keratin hair care.
If you run out of keratin for hair, you can improvise a mask with the juice of one lemon, 3 tablespoons of cornstarch and 2 tablespoons of olive oil. The lemon will make your hair shine while the cornstarch will provide a good protein boost while buffering excess oil. And, of course, olive oil is known to be nourishing and moisturizing.
To make keratin for hair yourself, all you need is lemon juice, cornstarch and a little olive oil. You use the mixture as a mask to apply to wet hair and rinse after a few minutes of standing time. In this comparison, we found ready-to-use keratin hair care products.
The answer to this question depends on the type of keratin hair care products you choose. If it's a serum, you can use it daily on any hair type. For the liquid version, use it as a detangling and moisturizing solution. You can also use it before using a hair iron to prevent frizz. Finally, keratin oil for hair is used like any styling cream.
The way to apply keratin for hair depends on the effect you want; besides, this is among the criteria to consider before choosing one. To discipline your hair and prevent frizz, for example, spray a few sprays of serum or liquid keratin directly on the hair. If you have long hair, apply keratin before using a comb to make detangling easier.
Already, you should know that hair naturally contains keratin, but it decreases over time and with aggressions (UV rays, high temperature, etc.). Hence the need to use keratin for hair! On the other hand, if you notice an excess, just wash your head with a neutral shampoo, without keratin and without sulfate.
The answer is immediately no. Keratin even makes up 97% of hair, and when the supply of it dwindles, hair becomes dry, brittle and breakable. However, this does not mean that you can use keratin for hair excessively, you need to space out the use of it. As you know, too much nourishing care can make your hair greasy and heavy.
