Brazilian Keratin Research Hair Treatment – Healthiest Product

keratin treatment

About the Product

If you’re looking for one of the most commonly-reviewed keratin treatment products, check out the Brazilian Keratin Professional Research Treatment.

The treatment is one of the easiest to use, and despite being so user-friendly, it’s actually quite advanced. It works to straighten, smooth, repair, condition, and strengthen hair. If you have frizzy, rough, or hard-to-manage hair, you’re going to love this stuff.

It works to restore a natural shine and smoothness by healing the hair from the inside, out. Many keratin treatment at home kits only address the issues on the outside of the hair strands, but this provides a very temporary, superficial solution to the issue at hand.

After just one application, you’ll find your hair more elastic, shiny, and softer than ever before. It will leave your hair straight and smooth anywhere from a period of four-to-six months, depending on your hair’s condition and many external factors.

What kind of ingredients does it use?

Coconut Oil, Argan Oil, proteins, and various Amino Acid complexes are used to strengthen and nourish the hair.

Our Experience

First of all, there are five different formulations available to match specific hair types. Make sure you choose the one best suited for yours.

Be prepared to set aside at least 2 to 3 hours out of your day, depending on how thick and long your hair is, along with your hair type, condition, and how well the person applying it can perform the application. Oh yes, it’s also essential that you have someone else do it. It’s too difficult to do on your own.

You’ll also require a hot flat iron that can reach 450F or above, blow dryer, comb, clarifying shampoo, and make sure you’re working in an area that’s well-ventilated because the product can irritate the eyes and breathing.

This package also came with some free hair clips, which were very much appreciated and useful!

It’s essential that you do follow directions, or else you can seriously damage your hair, or simply not see the results you were looking for. It is tedious, and you should definitely wait at least 3 hours, but preferably a full day before washing hair aside from the initial wash.

What We Loved

  • Lasts up to 6 months
  • Doesn’t require days of wear without washing
  • Works well with various hair types
  • Smooths, softens, and straightens effectively

What We Didn’t Like

  • Can irritate breathing and/or eyes
  • Very tedious – requires another person to apply it for you

OGX Weightless Healing Anti Breakage – Easiest Product to Use

keratin hair treatment

About the Product

OGX is a company that is personally one of our favorites. With that being said, we knew we weren’t going to be disappointed when we tried their Weightless Healing Anti-Breakage Keratin Treatment.

The product is great for all hair types, which unfortunately isn’t the case for many other keratin treatment products. It works to instantly nourish, strengthen, and straighten the hair, and you’ll see the most noticeable differences with hair that is already dry, brittle, and/or damaged.

The conditioning spray oil can be used after styling, or simply just to tame some flyaways and give hair an added level of smoothness and shininess.

The product itself is packed full of Moroccan Argan Oil, along with vitamin E and antioxidants to keep hair healthy from the inside-out. It’s not just going to keep your hair looking great temporarily – but for a good while as it nourishes the hair.

Our Experience

Let’s be real: most of us have color-treated or heat-damaged hair in some way, shape, or form. It’s not great, but it’s the reality. One thing that really drew us into this keratin treatment product, was the fact that it does work with all hair types. Fine, dry, curly, course, color-treated, whatever: it works.

How do you apply it?

It’s much easier than most at home keratin treatments. All you do is make sure your hair is well-washed and damp. Simply spray it all over before it dries, and you’re all set. If you’re looking to simply calm flyaways, you can lightly spray it on your hair after it’s all dry and styled.

The smell is wonderful, and actually light – a welcome contrast to most keratin treatments we’d encountered. You also only need a tiny bit. Don’t worry about it making your hair greasy, however. The oil itself is very lightweight, and you won’t have to deal with it weighing your hair down.

How long do the results last?

This will greatly depend on the condition of your hair and your hair type, but usually, it’s just going to be a daily thing. You’ll have to reapply it every day, or every time you wash your hair. With coarser, more thick hair, you may have to reapply in the evening.

