Mythbusters: Should You Use 2-in-1 Shampoo?

On the surface, 2-in-1 shampoo and conditioner seems to make logical sense: Why buy both shampoo and conditioner separately? When you can condense them into one easy step. This allows you to save both time and money in the process.

In this article, we’ll answer the question: should you use 2-in-1 shampoo?

What’s 2-in-1 shampoo?

Most women and men can agree that we feel better when our hair is clean, yet this requires a lot of work and time. When 2-in-1 shampoos hit drugstore shelves, it was truly life-changing. We were getting the best of both worlds (cleansing and conditioning), taking up less space in the shower and saving a couple of extra dollars.
In theory, 2-in-1 shampoo and conditioner is the best invention ever. Cutting an entire step out of your morning? Sounds like a dream.

“The 2-in-1 shampoo and conditioner products became very popular in the ’80s (thanks to Pantene) because consumers were using shampoo regularly but not conditioning enough,” said cosmetic chemist Ron Robinson of “So brands began to incorporate conditioning ingredients into the shampoo, hence the name ‘2-in-1.'”

Previously, it was believed that it was impossible to have a shampoo and conditioner all in one product. This is according to Ni’Kita Wilson, chief executive officer of Catalyst Cosmetic Development. “If you have the cleansing agents in there and they’re effective, then you really can’t leave anything behind to condition the hair. So when they first came out, chemists were the ones skeptical about it.”

The truth about 2-in-1 shampoo

But Wilson believes that Pantene’s parent company, Procter & Gamble, made a breakthrough in the shampoo category. They were able to prove that there was something left behind on the hair that conditioned it. Plus, it reduced the friction between hair strands. “They used an ingredient called Polyquaternium-10. That was one of the first ingredients used for 2-in-1 shampoo and it’s still the main ingredient used today,” said Wilson.

But does 2-in-1 shampoo/conditioner actually work? Sadly, like seemingly all things that could potentially help us get out of the house faster in the a.m., it’s too good to be true, a hair expert tells me.

Shampoo and conditioner, in general, serve two different and specific purposes. Shampoo works to clean dirt and grime out of your scalp, while conditioner helps smooth your strands and preserve their shine. Because of this, grouping them together into one product won’t give you the same kind of results.

“2-in-1 shampoos/conditioners do not really give the hair much conditioner,” says Temur from Sharon Dorram Color at Sally Hershberger. “This is why the process has always remained ‘shampoo then condition.’ When they are done at the same time, it strips away the shine and healthy look that you get when done separately.”

2-in-1 shampoo

Temur himself is not a fan of the double-whammy product. He finds that clients who don’t condition well have a harder time getting a brush through their hair.

It all comes down to your cuticles, which are the “scale-like” outermost layers of your hair that manage the hair’s water content. They are your hair’s first line of defense and contribute the shine to healthy hair.

Shampoo’s purpose is to clean by opening the cuticles to release any dirt trapped in the hair.

This also releases the natural hair oils, leaving the hair quite dry. A conditioner’s purpose, then, is to remoisturize the hair and close those opened-up cuticles, giving hair a shiny and healthy look.

The problem with 2-in-1 is that “a single product cannot open and close the cuticle at the same time,” Davies said.

The hair gets cleaned, but the “conditioner” part of the product only coats the hair with silicone, which doesn’t “close” the hair’s cuticles.

The result is an extremely frizzy head of hair that is hard to manage. It will need to be washed more often.

She added, “There’s only so much you can do in a 2-in-1 shampoo because most of the conditioners are cationic, meaning they have a positive charge, but most of the surfactants [detergents] in shampoos are anionic, meaning they have a negative charge. So they don’t like each other! The biggest problem is in the laboratory in getting the product to be stable by maximizing the conditioning. Once it hits the shelf, the consumer’s only issue is finding out if it provides enough conditioning. Or can they get away without using a daily conditioner.”

The Bottom Line

2-in-1 shampoos can get both jobs done. But don’t get blindsided by an alluring fragrance or rich lather and ignore the health of your hair. “To say that a 2-in-1 shampoo replaces your need for two products, unless you have healthy hair and deep condition on a regular basis, that’s not the case,” said Wilson. “If you are in a rut and are traveling, then a 2-in-1 shampoo may get you through. But you still need a daily conditioner to get optimal conditioning.”


Mythbusters: Curly Hair Is High Maintenance?

Hair, just like our skin, needs its TLC too. Just like how different skin types need certain products and ingredients, we also need to cater to the specific needs of our hair. And just like skincare routines, haircare routines can be equally expensive and confusing.

If you are a curly head, you understand the struggle of making sure your curls are defined. But sometimes, this can seem off as ‘high-maintenance’, because you might need so much more than a straight-haired person does.

But is it fair to deem it that way? In today’s Mythbusters article, we’ll find out if it’s true that curly hair is high maintenance!

Curly hair is high maintenance?

Even people who are knowledgeable about curly hair maintenance still struggle with keeping their curls defined.

