1. LuxeOrganix Sulfate Free Shampoo

Sulfate-free shampoo for dandruff after keratin treatments.


Yes, Keratin Treatments Can Give You Dandruff!

Like any other chemical treatment, a keratin treatment uses alkaline agents to flex the cuticles down and make your hair glossy.

While most of these treatments are safe, you or your hairdresser must use the right amount during the application.

Using too much of the solution in your hair can cause protein overload. The excess protein then dries out to cause flakes and buildup in your hair.

Excess protein buildup can also happen if the treatment is applied too close to the scalp. Keratin treatments must be applied 1 inch away from the scalp.

Over time, the excess buildup (mostly dirt), encourages fungus bacteria to grow and feast on.

Another reason for dandruff after a keratin treatment is improper pH balance.

ph and dry scalp

The hair and scalp are both slightly acidic by nature, sitting in a range of 3.5 – 5.5.

This pH range is crucial as it prevents the growth of harmful bacteria and maintains the hair and scalp at an optimal hydration level.

When pH balance is disturbed, the acid mantle on the scalp becomes sensitive, therefore making it vulnerable to infection.

Alkaline chemicals in hair treatments often raise the hair and scalp pH beyond their safe levels without restoring balance.

When done correctly, your hairdresser would use a pH balancing shampoo right after the treatment to treat your hair.

Or if you do a DIY keratin treatment at home, you would get a post-keratin treatment shampoo.

Missing this critical step is what causes your hair to remain alkaline, causing extreme dehydration of the scalp combined with a chemical buildup that causes dandruff and itchiness.

Now, if you’ve just had your keratin treatment done and you’re suffering from chronic dandruff, all you have to do is fix those 2 problems.


Use a shampoo that can do all of these in one:

  • Deep cleanse all the leftover chemicals
  • Restore the pH of your scalp
  • Doesn’t strip off the freshly applied keratin
  • And doesn’t strip moisture from your hair

Why Use A Sulfate-Free Anti Dandruff Shampoo On Keratin Treated Hair?

Dealing with dandruff is frustrating.

And oftentimes, it leads to desperate measures that work to eliminate dandruff, but not benefiting your keratin treatment.

Let me explain …

Most dandruff shampoos contain a high level of sulfates and other ingredients like Coal Tar, Sodium Chloride, Salicylic acids, and Ketoconazole.

These harsh ingredients are like kryptonite to keratin and color treatments. They will neutralize and effectively remove all the good stuff you’ve put into your hair.

While anti-dandruff shampoos are super effective against white flakes and dry scalp, they do harm your expensive blowout. They can strip layers of keratin with their harsh ingredients.

The best way to protect your keratin treatment and get rid of dandruff is to choose your shampoo wisely.

Choose a shampoo that can do both.

In Conclusion

Looking for the right sulfate-free dandruff shampoo for keratin-treated hair without the harmful chemicals might seem daunting with so many things to consider at once.

But, knowing why and which things to avoid can make the selection a lot easier.

The bottom line is to know why you are getting dandruff after your keratin treatment. Identify which products work to solve the problem without compromising on your expensive salon treatment.

By being savvier, you’ll be able to save yourself a lot of trouble and also a lot of tears.
