What is a Keratin Treatment for Hair?

What is a keratin treatment for hair

Haircare is an overall term for hygiene and cosmetology. There are many processes and treatments for hair to maintain it. One of them is keratin treatment. You have read through all the products above and now you may want to know about keratin treatment. Let me clear first that keratin treatment may vary from place to place. But if we talk about a traditional keratin treatment, it involves a cosmetic product applied for the straightening of the hair for several minutes.

Then the hair may get blow-dried or flat-ironed systematically. This treatment would remove frizz from your hair giving it the alignment, color, or shine depending on the product type and brand. Usually, all the keratin products are infused with keratin protein, a basic building block of which your hair is made. With the passage of time and continuous processing and chemical or heat exposure, your hair may lack this protein, becoming porous and weak.

 When an infused keratin product is applied to this damaged hair, the pores of the hair are locked with essential protein leaving the hair looking more thick, shiny, soft, aligned, and healthy. 

Why Do You Need Special Shampoo for Keratin Treated Hair?

keratin treatment for hair side effects

Just like salon color, the deposited products of keratin treatment would also be removed slowly every time you shampoo your hair. So first of all you need to shampoo your hair only when it’s necessary. And yes, the shampoo you use on keratin-treated hair should have some special qualities so you can minimize the loss of deposited product with every wash. It will help your keratin treatment stay boosted and last longer. You can pick a shampoo from the ones that are listed above.

Always try to choose a shampoo with a mild cleansing effect. The second most important thing you want to make sure of is that your shampoo is free of harmful chemicals like sulfate and sodium chloride. These chemicals sacrifice the health of your hair in exchange for a few days of good look. Choose a shampoo that is botanically formulated with natural ingredients and oils. These shampoos will nourish your hair without causing any dullness or damage to your keratin-treated hair. So having these qualities, the above-mentioned shampoos are worth your money and time in the long run.

Benefits of Shampoo with Keratin Treated Hair and How Does It Protect the Hair?

benefits of keratin treatment for hair

The benefits of shampoo for keratin treated hair may include moisturization, strength, and enhancement of the treatment. Now you may say that you can also get these benefits from regular shampoos. Why do we need a special shampoo for keratin treated hair? Well, the main difference between regular shampoo and special shampoo for keratin-treated hair is the source of these benefits like nutrients, hydration, and moisturization. The special shampoo for keratin-treated hair provides these benefits through natural and botanical ingredients whilst on the other hand, regular products use synthetic fillers and artificial chemicals for this purpose which can cause complications in the long run.

These special shampoos also offer you the prevention of hair weakness, breakage, dryness, and dullness of treatment. You get hair protection from heat, UV rays, chemical exposure, and pretty much everyday wear and tear. There are several added vitamins in these shampoos which may not be present in regular hair products. These sulfate-free and sodium chloride-free shampoos help your hair color or keratin treatment last longer. The natural and botanical formulas of these shampoos treat your hair without causing any side effects.

How to Use Keratin Treated Hair Shampoo

There is a different way to use every different product according to the manufacturers of these products. But the general method is the same for each product. Let’s see how you can use keratin-treated hair shampoo

  • Start by saturating your hair with water. (lukewarm water is recommended.)
  • Apply the keratin-treated hair shampoo thoroughly into your hair paying most of the attention to your scalp.
  • Gently massage with circular finger motion until it lathers and then rinse it off.
  • Use a conditioner (keratin-treated hair conditioner is recommended) and apply to the hair avoiding scalp and roots.
  • Allow it to stay on your hair for few minutes and rinse it off with water.
  • You can repeat the conditioner if it is necessary.
  • Towel dry your hair with gentle patting.
  • You can use this procedure as per requirement and your hair strength. (using every other day is recommended).

The Wrong Shampoos for Keratin Treated Hair

First of all, try to avoid any regular product just to save some money or effort. Any shampoo that has harmful chemicals in it like sulfate, sodium chloride, gluten, dyes, drying alcohol, or parabens, is unhealthy for your keratin-treated hair. These harsh chemicals can cause immediate wear off of your keratin treatment.

The second best piece of advice is making sure to use a hair mask or/and hair conditioner after shampooing your keratin-treated hair. It will nourish your hair and help to protect your hair treatment from heat exposure, UV rays, and chemical damage. It will also enhance and boost up the results of the treatment leaving your hair more shiny and healthy.

