About Keratin Smoothing
The languages only differ in their grammar, their pronunciation and their most common words. Everyone realizes why a new common language would be desirable: one could refuse to pay expensive translators. To achieve this, it would be necessary to have uniform grammar, pronunciation and more common words. If several languages coalesce, the grammar of the resulting language is more simple and regular than that of the individual languages. The new common language will be more simple and regular than the existing European languages. It will be as simple as Occidental; in fact, it will be Occidental. To an English person, it will seem like simplified English, as a skeptical Cambridge friend of mine told me what Occidental is.The European languages are members of the same family.
Their separate existence is a myth. For science, music, sport, etc, Europe uses the same vocabulary. The languages only differ in their grammar, their pronunciation and their most common words. Everyone realizes why a new common language would be desirable: one could refuse to pay expensive translators.
How it Works
Double Shampoo and Blow-Dry
The process begins with a double shampoo to completely strip away dirt, oil, grime, or products. Next, my hair was blown dry (the stylist used an assistant to speed the process up a bit — and I have to say I’ve never felt more pampered than having two women working in tandem with blow dryers).
Apply Treatment and Wait
After my hair was 80 percent dried, O’Connor sectioned my hair into three parts and began applying the treatment itself — a 1:1 ratio of Shape Medium (to control frizz) and the Smooth Intense (to straighten the curl). After painting the mixture onto my entire head, the solution was left to sit for 15 minutes.
Blow-Dry (Again)
Then came the fun part. O’Connor blow-dried my hair while the solution (which felt like a leave-in conditioner) was still in it, using a wide, ventilated paddle brush to do so. Given the thick consistency of the product, it took quite a bit of time.
Shampoo, Seal, and Blow-Dry
Once the hair was completely dry, it hung straight from the scalp with no need for touch-ups. The texture was smooth and silky, and you bet I spent the entire evening running my hands through it like I was Selena Gomez in a Pantene commercial.

Benefits of a Keratin Treatment
- Works on all hair types
- Has restorative properties
- Formaldehyde-free
The treatment I received is the Kerasilk Control Smoothing Service. Essentially, it involves applying a solution with high concentrations of keratin to twice-washed hair. The keratin seeps down into hair’s pores and is heat-sealed with a flat iron, leaving you with smooth, straight tresses. The downside? This specific treatment is only available at Goldwell salons, so you’ll have to do your research.

Quick answers to questions you may have
What is a Keratin Treatment?
A keratin treatment is a chemical process that smooths and shines frizzy hair. Keratin is a protein that naturally occurs in hair, and the treatment works by replenishing this protein, which can be lost due to styling, aging, and environmental factors.
Can I Use Keratin Treatments on Colored or Chemically Treated Hair?
Yes, keratin treatments can be used on colored or chemically treated hair. In fact, they can help improve the texture and appearance of chemically treated hair by adding strength and shine.
How Long Does a Keratin Treatment Last?
Typically, the effects of a keratin treatment last between 2 to 6 months, depending on your hair type, the products you use, and how often you wash your hair.
What Are the Aftercare Requirements?
- First 48 Hours: Do not wash your hair, tie it up, or tuck it behind your ears for at least 48 hours after the treatment to allow the keratin to fully bond.
- Long-Term Care: Use gentle, sulfate-free hair care products and avoid swimming in chlorinated or saltwater pools without protecting your hair.