First of all, there are so many things you need to note about your curly hair, right from the start.

Not only do you need to have a full-on routine which includes product application and air drying, but you also need to adjust your routine from time to time!

In addition to this, before you can even begin purchasing products for your hair care routine, you need to understand your hair first. You probably don’t know yet what curl pattern you have. Are you a 2A or a 3C? You probably don’t have a clue on what your hair needs or what it lacks. Does it lack moisture? Does it lack protein? Who knows?

It can be overwhelming to start, but luckily there’s a routine specifically made with curly heads in mind.

Understanding your hair

Lorraine Massey’s book “Curly Girl: The Handbook” presents a routine that was specifically made for curly girls.

The routine removes damaging activities and products like heat styling and even shampoo (yes, shampoo!). The routine emphasizes the importance of moisture for the hair since frizz is the number one thing that most curlies experience.

However, if you find yourself uncomfortable with the idea of not using shampoo, feel free to modify the routine to suit your hair. Just remember to add those deep conditioners!

The routine also puts importance on what ingredients you need to avoid and which ones to look out for. Listed down below are some of the most important ingredients to keep in mind. Bring out your notepads and take this down, curlies!

Things to avoid

Things to Avoid

  1. Sulfates – Most shampoos in the market use sulfates because they are harsh detergents used to clean the hair. They clean our hair so well that they also end up removing some of our natural oils and moisture. Examples: Sodium lauryl sulfate, sodium laureth sulfate, ammonium laureth sulfate
  2. Silicones – Most conditioners in the market include silicones. Silicones create a film in our hair strands which make them slippery and shiny. However, moisture cannot penetrate through this film unless removed by a harsh detergent first. Examples: Dimethicone, Amodimethicone, Phenyl trimethicone
  3. Combs and brushes
  4. Alcohols
  5. Fragrance
  6. Head styling

Things to include

  1. Deep conditioners
  2. Humectants
  3. Moisturizers
  4. Protein
  5. Emollients

Some things to keep in mind

Like what was mentioned earlier, you have to be aware of your hair type and what your hair needs before diving into a full-on curly girl method routine.

Even if you follow all the steps, avoid the bad ingredients, and purchase all of the products mentioned in the Top 10 Best Products for Curly Hair, your curls will not be defined right away. It will take some time before your curl definition starts showing and even then, it will not be the same perfect curls every single day.

Some hair types are drier and more dehydrated than other hair types, therefore, needing a heavy and rich product to provide their hair that moisture. However, these heavy products won’t do well for those with light and wavy curls. It might add moisture but due to the heaviness of the production vehicle, it might weigh down their hair.

Understanding what your hair is and what it needs should be the first thing before getting into this routine.

The truth is, keeping your curl definition comes at a price – literally.

Those who are on a measly budget struggle with their basic needs. Some buy sachets and small packets of shampoo just to save their money for other things. But if you’re curly-haired, expect to splurge more on your hair essentials.

When it comes to skincare, it’s really disappointing when something you saved up for ends up not being suitable for your skin type. The same thing can happen to hair. Products for curly hair are already expensive, sometimes twice as traditional products. It can be such a waste to purchase a full range of curly-haired products that are not suitable for your hair type.

But, is curly hair really high-maintenance?

Sure, some may view it as excessive or extra. Others may appreciate it without understanding it. But one thing’s for sure: your curly hair is a big part of who you are and you are more than willing to spend half of your monthly salary just to improve your curls.

Being high maintenance is subjective and some people may look at it as a waste of money and effort. But if it makes you happy and improves your self-esteem, then who cares what anybody thinks? Go rock that curly hair, girl!

Mythbusters: Are Essential Oils Good For Hair?

If you’ve ever spent a good amount of time online and especially on social media, you’ve probably already heard of essential oils before. Essential oils are usually touted as a cure-all for a whole slew of issues, from sleeping problems to allergies.

While the effectivity of essential oils for non-therapeutic purposes is still up for debate, they’ve actually been used as an important ingredient in many hair products for many years now.

In today’s ZALA Mythbusters, we’ll discuss the answer to the question: are essential oils good for hair?

ZALA Essential Oils

What are essential oils?

Essential oils are extracted from plants in order to gain a highly concentrated version of the said plant. They’re usually associated with fragrances since many people use them with a humidifier. However, many companies claim that essential oils can do more than just make the environment smell good.

Simply put, essential oils are also said to be very beneficial for one’s health, depending on the specific oil. When it comes to hair, especially, some oils are said to offer benefits that no other product can in a way that’s both easy and affordable.

The Myth

Using essential oils on hair is certainly not a new or unique concept. Healers from as early as 1000 AD have been known to use presses or steam in order to get fragrant plant extracts – the early version of the essential oils that we see and use today.

Here are some of the benefits that essential oils are said to have and the specific EO that apparently causes them:

  • Smoothens and softens hair – coconut oil, geranium oil, lavender oil.
  • Promotes healthy hair growth – cedarwood oil, clary sage oil, rosemary oil.
  • Stimulates the scalp – Almond oil, chamomile oil jojoba oil.
  • Increases hair shine – Chamomile oil, lavender oil.
  • Greatly moisturizes the scalp – Jojoba oil, rosemary oil.