Shampoo Is Not All That You Need

You need to take special care of your keratin treatment otherwise it will peel off. You should start by choosing the right shampoo for your treated hair considering the above guidelines. But that’s not all that you need. There are some other things and measures to take care of:

  • Correct use of shampoo.
  • Condition hair after shampoo.
  • Applying hair masks and finalizers.
  • Using essential oils/sprays.
 Apart from these steps, there are some uncommon but very useful products for your hair management and health. 
  • Dry shampoo. (Best for cleansing between your hair washes)
  • Keratin spray and oil. (Handy nourishing products)

Do I Need to use Keratin Shampoo?

No! You don’t need to only use keratin shampoo on your keratin-treated hair. But while selecting the shampoo for your hair, you need to be conscious. You should always prefer mild cleansing shampoos and ones with no harmful chemical init. Sulfate-free, sodium chloride-free, dyes-free, alcohol-free, and ones having essential proteins like keratin with natural oils and vitamins are the best shampoos ever.

The keratin shampoos are specially designed for keratin-treated hair to boost the keratin level into the hair cuticles. If you want to go with keratin shampoo, that’s the best option. Because keratin shampoo provides your hair with keratin protein and all the necessary nutrients that your hair is lacking.

But it’s not “go hard or go home!” You still have the choice to select some other shampoos which you think may be more beneficial for your hair.

Dos and Don’ts after Keratin Hair Treatment

dos and donts of keratin hair treatment

Do’s after Keratin Hair Treatment

  • After keratin treatment, you must not wash your hair for 3 whole days.
  • After three days, continue your shower routine as usual and use keratin shampoo instead of a regular one.

Dont’s after Keratin Hair Treatment

  • Don’t dare to use cheap, sulfate-containing, and clarifying shampoos for keratin-treated hair, for they can dissolve keratin treatment.
  • If you wash your hair every day, try to do so every other day. The more you wash your hair, the faster it washes away the treatment.
  • Don’t change shampoos and conditioners every other day, instead, try to stick to just one good quality keratin-infused product.
  • Don’t style your hair for at least 3 days after keratin treatment. It may spoil your hair post-treatment. Just wear your hair straight down for as many days as you can.

FAQS About Best Sulfate Free Shampoo for Keratin Treated Hair

Question: Which shampoo is best for keratin treated hair?

Answer: Any keratin-infused shampoo from the above list is good for it. But I’ve been personally using L’Oreal Paris for many years and I don’t think I’ll be changing it. It was my first keratin shampoo and I was afraid to try it. But this came out as my best decision ever because it seems like a shampoo stopped damaging my hair further.

Question: What ingredients to avoid in shampoo for keratin treated hair?

Answer: Many products use a mild detergent to lather the hair and making the market. These ingredients include SLS (Sodium Laureth Sulfate), Monoethanolamine, Diethanolamine, Triethanolamine, etc. Other harsh chemicals to avoid are gluten, sulfate, sodium chloride, any dyes, and parabens. These chemicals may dissolve keratin from the hair leaving hair lack in protein, porous, and weak.

Question: Is wow shampoo good for keratin treated hair?

Answer: Absolutely yes! Wow shampoo is sulfate-free, paraben-free, salts-free, plus it is infused with keratin protein.

Question: Is loreal sulfate free shampoo good for keratin treated hair?

Answer: Any sulfate-free shampoo is preferred over sulfate-containing shampoo for keratin-treated hair. L’Oreal sulfate-free shampoo, along with its this quality, also have other utmost benefits to the hair like keratin infusion and botanical essentials like sunflower oil, making it one of the best shampoos for keratin treated hair out there. I personally am using L’Oreal products and I’m very adherent to them.

Question: What does sulfate do to keratin treated hair?

Answer: Sulfate is a cleansing agent present in most cheap hair products. It can wash keratin infusion right out of your hair. It strips the hair making keratin treatment dull and so the lifespan of keratin treatment is shortened.

Question: How to stop hair fall after keratin treatment?

Answer: Your hair may become weaker after treatment. There are some important steps to immediately decrease the hair fall after treatment.

  • Always wash your hair with a mild shampoo followed by a deep conditioner.
  • Enrich your diet with more protein and essential vitamins like B5.
  • Massage your scalp with a few pumps of essential oils for few minutes daily.
  • Avoid messing with wet hair. Your hair is at the weakest stage while it is wet. Let it dry before brushing.