What We Loved

  • Very easy and quick to use
  • Can be used on all hair types
  • Can be used on damp or dry hair
  • Light, pleasant scent

What We Didn’t Like

  • Only lasts for one day

Keratin Complex Natural – Most Well Known Product

keratin hair straightening

About the Product

One of the few professional keratin treatment products for at home use, is the Keratin Complex Natural Keratin Smoothing Treatment. That may be a mouthful of a title, but it’s actually pretty straightforward.

The signature smoothing solution stands out in a variety of ways. First off, it’s one of the few that are actually OSHA (Occupational Safety and Health Administration) compliant, so you can rest assured it is safe to use. Second, it doesn’t actually change the chemical bonds of the hair like so many others do.

It works to add shine, while increasing the manageability of unruly/frizzy hair by infusing keratin deep into the cuticles of the hair shaft. This is what’s going to give you that ultra-smooth, silky feeling that you’ve been craving.

We’ll be honest – it’s not the most affordable product around, but if you’re looking for a premium product, sometimes you may have to pay a premium price!

Our Experience

This top rated professional keratin treatment isn’t really difficult to use, but it is a bit tedious, as well. You’ll probably want to do this when you have at least a couple days off of work or any important meetings you need to attend. You’ll want to wait 72 hours before washing your hair, so really keep this in mind before you start!

at home keratin treatment

Right away, we noticed that it doesn’t have a pungent smell like the vast majority of keratin treatments do. It wasn’t as irritating to the eyes or lungs, either, which is a huge relief!

Ideally, you’ll want to have a comb to make sure it’s evenly-distributed throughout the length of your hair, as well as a flat iron, and a hair dryer. It’s definitely preferable that you have someone you can do this for you, as it will be difficult to do on your own.

The instructions are pretty standard for most keratin treatments. If you follow them, you will be good to go.

We highly recommend that once the initial 72 hours are up, you use a sulfate-free shampoo and conditioner on your hair. Sulfates can be damaging to the hair and also remove keratin faster.

So, how long do the results last?

The company claimed 6 months or longer, but in our experience, it was more like 3.5 – 5 months. Of course, this will greatly vary, depending on the person!

So, were there any downsides?

Yes!

It contains formaldehyde! While this is pretty common, it was still kind of disappointing to see.

What We Loved

  • Professional-quality
  • Results last for a relatively long amount of time
  • No pungent odor
  • Works well with various hair types

What We Didn’t Like

  • Contains formaldehyde
  • Expensive

Tresemme Keratin Smooth 7 Day – Best Budget Product

hair smoothing

About the Product

We all know Tresemme. Either we’ve used the products before, or we’ve seen them in the drugstore or on a commercial. It’s absolutely a household name, and one of the reasons for that is, they provide affordable, reliable products, consistently.

Their products often compete with professional-level ones that are much more expensive, and the Tresemme 7 Day Keratin Smooth System is a perfect example of that.

Infused with keratin (surprise, surprise), it works to give you salon-quality results at a fraction of the price, and much more convenience. It definitely won’t last as long – on average a week – but if you’re looking for results for a vacation, perhaps, or just want to test out a keratin treatment, then this is your new go-to.

Our Experience

Going into it, we didn’t really know what to expect. We’d already used Tresemme products before, and some were wonderful, and some were just average. However, we were pleasantly surprised with the results seen with keratin treatment product.

How does it work?

best keratin treatment

Well, you will need a flat iron, because it’s what’s going to give you that extra edge for an ultra-sleek, smooth finish. The application process in total, will take minutes. Simply make sure your hair is still damp, divide hair into sections, and dispense a couple of pumps into your hands. Rub together, and apply to each section. Make sure it’s evenly distributed by using a comb, and blow-dry hair completely. By finishing off with a flat iron, you’ll seal it all in.

The scent is very mild, and what we’ve come to expect with Tresemme. Not too strong, not chemically-smelling.

If you’re looking for a high-quality keratin hair treatment at home, but are shopping on a budget, then we couldn’t recommend this one more!

