Which Keratin Shampoo is best | Bio Keratin Shampoo for everyday use

The shampoos which have bio-keratin are so popular in the market. Keratin is a great invention of the cosmetic industry, when it helps damaged hair to restore protein structure, using keratin for a long time your hair will become softer than ever.

That’s why we chose the top 18 bio keratin hydrating shampoo on the market to recommend and help you improve your hair.

How do I choose Keratin Shampoo

Keratin is a type of protein found in the human body in the skin, hair, nails, and other organs. During the process of straightening and using too much heat, the protein structure of hair can be damaged and the hair is no longer nourished as before. Keratin in shampoo is usually obtained from natural sources, such as animal wool, and then processed to suit human needs. It is formulated and manufactured to restore the hair cuticle, giving it more vitality and restoring hair function. 

However, this treatment process takes time and you need to give your hair a few months to recover. Bottles of bio keratin shampoo will help you somewhat in this process. I’ve also collected some of your questions and answered them below.

What’s The Difference Between A Drugstore Bio Keratin Hydrating Shampoo And An Expensive One?

The main ingredient of keratin shampoo is keratin. So the price difference will be based on the quality of the keratin.

First, as you know, the smaller the keratin molecule, the higher the permeability, just like the skin has different layers, the type of moisturizer that penetrates the multilayer will make the skin moister. So is keratin. The larger the molecules, the deeper they can penetrate the structure of the hair and repair more damaged hair.

Second, it’s the formula of keratin shampoos. Only keratin is not enough, shampoo needs amino acids to do its job properly. For example, Cysteine ​​locks in moisture in the hair and connects the hair cells. Meanwhile, Tyrosine ensures that the color particles adhere to your hair and your hair will keep the color longer.

Does Keratin Shampoo Straighten Your Hair?

Rest assured, the answer is no. Many people are quite worried when using a moisturizing shampoo and bio keratin because it can make their hairstyle not as frizzy as before. But this has never been proven. The only way to straighten your hair is to use heat and a hair iron. Keratin shampoo only makes your curly hair softer, it will not make your hair straight.

Bio Keratin Hydrating Shampoo

Usually, those with dry and chemically damaged hair will prefer to use shampoos containing keratin. Other than that, oily hair girls are afraid of this product because it can cause hair loss. However, I suggest that you alternately use an oil-control shampoo and a moisturizing shampoo so that your hair can both provide enough moisture and can keep the bounce without being flat.

Even better, today we bring several keratin shampoos suitable for all hair types such as oily hair, dry hair, damaged hair, thin hair. To find out which one is the best for you, read each review carefully and check out our final picks!

Bio Keratin Hydrating Shampoo: FAQs

Is Bio keratin shampoo good for your hair?

Bio keratin shampoo can make your hair silky smooth, and manageable. This shampoo can help prevent any hair damage with appropriate usage.

Is Bio Keratin Shampoo sulfate-free?

Yes, bio keratin shampoos are mostly sulfate-free, not leaving your hair dry or fading in color. Most formulations of bio keratin shampoo will help your hair feel soft and smooth, leaving nourishment to your hair’s roots, scalp, and tips.

Can You Show Me How To Choose A Suitable Bio Keratin Shampoo?

Sure, thank you for trusting our website. Choosing a keratin shampoo depends on your hair type a lot.
The first step is to see how damaged your hair is. If it’s too damaged, you’ll probably need an extra bottle of conditioner or a bottle of conditioner, and choose a good bottle of hydrating bio keratin shampoo. If your hair is moderately damaged, not too tangled, and dry, then you just need to shampoo and persevere for a long time about a few months.
Next, what is your hair type? Thin or thick hair? Oily or dry hair? There are people with oily scalp hair but dry roots, so you may need to combine an oil-control shampoo, and a bottle of moderately moisturizing shampoo. If your hair is too dry, then you need a shampoo that is specialized for dry hair and contains many other nutrients besides keratin.
Third, trust brands that specialize in hair care. These brands will be great for you to browse the different product lines and make it easy to repurchase once you run out of shampoo.
Fourth, select customer reviews. There are product reviews with seeding purposes, it’s often not useful and the reviewer hasn’t experienced the product. You need to look carefully and choose reviews that have used the product after a few weeks or months, pay close attention to how they review scent, moisture, shampoo bottle capacity, and its price compared to quality. 

Does Bio-keratin Shampoo Restore Hair Completely?

I know that the main function of shampoo is to clean the scalp. But now many shampoo brands say their products can restore, maintain hair color, provide additional nutrients. That’s true, but not the whole thing. I take an example, if you use a cleanser, its biggest function is to clean, and even if the brand says it helps you stop acne or moisturize your skin, it can’t.
The reason is that, like cleansers, shampoos only stay on the scalp for a certain time, nutrients have not yet penetrated the hair, you have rinsed it out, and the additional nutrients have not yet been absorbed into the hair. Water is also an agent that makes nutrients less permeable. That is also the reason why hair conditioners often require you to incubate for several hours, which is enough time for the nutrients to penetrate the hair.
So it can be concluded that shampoo will be an effective support tool, but it can’t make you completely free of damage, maybe it will help you 80% if your hair is not too damaged. Just like choosing a cleanser according to your skin type, oily skin, dry skin, aging skin, choosing the right shampoo for your hair needs is already successful.

Why Does My Hair Become Dried When I Use Keratin?

Let me explain a little about the permeation mechanism of hair. Hair can only absorb a certain amount of keratin. It’s like a sponge, it’s full of water, inflates, and can’t absorb more. Furthermore, damaged hair will be negatively charged, healthy hair will be positively charged, and only negatively charged hair will attract keratin. So if your hair is already strong or healthy again, the keratin may not be absorbed into your hair anymore.

The second thing is that some brands make large-molecule keratin, the formula is limited, so the keratin can’t penetrate deep into the hair, it stays on the surface and sticks to the surface of your hair. It stays there and causes the hair to become dry, stiff, and brittle. That’s why it’s the same keratin but not all shampoos can restore your hair.
