A while back, I bought the wrong shampoo for my keratin treated hair.

It wasn’t until my second wash that I noticed these:

  • Keratin was peeling off: More than what my stylist told me
  • Dryness: My scalp became dry
  • Itchy scalp: Not to mention the embarrassing dandruff
  • Uneven hair: Flat & straight in parts, and frizzy in other parts
  • Styling nightmare: Couldn’t get my hair right
  • Dirty: It didn’t feel as clean as before the treatment
  • Hair breakage: It happens, I was told, but my shampoo wasn’t helping
  • $300 wasted: Yes, I had to do it all over again

Lesson: Don’t ignore the labels, seriously.

And it won’t look good. Trust me.

Okay, like you already know:

You should be using sulfate-free shampoos for upkeep.

But guess what?

Not all sulfate-free shampoos are sulfate-free.

I learned this the hard way.

Let me explain:

Sodium Lauryl Sulfate (SLS) is often disguised as:

You see them in most shampoos.

Other equally dangerous cousins to SLS are:

  • Sodium Laureth Sulfate
  • Disodium Laureth Sulfosucinate
  • Sodium C14-16 Olefin Sulfonate

They are synthetic Lauric acids made from Sulfurs.

Be Warned:

Some products that claim to be “SLS-Free” may contain them in disguise.

Your First 3 Days – Dry Shampoos To The Rescue

Dry shampoo after keratin treatments

Not being able to lather up your head for 3 days will make you feel gross.

I know that feeling.

You are not allowed even a single drop of water on your hair.

Luckily, there’s this sweet magic in a can : the dry shampoo

Deanna Rizziello from confirms this in a Youtube video to her twitter followers:

So What Is A Dry Shampoo ?

It’s a spray powder or liquid that you apply to the roots of your hair.

It soaks up all the dirt and oils.

If you haven’t tried one before, here are some tips:

  • Start At The Roots: Spray lightly at the roots
  • Lift Your Hair & Spray: Lift your hair in sections and spray
  • Let It Sit: Let it sit for a bit
  • Blend It: Use fingers to shake your hair at the roots
  • Flip Your Head Upside down: Fluffen things up
  • Powder Not Liquid: Only use the powder form. Not Liquid

Yes, you can survive these long 3 days with a dry shampoo.

Refresh your hair and knock out that nasty oiliness until your next proper shampoo.

Your Hair Care Is About To Change For Good

The strict shampoo regime after my keratin treatment taught me one thing.

Go organic.

As a rule of thumb, if a shampoo contains a super long list of ingredients, I won’t buy it.

I love the feeling of natural and organic shampoos.

Chemical Free Shampoos

A chemical free shampoo will guarantee you 2 things:

  • No Sulfates
  • No Salts

The 2 main culprits that dissolve keratin coating from your hair.

Why you need a chemical-free shampoo:

  • No Allergies: Natural ingredients are safer (There are exceptions)
  • Mild & Gentle: Tell me how your scalp feels after one wash
  • No Residues: Natural shampoos don’t leave gunk on your scalp
  • More Essential Oils: Eucalyptus oil, Lavender oil etc
  • No Synthetics: You don’t need silicone and plastics in your hair
  • No Artificial Fragrances: Fragrance contains 3100 chemicals
  • Eco-Friendly: Bio-degradable materials

You don’t need to clear out your bathroom cabinet just yet.

But, if you’re thinking of trying an organic shampoo in the future …

Bookmark my tips for reference:

  • Ingredients: Make sure it’s free from colorants and fragrances
  • USDA Organic Seal: Look out for this label
  • First Ingredient: The first ingredient has the highest concentration.

My top picks for chemical free shampoos are:

This is probably what your hairdresser whispered in your ear after your treatment:

Sulfate-Free Shampoo.


Equally as good as organic, but only if you get it right.

Be prepared to navigate through that long list of tongue-twisting ingredients.


You will find sulfates in shampoos that claim to be sulfate-free.