What We Loved

  • Excellent budget product
  • Easy-to-use, great for beginners
  • Doesn’t contain formaldehyde
  • Pleasant, mild scent

What We Didn’t Like

  • Doesn’t last very long

GKhair The Best Keratin Hair Taming System – Editor’s Favorite

hair straightening treatments

About the Product

A product named “The Best Keratin Hair Taming System” is saying quite a lot, no? So, right away, we had high expectations for this bottle. We have to say, we weren’t disappointed!

If you’re looking for a shot of rejuvenation, while straightening and strengthening hair for months, then look no further.

This treatment works to reduce to stiffness in your hair, creating silky-smooth, soft locks that will look and feel much healthier and more natural. Juvexin works to condition and moisturize the hair from start-to-finish, while the keratin improves the hair’s texture, making it stronger against heat and any other potential damage.

It isn’t the most user-friendly product to use, but if we compare it with most other keratin at home treatments, this one is honestly one of the easier ones to get a hang of.

Our Experience

First off, you’ll probably notice the price. It isn’t exactly cheap, but we will say that it was worth it to us. It delivers real results, in a short amount of time, and it lasts for months and months!

You do receive a pretty good amount, so the cost per application is reduced a bit, but still.

Application will be much easier if you enlist the help of someone else, as you’ll want to have your hair and scalp thoroughly cleaned, you’ll need it separated into sections, applied evenly, then have a blow dryer and flat iron taken through each section multiple times.

What kind of results did we see?

Honestly impressive ones. Our hair was smooth, soft, and manageable just after one application. You know how many children’s hair is? Soft and untouched by heat or color? It’s pretty much just like that. If you want to give your hair new life, then we really recommend the GKhair Best Keratin Taming System.

What We Loved

  • Professional quality
  • Gives lasting results for up to 5 months
  • Doesn’t have an overpowering smell
  • Smooths, straightens, and strengthens hair

What We Didn’t Like

  • Expensive

How To Pick The Best Keratin Hair Smoothening Treatment For You

Now that you’ve gone through each of the best keratin hair smoothing treatments, you may be a bit overwhelmed by how many great ones there are. You may be wondering which one is best for you? Are the cheaper ones just as good? Are the expensive ones worth it? Don’t worry! We’ve gone ahead and created a user-friendly buying guide to make sure you’re not missing out on anything, and getting the best bang for your buck!

what is keratin treatment

Price

First of all, you’re probably going to take into consideration how much your new keratin smoothing treatment is going to cost you. It’s important to note that price doesn’t always equal quality. There are plenty of the more affordable options that work just as well as the more expensive ones.

However, first create a budget for yourself, and don’t go over that number. You don’t want to end up with buyer’s remorse – not that we think you will. It’s always better to be safe than sorry. No matter what your budget is, we have something available for you on here.

Duration

How long would you like the smoothing effect to last? Are you looking at the long-term, like for four months or more? Great, then you’ll probably want to go with one of the two professional options on our list. Perhaps you’re going on vacation and don’t want the humidity to obliterate your hair. Wonderful! We have short-term options for you that will last for days, or perhaps just a couple of weeks.

Ease of Use

It’s important when using a keratin treatment at home, how easy it is for you to use, because many should be used with someone else applying it to your hair. If you don’t have anyone willing to or qualified to be doing it, definitely look into an easier option, such as the Tresemme or OGX options we have listed above.

Again, it’s better to be safe, than sorry, especially when it’s concerning powerful chemicals that can seriously damage the hair if used incorrectly. Don’t rush the process. It’s important for it to be done right – not quickly.

Hair Type/State

keratin for hair

Evaluate the current state and type of your hair. Unfortunately, not every product is designed for every hair type. If you have very stubborn, coarse hair, for example, some of the more gentle products may not give you that drastic effect you’re searching for.

If you have straight or fine hair, you may want to start out with one of the more gentle options first, and go up from there. Some keratin smoothing treatments contain some harsh chemicals that may be too intense for delicate hair.

Conclusion