The Truth

Essential oils are in no way a new discovery. Even way back in 1000 AD, healers have already been using steam or presses in order to collect fragrant plant extracts.

These days, essential oils usually undergo a process called distillation. The final product is very concentrated, which is why you should always use your EO wisely.

That said, EOs are actually completely harmless to any person with no underlying health issue. You could try them all you want and you won’t see any negative effects.

The only reason why you should probably not use EOs too much is due to environmental sustainability. It takes roughly 250 flowers to get 1 ml of EO, so imagine how many flowers had to be sacrificed just to prepare this small but very special ingredient.

DIY Essential Oil Treatments for Hair

If you’ve got essential oils lying around, you might want to try using them as a DIY treatment for your hair.

You can mix them with your regular hair masks or even your shampoos to improve the effects on your hair.

Some of the best essential oils for hair are jojoba oil, clary sage, cedarwood, and lavender.

You can also leave these essential oils on your strands for 30 minutes or even overnight. Wash them in the morning and you’ll notice an improvement in your hair texture.

So, are essential oils good for hair?

Essential oils can be an affordable and easy way to improve your hair’s condition in just a few drops. Depending on the specific oil you use, your hair could improve in shine, strength, and growth.

That said, do know that there is such a thing as using them the wrong way. According to WebMD, overusing EOs or not diluting them enough can cause harmful effects like skin rashes, burns, swelling, and even sores. Some people have also experienced allergies after using certain essential oils. Make sure that you do a small patch test first before using the oil on your entire hair.

Mythbusters: Can Wearing Hats Cause Hair Loss?

If you’ve ever worn a hat in front of a relative before, especially if it’s an older relative, you’ve probably already heard a variation of this statement: “Stop wearing a hat so much, you’ll go bald.”

But here’s the thing. Although we’ve heard that time and time again, we have to wonder, how accurate is it, really? Is hair loss from hats real? Is there a hidden danger to this innocuous activity? How can doing something that’s seemingly so harmless, such as wearing a hat, cause you to go bald?

In today’s ZALA Mythbusters, we’ll answer the question: Can wearing hats cause hair loss?

zala mythbusters wearing hats cause hair loss

The myth: wearing hats can cause hair loss

One very common hair loss myth is that wearing hats can cause hair loss, especially in men.

The myth is often attributed to the fact that men are known to suffer from baldness in their later years, usually referred to as “male pattern baldness”.

Some women also believe that wearing hats can make their hair grow thinner. According to the myth, this is because hats can suppress the strands, therefore flattening it and making it look worse as it grows out.

Lastly, there are some people who believe that wearing hats can restrict oxygen to the scalp, which causes harm to hair follicles. This, in turn, allegedly leads to hair loss in the future.

The truth

So, will hats cause hair loss? Well, hair loss is usually caused by a variety of factors, including age, genetics, lifestyle, medication, medical changes, and hormonal changes.

For women specifically, there are a couple more things that can cause hair loss over time.

Overtstyling hair and using hairstyles such as tight ponytails and braids can trigger a form of alopecia, called traction alopecia, caused by the continuous pulling on the roots.

Doing too many harsh treatments such as perms and hot oil frequently can also cause hair loss due to follicle damage. If a follicle gets damaged, it develops a scar. That scar prevents new hair from growing back.

Can wearing hats cause traction alopecia?

Traction alopecia refers to the type of alopecia that usually develops when your hair is continuously pulled over time. It is not hair loss from wearing hats!

While wearing tight hats isn’t good for your well-being, they rarely, if ever, create enough tension to pull your hair tight. You’re more at risk for traction alopecia if you wear cornrows than if you wear hats.

Can wearing hats cause friction alopecia?

Do hats affect hair growth or trigger friction alopecia? There is another form of alopecia that is usually linked to wearing hats, and that is called friction alopecia.

Friction alopecia refers to the kind of alopecia that develops due to hat stress. This typically happens if you’re wearing a hat that is much too tight for you. The hair follicles get damaged, resulting in bald patches.

However, unlike traction alopecia, this type of alopecia is temporary. Once you stop putting too much stress on your head, your hair will grow back. Of course, if you don’t stop it, your hair may never grow back, but chances of this are quite slim.

Conclusion: can wearing hats cause hair loss?

Luckily for you, it appears that this is actually just a myth, at least most of it. While wearing hats too often can result in some temporary physical changes to your hair, there are no scientific studies that prove that it can cause hair loss in the long run.

That said, you shouldn’t completely rule out the idea that hats cause baldness. Although hats won’t cause you to lose your hair in 20 years’ time, wearing hats that are too tight can in fact be a contributing factor. You might want to stick to loose-fitting hats that will actually let your scalp breathe. Besides, they feel better on your head anyway, don’t they?