Best Sulfate Free Shampoo For Keratin Treated Hair


Let me explain what a sulfate shampoo does to your hair …

  • It scrubs out natural oil from your scalp
  • It dissolves keratin coating on your hair
  • It strips your hair color
  • And it leaves your hair and scalp severely dry
Watch this Youtube video from hairclub expert.

You Don’t Need Your Chemistry Book To Buy A Shampoo

I totally get it.

When you scan the ingredients, half of the stuff on there don’t make sense.

Even the most knowledgeable of consumers have to decipher labels.

But don’t worry.

I’ve done some research for you and made it simple to understand.

Good Sulfates Vs Bad Sulfates

A little exercise for you:

  • Find your shampoo and check the ingredients against this list below
  • The more GREENS you match the better
  • If the ingredients list matches more than 2 REDS, AVOID it
Find your best sulfate free shampoo after keratin treatment
Find your best sulfate free shampoo after keratin treatment. Pick more GREENS.

Ingredients are listed by their concentration levels – High to low.

So the ingredient that makes the most of the shampoo is always at the top. Some clever manufacturers write their herbal and plant extracts at the top of the list as a decoy.

Be warned, and scan through the full list. Sulfates are not always be at the top of the list. And not the last.

They hide in the middle.

Not all sulfates are bad for your hair.

For example:

  • Sodium Lauryl Sulfoacetate is derived from coconut and palm oils
  • Sodium Laureth Sulfate is a mixture of sulphuric acids & salts

So why don’t they name it as coconut and palm oil?

It’s simple:

The FDA wants to protect you, the consumer from health hazards and deceptive practices.

Also don’t forget: Salt-free (Shampoo without Sodium Chloride).

Salt based shampoos also wash out keratin treatments.

But one thing you need to know …

Regardless of sulfates or not, keratin will wear out with frequent washes (even if you wash with pure water).

Now, I understand some of the shampoos I recommended above may not work for all of you.

For example, you may have allergic reactions to regular shampoos.

But don’t panic.

I have put together a list of shampoos for those with sensitive skin below:

Check them out.

Hypoallergenic Shampoos

28% of us have allergic reactions to hair care products, according to

If you do get rashes, pimples and dry scalp, get a keratin care shampoo that’s hypoallergenic.

Here’s what I recommend:

Use A Keratin Spray For Lighthold Styling

Enhance your hair styles with keratin-infused hairsprays.

Only use a keratin spray for hair after the first week. Don’t rush into it too early.

Wash In Reverse – Conditioners For Keratin Treated Hair

The truth is, you’ll be washing your hair less after your blowout.

What I do is: wash my hair in reverse.

This trick always works for me.

I apply the conditioner with keratin to my damp hair first. Let it sit for a bit.

Then I wash with shampoo.

It helps by adding a protective layer between the shampoo and my hair.

Agree, sulfate-free shampoos won’t hurt my hair much …

But you still have to think about washing away natural oils in your hair.

I use the Lanza keratin masque and it makes my hair feel like butter.

“Another great way to achieve smooth hair without spending the big bucks is to get an intense conditioning masque that’s keratin infused. This will only last one week, but it’s a great way to introduce yourself to the treatment.” Eric Rosado
Senior stylist at Ted Gibson in New York City -

Leave In Conditioners – Don’t Let Your Hair Dry Out

Don’t forget the keratin conditioner. Let it shield your hair from heat and dirt.

This is important if you spend a lot of time outside in the sun.

A leave-in shampoo or conditioner is easy to use. Only takes 2 minutes.

And you’ll love the fast results:

  • Easy combing: It prevents tangles
  • UV protect: It protects your hair against the scorching heat
  • Use In Shower: You can use it in shower on damp hair. Saves you time
  • Light: It won’t weigh your hair down or make it look greasy
  • Focus on sections: Only target the sections that need conditioning
  • Bouncy: Feel the bounce in your hair without heavy oils
  • Moisture: When air is too dry indoors, it keeps your hair moist

Deep Conditioner For Hair

If your hair still feels dry after the first week: Use a keratin deep conditioning masque.