Question: How to maintain keratin treated hair?

Answer: Every good outcome needs some effort. Consider these tips to maintain and increase the lifespan of keratin treatment.

  • As mentioned above, wet hair is at the weakest point. Try to keep your hair dry most of the time and don’t wash your hair for at least the first 3 days after treatment.
  • Use hair products that are sulfate, SLS, and sodium chloride-free.
  • Don’t wash your hair every day or at least not as often as you did earlier.
  • Avoid styling for the first couple of days and keep your hair straight down for post keratin treatment.
  • Change your pillowcase with silk or any other less harsh stuff.
  • Don’t let sweat stay for too long onto your scalp. Use a blow dryer to dry it out when needed.

Question: Is keratin treatment chemical free?

Answer: Keratin is the natural protein and basic building block of which your hair is made. But that’s not all about keratin treatment, because there are many other ingredients in the keratin treatment products. There is a common chemical in them called formaldehyde which is argued as a carcinogen (cancer-causing substance). Some cheaper products may contain even the worst chemicals. However, cysteine smoothing treatment is not formaldehyde-based and contains herbal extracts. It is much safer for one’s use.

Question: Why should I use a special keratin shampoo after keratin hair treatment?

Answer: The keratin shampoo would keep up the keratin infusion into your hair cuticles helping keratin treatment last longer and enhanced. You should use special keratin shampoo after keratin hair treatment to maintain the treatment and avoid any possible damage to the hair.

Question: Why are sulfates (normal shampoos) not good for keratin treated hair?

Answer: Normal shampoos or any shampoo made with sulfate are dangerous for your keratin-treated hair. Sulfate is very rude towards keratin treatment as it may dissolve and strip the treatment leaving hair rough, dry, and weak. Even a small amount of sulfate can wash keratin right out of your hair. It shortens the life of keratin treatment thus must be avoided.

Question: Why do keratin shampoos not foam as much as regular shampoos?

Answer: Normal shampoos use harsh chemical agents like sulfate to lather hair and increase their market. Keratin shampoos don’t usually use such harmful chemicals. That’s why they don’t foam as much as low-quality shampoos. But moistening the hair well before shampooing and adding water during lathering may somehow increase the foam.

Question: Are dry shampoos safe to use for keratin treated hair?

Answer: Absolutely yes! You can use dry shampoo for keratin-treated hair between your regular washes. It is safer than standard shampooing because it cleanses hair while keeping it dry. The more you keep your hair dry, the longer the keratin treatment will stay. But the same principle applies here that you should make sure it is free from sulfate and other harsh chemicals.

Question: When to wash the hair after keratin treatment?

Answer: It is already mentioned above that you must avoid washing your hair for the first 3 days. Styling your hair is also prohibited for as many days as you can. Avoid any type of water contact for at least the first three days after treatment. If you can’t live without cleaning your hair, you can use a sulfate-free dry shampoo.

Question: How often should I wash my hair after keratin treatment?

Answer: To be honest, washing your hair daily is an unhealthy activity for your hair. Washing or shampooing your hair every day may lead to the dullness of keratin treatment and loss of natural oils present in the scalp.

Washing during the first three days is strictly prohibited. Then you can make a routine of washing your hair every other day. But some professionals also recommend keeping a gap of up to 3 days. You can use dry shampoos during these gaps. Keep in mind that the fewer you wash your hair, the longer the keratin treatment will stay boosted.

Question: What type of conditioner is good for keratin treated hair?

Answer: Same as the shampoo for keratin-treated hair, I recommend not using a regular conditioner. Instead, go with keratin, amino acids, and collagen-infused conditioners. Also never forget to choose one that is sulfate-free and contains botanical ingredients rather than harsh chemicals.

Question: How to find out if the shampoo contains hidden sulfates?

Answer: Both sulfate and SLS are equally dangerous for your hair. The high foaming/lathering shampoos are argued to contain these types of chemicals. If it produces a lot of foam and lathers hair easily, it may contain SLS or sulfate. Some shampoos might also contain sulfate in other forms such as Diethanolamine, Triethanolamine, Sodium C14-16 olefin sulfonate, and Disodium Laureth sulfosuccinate. You need to avoid these chemicals as well.