This deep conditioner for hair reduces breakage and split ends.

And it’s awesome. I always have one handy.

Only leave it for 15-20 minutes. A little bit goes a long way.

Dry Hair And Breakage After Keratin Treatment

You’ve probably heard horrifying stories online about the dramatic hair loss after keratin treatments.

I’ve seen them too.

For example: Jennifer Aniston had to cut her hair after her keratin treatment went wrong.

First of all, the main reason for excessively dry hair and scalp is related to Formaldehydes in your treatment.

If your treatment did not contain formaldehyde, it’s not something to worry.

For those looking for hair breakage solutions, I recommend: Lanza Oil.

Lanza Hair Products – Shampoo For Breakage

There are 3 reasons for abnormal hair breakage after keratin treatment:

  • Formaldehyde: Causes scalp skin to dry
  • Heat: Too much heat applied too close to the scalp
  • Overuse: Slathering on too much product & careless about your scalp

We strictly advise against Formaldehyde based treatments. If your treatment contained formaldehyde and you’re experiencing hair loss, consult your stylist or a dermatologist.

You should anticipate some minor hair loss for the first 2 weeks. Some hair shedding is part of the process until it gets back to normal.

If it worries you, use an anti-breakage keratin oil shampoo to keep things under control.

People call this the everyday blowout treatment.

The Lanza keratin oil is the inexpensive version of a keratin blowout. The results are instant and you can use it every day.

Use it on the ends and the edges of your hair, you’ll notice the big improvement.

One reviewer claimed to have reduced hair breakage by 60% in 48 hrs.

That’s impressive!

Use these tips below to prevent hair breakage:

  • Avoid Direct Heat: Heat makes your hair brittle
  • Gentle Cleansers: Avoid harsh shampoos. Use moisturizing ones
  • No Manipulations: Avoid twists, braids, and mechanical strains
  • Condition, Condition: Keep your hair supple & pliable
  • Cut Out Split Ends: Split ends and knots make your hair weaker
  • Stop Coloring: Commercial dye dries out your hair
  • Sleep on a silk pillowcase: Silk is friction-free
  • Baby Your Ends: The ends are the weakest parts. Give them more TLC

Keratin Hair Mask – Light & Bouncy Without Breakage

Another great way to max out the results of your blowout is to use hair masks.

The Ion Keratin Smoothing Mask is a total steal for your hair.

This will make your hair feel like you just came back from the salon.

And you can’t beat the price!

For DIY lovers, here’s a simple recipe:

Homemade Keratin Mask For Hair (Quick Recipe)

What you need:Instructions:
  1. Mix: Mix all of them
  2. Apply: Apply to scalp and hair
  3. Massage: Massage well for a few minutes
  4. Leave On: Let it sit for 25 minutes
  5. Rinse Off: Rinse well with cool water

And Tada! You’ve just made your first hair mask.

Itchy Scalp, Flakes, And Dandruff

Flakes and dandruff are really embarrassing to deal with.

Unfortunately, 2 weeks after your treatment, you will see keratin coating peeling off.

It’s normal. Don’t panic.

If you can’t survive the two weeks curing period and want a quick solution:

Use the Era Organics Shampoo

Era-Organics is sulfate-free which makes it a 2-in-1 deal for washing and soothing your itchy scalp.

“Switch to a volumizing dry shampoo. It will strip your roots of natural oil, resulting in less grease.” Paul Labrecque
Owner of Paul Labrecque Salons and Spas, in New York City -

Here are some good tips from hairsylists:

  • Condition The Bottom: Condition only the bottom half of your hair
  • Dry Shampoo On The Roots: Dry shampoo on the roots 2X daily
  • Avoid Brushing Your Hair: Brushing simulates oil glands

That’s right:
